Question

Write the functions of following:
a) Areolar tissue
b) Lymph
c) Golgi bodies
d) Nucleus
e) Protective tissue in plants​

Answer 1

Explanation:

Areolar tissue

binds skin to the muscles beneath. This loose connective tissue also forms a link between organs - while also enabling a high degree of movement between adjacent body parts.

The key functions of areolar tissue can be summarised as providing:

• Support
• Strength, and
• Elasticity.

Lymph

• An important function of lymph is that it captures the bacteria and bring them to lymph nodes, where they are destroyed.
• It also helps in the absorption of fatty acids and transport of fat and chyle to the circulatory system. It helps in the production of immune cells- lymphocytes, monocytes antibody-producing cells (plasma cells).

Golgi bodies

The job of the Golgi apparatus is to process and bundle macromolecules like proteins and lipids as they are synthesized within the cell. The Golgi apparatus is sometimes compared to a post office inside the cell since one major function is to

• modify
• sort, and
• package proteins to be secreted.

Nucleus

The nucleus is a highly specialized organelle that serves as the information processing and administrative center of the cell. This organelle has two major functions:

• it stores the cell's hereditary material, or DNA, and
• it coordinates the cell's activities, which include growth, intermediary metabolism, protein synthesis, and reproduction (cell division).

Protective tissue in plants

It includes epidermis and cork.

Epidermis :

It includes epidermis and cork.Epidermis :It is usually present in the outermost layer of the plant body such as leaves, flowers, stem and roots.

The main function of epidermis is to protect the plant from

• desication and
• infection.

Cork :

As roots and stem grow older with time (increase in girth), tissues at the periphery become cork cell.Cork cells are dead cells and they do not have any intercellular spaces.

• Cork is protective in function.
• cork cells prevent desiccation (loss of water from plant body),
• infection and
• mechanical injury.
