Cells Flashcards

chloroplast: makes food for plant cells, photosynthesis
mitochondria:produces energy the cell needs to carry out its functions; release energy
vacuole: stores food, water, and waste
lysosome: found mainly in animal cells, digests old cell parts
endoplasmic reticulum: carries proteins and other materials from one part of the cell to the other
cytoplasm: gel -like fluid where the organelles are found
nucleolus: makes ribosomes, center of the nucleus
ribosome: makes proteins
cell membrane:controls what comes into and out of the cell, found in plants and animals
nucleus: controls cell activity
cell wall: protection and support for plant, not animal cells; rigid outer layer
