What five things does an animal cell contain?
Nucleus Cytoplasm Partially permeable membrane Mitochondria Ribosomes
What is the Nucleus
Contains genetic material which are arranged into chromosomes
What is cytoplasm
A gel like substance where most chemical reactions occur also contains enzymes that control these chemical reactions
What is a partially permeable membrane
Holds the cell together and controls what goes in and out of the cell
What is the mitochondria
Where aerobic respiration occurs respiration transfers energy that the cell needs to work
