Understanding Turgor Pressure and Mimosa Pudica

The video explains the concept of turgor pressure using the Mimosa Pudica plant, also known as the 'Touch Me Not' plant. When touched, the plant closes its leaves due to the loss of turgor pressure in the pulvini cells at the base of each leaflet. This occurs because specific chemicals are released, causing the cells to lose water, leading to the collapse of the cells and the closing of the leaflets.

What is another name for the Mimosa Pudica plant?

• Shy Plant

• Sensitive Plant

• Sleepy Plant

• Touch Me Not Plant

What is the function of pulvini in the Mimosa Pudica plant?

• They assist in the closing of the plant's leaves.

• They help the plant absorb sunlight.

• They store nutrients for the plant.

• They produce flowers for the plant.

What is turgor pressure?

• Pressure from sunlight on the leaves.

• Pressure from the soil on the roots.

• Pressure from the wind on the plant.

• Pressure applied by water against cell walls.

What happens to the cells in the pulvini when the plant is touched?

• They start to grow rapidly.

• They produce more chlorophyll.

• They lose water and collapse.

• They gain water and expand.

What causes the loss of turgor pressure in the Mimosa Pudica plant?

• Growth of new leaves.

• Absorption of more water.

• Release of certain chemicals.

• Increase in sunlight.
