ransom chapter 3 organelles
organelle | function | other facts |
---|---|---|
cell membrane | keep cytoplasm in, allow nutrients and waste out | all cells have it |
cell wall | provide strength and support to cell membrane | only in plants and algae |
nucleus | holds the cells' DNA | called the control center |
nucleolus | stores materials that will be used to make ribosomes | found in the center of the nucleus |
ribosomes | makes proteins from amino acids | the smallest but most abundant organelle |
endoplasmic reticulum (ER) | makes lipids and breaks down drugs | only in eukaryotic cells; called the internal delivery system |
mitochondria | breaks down food to make ATP | needs oxygen |
chloroplasts | photosynthesis occurs here | only found in plants and algae |
Golgi complex | processes, packages, and transports materials sent from ER | called the cell's packaging center |
vesicles | membrane covered compartments in eukaryotic cells | forms when part of the cell membrane surrounds an object and pinches off |
vacuoles | store water and other liquid | much larger in plant cells than animal cells |
lysosome | digests food particles, wastes and foreign invaders | a type of vesicle |
