- What do golgi apparatus do?
- contains enzymes that attach carbohydrates and lipids and proteins
- Cytoskeleton?
- network of protein filaments tha thelp the cell to maintain its shape
- What are Ribosomes?
- organelle that assembles proteins
- Endoplasmic Reticulum?
- organelle where components of cell membrane are assmebled and some proteins are modified
- Lysosomes?
- organelle that are filled with enzymes to break down carbohydrates, lipids and proteins from food.
- vacuoles
- store water
- nucleolus?
- small region of nucleus assembles ribosomes
- nuclear envelope?
- double membrane surrounding the nucleus
- chromatin?
- granular material visible within nucleus
- chromosomes
- condensed form of chromatin, threadlike structures containing genetic information that is passed from one generation of cells to the next
- chloroplasts
- only in plants use energy from sunlight to make food
- mitochondria
- use energy from food to make high-energy compounds that the cell can use to power growth, development, and movement
- what is facilitated diffusion?
- process by which molecules that can't pass through the lipid bilayer
- What is active transport?
- transfer of molecules from an area of lower concentration to an area of higher concentration requiring input of energy
- what is endocytosis, phgocytosis and exocytosis
-
endocytosis- process of taking material into cell by means of pockets of cell membrane
phagocytosis- when large particles taken into cel by endocytosis extensions of cytoplasm surround and engulf large particles
exocytosis- removal of large amoujnts of material from the cell
