A quadrat is a simple device for marking out a small area. For young children at primary school the quadrat is often a convenient way of focusing a pupil's attention on a particular small area. At secondary level, pupils should understand how quadrats can be used to sample a larger area. By recording information from a number of quadrats placed within a larger study area, they can obtain a representative sample of the whole area, which may be too big to describe in full.
The algae living in the tissues of coral animals are called photosynthetic algae. The purpose of the the photosynthetic algae is to produce oxygen and help the coral to remove wastes. Coral on the other side provides the algae with a protected environment and compounds they need for photosynthesis. The algae supply the coral with the product from the photosynthesis which are glucose, glycerol, and amino acids.
Receptor potential is generally at the receiving region. The receptor potential(also called generator potential) can work to trigger an action potential either within the same neuron or adjacent cell.Within the same neuron the receptor potential causes local current flow to the region responsible for action potential.
