Question

The component of cell wall with hereditary material is
A. Nucleus
B. Protoplasm
C. Cytoplasm
D. Plastid

Answer 1

A cell is the basic structural and functional unit of life or the building block of the body of a living organism. Depending on the number of cells possessed by an organism, an organism is of two types namely unicellular (single celled) or multicellular (many celled) organism.

Complete answer:
The component of the cell wall with hereditary material is no less. A cell is the basic building block in the body of a living organism. A cell possesses various kinds of structures that are referred to as cell organelles. The cell is composed of the outermost protective layer that covers the cell and provides mechanical support to the cell is called cell wall. One more covering is formed outside the cell called as plasma membrane that is product to bacterial and plant cells. The different types of cell organelles are: - Cytoplasm, nucleus, chloroplast, mitochondria, Ribosomes etc.

1. Cytoplasm: A dense, liquid- milk like substance present inside the cell is called cytoplasm. It helps in transport of substances inside the cell.
2. Nucleus: The nucleus of a cell takes part in transmission of characters. The nucleus is covered by a membrane called nuclear membrane nucleus containing the nuclear material or genetic material that transfer characters from parents to offspring.
   3)Protoplasm: The protoplasm is a dense, liquid substance in which various cell organelles are suspended.
3. Plastids: Plastids are double membrane organelles that take part in the preparation and storage of food.
4. Mitochondria: It is called a powerhouse of cells. It synthesis energy in the form of ATP.

Therefore, the correct answer is option (A) Nucleus.

Note: The various functions of nucleus are,
i) The nucleus represents a site responsible for the initiation of the genetic transcription from the translation spot within the cytoplasm.
ii) It is responsible for exhibiting its control over the organism hereditary characteristics.
The organelle participates in varied processes such as cell division, protein synthesis, growth, and cellular differentiation.
iii) This represents an active site for storage of RNA and proteins enclosed within the nucleolus.
iv) It aids in selectively transporting regulatory factors and energy molecules throughout the nuclear pores.
v) It is often known as the brain of the cell
