Questions Related to comparing plant and animal cells

Plant cells differ from animal cells in having __________.

  1. cell wall

  2. plastids

  3. a large central vacoule

  4. all of these


Correct Option: D
Explanation:

A plant cell has rigid wall on the outside. It has plastids and a centrally located large vacuole. All of these are absent in an animal cell.

The shape of an animal and plant cell is primarily maintained respectively by the following

  1. Exoskeleton, endoskeleton

  2. Cell membrane, cell wall

  3. Cytoskeleton, cell wall

  4. Endoskeleton, cytoskeleton


Correct Option: A

Which of the following is found in any plant cell but not in animal cell?

  1. Cell wall

  2. Mitochondria

  3. Cell membrane

  4. Nucleus


Correct Option: A
Explanation:
  • The cell wall is a rigid layer of polysaccharides lying outside the plasma membrane of the cells of plants, fungi, and bacteria. In the algae and higher plants, it consists mainly of cellulose.
  • A major function of the cell wall is to give the cell strength and structure and to filter molecules that pass in and out of the cell.
  • It is absent in the animal cell.
Hence cell wall is found in any plant cell but not in the animal cell.
So, the correct answer is 'Cell wall'.

The term 'sarcode' for protoplasm was coined by

  1. Dujardin

  2. Hugo Von Mohl

  3. Fontana

  4. F. Meischer


Correct Option: A
Explanation:
Leeuwenhoek was the first to see free living cells. He observed bacteria, protozoa, red blood cells, sperms etc. under his microscope. In 1809, Lamarck concluded that all living beings are formed of cells. Living substance was first observed by Corti in 1772 and was named sarcode by Dujardin in 1835.
So, the correct answer is 'Dujardin'.

'Protoplasm is the physical basis of life' was suggested by

  1. Purkinje

  2. Huxley

  3. Sidney Fox

  4. Hugo Von Mohl


Correct Option: B
Explanation:
Protoplasm or living matter is a polyphasic crystallo-colloidal complex that possesses all the properties of life and is found inside living cells. It was called as sarcode by Dujardin in 1835. The term protoplasm was coined by Purkinje in 1839. Huxley in 1868, has called it as physical basis of life because all the properties of life reside in the protoplasm.
So, the correct answer is 'Huxley'.

Cell organelle which differentiates plant cell from animal cell is

  1. Cell membrane

  2. Plastids

  3. Nucleolus

  4. Vacuoles


Correct Option: B
Explanation:

The plastid is the most important double-membrane organelle in the cells of plants and algae and absent in animal cells. Plastids are the site of manufacture and storage of important chemical compounds used by the cell. Plastids are cell organelles found in all plant cells and in euglenoids. They bear some specific pigments which impart specific colours to the plants.

The animal and plant cells differ in their

  1. Movement

  2. Growth

  3. Nutrition

  4. Respiration


Correct Option: C
Explanation:
Plant and animal cells both are eukaryotic cell but, they possess certain distinguishing characters like plants are autotrophic while animals are heterotrophic in general. Plants are able to trap light energy and converts them into chemical energy, while animals depend on plants for the food.

Main difference between animal cell and plant cell is in

  1. Mode of Nutrition

  2. Growth

  3. Movement

  4. Respiration


Correct Option: A
Explanation:

  • The animal cell is heterotrophic, i.e., cannot synthesize their own food. They have to obtain food from other organisms. 
  • Plant cells possess chloroplast using which they can synthesize their own food material, i.e., they are autotrophic. Therefore, their mode of nutrition differs. 

Thus, the correct answer is option A.

Animal cells do not have 

  1. Cell wall

  2. Chloroplast

  3. Plastids

  4. All of the above


Correct Option: D
Explanation:

Animal cells do not have a cell wall. Animal cells do not have chloroplasts. In animal cells, energy is produced from food (glucose) via the process of cellular respiration. The plastid is a major double-membrane organelle found, among others in the cells of plants and algae. These plastids are not present in animal cells.

Which of the following combinations are present in plant cell but not in animal cell?

  1. Cell wall and plastid

  2. Cell wall and cell membrane

  3. Plastid and nucleus

  4. Cell membrane and cytoplasm


Correct Option: A
Explanation:
Plant and animal cells are both eukaryotic cell but have several differences such as animal cells are round and do not have a cell wall or chloroplasts but plant cells are rectangular and possess cell wall and plastids.
