a chemical process that requires energy transferred from its surroundings

a feature that helps an organism to function and survive

subcellular structure in which photosynthesis takes place

green pigment in chloroplasts, to which energy is transferred by light

pores (holes) in the surface of a leaf, through which water, oxygen and carbon dioxide can diffuse

Photosynthesis: an endothermic process that takes place in chloroplasts

Combined science

Pupils will learn more 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.

Pupils learned how hormones and glands of the human endocrine system enable us to coordinate and control changes in our bodies.

This unit explores photosynthesis as the basis for food and biomass, examines cell structure and adaptations in eukaryotic and prokaryotic cells, and covers the photosynthesis process. It focuses on using models and theories to develop hypotheses, interpret data, and present reasoned explanations.

Photosynthesis: requirements and products

The subcellular structure in which photosynthesis takes place is called a __________.

Light transfers the energy required for photosynthesis to a green pigment called __________.

The process of photosynthesis is described as __________ because it requires energy transferred from its surroundings.

Complete the balanced symbol equation for photosynthesis by adding one molecule of glucose.

Leaves have many pores (holes) in their surface called {{}}, through which water, oxygen and carbon dioxide diffuse.

to take in carbon dioxide for photosynthesis

to release waste carbon dioxide made by photosynthesis

to release waste oxygen made by photosynthesis

glucose + oxygen --> water + carbon dioxide

glucose + carbon dioxide --> water + oxygen

water + carbon dioxide --> glucose + oxygen

water + oxygen --> glucose + carbon dioxide

What is the correct word summary for photosynthesis?

True or false? Producers use all the glucose made during photosynthesis as a fuel for cellular respiration.

Producers use some of the glucose made by photosynthesis as a source of materials to build biomass. Match each type of biomass to the correct example.

The glucose made by photosynthesis is made up of carbon, hydrogen and oxygen. This is combined with {{}} from mineral ions to make proteins.

Aisha: Consumers can survive without producers.

Lucas: The only reason producers make biomass is to feed consumers.

Sam: Producers are the source of biomass for food chains.
