In order for plants to make their own food, they must go through a process called photosynthesis. This process occurs in the chloroplasts of a cell. To begin this process, all items needed must go to the cells of a plant. Water and nutrient are absorbed from the soil through the roots. A tube called the xylem carries only water up the stem to the rest of the plant. Gas exchange in the plants occur in the tiny pores of a leaf called the stomata. This is opened and closed by the guard cells. The food produced by this process is called ATP and it is a macromolecule known as a nucleic acid.
Answer:
The correct answer is option 4. Parasympathetic division.
Explanation:
The parasympathetic division is one of the three divisions of the ANS or autonomic nervous system. It also helps in the rest system or digest system as it saves energy by slowing the heart pace by slowing the rate of contraction. This is performed with the help of nerve fibers that send signals.
Parasympathetic nerve division increases the intestinal and activity gland. This nerve division helps in relaxing the sphincter muscle in the GI tract.
