A plant is a living thing that often has roots, a stem and leaves.

Living things need certain conditions to grow and be healthy.

The requirements of something are the things it needs.

In a comparative test, the thing that is being changed has labels, such as the types of materials.

The things that can be changed, measured or kept the same in a comparative or fair test.

What plants need: plan

Science

What plants need: do

Nutrients and fertilisers for plants (non-statutory)

The function of leaves

The function of roots

Plants without roots

How water is transported  in plants

What plants need: review

The function of flowers

The parts of a flower

Pollination

Seed formation and seed dispersal

Life cycle of a flowering plant

What plants need: final review

Comparing what plants need in different habitats

In this What plants do and what they need unit, pupils learn about the part that flowers play in the life cycle of flowering plants. In the Reproduction and life cycles unit: plants, they will build on this knowledge to describe the life process of reproduction in some plants

In the Growing plants unit, pupils learnt that plants need water, light and a suitable temperature to grow and stay healthy. In this What plants do and what they need unit, pupils will build on this knowledge to explore a greater number of requirements of plants for life and growth and how they vary from plant to plant

This unit explores the functions of different parts of flowering plants, including roots, stems, leaves, and flowers. It investigates plant requirements for growth and the role of flowers in pollination, seed formation, and dispersal. Emphasis is on practical enquiries, and data presentation.

What plants do and what they need

Variables are the things that can be changed, measured or kept the same in a comparative or fair test.

To record information is to keep it so that it can be passed on to others. This can be done in many ways including notes, photos and drawings.

Soil is ground up rock mixed up with plant and animal remains.

Anything which is alive or was once alive is organic.

A nutrient is any substance that plants or animals need in order to live or grow.

A substance containing nutrients that we can add to soil to make it better for growing plants.

Something that is human-made is made or caused by humans.

A leaf is the part of a plant where the plant makes its food using the process of photosynthesis.

The task that something has is its function.

Carbon dioxide is a type of gas that is in the air around us.

The way in which plants make food in their leaves is called photosynthesis.

In an observation over time investigation, we observe and record how something changes over a period of time.

The part of a plant that anchors it in the soil is called the root. Roots take in water and nutrients for the plant.

Roots help to anchor the plant by placing it firmly in the soil.

To observe is to look very closely and use other senses too.

The stem of a plant supports the leaves and flowers.

To transport something is to move it from one place to another.

A question is a type of sentence that asks something.

Data is information collected during an investigation. It may be numbers, symbols, pictures or text.

A diagram is a drawing used to explain something clearly.

A label is a sign that gives us information about the thing it is with.

A prediction is a statement saying what you think will happen.

A flower is the part of a plant that enables it to reproduce.

A life cycle is the way in which a living thing changes as it ages.

When living things reproduce they create their offspring.

Pollination is the transfer of pollen from the male reproductive parts of a flower to a female one.

A petal is a part of a flower which is often colourful and attracts insects to pollinate the flower.

The male parts of a flower are called the stamen.

The anther is a part of the stamen that produces and holds pollen.

The stigma is a sticky part at the top of the female parts of a flower.

Seeds are formed inside the ovary of a flower.

Pollen is a very fine powder made by the anthers of a flower.

Pollination is when pollen from a male anther is transferred to the female stigma of a flower.

A pollinator is an animal that pollinates a flowering plant.

Pollination is when pollen from an anther is transferred to the stigma of a flower.

Fertilisation happens when pollen from an anther reaches the ovary in a flower.

Seed formation happens inside flowers after a plant has been fertilised.

Seed dispersal is the way seeds are spread out from their parent plant.

A life cycle is the way in which a living thing changes throughout its life.

Germination is when a plant starts to grow from a seed.

We compare things by looking at what is the same and what is different.

In a conclusion, scientists explain what their results show or mean.

To explain something means to make it clear.

To evaluate is to think about what you did and suggest any changes or improvements.

The place where a plant or animal lives is called its habitat.
