cells

ribosomes

make proteins

lysosome

an organelle in the cytoplasm of eukaryotic cells containing degradative enzymes enclosed in a membrane.

Golgi apparatus

an organelle, consisting of layers of flattened sacs, that takes up and processes secretory and synthetic products from the endoplasmic reticulum and then either releases the finished products into various parts of the cell cytoplasm or secretes them to the outside of the cell.

nucleus

control center

smooth endoplasmic reticulum

has no ribosomes; The smooth endoplasmic reticulum (SER) has functions in several metabolic processes, including synthesis of lipids and steroids, metabolism of carbohydrates, regulation of calcium concentration, drug detoxification, attachment of receptors on cell membrane proteins, and steroid metabolism.

Rough endoplasmic reticulum

has ribosomes; a network of tubular membranes within the cytoplasm of the cell, occurring either with a smooth surface (smooth endoplasmic reticulum) or studded with ribosomes (rough endoplasmic reticulum) involved in the transport of materials.

centriole

occurs in mitosis; separate of chromosomes

mitochondrion

power house of the cell

nucleolus

the inner part of the nucleus; is the nuclear subdomain that assembles ribosomal subunits in eukaryotic cells. The nucleolar organiser regions of chromosomes, which contain the genes for pre‐ribosomal ribonucleic acid (rRNA), serve as the foundation for nucleolar structure.

cytoplasm

the stuff that's in the cell; is a thick solution that fills each cell and is enclosed by the cell membrane. It is mainly composed of water, salts, and proteins.
