Main difference between animal cell and plant cell is in

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

  1. Mode of Nutrition

  2. Growth

  3. Movement

  4. Respiration

Show answer
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

Show answer
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

Show answer
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.

Find the odd one out:

  1. Plastid

  2. Mitochondria

  3. Endoplasmic reticulum

  4. Vacuoles

Show answer
Correct Option: A
Explanation:

Plastids are the storage molecules found in plants cells. These are three type of plastids viz. chloroplast(storing photosynthetic pigments), leucoplast(storing food materials). Chromoplast(storing pigment molecules other then photosynthetic pigment).

Which one of the following lists the structures which are present both in animal and plant 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, Chromosomes, Cytoplasm, Chloroplasts

  2. Cell membrane, Chromosomes, Cytoplasm, Mitochondrion

  3. Cell membrane, Chloroplast, Chromosomes, Cytoplasm

  4. Cytoplasm, Mitochondrion, Cell wall, Chromosomes

Show answer
Correct Option: B
Explanation:

The plant and animal cells are eukaryotic and contain well developed cellular organelles. The cell membrane, cytoplasm, chromosomes, and mitochondria are the structures which are present in both the plant and the animal cells. The cell wall and chloroplast are present only in the plant cell. 

Thus, the correct answer is option B. 

A plant cell and an animal cell are dissimilar as plant cell possess
I. A nucleus   II. A cell wall   III. A cell membrane  IV. Cytoplasm  V. Chloroplasts.

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

  1. II and V only

  2. II and III only

  3. I, III and IV only

  4. II, III and IV only

Show answer
Correct Option: A
Explanation:

Plant cells have cell wall. The cell wall is a non-living layer secreted by protoplasm of the cell that forms a protective covering around the living plasma membrane. It provides rigidity to the plant. Animals lack cell wall hence they show locomotion.

Chloroplast is present in plant cells and is involved in photosynthesis. Hence plants are said to be autotrophs. Animal cells lack chloroplast and are heterotrophs. 
Thus the correct answer is option A.

Cell wall is absent in the cell of __________

  1. Mushroom

  2. Moss

  3. Fern

  4. Mosquito

Show answer
Correct Option: D
Explanation:

The cell wall are present in the cells of plants, fungal and other organisms. The animal cells lack the cell wall. The mosquitoes have cells with the cell membrane and there is no cell wall. 

Thus, the correct answer is 'Mosquito'.

A plant cell differs from an animal cell due to the presence of ____________.

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

  1. Cell membrane

  2. Endoplasmic reticulum

  3. Plasma membrane

  4. Cell wall

Show answer
Correct Option: D
Explanation:

A difference between plant cells and animal cells is that most animal cells are round whereas most plant cells are rectangular. Plant cells have a rigid cell wall that surrounds the cell membrane. Animal cells do not have a cell wall.

So, D is the correct option. 

Which organelle is absent in animal cell?

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

  1. Chloroplasts

  2. Golgi apparatus

  3. E.R.

  4. Lysosomes

Show answer
Correct Option: A
Explanation:
  • The chloroplast is a plastid which contains chlorophyll (green pigment) within the thylakoid membranes of the organelle.
  • This organelle is present in the green parts of plants where photosynthesis takes place.
  • The chlorophyll pigment captures the sunlight and converts it into chemical energy and thus, helps in the process of photosynthesis.
  • This organelle is absent in an animal cell.
  • So, the correct answer is 'Chloroplasts'.

Animal cells do not posses :

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

  1. Plasmodesmata

  2. Centriole

  3. 80S ribosomes

  4. All the above

Show answer
Correct Option: A
Explanation:

Plasmodesmata are the channels through the cell wall. They are found only in plant cells. They contain cytosol or cytoplasm which allows a to and fro movement of nutrients and other materials between cells. They help to organize cells in different tissues.

Centrioles are found only in animal cells. Then carry out cell division.
The 80S ribosome is found in both animals and plant cell as it is characteristic of the eukaryotic cell.
Option A is correct.
