Question 1
1 / -0

Larger sized organisms usually have

A
Large sized cells

B
More non-cellular material

C
Higher number of cells

D
More cellular excretions
Question 2
1 / -0

Different cells have different sizes. Arrange the following cells in ascending order of their size and select the correct option:
(i) Mycoplasma (ii) Ostrich egg
(iii) Human RBCs (iv) Bacteria

A
(i) $$\rightarrow$$ (iv) $$\rightarrow$$ (iii) $$\rightarrow$$ (ii)

B
(i) $$\rightarrow$$ (iii) $$\rightarrow$$ (iv) $$\rightarrow$$ (ii)

C
(ii) $$\rightarrow$$ (i) $$\rightarrow$$ (iii) $$\rightarrow$$ (iv)

D
(ii) $$\rightarrow$$ (ii) $$\rightarrow$$ (i) $$\rightarrow$$ (iv)
Solution
- The smallest cell is Mycoplasma (0.1-0.5$$\mu m$$).
- The bacterial cell measures 3-5$$\mu m$$ in length.
- Erythrocytes (RBCs) are 6-8$$\mu m$$ in diameter.
- The largest cell is the egg of an ostrich.
So, the correct answer is option "(i) $$\rightarrow$$ (iv) $$\rightarrow$$ (iii) $$\rightarrow$$ (ii)".
Question 3
1 / -0

The ______ is the basic structural and functional unit of life.

A
Tissue

B
Organ

C
Cell

D
Organelle

Solution

The cell is the basic structural and functional unit of life. Whether it is a complex organism like humans, animals or plants or simple organisms like the bacteria, they are all made of cells. So, the cell forms the most basic level of organization of organisms.
Question 4
1 / -0

Plant cells differ from animal cells in having __________.

A
Cell wall

B
Plastids

C
A large central vacuole

D
All of these

Solution

A plant cell has a rigid cell wall on the outside. It has plastids and a centrally located large vacuole. Animal cells do not have cell walls and plastids. The vacuoles are smaller and not centrally placed.
Hence, the correct option is D.
Question 5
1 / -0

Identify the parts labelled as A, B, C and D in the given ultrastructure of a plant cell and select the correct option.

A
A- Plasma membrane; B- Chloroplast; C-Mitochondrion; D- Vacuole

B
A- Plasma membrane; B- Mitochondrion; C-Chloroplast; D- RER

C
A- Cell wall; B- Mitochondrion; C-Chloroplast; D- RER

D
A- Cell wall; B- Chloroplast; C-Mitochondrion; D- Golgi complex
Solution
Plant cells have certain distinguishing features, including chloroplasts(B), cell walls (outermost covering), and intracellular vacuoles (D).
Inner to cell wall is the plasma membrane (A).
Mitochondria (C) is a round to oval-shaped organelle found in the cells of almost all eukaryotic organisms.
So, the correct answer is option A.
Question 6
1 / -0

Bacteria is a

A
Prokaryotic Cell

B
Eukaryotic Cell

C
Both Prokaryotic and Eukaryotic cell

D
Partially eukaryotic
Solution
Correct option: A

Explanation:
Bacteria is a single celled prokaryotic organism. Their cell structure is simpler than eukaryotic cells without nucleus or membrane bound organelles.
Bacteria are found in every habitat on Earth: soil, rock, oceans and even arctic snow. And these reproduce by binary fission.
Thus, Option A is correct.
Question 7
1 / -0

The organelles that are present in both plant and animal cells include ............. .

A
Cell membrane

B
Chloroplast

C
Cell wall

D
None of the above

Solution

The cell membrane is one component that is present in all the cells. Since it is present in all the cells it is considered to be one of the basic components of any Eukaryotic cell.
Question 8
1 / -0

From the following, identify which is the living matter of the cell?

A
Chloroplast

B
Endoplasmic reticulum

C
Protoplasm

D
Mitochondria
Solution
- The living matter of cell is protoplasm which is the colorless material. It comprises of all the components within a cell.
So the correct answer is 'protoplasm'.
Question 9
1 / -0

Which of the following statements is correct

A
The nuclear membrane is present in Eukaryotic cells

B
The nuclear membrane is present in Prokaryotic cells

C
The nuclear membrane is present in both Prokaryotic and Eukaryotic cells

D
The nuclear membrane is absent in the Eukaryotic cells

Solution

The Eukaryotic cells have a true nucleus i.e.nucleus is covered and protected by a nuclear membrane. Presence of Nuclear membrane or the nucleus is a unique feature of the Eukaryotic cells.
Prokaryotes lack nuclear membrane.
Hence the correct option is A.
Question 10
1 / -0

Auxospores are formed in the life cycle of diatoms these structure are ________________.

A
Vegetuative cells with ploidy level N

B
Asexual spores with ploidy level N

C
Statosspores with 2N ploidy Level

D
Sexual spores with ploidy level $$2N$$

Solution

Auxospores are formed by diatoms at an important stage of their life cycle. They are specialized cells which help the diatoms in regaining their normal size. After cell division in diatoms, each daughter cell inherits one of the two valves and hence results in reduction of size of the diatom, to retain the size diatoms produce auxospores and hence they are vegetative.
So, the correct option is, 'Vegetuative cells with ploidy level N'.
