Answer 2

Answer:

Yes, this given statement is true.

Gymnosperms represent the group of plants considered to be more advanced than pteridophytes but more primitive than angiosperms.

Explanation:

Gymnosperms represent an advanced group than Pteridophytes and this critical distinction is due to the natural surroundings where they are grown.

How they are more advanced than Pteridophytes?

• Pteridophytes are the first vascular cryptogams adjusted to earthly conditions which are clammy and obscure while Gymnosperms are the most primitive seed plants completely adjusted to earthbound conditions.

• Gymnosperms possess an advanced root system and are made up of well-developed vascular tissues, whereas pteridophytes are divided into root systems, stalks, and leaflets.

• In pteridophytes, both microspores and megaspores are released from their respective sporangia, while in the case of gymnosperms, megaspore is permanently retained.
• Pteridophytes lack pollination and seeds- the main factor of evolution. While gymnosperms possess pollination and are viewed as naked seeded plants on further developed.

• Pteridophytes require an aquatic medium for fertilization while gymnosperms don't need it.

How they are less primitive than Angiosperms?

• The angiosperms are seed-bearing plants whose seeds are found inside an ovary inside a fruit. While in the gymnosperms seeds are exposed and not enclosed in an ovule.

• The angiosperms are those plants that have triploid(3n) tissues while the gymnosperms have haploid(n).

• The leaves of the angiosperms are flat while those of the gymnosperms are cone-bearing, needle-like.

• The gymnosperms are known as softwood as they can last during the winter while the angiosperms are known as hardwood and usually change colour seasonally.

• Flowering plants can survive in a greater variety of habitats than gymnosperms.

• Angiosperms mature more quickly than gymnosperms and produce greater numbers of seeds.
• The woody tissues of angiosperms are also more complex and specialized than that of gymnosperms.

Therefore, Gymnosperms are the group of plants considered to be more advanced than pteridophytes but primitive than angiosperms, justified.
