The cell theory is the theory that all organisms are made of cells. The cell is the most basic function of life and come from another cell. We have to use a microscope too see cells with the human eye. Cells are divided into two categories, eukaryotic cells and prokaryotic cells. Eukaryotic cells are larger, compartmentalized; nucleus is bound to a membrane, organelles bound to a membrane, and cytoplasm in between the spaces. Nucleus contains most of the cell’s genesNuclear envelope contains the nucleus. Nuclear membrane is a double-layered membrane witha lipid bilayer. The cytoskeleton is in the nuclear lamina, issues with the nuclear lamina cause progeria.Endomembrane system contains:Nuclear envelopeEndoplasmic reticulum Golgi apparatus- sorting and shippingLysosomes-digestion Vacuoles Plasma membrane Prokaryotic cells do not have a
