Question 1
1 / -0

Which of the following is present in bacterial cells, but absent in animal cells?

A
Cytoplasm

B
Plasma membrane

C
Cell membrane

D
Cell wall

Solution

Cell wall and cell membrane are both present in bacterial cells, whereas animal cells contain only cell membrane.
Question 2
1 / -0

The dark spot-like structure inside the nucleus of a cell that helps in making ribosomes is called

A
nucleoplasm

B
nucleoid

C
nucleoside

D
nucleolus

Solution

The dark spot-like structure that helps in making ribosomes is called nucleolus and it is present in the nucleus.
Question 3
1 / -0

Which of the following is not a component of cytoplasm?

A
Mitochondria

B
Ribosome

C
Nucleus

D
Cytosol

Solution

Nucleus is not a part of cytoplasm. Cytoplasm includes only cytosol and cell organelles.
Question 4
1 / -0

Which of the following cells are amoeboid in shape?

A
Red blood cells

B
White blood cells

C
Nerve cells

D
Guard cells

Solution

White blood cells are amoeboid in shape. They can squeeze out through capillary walls.
Question 5
1 / -0

Which of the following statements is false about cell membrane?

A
It is semi-permeable.

B
It is flexible.

C
It is non-living.

D
It is made of lipoproteins.

Solution

Cell membrane is the outermost thin, flexible, living membrane of a cell. It possesses fine pores. The principal components of the plasma membrane are lipids (phospholipids and cholesterol), proteins, and carbohydrate groups that are attached to some of the lipids and proteins.
Question 6
1 / -0

Which of the following is spindle shaped?

A
Plasma membrane

B
Smooth muscle

C
RBC

D
Neuron

Solution

Smooth muscle, which is involuntary, is spindle shaped.
Question 7
1 / -0

Which of the following serve as food for the cell?

A
Granules

B
Golgi bodies

C
Ribosomes

D
Mitochondria

Solution

Starch (in plant cells), glycogen (in animal cells) and fat containing granules serve as food for the cell.
Question 8
1 / -0

Choose the correct order in terms of increasing organisation.

A
Cell Tissue Organ

B
Organ Tissue Cell

C
Tissue Cell Organ

D
Cell Organ Tissue

Solution

Correct order in terms of increasing organisation is: Cell Tissue Organ
Question 9
1 / -0

Which of the following statements is false about the discovery of cell?

A
Cell was discovered by Mendel.

B
Cell was discovered in 1665.

C
Cell was discovered under a simple magnifying device.

D
The discovered cells were dead cells.

Solution

Cell was discovered by Robert Hooke in 1665 under a simple magnifying device from a thin slice of cork. These were dead cells.
Question 10
1 / -0

A student is provided with four different slides of fungal, bacterial, plant and animal cells, respectively. He is asked to identify the cells in which nuclear materials are present without a nuclear membrane, which he does correctly. Which cells do you think he identified?

A
Fungal cells

B
Bacterial cells

C
Plant cells

D
Animal cells

Solution

In prokaryotes like bacteria, nuclear material is not enclosed by a nuclear membrane.
Question 11
1 / -0

What advantage does amoeba derive by changing its shape?

A
Facilitation in jumping

B
Ease in capturing food

C
Improvement in its structure

D
Strengthening its body

Solution

Amoeba can change its position as it facilitates movement and helps in capturing food.
Question 12
1 / -0

The thread-like structures present in the nucleus are collectively called

A
nucleolus

B
genes

C
chromatin

D
ribosomes

Solution

The thread-like structures present in the nucleus are collectively called chromatin.During cell division, chromatin fibres become thick ribbon-like structure known as chromosomes. The chromatin fibres remain twisted or form a network in the nucleoplasm.
Question 13
1 / -0

What is the function of cell wall in plants?

A
Provides shape and flexibility to the cells

B
Provides green colour to the leaves

C
Provides brown colour to the bark

D
Provides shape and rigidity to the cell

Solution

Cell wall provides shape and rigidity to the cell.
Question 14
1 / -0

Why do scientists use stain to colour a part of the cell?

A
To study detailed structure of the cell

B
To study functions of the cell

C
To make the cell alive

D
To study shape of the cell

Solution

Scientists use stains to study detailed structure of the cell.
Question 15
1 / -0

Which of the following cells has a single and big central vacuole?

A
Bacterial cell

B
Fungal cell

C
Plant cell

D
Animal cell

Solution

A plant cell has a single and big central vacuole. Vacuole in an animal cell is comparatively smaller in size.
