Using a microscope to observe effects of osmosis in plant cells: practical

The importance of maintaining constant conditions in the body

The importance of maintaining constant conditions in the body, including osmosis

The role of the skin in thermoregulation

Controlling water balance: the kidneys, and nephron structure

The roles of the nervous and endocrine systems in controlling water balance

Pupils will learn about factors that affect the rate of photosynthesis in plants, including temperature, light intensity and carbon dioxide concentration.

Pupils learned how substances essential for chemical reactions, and the products of the reactions, are transported into, around and out of plants, and about factors affecting the rate of water uptake by a plant.

This unit covers the importance of maintaining a constant internal environment, focusing on body temperature control, osmotic balance, and kidney function. It explains the roles of the skin, kidneys, and ADH, and emphasises data extraction, experiment techniques, and accurate data interpretation.

Coordination and control: maintaining a constant internal environment

Starting from the point of being triggered by a stimulus, put these parts of the nervous system pathway in the correct order.

Internal body temperature can be affected by a variety of factors. Select the external factors.

Match each part of the nervous system to the part of the body that has that role.

The {{}} instructs muscles to contract to make us shiver when our body temperature decreases.

Look at this cross-section through the skin and match the selected parts to the correct labels.

Jun: The body's responses to changes in temperature are antagonistic.

Laura: The body's responses to changes in temperature are conscious.

Aisha: The body's responses to changes in temperature are autonomic.

Izzy: The body's responses to temperature change aren't controlled by the brain.

Whose descriptions of the body's responses to changes in temperature are correct?

Which parts are included in the nervous system?

Which label points to the sweat gland in the skin?

Which of the following responses occur when we get too hot?

causes hairs to lie flat or stand upright

Match the part of the skin to its function.

Significantly high body temperatures are dangerous because they can cause enzymes to {{}}.

layers of warm clothing and a hot water bottle
