◉ eukaryotic cell. Answer: A cell with a nucleus and other
membrane-bound organelles. Examples include animal and plant
cells.
◉ prokaryotic cell. Answer: A cell without a nucleus or membrane-
bound organelles. Examples include bacteria.
◉ main organelles in an animal cell. Answer: Nucleus, cell
membrane, cytoplasm, mitochondria, ribosomes.
◉ additional organelles in plant cells. Answer: Chloroplasts, cell wall,
permanent vacuole (in addition to organelles found in animal cells).
◉ function of the nucleus. Answer: Contains genetic material (DNA)
and controls the cell's activities.
◉ function of mitochondria. Answer: Site of aerobic respiration,
where energy is released from glucose.
, ◉ function of chloroplasts. Answer: Site of photosynthesis, where
light energy is used to make glucose.
◉ function of the cell membrane. Answer: Controls what substances
enter and leave the cell (selectively permeable).
◉ function of ribosomes. Answer: Site of protein synthesis.
◉ function of the cell wall. Answer: Provides structural support and
protection for the cell.
◉ function of the permanent vacuole. Answer: Contains cell sap to
help maintain turgor pressure.
◉ stem cell. Answer: An undifferentiated cell that can develop into
many different cell types.
◉ differentiation. Answer: The process where cells develop to
become specialized for specific functions.
◉ diffusion. Answer: The movement of particles from an area of
higher concentration to an area of lower concentration.
◉ osmosis. Answer: The diffusion of water molecules across a
partially permeable membrane from a region of higher water
concentration to a region of lower water concentration.
