Animal & Plant Cells Flashcards

All 7 cards in this deck

What parts are found in most animal cells?: A nucleus, cytoplasm, a cell membrane, mitochondria and ribosomes.
What is the function of the nucleus?: It contains the genetic material (chromosomes/DNA), which controls the activities of the cell.
What is the function of mitochondria?: They are where aerobic respiration takes place, releasing energy for the cell.
What is the function of the cell membrane?: It controls the movement of substances into and out of the cell.
What is the function of ribosomes?: Protein synthesis — they are where proteins are made.
What structures do plant and algal cells have in addition to the parts found in animal cells?: Chloroplasts (photosynthesis), a permanent vacuole filled with cell sap, and a cell wall made of cellulose that strengthens the cell.
True or false? Every plant cell contains chloroplasts.: False. Only cells exposed to light, such as leaf mesophyll cells, have chloroplasts — root hair cells, for example, do not.
