Plants can be classified into two groups:
1. Green plants and fungus
2. Flowering and non-flowering plants
They lack chlorophyll and are therefore not able to manufacture their own food by photosynthesis.
They instead, take-in their nutrients from dead and decaying animal or plant materials.
Examples of such plants are bread mould, mushrooms, toad stool and puffball.
Flowering plants:
Plants that produce flowers are called flowering plants.
It is through the flowers that seeds and fruits are formed.
A plant can then germinate from the seeds or fruits.
Examples of flowering plants are maize, oranges, beans, bougainvillea and hibiscus.
Plants that do not produce flowers are called non-flowering plants.
These plants cannot reproduce by producing seed.
Instead, the non-flowering plants reproduce through production of tiny structures called spores.
Examples of non-flowering plants are bread mould, mushrooms, algae (simple plants which make pond water green) fern and lichens.
