Answer:
It depends on the structure of labeled A.
Explanation:
If the diagram shows the structure of flower, so we can say that it has the ability to attract insects and other animals. If the diagram shows the structure of an insect such as bees so we can say that it can moves the pollen to the ovaries. If the diagram indicates the structure of pistil which is a female part of the flower so we choose that it catches the pollen and if the diagram represents the structure of anther which is a female part so we choose that it produces pollen.
Active transport is the movement of dissolved molecules into or out of a cell through the cell membrane, from a region of lower concentration to a region of higher concentration. The particles move against the concentration gradient , using energy released during respiration .
