What will happen to the rate of photosynthesis in a plant under the cloudy day in morning but bright sunshine in the afternoon?

• The rate of photosynthesis decreases in cloudy day in morning but increases in bright sunshine in the afternoon.

• The rate of photosynthesis decreases in the area where there is no rainfall

  for a considerable time.

What will happen to the rate of photosynthesis in a plant under the no rainfall in the area for a considerable time.?

• The rate of photosynthesis decreases in the area where there is no rainfall for a considerable time.

• The rate of photosynthesis decreases when dust gathers on the leaves.

What will happen to the rate of photosynthesis in a plant under the gathering of dust on the leaves?

• The rate of photosynthesis decreases when dust gathers on the leaves.

• The rate of photosynthesis decreases in the area where there is no rainfall

  for a considerable time.

What is photosynthesis?

• The process by which green plants make their food in the presence of sunlight and chlorophyll with the help of inorganic substances like carbon dioxide and water, is called photosynthesis.

• Trypsin is a pancreatic enzyme which is secreted by pancreas. It digests the

  proteins.

Explain the mechanism of photosynthesis. What is the first statement of this audio clip?

• The process of photosynthesis takes place in the green leaves of a plant.

• Plants need carbon dioxide and water for the process of photosynthesis.

• Plants take carbon dioxide from the air.

• Carbon dioxide enters the leaves

  through tiny pores present on the leaves’ surface called stomata.

Explain the mechanism of photosynthesis. What is the second statement of this audio clip?

• The process of photosynthesis takes place in the green leaves of a plant.

• Plants need carbon dioxide and water for the process of photosynthesis.

• Plants take carbon dioxide from the air.

• Carbon dioxide enters the leaves

  through tiny pores present on the leaves’ surface called stomata.

Explain the mechanism of photosynthesis. What is the third statement of this audio clip?

• The process of photosynthesis takes place in the green leaves of a plant.

• Plants need carbon dioxide and water for the process of photosynthesis.

• Plants take carbon dioxide from the air.

• Carbon dioxide enters the leaves

  through tiny pores present on the leaves’ surface called stomata.

Explain the mechanism of photosynthesis. What is the fourth statement of this audio clip?

• The process of photosynthesis takes place in the green leaves of a plant.

• Plants need carbon dioxide and water for the process of photosynthesis.

• Plants take carbon dioxide from the air.

• Carbon dioxide enters the leaves

  through tiny pores present on the leaves’ surface called stomata.

Explain the mechanism of photosynthesis. What is the fifth statement of this audio clip?

• Plants take

  water from the soil through their roots by the process of osmosis.

• The xylem

  vessels then transport the water to the leaves where it reaches the

  chloroplast containing cells and is utilized in photosynthesis.

• The process of

  photosynthesis takes place in the presence of sunlight.

• The sunlight provides

  energy required to carry out the chemical reactions involved in the preparation of food.

• This sunlight energy is absorbed by the green pigment

  called chlorophyll.
