specialised vessels in plants that transport sugar, amino acids and other nutrients

the process of transporting sugars and nutrients through the phloem

the location that the sugars or nutrients are loaded during translocation

the location that the sugars or nutrients are unloaded during translocation

the net movement of particles against a concentration gradient using energy

Transport systems in plants: phloem and translocation

Combined science

Plant roots are adapted to absorb water and mineral ions

Transport systems in plants: xylem and transpiration

Observing the structure and distribution of stomata: practical

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

Some of the __________ produced by photosynthesis is used in cellular respiration to transfer energy for life processes.

All cells with chloroplasts can photosynthesise.

the transport of sugars and other nutrients in plants

specialised tissue for the transport of water and minerals

specialised tissue for the transport of sucrose and amino acids

Match each keyword to the correct meaning.

thousands of glucose molecules joined together

Cells in plant leaves are like factories for the production of biological molecules. Match each biological molecule to the components from which it is made.

phloem cells have sieve plates between them

phloem tissue transports only from the leaves to the roots

Which of these is **not** true of phloem tissue?

Active transport moves sugars from the source into the phloem.

This increases the concentration of sugar in the phloem.

The water increases the pressure in the phloem.

Sugar solution moves towards the sink by translocation.

Put these stages of translocation in the correct order.

Which part of the plant pictured - **A**, **B**, **C** or **D** - absorbs water for photosynthesis?

Which part of the plant is adapted to make a lot of glucose by photosynthesis?

Name the vessels that transport water from the roots to the leaves in plants.

What may happen to a non-woody plant if the rate of uptake of water by the roots is less than the rate of transpiration?

It will increase the rate of cellular respiration.

It will decrease the rate of photosynthesis.

It will increase the rate of transpiration.

It will decrease the rate of transpiration.

When it is dark at night, plants close their stomata. How will this affect life processes in the plant?

the top surface of a leaf is warmer than the lower

there are more air spaces on the upper surface

Which statement explains why the majority of stomata are on the underside of leaves?
