Experimental Study

Q.

In this experiment, how does KOH affect the process of photosynthesis in the plant kept in bell jar ?

1. Increases water intake and O₂ production.

2. Inhibits CO₂ intake by plant.

3. Stops the glucose/ starch production in leaves.

4. Both B and C.

Q.

The figure given below represents an experimental setup to study a physiological process in plants.

1. Name the physiological process being studied.
2. Explain the process.
3. What is the aim of the experiment?
4. Give a well-balanced equation to represent the process.

Q. Why cell membrane is bilayer?

Q. State one similarity and two differences between cell wall and cell membrane.

Q.

The cell wall is mainly composed of cellulose. So where is this cellulose manufactured in the cell?

Q.

What can be concluded from the experiment shown below?

1. Oxygen is evolved during photosynthesis

2. Carbon dioxide is evolved during photosynthesis.

3. Sunlight has no role in photosynthesis.

4. Water is not required for photosynthesis to take place.

Q.

Statement 1: Light is not required for dark reaction.

Statement 2: Dark reaction takes place in the grana region of chloroplast.

1. Statement 1 is true and statement 2 is false

2. Statement 1 is false and statement 2 is true

3. Both the statements are true

4. Both the statements are false

Q.

In addition to the cell membrane, there is an outer thick layer in plant cells which is known as ___.

1. nuclear membrane

2. tonoplast

3. cell wall

4. plasma membrane

Q.

Correct statement of dark reaction is

1. it occurs in the presence of light only.

2. it occurs in absence of light only

3. it is independent of light

4. All of these

Q.

If we keep different parts of plant separate from each other such as roots, stem, leaves, flower, fruit which part will turn lime water milky ?

Q. Animal cells have as the outermost cover while plants have in addition to it.

1. cell wall
2. cell membrane
3. shell
4. cytoplasm
