Cell Analogy About Cell Structrue & Function.
comparing and contresting cell structures of a prokaryotic cell and eukaryotic cell
Eukaryotic cell
- Eukaryotic cells possess a membrane bound nucleus are more complex than prokaryotic cells compartmentalize many cellular functions within organelles and the endomembrane system
Eukaryotic cell
Facts about Eukaryotic cell
- Humans are eukaryotes. Along with plants and animals.
- DNA is contained inside the nucleus.
- The three most important organelles in a eukaryotic cell are the nucleus, mitochondria and chloroplasts. They all contain double membranes to protect them.
- Eukaryotes can be single celled or mulitceullular (such as a dog).
Differences
- Eukaryotics cell have larger Ribosomes.
- Eukaryotics cell range from 10-100 um.
- Eukaryotics cell are in plants ans animals.
- Eukaryotics cell has a nucleus.
- Eukaryotics cell are bigger.
- Eukaryotics cells have a nueclus where DNA is stored.
Prokaryotic cell
Prokaryotic are unicellular organisms that lack organelles or other internal membrane-bound structures. Therefore, they do not have a nucleus, but, instead, generally have a single chromosome: a piece of circular, double-stranded DNA located in an area of the cell called the nucleoid
Prokaryotic cell
Facts about Prokaryotic cell
- Since DNA is not found in the Nucleus, it is instead concentrated in one area called the nuclear region.
- Some examples of prokaryotes are bacteria, or archaea.
- Prokaryotes reproduce asexually or by themselves. They can do this by binary fission (much like simple mitosis) or by budding (like a new branch budding off a young plant).
Differences
- Prokaryotic cells have free flowing DNA.
- Prokaryotic cells are small.
- Prokaryotic cells have no chloroplast, no mitochondria, and no nucleus.
- Prokaryotic cells are in bacteria and archaea.
- Prokaryotic cells have smaller ribosomes.
- Prokaryotic cells range fom 1-10 um.
Similarties
- Both contain a cell membrane (plasma).
- Both contain DNA.
- Both contain cytoplasm.
- Prokaryotic and Eukaryotic cells are both membrane bound.
- Prokaryotic and Eukaryotic cells have many forms that are different.
- Prokaryotic and Eukaryotic cells have similar basic metabolism.
Similarties
Cell Membrane
- The cell membrane is a semipermeable membrane that chooses what enters and what exits
- This is like the door of the house.
Cell Membrane
Nucleus
- stores the genetic material of the cell in the form of multiple, linear chromosomes
- in chromosomes – DNA is organized with proteins to form chromatin
- In the house, the living room is like the nucleus because its the main part of the house.
Nucleus
Ribosomes
- composed of ribosomal RNA and proteins
- the site of protein synthesis in the cell
- This is like the tools in the house that are used to make "protiens."
Ribosomes
Rough ER
- Membranes that create a network of channels throughout the cytoplasm
- This is the hallway, here you can enter throughout the house
Rough ER
Smooth ER
- relatively few ribosomes attached function-synthesis of membrane lipids calcium storage detoxification of foreign substances.
- Er is like the hallway, here you can enter throughout the house
Smooth ER
Golgi Appartus
- flattened stacks of interconnected membranes packaging and distribution of materials to different parts of the cell synthesis of cell wall components.
- Golgi Appartus is like washer and dryer. the dirty cloths are the beigining product.the end product is clean cloths afterword.
Golgi Appartus
Mitochondria
- organelles present in both animal and plant cells
contain oxidative metabolism enzymes for transferring the energy to ATP.
- The mitochondria is the power supply of cell. I compare this to the main electrical supply of the house
Mitochondria
Lysomes
- membrane bound vesicles containing digestive enzymes to break down
- This is like a Trash Can.
Lysomes
Cell Wall
- present surrounding the cells of plants, fungi, and some protists
- This is like the bricks around my house.
Cell Wall
Vacoule
Membrane-bound structures with various functions depending on the cell type
The vacuole is like refrigerator in a house. It stores water, and nutrients.
Vacoule
Cholorpast
organelles present in cells of plants and some other eukaryotes ontain chlorophyll for photosynthesis surrounded by 2 membranes thylakoids are membranous sacs within the inner membrane grana are stacks of thylakoids.
This organelle is like the solar pavel on the roof a it absorbs light into energy, the way soar panels create energy from the sun's heat.
