Life cycles of 
flowering plants
Flowering and Non-Flowering 
Plants: Plants with flowers
Diversity of Flowers
Many plants have flowers, and these are known as flowering plants.
Flowers vary greatly in size, ranging from tiny blooms to large, 
beautiful displays.
Colour Variations
Flowers come in a wide range of colours.
Some flowers are brightly coloured to attract pollinators, while others 
have softer hues.
Scent Characteristics
Some flowers produce unique scents or fragrances to attract certain 
pollinators.
However, not all flowers have a scent, and some remain fragrance-
free.

Plant life cycles
Flowering
Plants produce flowers that last only a few days before they die and fall 
off.
Fruit Formation
Part of the flower remains and becomes the fruit, with seeds forming 
inside.
New Growth
Seeds grow into new plants that eventually produce their own flowers.
Cycle Continues
The new plants grow and produce flowers to form new fruits and 
seeds.
All the changes in a flowering plant, from flowers to seeds growing into new plants, 
are called the plant's life cycle. A cycle is something that happens over and over 
again, with different stages occurring in a predictable sequence.

Plants without flowers
Non-flowering Plants
Not all plants produce flowers. Plants 
without flowers are called non-flowering 
plants. These include mosses, ferns, and 
plants with cones like pine trees.
Spore Production
Some non-flowering plants, such as ferns 
and mosses, do not form seeds. Instead, 
they produce tiny spores that can grow 
into new plants when conditions are right.
Seed-producing Non-flowering Plants
Other non-flowering plants, such as pine 
trees, do form seeds. However, their seeds 
develop in cones rather than from flowers.
Conifers
These cone-bearing plants are called 
conifers and include familiar trees like 
pines, spruces, and firs. Their reproductive 
strategy differs significantly from flowering 
plants.
