Question

Draw the plant cell and explain its leveled parth

Answer 1

Answer:

Cell wall

• It is non-living.
• It is present only in plant.
• A rigid layer of polysaccharides enclosing the membrane of plant and prokaryotic cell .
• It maintains the shape of cell.
• It is a protective layer.

Cell membrane

• It is also called plasma membrane.
• It is present in all organism.
• It is a thin membrane enclosing the cytoplasm of cell.
• It is the selectively permeable membrane.

Endoplasmic reticulum

• It is a cell organelle found in the inner portion of the cytoplasm of cell.

It is of two types

1. SER

• Full form of SER is smooth endoplasmic reticulum.
• It is responsible for lipid synthesis.

2. RER

• Full form of RER is rough endoplasmic reticulum.
• It is responsible for the synthesis of protein.

Nucleolus

• A small round body of protein in a cell nucleus.
• This organelle contain RNA and involved in protein synthesis.

Nucleus

• A part of the cell containing DNA and RNA and responsible for growth and reproduction.

Mitochondria

• It is a doubled layered.
• It is called as powerhouse of the cell.
• It is sausage or cylindrical in shape.
• It is a cell organelle containing enzymes responsible for producing energy.

Chloroplast

• It is green in colour due to presence of chlorophyll.
• It is mainly responsible for photosynthesis.

Vacuole

• Vacuoles can occupy 90% volume of cell in plant cell.
• Vacuoles are absent or less in number in animal cell.
