What is the main function of cork?

Function of Cork Cells Cork cells prevent water loss from plants and also make them more resistant to bacterial and fungal infection.

What is the structure of a cork?

The cork structure is compact with a very regular arrangement of the individual cells and without intercellular spaces. The cells are in general hexagonal prisms that are stacked base-to-base in radial rows, and the rows aligned in parallel; in adjacent rows, the prism bases often lay in staggered positions.

What is cork describe its structure and function?

A mature cork cell is non-living and has cell walls that are composed of a waxy substance that is highly impermeable to gases and water called suberin. FUNCTIONS OF CORK ARE:- :} they are protective in nature. :} they prevent desiccation (loss of water from plant bodies), infection and mechanical injury.

What structural characteristics does the cork possess to perform these functions?

Cork has low density, is buoyant, is not very permeable to fluids, has a low thermal coefficient, exhibits elasticity and deformation without fracturing under compression, and has…

What are the characteristics of cork?

Answer: The characteristics of cork are as follows:

• Cells of cork are dead at maturity.
• These cells are compactly arranged.
• Cells do not posses intercellular spaces.
• Cells possess a chemical substance ‘suberin’ in their walls.
• There are several thick layers.

What is the function of cork for Class 9?

Cork protects the plants by acting as a cushion against any physecal or mechanical injuries. 2. The cells of the cork are rich in suberin, which is a jelly like compound. This does not allow easy loss of water from the plants and trees and regulates the exchange of gases between the palnts and its surroundings.

What cell structures do you see when looking at cork cells?

This separation is believed to be caused by structures that arise from the cork cambium, known as lenticels. These lenticels or pore-like structures as can be seen in higher powers allowing for the exchange of gases between the outside environment and the stem of the plant.

What is the function of cork Class 9?

Which characteristics of cork make it a protective tissue?

The cork cells are dead and compactly packed with no intercellular space. Their cell walls are coated with a waxy substance, suberin, which do not allow water and gases to pass through. Therefore, it protects the plant against mechanical injury and also prevents the loss of water by evaporation.

What is cork in biology class 8?

Cork is the outer protective layer of bark of a tree. The cork cells are dead and compactly packed with no intercellular space. Their cell walls are coated with a waxy substance, suberin, which do not allow water and gases to pass through.

Does a cork have cell walls?

A mature cork cell is non-living and has cell walls that are composed of a waxy substance that is highly impermeable to gases and water called suberin.
