Answer 1

Answer:

a green plants prepared their food by absorbing carbon dioxide and water from the sunlight in the region of chlorophyll is called photosynthesis

Answer 2

Answer:

1. Photosynthesis is the process by which plants and other things make food. It is an endothermic (takes in heat) chemical process that uses sunlight to turn carbon dioxide into sugars that the cell can use as energy. As well as plants, many kinds of algae, protists and bacteria use it to get food.
2. This part of the plant is called its food factory because it produces food for the plant using sunlight, water and carbon dioxide.
3. To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight. for photosynthesis. Carbon dioxide enters through tiny holes in a plant's leaves, flowers, branches, stems, and roots. Plants also require water to make their food.
4. Photosynthesis is the process by which photosynthetic organisms (Green plants, algae, photosynthetic bacteria) capture light from the sun and is converted into the chemical energy, in the form of carbohydrate (starch)
5. with the help of atmospheric carbon dioxide and water to carry out vital functions of living things.
6. The basic substances for photosynthesis are Chlorophyll, Sunlight, Carbon dioxide, and Water.
7. Chlorophyll: It is a green color pigment, present in the chloroplast of the plant cell. The two components of Chlorophyll a, PSI (photosystem I) and PSII (photosystem II) absorbs sunlight and the captured energy further used to split the water molecules.
8. Sunlight: Photosynthesis is a light-dependent process; thus, the specific wavelength of sunlight (red and blue) excites the photoreceptor (chlorophyll) to carry out the photo-chemical reaction.
9. Carbon dioxide: This gas is abundantly present in the atmosphere. Plants absorb carbon dioxide through the small openings present on the leaf surface, known as stomata.
10. Water: Plants absorb required water from the ground through their roots, and water transported to the leaves via stem through a complex transport tissue, the xylem.
11. The food that is prepared by the plant is utilized for its metabolic processes, the excess food is stored in the form of starch, in the plants. ... The plants prepare starch by a process of photosynthesis with the sunlight along with "water and carbon dioxide".
12. Foraging, flying or crawling insects such as flies are attracted to a cavity formed by the cupped leaf, often by visual lures such as anthocyanin pigments, and nectar bribes. The rim of the pitcher (peristome) is slippery when moistened by condensation or nectar, causing insects to fall into the trap.
