bibliography on photosynthesis​

Answer 1

Answer:

Introduction

photosynthesisfō˝tōsĭn´thəsĭs [key], process in which green plants, algae, and cyanobacteria utilize the energy of sunlight to manufacture carbohydrates from carbon dioxide and water in the presence of chlorophyll. Some of the plants that lack chlorophyll, e.g., the Indian pipe, secure their nutrients from organic material, as do animals, and a few bacteria manufacture their own carbohydrates with hydrogen and energy obtained from inorganic compounds (e.g., hydrogen sulfide) in a process called chemosynthesis. However, the vast majority of plants contain chlorophyll—concentrated, in the higher land plants, in the leaves.

In these plants water is absorbed by the roots and carried to the leaves by the xylem, and carbon dioxide is obtained from air that enters the leaves through the stomata and diffuses to the cells containing chlorophyll. The green pigment chlorophyll is uniquely capable of converting the active energy of light into a latent form that can be stored (in food) and used when needed.

Answer 2

Answer:

Photosynthesis is a chemical reaction that takes place inside a plant, producing food for the plant to survive.Carbon dioxide, water and light are all needed for photosynthesis to take place.Photosynthesis happens in the leaves of a plant.Plants need food to respire, grow and reproduce. Unlike animals, plants are able to make their own food by the process of photosynthesis.Photosynthesis takes place in the part of the plant cell containing chloroplasts, these are small structures that contain chlorophyll.Carbon dioxide enters through the stomata on the underside of the leaf.Water is absorbed by the root hair cells and is transported to the leaf by the xylem vessels.Sunlight provides the energy needed for photosynthesis to take place. In this process carbon dioxide and water are converted into oxygen (a waste product that is released back into the air) and glucose (the source of energy for the plant).Oxygen is released through the stomata on the underside of the leaf; glucose is transported around the plant in the phloem vessels.
