Answer 1

The thallophytes, the bryophytes and the pteridophytes have naked embryos that are called spores.The reproductive organs of plants in all these three groups are very inconspicuous, and they are therefore called cryptogamae, or those with hidden reproductive organs.

Answer 2

Cryptogamae

Explanation:

• A cryptogam is a plant that replicates by spores, without blossoms or seeds. That's the reason cryptogamae is also known as the hidden reproduction.
• Gymnosperm is any vascular plant that repeats by methods for an uncovered seed, or ovule. In contrast to angiosperms, or blooming plants, whose seeds are encased by developing ovaries, or natural products, the seeds of numerous gymnosperms are borne in cones and are not unmistakable until development.  
• Phanerogams are any plant that produces seeds (as opposed to spores).
