Explanation: The guard cells helps in controlling the size of stomata. Guard cells are special type of cells that lies in the epidermis of the leaves.
These cells controls the loss of water by changing the shape and size of stomata. The stomatal pore is largest when there is abundant of water available for uptake.
But when there is loss of water, the guard cells become flaccid and prevents the loss of water.
The number of offspring produced is often related to the amount of parental care. Typically, the higher fecundity, the lower the amount of time parents devote to caring for the offspring.
