Nucleus: CONTROL CENTER
Cytoplasm: PRODUCTION DEPARTMENT,
where cells activities take place
Membrane: outer surface containing protoplasm.
As each cell absorbs food, it grows and divides creating two new cells — this is called…

The chemical process in which cells receive nutrients for cell growth and reproduction
Metabolism
Tissue that COVERS and protects body surfaces and internal organs
Epithelial

Nerve tissue
Tissue that when stimulated produces motion
Muscle tissue
