Phloem is the tissue in the plant system that transports the nutrition and the food materials to the plant parts. It is composed of many specialized cells like fibres, parenchyma cells, companion cells and sieve tubes.
Phloem's end walls have openings that let water and nutrients pass through them.
<h3>How does the structure of phloem help in transportation?</h3>
- The tissue of the transporting system has small openings at their end sections that allow the passage of the food and water up and down the vessels of the plant.
- The tiny holes present for the exchange of gases and water are called stomata while the root hair changes its shape to absorb water from the soil.
Therefore, option A is correct.

Explanation:
Photosynthesis Vs. Respiration
1) Photosynthesis gets it's energy from sunlight, and uses the sunlight to change water and CO2 into energy. Cellular respiration gets it's energy from glucose molecules and oxygen.
2) Photosynthesis uses energy, CO2, and water to make energy and releases oxygen. Cellular respiration uses glucose molecules and oxygen to make energy, and releases CO2 and water.
3) Cellular respiration takes place in the mitochondria, and photosynthesis takes place in chloroplasts.
Carbon, hydrogen, oxygen, nitrogen
