DID YOU KNOW?
Four main groups: It is thought that all modern plants
originated from algae
• Bryophytes -----------------------------------------------------------
• Pteridophytes
• Gymnosperms
• Angiosperms
Plants are divided
into these groups
according to: Note
When talking about plant diversity
1. The presence/absence of
we deal with the Kingdom Plantae.
• Vascular tissue
• True leaves, stems and
roots
• Spores or seeds
• Fruits
2. Their dependency on water
All plants are:
1. Multicellular
2. Eukaryotic – have membrane bound organelles and nucleus
containing their own DNA
3. Have a cellulose cell wall
4. Often contain chlorophyll
