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

Plant roots are adapted to absorb water and mineral ions

Observing the structure and distribution of stomata: practical

Transport systems in plants: phloem and translocation

Observing xylem and phloem using a light microscope: practical

The effect of light on water uptake by a plant: practical

The effects of environmental factors on the rate of water uptake by a plant

The importance of exchange surfaces and transport systems in plants

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.

This unit covers water and mineral uptake in plants, focusing on root hair cells, xylem, and phloem. It includes transpiration, translocation, and factors affecting water uptake. Emphasis is on rate calculations, graph interpretation, experiments, and data analysis.

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 diagram 2_v2

Cells are joined together to make a continuous tube.

Which of the descriptions does **not** apply to xylem?

movement of water from the roots to the leaves of plants

substances needed to make proteins and chlorophyll

plant cells lacking enough water to make them firm

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.

Which gas is a reactant in photosynthesis?

transport water and minerals from the root to the rest of the plant

pores that open to allow gasses to move in and out of leaves

Match each structure to its correct function.

How do plants absorb nitrate ions from the soil?

Plants roots absorb magnesium ions from the soil. Why do plants need magnesium?
