Answer No 1)
The structure A is parenchyma cells.
The structure B is lymphocytes.
The structure C is White blood cells
The structure D is xylem cells.
Explanation:
The structure A represents the parenchyma cells whose main function is in storage and photosynthesis inside the plant cells.
The structure B represents the white blood cells which play an active role in our immune defense system.
The structure C represents Unstriated muscle fibre cell which are involved mainly in the movement of food.
The structure D represents the Xylem tissue whose main function is to carry water across the plant body.
Answer 2)
The figure D represents the Xylem cells. The main function of the Xylem cells is to carry water from the roots to the other parts of a plant. The plants are known to have two major types of vascular tissues. The phloem tissue which carries food from the leaves to other plant parts and the xylem tissue which carries water from the roots to the other parts of the plant.
Answer 3)
Structure B (white blood cells) are found in the liquid plasma of the blood.
White Blood cells can be described as the cells of the immune system which are involved in providing the body protection against pathogens and infectious diseases. The white blood cells can be found in the blood and the lymphatic system. The white blood cells are produced in the bone marrow.
Answer 4)
Structure C (Unstriated muscle fibres) are found in the internal organs such as walls of the intestine and help in the passage of food.
The Unstriated muscle fiber cells can be described as the types of muscles cells whose movement is involuntary or without our control. They are also known as the smooth muscles and can be seen in the walls of many internal organs. They contract involuntarily.
Answer No 5)
The neuron cell consists of a soma which is the cell body. The cell body of the neuron consists of nucleus, smooth and rough endoplasmic reticulum, Golgi apparatus, mitochondria, and other cellular components.
The dendrites are the branch like structures of the neuron cell.
The axon is an tube like structure of the neuron cell which carries electrical impulses.
The synapse is the chemical junction between the axon terminals of one neuron and the dendrites of the next.
