Question

Define the following terms:(a)epidermis tissus
(b)Nervous tissue
(c)prokaryotic tissue
(d)nucleus​

Answer 1

Explanation:

(a) EPIDERMIS TISSUE: The epidermis, is the outermost layer of skin, provides a waterproof barrier and creates our skin tone.

(b) NERVOUS TISSUE: The cells of nervous tissue are highly specialized and the cells of this tissue are called nerve cells or neurons. Nervous tissue stimulates and transmits the stimulus very rapidly from one place to another within the body.

(c) PROKARYOTIC CELL: A prokaryote is a cellular organism that lacks an envelope-enclosed nucleus.

(d) NUCLEUS: A usually round part of most cells that is enclosed in a double membrane, controls the activities of the cell, and contains the chromosomes.

YOUR ANSWER.

Answer 2

EPIDERMIS TISSUE :

• It covers body surface and lines hollow organs, body cavities duct.
• It also forms glands.
• It provides protection and helps in excretion, absorption and reproduction.

NERVOUS TISSUE :

• The neural tissue develops from the ectoderm of the embryo, but the microgliocytes arise from the mesoderm of the embryo.
• The species properties of cells of the nervous tissues are, excitability and conductivity.
• Neural tissue has the greatest control over the body's responsiveness to changing conditions.

PROKARYOTIC CELL :

• Prokaryotes are singled cell organisms.
• Chromosomes are single.
• Size is generally small (1 - 10 μ).

NUCLEUS :

• The membrane bound organelle that contains genetic material of eukaryotic organsims is called as nucleus.
• Cell nucleus contains all the cell’s genome.
