alekssr [168]

<u>Answer</u>: A - Bryophytes

            B - Gymnosperms

            C - Angiosperms

            D - Dicots

Land plants are divided into non-vascular and vascular plants, according to the presence or absence of a conducting tissue. The diagram in the picture illustrates the division of vascular plants.

The non-vascular plants are divided in turn into Bryophytes and Pterophytes. The Bryophytes are divided into three groups: the liverworts, hornworts and mosses. The vascular plants are also divided into two groups gymnosperms (unprotected seeds) and angiosperms (seeds enclosed within a carpel).  

Angiosperms are further divided into monocots and dicots depending on the number of the cotyledons. These are a significant part of the embryo contained within a seed and the first part to emerge from the soils. Monocots (mono - one/single) as is illustrated by their name have only one whereas dicots two (di - two).
