Questions Related to plant and animal cell

A cell that contains a cell wall, chloroplasts and a central vacuole is-

biology cell structure plant and animal cell cell structure and micro-organisms organisation of the organism

  1. Plant cell.

  2. Animal cell.

  3. Yeast cell.

  4. Bacterial cell.

Show answer
Correct Option: A
Explanation:

Plant cells have a large central vacuole, are surrounded by a cell wall, and have chloroplasts, which are the organelles of photosynthesis. Photosynthesis converts the sun's solar energy into chemical energy. This chemical energy, which is the carbohydrate glucose, serves as "food" for the plant.

Hence A is the correct option. 

Plant cell can do___________

biology cell structure and micro-organisms plant and animal cell cell structure organisation of the organism

  1. Breathing and respiration

  2. Respiration and photosynthesis

  3. Breathing and photosynthesis

  4. All of the above

Show answer
Correct Option: B
Explanation:
The plant cell can do respiration and photosynthesis. The plants get energy through the process of respiration in which glucose food breaks down in the presence of oxygen to form carbon dioxide and water with the release of energy. In plants, photosynthesis takes place in the cell organelle called chloroplast. A plant cell cannot breathe because in a plant body lungs are absent.
So the correct answer is 'Respiration and photosynthesis'.

Which of the following has a rigid cell wall that surrounds the cell membrane?

  1. Plant cell

  2. Animal cell

  3. Viruses

  4. None of the above

Show answer
Correct Option: A
Explanation:

Plant and animal cells have several differences and similarities. For example, animal cells do not have a cell wall or chloroplast but plant cells do. Animal cells are round and irregular in shape while plant cells have fixed, rectangular shapes.

Identification part on plants cell is

  1. Centrosome

  2. Mitochondria

  3. Protoplasmic membrane

  4. Cell wall

Show answer
Correct Option: D
Explanation:

Plant and animal cells have several differences and similarities. For example, animal cells do not have a cell wall or chloroplasts but plant cells do. Animal cells are round and irregular in shape while plant cells have fixed, rectangular shapes.

Which of the following cells tend to have one large central vacuole that can take up to 90% of cell volume?

  1. Bacterial

  2. Plant 

  3. Animal 

  4. None of the above

Show answer
Correct Option: B
Explanation:

The main structural differences between plant and animal cells are the additional structures found in plant cells. These structures include chloroplasts, the cell wall and vacuoles. Vacuoles are large, liquid-filled organelles found only in plant cells. Vacuoles can occupy up to 90% of a cell's volume and have a single membrane. Their main function is as a space-filler in the cell, but they can also fill digestive functions and their interiors can be used as storage for nutrients.  

The outer covering in addition to cell membrane in plants is called as 

biology cell structure and micro-organisms plant and animal cell cell structure organisation of the organism

  1. Plasmalemma

  2. Capsule

  3. Cell wall

  4. Both A and B

Show answer
Correct Option: C
Explanation:

The cell wall is a tough, flexible and sometimes rigid layer that surrounds some cells e.g., plant cells. It surrounds the cell membrane and provides these cells with structural support and protection. In addition, the cell wall acts as a filtering mechanism. Animals do not have a cell wall.

The ................. allows high pressure to build inside of the plant cell without bursting.

biology cell structure and micro-organisms plant and animal cell cell structure organisation of the organism

  1. Cell wall

  2. Cytoplasm

  3. Nucleus

  4. Mitochondria

Show answer
Correct Option: A
Explanation:

The cell wall allows high pressure to build inside of the plant cell without bursting. The plant cell is able to accept large amounts of liquid through osmosis without bursting. This is due to the presence of cell wall which is absent in the animal cell.

A mature plant cell has

biology cell structure and micro-organisms plant and animal cell cell structure organisation of the organism

  1. Cell wall and protoplasm

  2. Protoplasm and vacuole

  3. Vacuole and cell wall

  4. Protoplasm, cell wall, and vacuole

Show answer
Correct Option: D
Explanation:
The protoplasm can be defined as a material which comprises of the living part of the cell including the cytoplasm, nucleus and other organelles. Plant cells are characterized by the presence of large vacuoles and cell wall, which are not seen in animal cells
So, the correct answer is 'Protoplasm, cell wall, and vacuole'.

  1. Only gymnosperm cell

  2. All plant cells

  3. All eukaryotic cell

  4. Only bacterial cells

Pectic material are stained with

  1. Cotton blue

  2. Acetocarmine

  3. Iodine

  4. Methylene blue

Show answer
Correct Option: D
Explanation:

Pectic substances are a group of polysaccharides in plant cell walls and some mucilages, which are endowed with multifunctional properties, such as the control of cell wall integrity and porosity. Methylene blue is used to indicate whether the cells are dead or alive.

 So, the correct answer is 'Methylene blue.'
