Understanding the Process of Transpiration and Water Absorption in Plants

The video explains transpiration in plants, where water evaporates from leaves, creating a pull that draws water up through the xylem from roots. It also covers how root hair cells absorb water from the soil via osmosis, highlighting the role of stomata and guard cells in regulating water loss.

What is the primary function of stomata in the process of transpiration?

• To absorb sunlight for photosynthesis

• To allow gases to move in and out of the leaf

• To store water for the plant

• To transport nutrients from the soil

Which cells control the opening and closing of stomata?

• Phloem cells

• Guard cells

• Xylem cells

• Root hair cells

How does the transpiration pull affect water movement in plants?

• It stores water in the leaves

• It pushes water down to the roots

• It pulls water up through the xylem

• It evaporates water from the soil

What is the role of root hair cells in water absorption?

• They store excess water

• They increase surface area for water absorption

• They transport water to the leaves

• They convert water into nutrients

In the process of osmosis, water moves from a _______ solution to a _______ solution.

• concentrated; dilute

• dilute; concentrated

• neutral; acidic

• basic; neutral
