Answer :
Answer:
D
Explanation:
Photosynthesis occurs in plants and in some other autotrophs, in which they synthesize their food own-self in the presence of sunlight.
They take CO₂ from environment, water from roots and light form sun. Then they produce carbohydrate and O₂.
Chlorophyll capture sunlight and convert this into chemical energy, through which sugars are produced.
Plants produce O₂ which animals use in their respiration.
D) option is correct
Explanation:
Chlorophyll is a primary photosynthetic pigment which primarily absorb sunlight and drives photosynthesis
- Chlorophyll is simply a lipid molecule consisting of tetrapyrole ring and also contain a cyclopentanone ring fused to pyrole ring III
- In chlorophyll the central metal ion is Mg2+
- A branched hydrocarbon chain called phytol chain associated with ring IV which keeps embedded porphyrin ring in thylakoid membrane
- Chlorophyll a and b are more common photosynthetic pigments
