Photosynthesis in higher plants

237985 Phenomenon which converts light energy into chemical energy is:

1 respiration

2 photosynthesis

3 transpiration

4 none of these

Explanation:

B Photosynthesis literally means 'synthesis using light'.
$6 {CO}_{2} + 12 H_{2} O \underset{Chientingll}{⟶} C_{6} H_{12} O_{6} + 6 H_{2} O + 6 {CO}_{2} ↑$
In this process, the green part of the plant captures photons of light and converts their radiant energy into a chemical form of energy.

237986 Energy transfer in photosynthesis occure as:

1 phycoerythrin

\to

phycocyanin

\to

carotenoid

\to

Chlorophyll-a

2 chlorophyll-b

\to

carotenoid

\to

phycoerythrin

\to

carotenoid

\to

chlorophyll-a

4 chloroiphyll-b

\to

carotenoid

\to

phycocyanin

\to

chlorophyll-a

Explanation:

C The energy transfer sequence in photosynthesis is: Phycocyanin $\to$ Phycoerythrin $\to$ carotenoid $\to$ chlorophyll-a.
This sequence describes how light energy is absorbed and transferred among pigment to eventually reach chlorophyll-a, which is crucial for photosynthesis.

Photosynthesis in higher plants

237988 In photosynthesis there is

1 reduction of

H_{2} O

2 oxidation of

H_{2} O

3 oxidation of

{CO}_{2}

4 oxidation of

{NO}_{2}

Explanation:

B In photosynthesis, oxidation of $H_{2} O$ take place, which means it loses electrons and reduction of ${CO}_{2}$ , which means it gains electrons. The process of photosynthesis is commonly written as:-
$6 {CO}_{2} + 6 H_{2} O ⟶ C_{6} H_{12} O_{6} + 6 O_{2}$
