Transcript: Nucleus The nucleus is like the principal. A nucleus directs the activities of all the other organelles. The Principal directs the activites of all the students within the school. Cytoplasm Cytoplasm is like teachers. Cytoplasm controls the cell metabolism and is full of proteins. Teachers are full of knowledge and control the classroom. Ribosome Ribosome is like classrooms. Ribosomes is a site of the making of proteins. Classrooms are the site of the place where we learn. Mitochondria Mitochondria are like cooks. Mitochondria provides energy. The cooks provide us with food which gives us energy! Vacuole Vacuole are like bathrooms! Vacuole plays a role in the release of cellular waste products. Bathrooms play a role in our waste products Golgi Body Golgi Body is like a box. The golgi body packages macromolecules for transport elsewhere in the cell. A box package school supplies and transports it to the school. Rough Endoplasmic Reticulum Rough Endoplasmic Reticulum is like a backpack. Rough Endoplasmic Reticulum is a meeting place for proteins synthesized on ribosomes before they transport throughout the cell. A backpack hold our books before we transport them to class. Smooth Endoplasmic Reticulum Smooth Endoplasmic Reticulum is like a weight room. Smooth Endoplasmic Reticulum controls the calcium release in the muscle cell Contraction. The weight room relates because it helps us build our muscles. Lysosome Lysosome is like hand sanitizer. Lysosome kills and digests bacteria in the vacuole. Hand sanitizer kills the germs on our hands. Cell Membrane The cell membrane is like the security cameras. The cell membrane contains proteins that include pores that control the entry and exit of ions. A security camera watches the entry and exit of people. Cytoskeleton Cytoskeleton is like the students and staff. The Cytoskeleton maintains the cell shape and cell motility. The sudents and staff keep the school up and running.

Transcript: The main traditional food that comes from Scotland is haggis. It is a mince type of meat that ost scottish people eat but from my point of view it isnt the best. At school I would eat fish and chips some days but other days pasta etc in the school cafeteria. Lastly at home I would eat chicken and beef at home for dinner and lunch on occasions. My City and Country I am british and from the UK. I was brought up in dubai and was born there but my whole family is from scotland, brought up in a city named Glasgow, where I lived for 3 years of my life between the age of 13-16 There is a few festivals. Firstly there is TITP. Also there is tatoo festival in edinbrugh where all the pipemen play. Clothes I wear- Golf is no doubt the most famously Scottish sport. Also football is pretty big and cycling. Football is big as everyone is so passionate about it. The team I support is rangers who seemed to lose everything but they are getting back to the top. Also cycling is big as the fastsest cyclist in the world is scottish named Sir Chris Hoy. To school- School uniform in scotland is white shirt with a supplied tie from the school with the badge of the school logo on it. Black trousers with any black or white shoes. Traditional clothing in scotland- Hobbies and sports Festivals in Scotland Languages Symbols and colours that represent my Country Everyday- Theweather in scotland is mostly cold and raining so I would normally wear joggies with a jumper in the house, however when going out i would wear jeans with a smart jumper. Clothes I wear Some places in scotland they speak gaelic. No other languages are really spoke except this and english. Traditional clothing for men is the kilt. This is a skirt that men would wear to weddings and special occasions. Culture Powerpoint Food in scotland-
Transcript: Lysosoms would be compared to the garbage cans in the office because the both get rid of wast. Mitochondria Vacuole Ribosomes Lysosomes The cytoplasm would be the air in the office. Cell Analogy by Adam and River Nucleus The ribosomes are compared to the documents in the office. They stay in the office if the office needs them or leaves the office if they have to go somewhere else. the centrioles would be the copy machine in the office Cell membrane The Mitochondria would be the electricity in the office giving it energy Golgi Apparatus Our cell analogy is based off a business office The boss's office compares to a Nucleus because the boss's office stores the information for the rest of the office. The golgi apparatus would be the mail room of the office building Nucleolus Cytoplasm The Cytoskeleton would be the walls of the cubicles The cell membrane would be the outer walls of the office building keeping the outside environment from the inside. The Boss of the office compares to the Nucleolus because the boss makes the important documents. A water cooler is compared to a Vacuole because it contains the water for the rest of the office. Cytoskeleton Centrioles
Transcript: Analogy : The Great Wall of China Location : On the outside of the cell. It is basically the exterior of the cell. It seperates the contents of the cell from its exterior environment. The nucleus is the organelle that controls all the activities within the cells. It is both an animal and plant cell. Its a eukaryotic cell. Cell Membrane Function : Maintain integrity of the genes & control activities of the cell. Nucleus is the control center of the cell. Cell Membrane Nucleus Cell Organelles .. Functions : The cytoplasm offers support to the cell & speeds up inter-celluar travel. It allows the cell to take up 3D space and the cells many organelles to float freely throughout. It also acts as a medium for transport inside the cell. The cell membrane is something that lets some things in and out of the cell. Its both an animal and plant cell. Its prokaryotic and eukaryotic. Cytoplasm Cytoplasm The cytoplasm is a jelly like substance within a cell, containing organelles, water & other life supposrting materials. It is both an animal & plant cell. Its eukaryotic cell. Nucleus Location : In the centre of the animal cell & plant cell. Analogy : The brain. Cell Membrane Function : Seperates the interior of cells from the outside enviroment. Its basically protect the cell from outside voices. Cytoplasm Nucleus Location : Fluid inside the cell. Analogy : Is to cell as bones are to humans. If there is no cytoplasm, there is no consistency of the cell.
Transcript: Structures formed by tubulin, the make up of microtubles Located near the nucleus Help to organize cell division and are only found in plant cells Organelles that convert the chemical energy in food into compounds that are more convenient for the cell to use Have two membranes "powerhouse" of the cell What are they? Prokaryotes VS Eukaryotes DNA Ribosomes Sack-like structure that stores materials such as water, salt, proteins, and carbohydrates Exists in both animal and plant cell but is bigger in plant cells due to their need of water and their inability to move for it There are some key organelles in both the plant and animal cell that help identify them. For example, centrioles are only found in animal cells while chloroplast and cell wall are unique to plant cells. Though no matter what, both contain cell membrane and carry DNA. Cell Wall Plant cells are more complicated than animal cells There is a major size difference between prokaryotic and eukaryotic cells Eukaryotic cells are larger and more complex. They also contain nuclei which is where their genetic information is stored Though, prokaryotic cells are smaller and have structures within themselves that are far less diverse and complicated than that of the eukaryotic cells. They do not have a nucleus and rather have free-floating genetic information Golgi Apparatus Cell PowerPoint Thin, flexible barrier that surrounds the cell It regulates what enters and leaves cell while also providing protection ad support It is composed of a lipid bilayer, studded with proteins, and most importantly, it is constantly moving in a fluid manner Organelle that modifies,sorts, and packages proteins and other materials from the ER for, either, storage in the cell or secretion outside of the cell Kind of like UPS Cytoplasm Nucleolus Network of protein filaments that help the cell to maintain its shape while also being involved in movements It consists of microfilaments and microtubules, distinct protein filaments that aid in the holding up of the cell Cytoskeleton Unique powerhouse of plant cells Captures the energy from sunlight and converts it into chemical energy in a process called photosynthesis Contain their own genetic information Strong supporting layer around the membrane of plant cells, which allows certain substances to pass through It's main function is to provide protection and support for the cell in question Made from fibers of carbohydrate and protein and are mostly made of cellulose, the base ingredient in paper Response:Yes, plant cells are more complicated than animal cells do to the fact that it has more structures which withhold the cell and identify it. For example, the cell wall is a feature that can distinguish a plant cell from an animal cell as well as chloroplast, the intricate power source of plant cells. Cell Membrane Cytoplasm is basically cell goo/gel It is an area of the cell outside of the nucleus or, in the case of a prokaryotic cell, the stuff that the DNA and the other cell organelles float in It keeps the organelles from crushing or hurting themselves, for it acts like a cushion Vacuole The carrier of genetic information specific to each cell in question It is found inside the nucleus, the control center of the entire cell, but more specifically is the make up chromatin it stands for deoxyribonucleic acid Animal Cells Cytoskeleton Centrioles Nucleus Mitochondria By: Julian Perez P.3 Inside a Prokaryote Claim: Control center of the entire cell Contains basically all of the cell's DNA and instructions to make proteins and other significant molecules Covered with a double membrane called a nuclear envelope Distributes important information to the whole cell Chloroplast Site where lipid components of the cell membrane are assembled, along with proteins and other materials that will leave the cell Like Tesla, for it uses small parts to make big things Consists of both smooth (isn't covered with ribosomes) and rough (covered with ribosomes) Prokaryotes are cells that don't have a nucleus. The greek origins of the word suggest that the cell evolved before a nuclei could develop. Instead, their DNA is not contained in a nucleus and they are generally less complicated than eukaryotes. This does not mean that they are "disabled" for they can still grow, reproduce, and respond to their environment, activities commonly associated with living things. Bacteria are examples of prokaryotes. Cell Membrane Small organelles filled with enzyme The "janitors" of the cell They remove organelles that are past their prime Lysosomes also break down lipids and carbohydrates so they they can be used by the rest of the cell Lysosome Ribosomes make/assemble proteins and are found floating in the cytoplasm They are smalle pieces of RNA and protein and are attached to the endoplasmic reticulum Small and dense region within the nucleolus Where the assembly of ribosomes begins Plant Cells Centrioles Endoplasmic Reticulum Plant cells consist of many organelles
