Oral Questions
1. What kind of energy transformation takes place during photosynthesis ?
2. What is the mode of nutrition in green plants?
3. Name the green pigment present in green leaves which takes part in photosynthe
4. Write the mode of nutrition in humans.
5. Which light is more effective in photosynthesis?​

Answer 1

Answer:

1) Radiant energy (heat energy) is converted to chemical energy.

2) Autotrophic

3) Chlorophyll

4) Heterotrophic

5)Red and blue wavelength are more effective.

Answer 2

Answer:

1) DURING PHOTOSYNTHESIS THE LIGHT ENERGY FROM SUN IS CONVERTED INTO CHEMICAL ENERGY(FOOD). The energy transformation that is taking place in the photosynthesis process is the conversion of "light energy" into "chemical energy". This transformation drives the photosynthesis process and food production.

2) Green plants have an autotrophic mode of nutrition.

3) Chlorophyll is the green pigment present in green leaves which takes part in photosynthesis.

4) Mode of nutrition in human beings is heterotrophic.

5) Certain red and blue wavelengths of light are the most effective in photosynthesis because they have exactly the right amount of energy to energize, or excite, chlorophyll electrons and boost them out of their orbits to a higher energy level.
