AQA Biology P1 Plant Transport

Vascular tissue that transports water and minerals UPWARDS from a plant's roots is know as ______.

• Chlorophyll
• Phloem
• Stomata
• Xylem

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

• 1
• 2
• 3
• many

Water vapour exits a plant leaf by

• the stomata
• the epidermis
• the palisade cells
• the spongy mesophyll

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

• It increases
• It stays the same
• It decreases
