Plant Life Cycle Knowledge Organiser

About this worksheet

A one-page knowledge organiser for the Year 3 plants unit. Panel 1 labels the flower, leaves, stem and roots of a flowering plant, with the job of each part. Panel 2 defines germination, pollination, fertilisation, seed dispersal and life cycle. Panel 3 shows the cycle in five pictures, from a seed in the soil to a bee on a flower and a dandelion clock blowing away. Panel 4 asks four questions and prints the answers, such as water, oxygen and warmth for what a seed needs to germinate. It follows the England National Curriculum objectives on plant parts and the life cycle.

Curriculum objectives covered

Plants

“Explore the part that flowers play in the life cycle of flowering plants, including pollination, seed formation and seed dispersal.”

The life cycle row shows pollination and seed dispersal, and Key Vocabulary defines fertilisation. Q2 and Q3 ask about dispersal and how bees carry pollen.

Plants

“Identify and describe the functions of different parts of flowering plants: roots, stem/trunk, leaves and flowers”

Plant Parts & Functions gives the job of the roots, stem, leaves and flower, and Q4 asks about the leaves. Trunks are not covered.

What's inside this worksheet

Plant Parts & Functions

A flowering plant in soil with four labels. Each one says what the part does, for example the roots anchor the plant and absorb water and nutrients.

Key Vocabulary

Five terms with definitions, including seed dispersal by wind, animals, water or explosion.

The Flowering Plant Life Cycle

Five pictures joined by arrows: seed, germination, growth, flowering and pollination, and seed dispersal.

Key Questions

Four questions with the answers underneath, including why seeds must be dispersed away from the parent plant and how bees help plants.

How teachers use it

Self-check

Fold back the answer row and ask pupils to answer the four questions before they check A1 to A4.

Sequencing task

Cut out the five life cycle pictures. Pairs put them in order and name each stage without the labels.

Seed dispersal

After Q2, bring in a dandelion clock and some sycamore seeds. Pupils match each one to a method in the Seed Dispersal definition.
