Question

Cycas is classified as a gymnosperms due to its

• A. Motile sperms
• B. Fruit formation
• C. Naked ovule
• D. Phycnoxylic wood

Answer 1

The correct option is C Naked ovule

• Gymnosperms are the naked seed-bearing plants. A naked seed means that the ovules are not completely enclosed by sporophytic tissue at the time of fertilization.
• Most of the seed plants have pollen, which contains and transports the sperm to fertilize the egg.
• As pollen is resistant to desiccation, the sperm can be transported between plants across large distances without drying up.
• The gymnosperms (naked seed plants) consists of four phyla. These are conifers, cycads, gingkoes, and gnetophytes. Cycads produce pollen, but the sperm still swims down the pollen tube using flagella.
• As it also has a naked seed, it is classified as a gymnosperm.
  Hence, option C is correct.
