Which of the following structures is usually present only in animal cells?

  1. Vacuoles

  2. Cell wall

  3. Nucleus

  4. Centrioles
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Vacuoles are storage bubbles found in animal and plant cells, but bigger in plant cells. These are used for storage of food or water. 
The cell wall is a protective outer covering of the cell. It is mostly present in plant cells. It supports the contents of the cell and protects from pathogen attack and wear and tear. It is made of cellulose, lignin. 
The nucleus of the cell contains a majority of the cell's genetic material, i.e., DNA in the form of DNA-protein complex, called as chromatin. It is present in both animal and plant cells. 
Animal cells contain centrioles, cylindrical organelles that help in cell division and absent in plant cells. Thus, the correct answer is option D.

The plant cells are more rigid than the animal cell due to

  1. Cell wall

  2. Vacuoles

  3. Plastids

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

The cell wall of the plant cell is very rigid, tough and thick covering. It supports the contents of the cell and is made of cellulose and lignin. 
Vacuoles are storage bubbles found mostly in plant cells. They occupy most of the portion of plant cells. These are used for storage of food or water. Osmotic pressure and turgidity is maintained by vacuoles. Whereas animal cells lack a cell wall and large sized vacuole.

Is there any difference between animal and plant vacuoles?

  1. In animal cell, small vacuoles are present, but in mature plant cell, a large central vacuole occupies the centre of the cell.

  2. In animal cell vacuoles are small, but in plant cell vacuoles are large.

  3. Both A and B.

  4. None of the above.

C Correct answer
Explanation

Vacuoles are storage bubbles which are present in both, animal and plant cells. These are used for storage of food or water. Osmotic pressure and turgidity are maintained by vacuoles. Plant cell vacuoles are bigger than animal cells. It occupies most of the part of the plant cell and generally present in the center.

Consider the following statements


A. Centrioles are present in almost all animals cells.
B. Ribosomes are the site of protein synthesis.
C. The middle lamella is the layer made up of calcium carbonate which holds the neighboring cells together.
D. In animal cells, steroidal hormones are synthesized by smooth endoplasmic reticulum.
The true statements are 

  1. B and D

  2. A and D

  3. B and C

  4. A, B and D
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The centrioles are the organelles present in the animal cells which are required for the formation of spindle fibres during cell division. 

The ribosomes are the cell organelles which are involved in the process of translation or the formation of the proteins from the mRNA. 
The middle lamella is made up of pectin which holds the two adjacent cells together. 
In the animal cells, the steroid and lipid hormones are synthesized in the smooth ER.
Thus, the correct answer is option D.

Plant and animal cell divisions differ in 

  1. Cell plate

  2. Prophase

  3. Metaphase

  4. Telophase
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The plant and animals are the eukaryotic cells which divide by mitotic cell division. The various stages of the mitosis are prophase, metaphase, anaphase and telophase, which are same for all the eukaryotic cells. During telophase, there is the formation of the cell plate in case of plant cells which allows the separation of the two daughter cells. In the case of animal cells, there is pinching of the cell membrane to separate the cells. Thus, the correct answer is option A.

In a plant cell, cytokinesis occurs by

  1. Separation of the cytoplasm from the periphery to central region

  2. Separation of the cytoplasm from cell centre to its periphery

  3. Separation of the cytoplasm throughout the equatorial plane simultaneously

  4. Furrowing of cytoplasm from two sides at right angles to the plane of spindle pole
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

In plant cells, cytokinesis involves the formation of a cell plate that starts at the center of the cell and grows outward toward the periphery, eventually fusing with the existing cell wall.

Which organelle would you expect to find in a plant cell but not an animal cell?

  1. Smooth endoplasmic reticulum

  2. Mitochondria

  3. Ribosome

  4. Chloroplast
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Plant cells contain Chloroplast to carry out function of photosynthesis to create food for it. Animal cells depend on other sources for food as they lack Chloroplasts.

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
Reveal answer Fill a bubble to check yourself
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.
