the net movement of water molecules through a selectively-permeable membrane from high to low concentration of water molecules

the net movement of particles against a concentration gradient using energy

a difference in the concentration of particles from one area to another

a specialised plant cell found in the roots that absorb water and nutrients into the plant

Plant roots are adapted to absorb water and mineral ions

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

carbon dioxide + water --> glucose + oxygen

oxygen + glucose --> water + carbon dioxide

water + glucose --> carbon dioxide + oxygen

carbon dioxide + glucose --> water + oxygen

Which is the correct word summary for photosynthesis?

Water can leave the plant via pores in the leaves called {{}}.

Match each mineral to how it is used by plants.

Match each substance to how it is absorbed by plants.

It increases the transfer of energy for active transport.

It increases the concentration gradient to speed up osmosis.

It increases the surface area to speed up diffusion.

It increases the ability of a cell to move.

The ‘hair’ of a root hair cells is what distinguishes it from other root cells. How does the hair adapt a root hair cell for its function?

The diagram shows a root hair cell with many mitochondria. What is the function of mitochondria?

Water is needed by plants for photosynthesis. Where do plants get this water from?

Which subcellular structure in plant cells is the site of photosynthesis?

Which gas in air is needed for photosynthesis?

Which gas made by photosynthesis is excreted by leaves during daylight?

use of energy to move particles against a concentration gradient

net movement of particles from a region of high to lower concentration

a difference in concentration of particles from one region to another

the diffusion of water molecules through a membrane

During active transport, a {{}} protein in the cell membrane changes shape to transport particles through the membrane against a concentration gradient.
