Cell Organelles

Cell organelles and their functions

nucleus directs the cell’s activities
cell membrane “gatekeeper” of the cell; controls what enters and leaves the cell
lysosome contains chemicals that break down food and worn out cell parts
endoplasmic reticulum (ER) transports proteins and other materials through the cell
mitochondrion “powerhouse” of the cell; produces energy used by the cell from glucose
ribosomes small structures where proteins are produced
vacuole storage sac for water, nutrients, and waste
cell wall a rigid layer of non-living material that surrounds the cell; provides protection and support
chloroplast captures energy from the sun to produce food (glucose)
cytoplasm gel-like material between the cell membrane and the nucleus; holds the organelles
nucleolus organelle inside the nucleus where ribosomes are made
chromatin (chromosome) contain the cell’s genetic material
Golgi body receive materials from the ER and packages them for transport within or outside the cell
nuclear membrane controls what enters and exits the cell’s nucleus
