Excretion – All living things get rid of waste products from chemical reactions

Reproduction – All living things make offspring to continue their species

Growth – All living organisms grow (get bigger)

Animal Cells (multicellular organism) store carbohydrates as glycogen

A – Nucleus – for nervous coordination, controls functions within the cell. B – Cytoplasm – Where most chemical reactions inside the cell take place. C – Cell Membrane – partially permeable membrane that controls what enters and exits the cell D – Mitochondria ­– Where aerobic respiration occurs
