What is the difference in the vacuoles of both plant and animal cells?

  1. Animal cells- contain only waste, Plant cells- contain only water

  2. Animal cells- small vacuoles, Plant cells- vacuoles make up 90% of cell

  3. Animal cells- vacuoles make up 90% of cell, Plant cells- small vacuoles

  4. Animal cells- contain only water, Plant cells- contain only waste

  5. Vacuoles are the same in both, Plant and animal cells

B Correct answer
Explanation

Explanation: In plant cells, central vacuole is larger than all of the other organelles, which makes up to 90% of cell. In animal cells, small vacuoles are present.

Plants differ from animals as the plants have_______

  1. An endoplasmic reticulum

  2. A central vacuole

  3. Golgi complexes

  4. Vesicles
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

In plant cells, central vacuole is larger than all of the other organelles. The central vacuole is a membrane-bound organelle containing water and other enzymes that function during the life of the plant. Structurally, the central vacuole is surrounded by a phospholipid bilayer.

Which of the following characters distinguishes plant cells from animal cells?

  1. Cell wall

  2. Glyoxysomes

  3. Plastids

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Plastids are present in plant cells, whereas, an animal cell these are usually absent. It helps to trap sunlight for photosynthesis.
Glyoxysomes are present in the plant cell but are absent in an animal cell. It helps in the storage of fats in germinating cells.
The cell wall is present outside of plant cell and absent in an animal cell. It gives rigidity in a plant cell.
So, the correct answer is option D.

Plant cells differ from animal cells in having

  1. Mitochondria

  2. Cell wall

  3. Ribosomes

  4. Golgi bodies
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Plant cell and animal cells are mostly similar because both are eukaryotic cells but the only difference is that plant cell contains cell walls, vacuoles, and chloroplasts.

Hence, the correct answer is 'cell wall'.

The pigment, melanin in animals protects them from UV radiations and is functionally equivalent pigment in plants is 

  1. Melanin only

  2. Carotenes

  3. Anthocyanin

  4. Both B and C
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Anthocyanin is a red colour, water-soluble pigment found in plant cell vacuoles and cell walls. It is not involved in the process of photosynthesis but serves to attract insects and animals to flowers and fruits. It also serves to protect plant cell from high energy radiations like melanin pigment in animals.

Different cells have different sizes. Arrange the following cells in an ascending order of their size and select the correct option.
(i) Mycoplasma (ii) Ostrich egg (iii) Human RBCs (iv) Bacteria.
  1. $(i)\rightarrow (iv)\rightarrow (iii) \rightarrow (ii)$
  2. $(ii)\rightarrow (iii)\rightarrow (i) \rightarrow (ii)$
  3. $(ii)\rightarrow (i)\rightarrow (iii) \rightarrow (iv)$
  4. $(iii)\rightarrow (ii)\rightarrow (i) \rightarrow (iv)$
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The size order is: Mycoplasma (smallest, ~0.1-0.3 micrometers) < Bacteria (~1-2 micrometers) < Human RBCs (~7-8 micrometers) < Ostrich egg (largest, macroscopic).

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • The smallest cell is Mycoplasma (0.1-0.5$\mu m$). 
  • Bacterial cell measures 3-5$\mu m$ in length. 
  • Erythrocytes are 6-8$\mu m$ in diameter. 
  • The larges cell is the egg of Ostrich.
