2.6 Water Movement: Osmosis, Tonicity, and Osmoregulation
in AP Biology
The diffusion of free water across a selectively permeable membrane, whether artificial or cellular, is called osmosis.
2.5 Membrane Transport
in AP Biology
Passive transport is diffusion of a substance across a membrane with no energy investment. Active transport uses energy to move solutes against their gradients. Bulk transport across the plasma membrane occurs by exocytosis and endocytosis.
2.4 Cell Membranes
in AP Biology
In fluid mosaic model, the membrane is a mosaic of protein molecules bobbing in a fluid bilayer of phospholipids.
2.3 Cell and Organism Size
in AP Biology
The surface-to-volume ratio is an important parameter affecting cell size and shape.

RIP for all the innocent people who lost their precious life in this terrible incident.
2.2 Subcellular Components of Eukaryotes
in AP Biology
Cells—the basic structural and functional units of every organism—are of two distinct types: prokaryotic and eukaryotic. Organisms of the domains Bacteria and Archaea consist of prokaryotic cells. Organisms of the domain Eukarya—protists, fungi, animals, and plants—all consist of eukaryotic cells.
2.1 Introduction to the Cell
in AP Biology
The cell is an organism’s basic unit of structure and function. Many forms of life exist as single-celled organisms. Larger, more complex organisms, including plants and animals, are multicellular. In this chapter, we focus mainly on eukaryotic cells—cells with a nucleus.
