Transcript of Cell Organelles

Organelles
"Tiny Organs"

Essential Questions: What's inside of a cell? What do organelles do?
Cell Wall
Provides structural support; made of the carbohydrate cellulose
Nucleus
Contains the cell’s DNA (coded instructions for making proteins and other important molecules) in the form of chromosomes or chromatin
Mitochondria
Cell membrane
Separates the inside of the cell from its environment; allows only certain things into and out of the cell
Found in: prokaryotes, eukaryotes (plants, animals, fungi)
Found in: plants, fungi, and some prokaryotes
Found in all eukaryotic cells (plant, animal and fungi)
Cytoplasm & Cytoskeleton
cytoplasm: semifluid environment inside of a cell; cytoskeleton: network of long thin protein fibers that hold organelles in place
Found in prokaryotes, eukaryotes (plant, animal, fungi)
cytoskeleton only in plant and animals)
flattened stack of membranes that sorts, modifies, and packages proteins to be packed into vesicles which can cross the cell membrane
Golgi Apparatus
All eukaryotic cells (plant, animal, fungi)
Nucleolus
Small, dense region of the nucleus where ribosome production begins
Convert carbohydrates (sugar) into usable energy (ATP) which the cell then uses; folded to increase surface area
Found in all eukaryotic cells (plant, animal, fungi)

Ribosomes
Lysosomes
Centrioles
Cilia & Flagella
Chloroplasts
Vacuole
Found in plant and animal cells
storage of water, nutrients, and waste products
Found in plants
contain chlorophyll; convert sunlight into food for the plant
Found in prokaryotic and eukaryotic cells (plant, animals, fungi)
read RNA (instructions) and assemble proteins; some ribosomes are attached to the ER and some are free
animal
Ribosome
enzyme filled sacs which break down food, old/broken organelles, or viruses which may have entered the cell
found in animal cells only
lysosomes
a pair tubes made of proteins that help the cell separate during cell division
found mostly in animal cells
animal
free
attached
hair-like structures attached to the outside of the cell membrane; allow for cell movement
found in prokaryotes and some eukaryotes
Cilia & Flagella
Endoplasmic Reticulum
folded membrane attached to nucleus where proteins are manufactured (built)
found in all eukaryotic cells (plant, animal, fungi)
Rough ER - ribosomes attached
Smooth ER - no ribosomes
