Cell Structure - Functions Flashcards
what is the function of a cell membrane
the cell membrane controls the movement of substances into and out of the cell
how are molecules able to move through the cell membrane
molecules are able to move through the membrane ‘passively’ by diffusion or through ‘active’ transport using energy from the cell
what is the function of a cell wall
the cell wall gives strength, support and protection to the contents of plant cells, as well as giving shape to the cell thus to the entire plant
what is the function of the cytoplasm
most of the activities carried out by the cell occur in the cytoplasm
what is the function of the nucleus
the nucleus is extremely important as it controls all the cell’s functions and plays an important role in heredity, as well as containing the cell’s genetic information in the form of DNA molecules.
what is the function of the mitochondrion
the mitochondrion produces energy for the cell and is also the site of cellular respiration
what is the function of the vacuole
vacuoles in plant cells store cell sap and keep the cells firm, and in animal cells have many purposes such as control of water and storage of food particles.
