Year 5 Summer Term 2 Science
New topic: Living things and their habitats – Life Cycles
As we continue to look at the life cycles of living things, this lesson
looks at the life cycle of a flowering plant.
Follow the slides in order, reading each one carefully.
Try to answer each question before reading the answers on the
next slide.
Copy and paste the video links in your browser when you see them.
For the task: Print off the activity sheet or create your own on
paper.
LO: to explore and discuss the life cycle of a flowering plant.
Watch this video of a dandelion changing
from a flower to a seed head.
Think about what different phases the
dandelion displays and which stage of its
lifecycle is it in.

What are the phases of the life cycle of a flowering plant?
TOP TIP: there are 6
LO: to explore and discuss the life cycle of a flowering plant.
The 6 phases are:
1. Seed dispersal
2.Germination
3.Roots and Stem
4.Leaves and Flowers
5.Pollination
6.Fertilization
These fit into 3 stages. Can you name them?
LO: to explore and discuss the life cycle of a flowering plant.
The 3 stages are:
1. Birth
2. Development
3. Reproduction
The 6 phases take place during each stage:
Birth - Seed dispersal
- Germination
Development - Roots and Stem
- Leaves and Flowers
Reproduction - Pollination
- Fertilization
Can you describe what
happens during each of
the 6 phases?

Seed dispersal (Birth)
This is the beginning of a plant's lifecycle. A seed can
be dispersed from a flower in a number of ways. Two
common ways are through the wind like a dandelion or
by animal transportation such as by birds and bees.
Trees that produce fruits and berries, such as
Elderberry trees, rely on birds to eat and then dispose of
their seeds in various locations.
LO: to explore and discuss the life cycle of a flowering plant.
Germination (Birth)Once a seed lands
and becomes
embedded within
soil, providing the
conditions are
correct (nutrients,
hydration), the seed
will then germinate
and produce two
shoots: roots and
stem.
LO: to explore and discuss the life cycle of a flowering plant.
Roots and Stem (Development)The plant then
begins to develop
its root system
and a strong
stem. These two
components are
essential for the
survival of a
plant.
LO: to explore and discuss the life cycle of a flowering plant.
Leaves and Flowers (Development)
The plant will then produce leaves and flowers; each has their
own unique purpose:
Leaves absorb sunlight and create food for the plant.
This is known as photosynthesis!
Flowers are colourful and fragrant. This attracts insects, such as
bees, to visit the plant. During this phase, the stamen (make organ)
will produce pollen and the stigma (female organ) will become
sticky.

Pollination (Reproduction)
Once the plant
has flowered, it
then moves to the
reproductive stage
of its lifecycle.
