Plant Transport

The video explains how plants transport water from roots to leaves, overcoming challenges posed by gravity. It describes the structure and function of phloem and xylem tubes, highlighting the role of osmosis in water uptake by roots. The process of transpiration, which creates a suction force to draw water upwards, is detailed, emphasizing that water is pulled rather than pushed to the top of the plant.

What is the primary function of phloem tubes in plants?

• Transporting water from roots to leaves

• Absorbing nutrients from the soil

• Carrying sugars from leaves to other parts

• Providing structural support to the plant

Which part of the plant is responsible for drawing water and minerals from the roots to the leaves?

• Phloem

• Xylem

• Leaf cells

• Root hair cells

How do root hair cells contribute to water absorption in plants?

• By transpiration

• Through active transport

• By photosynthesis

• Through osmosis

What process generates the suction force that pulls water up through the xylem?

• Respiration

• Transpiration

• Osmosis

• Photosynthesis

Why is water movement in plants described as being 'pulled' rather than 'pushed'?

• Because of gravity

• Due to root pressure

• Because of transpiration

• Due to capillary action
