Which among the following produce seeds?

Thallophyta.
B
Bryophyta.

Pteridophyta.
✓
Gymnosperms.

Answer
Correct option: D.
Gymnosperms.
The reproductive organs in the members of Cryptogams $($seedless plants$)$, i.e., thallophyta, bryophyta and pteridophyta are inconspicuous or hidden. They produce naked embryos after fertilisation $($union of male gamete with female gamete$)$ that are called spores. In the case of phanerogams $($seed bearing plants$)$, i.e., the gymnosperms and angiosperms, seeds are produced after fertilisation. They contain embryo along with stored food. The stored food provides nourishment to the developing embryo. Gymmosperms bear naked seeds while the angiosperm bears seeds enclosed in a fruit $($the ovules are inside the ovary$)$.
