Question

The process of photosynthesis take place in
A.Roots only
B.Shoot only
C.All the cells of the plant
D.Chlorophyll containing cells only

Answer 1

Photosynthesis is the only method by which organisms can manufacture their own food from inorganic materials. They take the help of solar energy. Photoautotrophs exhibit photosynthesis. Green plants, red algae, brown algae, protists, cyanobacteria fall under this category. Heterotrophs are organisms that cannot synthesize their own food and depend on autotrophs for food.

Complete answer: Roots are involved in the holding of a plant and storage of food.
Shoots give rise to stems, leaves, and flowers and are responsible for the production of food and reproduction.
In eukaryotic autotrophs, chloroplasts are the sites of photosynthesis. Chloroplasts are green plastids and are mostly present in leaves. Thylakoids are flattened membranous sacs present in the matrix or stroma of a chloroplast. Chlorophylls are photosynthetic green pigments present in the thylakoid of the chloroplast and are of five types. These are chlorophyll a,b,c,d and e.
Chlorophylls a and b occur in the chloroplast of higher plants. Chlorophyll a is termed as the universal photosynthetic pigment because it is present in all photosynthetic plants except for bacteria. Due to its performance of primary reactions of photosynthesis, it is also referred to as the primary photosynthetic pigment. all the other photosynthetic pigments are known as accessory pigments.
While chlorophyll a is bluish-green in the pure state, chlorophyll b is olive green in the pure state. Chlorophyll a and b solubilize in a number of organic solvents. Chlorophyll a is more soluble in petroleum while chlorophyll b solubilizes in ninety-two percent of methyl alcohol.
Thus, the correct option is (D) Chlorophyll containing cells only.

Note: Some important facts about chlorophyll are:
The energy that chlorophyll absorbs from sunlight is converted into two kinds of energy-storing molecules. The energy thus gained is used for photosynthesis.
In photosynthesis, carbon dioxide and water are converted into a type of sugar called glucose by the utilization of the stored energy.
