Question 1

Which of the following plant groups is known as the 'Amphibians of the Plant Kingdom'?

Accepted Answer

Bryophyta. Bryophytes are called amphibians because they live on land but require water for sexual reproduction. They lack true vascular tissues like xylem and phloem for water transport. Mosses and liverworts are common examples of this group.

Question 2

Plants that do not have a well-differentiated body design belong to which group?

Accepted Answer

Thallophyta. Thallophyta includes plants with a simple body structure called a thallus that lacks roots or stems. Algae are the primary representatives of this division in the plant kingdom. These plants are predominantly aquatic in nature.

Question 3

Which group represents the first terrestrial plants to possess vascular tissues?

Accepted Answer

Pteridophyta. Pteridophytes are the first land plants to develop xylem and phloem for conducting water and minerals. They reproduce via spores rather than seeds and do not produce flowers. Ferns and horsetails are well-known members of this category.

Question 4

What is the characteristic feature of Gymnosperms regarding their seeds?

Accepted Answer

Naked seeds. Gymnosperms produce seeds that are not enclosed within a fruit or an ovary. The term itself is derived from Greek words meaning 'naked' and 'seed'. Pine, Cedar, and Cycas are typical examples of gymnosperms.

Question 5

Flowering plants are scientifically classified under which division?

Accepted Answer

Angiosperms. Angiosperms are seed-bearing plants where the seeds develop inside an organ which later becomes a fruit. They are the most diverse and widespread group of plants on Earth today. These plants undergo a unique process known as double fertilization.
