Phanerogams are classified depending on the presence or absence of fruits. They are of two types:
(i) Gymnosperm possesses naked seeds, i.e., not enclosed by fruits.
(ii) Angiosperms, in which the seeds are enclosed within the fruit.
Angiosperms are further divided into two types:
(i) Monocotyledons, which have a single cotyledon in their seeds, e.g., wheat, rice, etc.
(ii) Dicotyledons, which have two cotyledons in their seeds, e.g., gram, pea, etc.
