Welcome to the biology portal! This portal is intended to be a user-friendly guide to biology content on Wikiversity for pre-school, primary and secondary levels. For a more specialist and advanced portal, please refer to the life sciences portal.
"The active transport of small molecules or ions across a cell membrane is generally carried out by transport proteins or “pumps” that are found in the membrane itself. Larger molecules and clumps of material can also be actively transported across the cell membrane by processes known as endocytosis and exocytosis. The transport of these larger materials sometimes involves changes in the shape of the cell membrane.
Plastids are subunits of plant and algae cells which are responsible for specific functions such as photosynthesis, storage of products like starch and for the synthesis of many classes of molecules.
