Why Is Photosynthesis Important in Nature?

Which tissues and cells are mainly concerned with photosynthesis?

Why green leaves are thin and broad?

What is the importance of photosynthesis in the life of the following:

Non-green plants

What is the importance of photosynthesis in the life of the following:

Green plants

A potted plant was taken in order to prove a factor necessary for photosynthesis. The potted plant was kept in the dark for 24 hours. One of the leaves was covered with black paper in the centre. The potted plant was then placed in sunlight for a few hours.

Write a balanced chemical equation to represent the process of photosynthesis.

A potted plant was taken in order to prove a factor necessary for photosynthesis. The potted plant was kept in the dark for 24 hours. One of the leaves was covered with black paper in the centre. The potted plant was then placed in sunlight for a few hours.

During the starch test, why was the leaf

(1) boiled in water

(2) boiled in methylated spirit

A potted plant was taken in order to prove a factor necessary for photosynthesis. The potted plant was kept in the dark for 24 hours. One of the leaves was covered with black paper in the centre. The potted plant was then placed in sunlight for a few hours.

Why was the plant placed in the dark before beginning the experiment?

A potted plant was taken in order to prove a factor necessary for photosynthesis. The potted plant was kept in the dark for 24 hours. One of the leaves was covered with black paper in the centre. The potted plant was then placed in sunlight for a few hours.

What aspect of photosynthesis was being tested?

Name the membrane that connects thylakoid of one granum With the other granum.

Where are the chlorophyll pigments present in a cell?

Name the molecules which are called assimilatory power? Why are they called so?

How is the rate of photosynthesis affected when a green plant gets the green light?

Name the following:

In-plant cells, carbohydrates are stored in which form.

• glucose

• starch

• glycogen

Name the following:
The immediate product of photosynthesis.

Name the following:
A high energy-reduced compound formed in the light reaction and enter into the dark reaction.

Name the following:
Light in which the maximum rate of photosynthesis takes place.

Name the following:
The site of light reaction in the cell of a leaf.

Name the following:
Source of oxygen given out in photosynthesis.

Name the following:
The principal site in a green leaf for photosynthesis.

Name the following:
The green colouring matter of the plants.

Name the following:
The chemical substance used to test the presence of starch in the cell of a leaf.

Name the following:
The process by which plants produce their food.

Give technical term:
Name only one plant, you are familiar with which has no chlorophyll.

Give technical term:
Which process is the ultimate source of energy for all living organisms?

Give technical term:
The main reaction which means the breaking up of water molecules through light.

Give technical term:
Organisms which cannot prepare their own food by photosynthesis.

Give technical term:
In photosynthesis radiant energy is converted into which from?

Give technical term:
The form of energy is converted into chemical energy during photosynthesis.

Give technical term:
Name the structure where photophosphorylation takes place.

Give technical term:
Name the experiment to demonstrate the importance of light for photosynthesis.

Give technical term:
The part of the chloroplast where the dark reaction of photosynthesis takes place.

Give technical term:
What does NADP stand for?

Give technical term:
What does ATP abbreviate for?

Give technical term:
Name the tissue that transports manufactured starch from the leaves to all parts of the plant.

Give technical term:
Name the process which is responsible for the conversion of solar energy to chemical energy that is essential to sustain life on this earth?

Respiration is said to be the reversal of photosynthesis.

ATP is needed for the dark reaction.

Chloroplasts are called energy converters.

Chlorophyll is necessary for photosynthesis.

Photosynthesis is considered as a process supporting all life on earth.
