Question

In a cell what are the advantages of rigidity of the cell wall

Answer 1

Answer:

Plant cells are similar to animal cells in both internal function and processes. Both cells contain mitochondria and ribosomes to help process energy and nutrients. However, plant cells have an extra feature that animal cells do not have called the cell wall.

Explanation:

The Plant Cell Wall

In order to describe the functions of the cell membrane and cell wall, we need to define what the cell wall is.

Plant cell walls are rigid membranes on the outermost part of the cell. The cell wall provides a structured shape for the cell, helping the cell retain its form and shape. The cell wall also controls the rate of replication, allowing plant cells to replicate at a much slower rate than animal cells.

The cell wall helps to form the plant cell, but it also helps keep much of the internal functions of the cell, such as processing water, inside the plant. It can also provide structure and stability to the plant overall, allowing it to stand upright and rigid.

Protecting Important Nutrients

A cell wall allows water to work its way into the cell body. The cell wall can do this because the structure of the wall is porous. This allows water to pass into the cell without larger molecules and organisms like pathogens and bacteria entering into the cell. The walls can also process minerals, specifically minerals found in the dirt underneath the root that plants need to function.

Water helps flow these nutrients through the cell wall and into the internal mechanisms of the cell. At the same time, the water is unable to escape. The cell wall captures and pressurizes the water within the cell, keeping the cell properly hydrated.

Osmosis in Plant Cells: Crossing the Walls

A plant cell has three layers of walls: the lambella, the primary, and the secondary wall.

The middle lambella is a wall that connects plant cells with other plant cells with complex proteins. After the lambella is the primary wall, which is the rigid skeletal enclosure for the cell itself. Lastly, after the primary wall comes the secondary wall. This plant cell wall is a compressed wall that pressurizes the inside of the cell.
