1. Which division among plants has
the simplest organisms?
2. How are pteridophytes different
from the phanerogams?
3. How do gymnosperms and
angiosperms differ from each
other?​

Answer 1

1.Thallophyta has the simplest organisms in plants division. Thallophyta is the lowest group ofplants. This group has the simplest organisms.

2.The reproductive organs ofpteridophytes are not very well developed, and they are therefore called cryptogams or those with hidden reproductive organs. On the other hand, plants. with well differentiated reproductive organs that u]timately make seeds are calledphanerogams.

3.Angiosperms, also called flowering plants, have seeds that are enclosed within an ovary (usually a fruit), whilegymnosperms have no flowers or fruits, and have unenclosed or “naked” seeds on the surface of scales or leaves. Gymnosperm seeds are often configured

Answer 2

Answer:

1. 1 . Thallophyta is the simplest group of The plantae Kingdom as it has low level of organisation
2. Pteridophytes are cryptogams which have very inconscipuous hidden reproductive parts and their body is well differentiated in stems roots and also they have specialised tissue for conduction of water and food .Examples are marsilea ,fern and horse tails . But Phanerogams are plants with well differentiated reproductive organs which ultimately make seeds .As the seeds are the result of sexual reproduction process .This group have further clarification as angiosperms and gymnosperms
