Which of the following absorb light energy for photosynthesis
Which of the following absorb light energy for photosynthesis
- Chlorophyll
- Water molecule
- O2
- RUBP
The Correct Option is A
Solution and Explanation
The correct option is (A): Chlorophyll
A substance that absorbs a certain visible light wavelength is known as a pigment. Plants need chlorophyll, a green pigment found in thylakoid membranes of chloroplasts, for photosynthesis. Green plants use the energy of light to transform carbon dioxide (CO2) and water (H2O) into carbohydrates, a process known as photosynthesis. The plant's photosynthetic pigment, chlorophyll, absorbs light energy while air containing carbon dioxide and oxygen enters the plant through the stomata on the leaves.

Given below are two statements:
Statement I: Transfer RNAs and ribosomal RNA do not interact with mRNA.
Statement II: RNA interference (RNAi) takes place in all eukaryotic organisms as a method of cellular defence.
In the light of the above statements, choose the most appropriate answer from the options given below:- NEET (UG) - 2025
- RNA interference
- Given below are two statements: Statement I: In the RNA world, RNA is considered the first genetic material evolved to carry out essential life processes. RNA acts as a genetic material and also as a catalyst for some important biochemical reactions in living systems. Being reactive, RNA is unstable.
Statement II: DNA evolved from RNA and is a more stable genetic material. Its double helical strands being complementary, resist changes by evolving repair mechanisms. In the light of the above statements, choose the most appropriate answer from the options given below:- NEET (UG) - 2025

- Two gases A and B are filled at the same pressure in separate cylinders with movable pistons of radii \(r_A\) and \(r_B\) respectively. On supplying an equal amount of heat to both the cylinders, their pressures remain constant and their pistons are displaced by 16 cm and 9 cm respectively. If the change in their internal energies is the same, then the ratio \(r_A / r_B\) is:

Photosynthesis in Higher Plants
Processes Of Photosynthesis in Higher Plants:
Photosynthesis in higher plants involves the following processes:
- Light Reaction
- Dark Reaction
Light Reaction:
- This phenomenon occurs in the presence of light.
- The pigment absorbs light and produces energy in the form of ATP.
- The process involves- absorption of light, water splitting, the release of oxygen, and formation of ATP and NADPH.
Dark Reaction:
This process occurs in the absence of light in the stroma of the chloroplasts. The following cycles are involved in the process:
- Calvin Cycle (C3 Cycle)
- C4 Cycle (Hatch and Slack Pathway)
