Answer 1

1. The overall reaction for photosynthesis is

6CO2 + 6H2O + Sunlight --------> C2H12O6 + 6O2

Every organism needs energy. Photosynthesis is the process by which plants convert light energy into chemical energy. During photosynthesis, plants using sunlight converts carbon dioxide and water into glucose and oxygen. Photosynthesis occurs in the chloroplast

2. Sunlight.

For photosynthesis, in addition to carbon dioxide and water, plants need light energy. Using light from the sun, they convert carbon dioxide and water into glucose and oxygen. Glucose provides energy to the plants.

3. Chlorophyll

Chlorophyll is the principal pigment of plants. Chlorophyll is found in the chloroplast of the plants. Chlorophyll absorbs light from the sun. Chlorophyll is a natural pigment with green colour. It gives colour to plants.

4. (a) Blue region and (c) red region

Chlorophyll absorbs light of blue and red regions of the visible spectrum. Blue and red have high energy and the correct amount of wavelength of light that is required for photosynthesis. Blue has the highest frequency and red has the highest wavelength.  so chlorophyll absorbs blue and red most. Chlorophyll absorbs the green color of light least, but it reflects the green color

5. Thylakoids.

Chloroplasts contain sacklike photosynthetic membranes called thylakoids. The chlorophyll pigments are contained in thylakoids of chloroplast. Stacks of thylakoids are called grana. Light-dependent reactions take place in thylakoids of chloroplast

6. Stroma

The fluid surrounding the thylakoid membranes in the chloroplasts is called the stroma. stroma is a colorless fluid that surrounds grana in the chloroplast
