The effect of gravity on the growth of seedlings: practical

Biology

Pupils will learn about uses of gene technology in medicine, such as for genetic testing, and in agriculture, such as the production of genetically engineered crop plants with desirable characteristics.

Pupils learned about the roles of hormones in human reproduction, including control of the menstrual cycle, and other uses of hormones such as in in contraception.

Plant growth and development

Physical activity and equipment requiring safe use

Use of equipment that may require supervision for safety, e.g. scissors in KS1, needles, paint, knives, cooking.

Which of the following are features of biological drawings?

What is the plant response to gravity known as?

True or false? Shoots use positive gravitropism.

Soak the beans for 24 hours and then select three that have germinated.

Secure in a zipped food bag with wet kitchen roll.

Observe the growth of the seedlings and produce scientific line drawings.

Put these steps in the right order for investigating gravitropism.

The auxin accumulated on the upper side of the shoot, promoting cell elongation.

The auxin accumulated on the upper side of the root, inhibiting cell elongation.

The auxin accumulated on the lower side of the root, inhibiting cell elongation.

The auxin accumulated on the lower side of the shoot, promoting cell elongation.

In the following example, why has the shoot grown upwards and the root grown downwards?

Which plant hormones control phototropism?

Match each part of the plant to the effect auxin has on it.

Look at this image of a shoot. From which direction is the light coming?

Gravitropism is a plant's response to {{}}.
