Cell Organelles Flashcards
controls movement of substances in and out of cells
cell membrane
contains all organelles and other life-supporting materials
cytoplasm
acts as the “brain”
nucleus
encloses nucleus
nuclear membrane
makes ribosomal subunits from proteins and ribosomal RNA
nucleous
efficiently “packs” DNA into a small volume to fit in the nucleus
chromatin
manufacturing and packaging system
endoplasmic reticulum
acts as the site of assembly for mRNA, amino acids containing tRNA and enzymes needed for protein synthesis
ribosomes
“powerhouse of the cell” takes in nutrients breaks them down and creates energy for the cell
mitochondria
stores water, ions, macromolecules, sugars and amino acids
vacuole
processes and packages macromolecules
Golgi body
breaking down macromolecules
lysosomes
development of spinal divers in cell division
centriole
photosynthesis
chloroplasts
protection and structure
cell wall
