What is turgor pressure?

Back

Turgor pressure is the pressure exerted by the fluid (usually water) inside the central vacuole of a plant cell against the cell wall, helping to maintain the plant's structure and rigidity.

Front

What role does turgor pressure play in plants?

Back

Turgor pressure helps maintain the shape and firmness of plant cells, allowing plants to stand upright and support their leaves and flowers.

Front

What happens to turgor pressure when a plant loses water?

Back

When a plant loses water, turgor pressure decreases, causing the plant to wilt and lose its rigidity.

Front

What is the relationship between turgor pressure and osmosis?

Back

Turgor pressure is influenced by osmosis, as water moves into the plant cells through osmosis, increasing the internal pressure against the cell wall.

Front

What is the effect of high turgor pressure on plant cells?

Back

High turgor pressure makes plant cells firm and helps them maintain their shape, which is essential for the overall health of the plant.

Front

What is the difference between positive and negative tropism?

Back

Positive tropism is growth towards a stimulus (like light), while negative tropism is growth away from a stimulus (like gravity).

Front

What is phototropism?

Back

Phototropism is the growth of a plant in response to light, where the plant bends towards the light source.

Front

What is gravitropism?

Back

Gravitropism is the growth of a plant in response to gravity, where roots grow downwards (positive gravitropism) and stems grow upwards (negative gravitropism).

Front

What is thigmotropism?

Back

Thigmotropism is the growth of a plant in response to touch or physical contact, often seen in climbing plants.

Front

What are stimuli in the context of plant growth?

Back

Stimuli are changes in the environment that trigger a response in plants, such as light, gravity, and touch.
