substances that are essential for healthy plant growth, including nitrates and magnesium

specialised vessels in plants that transport water and mineral ions

pores in the leaf through which water, oxygen and carbon dioxide can diffuse

the loss of water from a plant’s leaves

the continuous movement of water from the roots to the leaves through the xylem

Transport systems in plants: xylem and transpiration

Biology

Pupils will learn about ways in which the human body maintains a constant internal environment in response to internal and external change, including changes in temperature and water balance.

Pupils learned about aerobic and anaerobic cellular respiration, including the chemical reactants and products of the processes, and practical ways to measure the rate of cellular respiration in living cells.

Transport and exchange surfaces in plants

What is the name of the part of the plant that has hair cells to absorb water?

provides a large surface area for the absorption of water and minerals

a tissue in plants that transports water and mineral ions

open and close to enable gas exchange and control water loss

Match each structure to its correct role.

Stomata are surrounded by two {{}} cells that open and close the pore.

plant cells full of water making them swell and become firm

only from the roots, up the stem to the leaves

only from the leaves, down the stem to the roots

In which direction are water and dissolved mineral ions moved through the xylem?

Which part of a plant absorbs water from the surroundings?

Producers use water in a process called {{}} to make glucose, which requires energy from light.
