- le compartiment
- compartment
- Endoplasmic Reticulum
- An extensive system of membranes inside eukaryotic cells that direct molecular traffic
- Nucleus
- The largest organelle directs the cells activities and contains the cell’s genetic material
- Golgi Apparatus
- Packages, labels and distributes molecules made in the cell/ contains enzymes that act on proteins and lipids
- Cytoskeleton
- a network of protein fibers that supports the shape of the cell and anchors its organelles
- Nuclear Pores
- Shallow depressions, which contain proteins and permit certain molecules to pass into and out of the nucleus
- Nuclear Envelope
- Double lipid bilayer membrane that surrounds the nucleus
- Plasma Membrane
- Lipid bilayer membrane embedded with protein that surrounds the cell
- Ribosomes
- Made up of proteins and RNA these molecules sit on the ER and manufacture proteins that are later exported
- Mitochondria
- Organelles which release the stored energy in food. May have evolved from bacteria
- Vesicles
- Membrane enclosed sacs created by the ER found only in eukaryotic cells
- Smooth ER
- The endoplasmic reticulum where lipids are made/ numerous in brain cells
- Lumen
- Proteins and lipids that are being made for export pass into this compartment before moving on to the smooth ER
- Rough ER
- The endoplasmic reticulum that is covered with ribosomes
- Central Vacuole
- A large internal space found in plant cells/ stores water, nutrients or wastes/ Pressure from the water keeps plants from wilting
- Chromosomes
- Rod shaped structures in the nucleus composed of DNA and proteins
- Actin Filaments
- Provide the cell with mechanical support and give it shape. Moves things like organelles and molecules around within the cell
- Intermediate Filaments
- Provide the cell with mechanical support and give it shape. Forms a scaffolding for the cell
- Peroxisomes
- Small vesicles derived from smooth ER, which contain enzymes. They may convert fats to carbohydrates or form H2O2
- Flagella
- Long threadlike organelles protruding fro the cells surface. Composed of a circle of 9 microtubules surrounding two central microtubules
- Microtubules
- Hollow protein fibers which form centrioles or flagella or cilia
- Cilia
- Flagella that are shorter, numerous, and organized in tightly packed rows.
- Centrioles
- Structures made of microtubules which aid in moving chromosomes during cell division. Not found in plants or fungi.
- Lysosomes
- Vesicles that contain digestive enzymes to break down proteins, nucleic acids, lipids (fats), and carbohydrates. Recycle the cell’s used components
- Chloroplasts
- Perform photosynthesis, to make sugars from water, CO2, and energy from sunlight
- Cell Wall
- Rigid structure outside the plasma membrane made of cellulose or chitin
- Cytosol
- The fluid portion of the cytoplasm
- Cytoplasm
- Everything inside the cell membrane except the cell’s genetic material
- Plastids
- Chloroplasts, leucoplasts, and chromoplasts are examples. They are plant organelles containing pigments, starches or lipids
- Nucleolus
- Region within the nucleus that produces ribosomes
