organelles and cell divison

Cytoplasm

Contains cytoskeleton which provides structure to the cell and anchors the organelles

Nucleus

DNA and assorted proteins are stored here, surrounded by a nuclear envelope which can make nuclear pores

Nucleous

A condensed area within the nucleus which creates ribosomes

Ribosomes

Where protein synthesis occurs, composed in the nucleous and then released into the cytoplasm to react with the mRNA

Rough Endoplasmic Reticulm

Is a membrane attached to the nucleus that has ribosomes on it. It synthesizes phospholipids for the cell membrane.

Smooth Endoplasmic Reticulm

Does not have ribosomes attached, manufactures lipids and some steroids.

Golgi Apparatus

Flattened sacks containing cisternae, modifies, packages, and distributes lipids and proteins from SER and RER.

Secretory Vesicles

Small membrane bound pouches that pinch off from the golgi and move toward the surface of the cell.

Lysosomes

Contains enzymes that digest foreign material that is brought into the cell by phagocytosis

What is phagocytosis?

A process that kills bad cells in the body and engulfs bacteria’s and tissues

Perioxisomes

Contains enzymes that ditoxifys alcohol, perioxides, and other chemicals
