Question

Nonflowering plants are called as
A.Cryptogams
B.Angiosperms
C.Phanerogams
D.Gymnosperms

Answer 1

Hint: Some of the plants are known to not produce flowers or seeds. Instead of seeds, plants such as ferns and mosses are considered non-flowering plants and contain spores. There is also another group called Fungi, which includes mushrooms, which also replicate by spores.

Complete answer:
Flowering plants grow flowers and multiply, or create more plants like them, using seeds. Non-flowering plants do not grow flowers and use either seeds or spores to grow more plants just like them, which are very tiny parts of a plant that can be used to replicate. Due to the way they reproduce, non-flowering plants are classified into two major classes. One group, which reproduces itself from seeds, is called gymnosperm, while the other group reproduces from spores.
A cryptogam is a plant that without flowers or seeds, reproduces by spores. Cryptogam means secret reproduction, referring to the fact that no seed is produced, so the non-seed bearing plants are represented by cryptogams. Other names are also sometimes used, such as "thallophytes", "lower plants" and "spore plants" As a group, cryptogams are the opposite of the seed plants of Phanerogamae or Spermatophyta. Algae, lichens, mosses and ferns are the best known classes of cryptogams, but they also include non-photosynthetic species typically categorized as plants, such as fungi, slime molds, and bacteria.

Hence, the correct answer is option (A)

Note: The biggest non-flowering plants are the redwoods. Amongst other plants, the highest. Some plants' spores are lightweight. They are conveniently spread by air.
