They are made of two layers of phospholipids with proteins embedded on top or going through the phospholipids acting as a chanel

Thin layer surrounding the cytoplasm that controls the movement of substances into and out of the cell

Mesh of cellulose fibre that surrounds and supports a plant cell

Liquid filled sack like structure in a plant cell that regulates the water content of the cell and stores solutes

Discus shaped organelle containing green chlorophyll to trap light energy for photosynthesis

Fluid or jelly like background material in which may biochemical reactions occur in all cells

Unit of length that is 1000th of a metre

Sausage shaped, organelle, responsible for aerobic respiration

Large, normally spherical structure that contains chromosomes and controls the cell activities

Tiny circular structure of DNA in a bacterium that can be replicated and transferred between bacteria

Tiny structure in a cell cytoplasm that lacks a membrane and is the site of protein synthesis

Time describing the transport of molecules or ions against the concentration gradient where energy is required

The difference in concentration exists between two regions, resulting in diffusion of molecules

Structure used by a unicellular animal to remove excess water gained by osmosis

The process involving the movement of molecules or ions from a region of higher concentration to a region of lower concentration

Net movement of water molecules from a higher water concentration to a lower water concentration through a selectively permeable membrane

Term describing the transport of molecules or ions down a concentration gradient where no energy is required

Type of molecule, many of which make up a double layer in a cell membrane
