Find the odd one out:

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

  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?

  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?

  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 :

  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.

In plant and animal cells, chromatids or chromatin are made up of:

  1. Only DNA

  2. DNA,RNA and Hisone

  3. DNA, RNA, Protein and some fat bodies

  4. DNA, RNA, Histone and non histones

Show answer
Correct Option: A

The interior of a cow-dung pile kept for a few days is quite warm. This is mostly because: 

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

  1. Cellulose present in the dung is a good insulator.

  2. Bacterial metabolism inside the dung releases heat.

  3. Undigested material releases heat due to oxidation by air.

  4. Dung is dark and absorbs a lot of heat.

Show answer
Correct Option: B
Explanation:

At the later stages of decomposition of cowdung, mesophilic micro-organisms decompose the dung, generating heat from exothermic( process which produces heat) processes; such heat generation is associated with the well known phenomenon of the elevated temperature of composting.

How plant cells are different from animal cell?

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

  1. Plant cells have cell wall, animal cells do not have cell wall.

  2. Plant cells have chloroplast, animal cells not do not have chloroplast.

  3. Both A and B.

  4. None of these.

Show answer
Correct Option: C
Explanation:

  • Plant cells have a cell wall, plastids, and a large central vacuole, which are not found in animal cells. The cell wall is a rigid covering that protects the cell, provides structural support and gives shape to the cell. 
  • The chloroplasts, found in plant cells, contain a green pigment called as chlorophyll, which captures the light energy that drives the reactions of plant photosynthesis. 

Thus, the correct answer is option C.
