What is the primary function of roots in plants?

Fill in the blank: Water is essential for the process of ___, which allows plants to produce food using sunlight.

Photosynthesis

True or False: Transpiration is the process by which plants absorb water from the soil.

False. Transpiration is the process of releasing water vapor from the plant, not absorbing it.

Riddle: I am vital for your structure and support, without me, you would droop and distort. What am I?

Multiple Choice: Which of the following is NOT a function of water in plants? A) Nutrient transport B) Photosynthesis C) Energy production D) Structural support

C) Energy production

What role does surface area play in the water absorption capacity of roots?

The extensive surface area provided by rootlets and root hairs is crucial for maximizing water absorption from the soil.

Describe the process of imbibition and its significance in plants.

Imbibition aids seed germination.

• Water absorption in cells.

• Causes seed coats to swell.

• Crucial for early plant growth.

What is the significance of the thin cell walls of root hairs in water absorption?

Thin walls enhance water absorption.

• Facilitates easy water flow.

• Enhances nutrient uptake efficiency.

• Supports root hair function.

Explain how osmosis differs from diffusion in the context of root water absorption.

Osmosis moves water; diffusion moves all.

• Water moves through membranes.

• Diffusion involves all substances.

• Osmosis affects plant hydration.

True or False: Diffusion requires a semi-permeable membrane to occur.

False

Diffusion does not need membranes.

• Occurs in open space.

• Movement from high to low.

• Essential for cellular processes.

What happens to a plant cell when it becomes flaccid?

Plant cells become limp.

• Loss of water occurs.

• Decreased turgor pressure.

• Can lead to wilting.

Fill in the blank: Turgidity in plant cells is maintained by ___ pressure exerted against the cell wall.

Turgor

Riddle: I am the state when a plant cell is swollen and firm, but without me, the plant would droop and squirm. What am I?

Turgidity

True or False: In an isotonic solution, the shape and size of the cell remain unchanged.

True
