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

bio-chemistry caskets of life animal cells vs plant cells comparing plant and animal cells comparison between animal and plant cell

  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

Show answer
Correct Option: B
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_______

bio-chemistry caskets of life animal cells vs plant cells comparing plant and animal cells comparison between animal and plant cell

  1. An endoplasmic reticulum

  2. A central vacuole

  3. Golgi complexes

  4. Vesicles

Show answer
Correct Option: B
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.

What regulates what enters and leaves the cell and provides protection and support in Animal cells?

  1. Golgi Apparatus

  2. Vacuole

  3. Cell Wall

  4. Cell Membrane

Show answer
Correct Option: D
Explanation:

Cell Membrane regulates what enters and leaves the cell and provides protection and support in Animal cells.

Unlike plant cells, animal cells have________

  1. No vacuoles

  2. 1 vacuole

  3. 2 vacuoles

  4. Many vacuoles

Show answer
Correct Option: D
Explanation:

Explanation: Unlike a large single vacuole in the centre of plant cells, animal cells can have many vacuoles.

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

bio-chemistry caskets of life animal cells vs plant cells comparing plant and animal cells comparison between animal and plant cell

  1. Cell wall

  2. Glyoxysomes

  3. Plastids

  4. All of the above

Show answer
Correct Option: D
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

Show answer
Correct Option: B
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 

bio-chemistry caskets of life animal cells vs plant cells comparing plant and animal cells comparison between animal and plant cell

  1. Melanin only

  2. Carotenes

  3. Anthocyanin

  4. Both B and C

Show answer
Correct Option: C
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.

  2. (i) $\rightarrow$ (iii) $\rightarrow$ (iv) $\rightarrow$ (ii)

  3. (ii) $\rightarrow$ (i) $\rightarrow$ (iii) $\rightarrow$ (iv)

  4. (ii) $\rightarrow$ (ii) $\rightarrow$ (i) $\rightarrow$ (iv)

Show answer
Correct Option: A
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.

Mice and elephant have

botany caskets of life the cell structure multicellular organisms number and shape of cells

  1. The same cell number

  2. Different cell numbers

  3. The same cell number but different cell sizes

  4. The same cell number and same cell sizes

Show answer
Correct Option: B
Explanation:

The body size of the organism is directly related to the cell number, not the cell size. The bigger the body, the more will the number of cells.
