transport in plants

Recall the main funtion of a phloem cell.

• To transport nutrients (mainly sucrose) to different parts of a plant.

• To transport water to different parts of a plant.

• To make energy for the plant via photosynthesis.

• To provide structural support to a plant.

What is the effect of increasing leaf area on transpiration?

• It increases transpiration rate
• It decreases transpiration rate

The plant transport system is made up of ____ types of tubes.

• 1
• 2
• 3
• many

Which of the following is a dead tissue?

• Phloem

• Xylem

• Cortex

• Spongy mesophyll

The loss of water vapour from the leaves of a plant.

• Transpiration

• Evaporation

• Translocation

• Photosynthesis

Where does sugar transport begin?

• Roots

• Leaves

• Root hairs

• Vascular bundles

This kind of arrangement of vascular bundles can be seen in the ............?

• leaf

• stem

Evaporation of water from leaves is important as

• It cools the leaves and helps water to move up the plant.

• It makes the plant wilt
• It helps the plant to respire

What is the name of the part of the root that allows water and minerals enter?

• root hairs
• epidermis
• phloem
• phyla

Transpiration is

• the movement of water through a plant from the roots up the stem
• the loss of water from the leaves of a plant by the process of evaporation
• the flow of water into plant roots by osmosis from the soil
• the process of minerals and sugars moving through plant veins
