Cell Organelles

nucleus

controls the processes of the cell including reproduction and protein production

nuclear membrane

selectively permeable outer covering of the nucleus

cell membrane

selectively permeable outer covering of the cell

cell wall

found in plant cells, it covers the outer part of the cell and protects it

cytoplasm

the jelly-like fluid inside the cell

ribsomes

produces proteins

nucleolus

found inside the nucleus and produces ribosomes

cytoskeleton

strands of proteins found throughout a cell that keep the cell's shape

chromatin

a mass of DNA and proteins found inside the nucleus of the cell

mitochondria

metabolizes energy for the cell

smooth ER

found around the nucleus; transports and stores fats for the cell; does not contain ribosomes

rough ER

found around the nucleus; transports and stores proteins for the cell; contains ribosomes

Golgi apparatus

packages material that is leaving the cell into vesicles

lysosome

digests waste, old cell parts, etc. for the cell

centrioles

aids in cell reproduction; produces spindle fibers that separate the chromosomes during mitosis

chloroplast

found mainly in plant cells, this organelle transforms sunlight energy into usable energy for the cell

vesicle

stores material for animal cells; associated with the Golgi

large central vacuole

found in plants, this organelle stores water for the cell
