1. Flowering plants:
-Flowers are reproductive organs of flowering plants
-Can be divided into 2 groups: monocotyledons &
dicotyledons (depending on the number of
cotyledons in the seeds)
-Cotyledons is the main seed leaf for the germination of
new seedlings.
2.Non-flowering plants
Plants that do not produce flowers
Need to reproduce by other means, for example,
-Algae (alga)
-Mosses (lumut)
