Cell Structures and Functions Flashcards
Movement of molecules (usually water) from high concentration to low concentration through a membrane
Osmosis
“Mail men,” small membrane bound sacs that transport materials around cell and to cell membrane
Vesicles
Made of protein microtubules and microfilaments
Cytoskeleton
Plant cells have large one to store water
Central vacuole
“Quality control”, Modifies and Processes proteins made by the cell.
Golgi body
Enzyme vesicle. Breaks down larger food molecules into smaller molecules; digests old cell parts
Lysosome
“Powerhouse” or “Energy producer”; makes ATP through cell respiration
Mitochondria
Assembles amino acids into proteins.
Ribosome
“warehouse,” stores food, water, waste; larger in plant cells
Vacuole
“Border control”, controls what comes in and out
Cell membrane
Gives support and protection to cell; made of cellulose in plants.
Cell wall
Movement of molecules from high concentration to low concentration
Diffusion
“Cell highway”, transports goods and materials throughout the cell, 2 types
Endoplasmic reticulum
Where photosynthesis occurs; in plant cells
Chloroplast
Jelly-like substance the cell organelles float in
Cytoplasm
