Answer:
Exocytosis is the reverse of endocytosis. <em><u>Quatities of material are expelled from the cell without ever passing through the membrane as individual molecules.</u></em> By using the processes of endocytosis and exocytosis, some specialized types of cells move large amounts of bulk material into and out of themselves.
Answer:
Photosynthesis is defined as the process in which the chlorophyll-containing plant
cells synthesise food in the form of carbohydrates, using carbon dioxide and water
in the presence of solar energy.
Sources of raw materials required for photosynthesis:
(a) Water is taken in from the roots of the plant and is transported to the leaves.
(b) Carbon dioxide from the air enters the leaves through the tiny pores called
stomata .
(c) Solar energy is absorbed by the chlorophyll pigment in the leaf. This energy is
used to synthesise (prepare) food from carbon dioxide and water.
Thus, photosynthesis can be represented by the following equation.
