The Correct Option is B

Solution and Explanation

Cycas is a gymnosperm and Adiantum is a pteridophyte

  • Cambium and seeds are absent in pteridophytes whereas vessels are absent in both. 
  • Both Cycas and Adiantum resemble each other in having multi-ciliated sperms.
  • Adiantum known as Maidenhair fern is a pteridophyte that resembles cycas in having motile sperm. 
  • Seeds and cambium are common in gymnosperms and are absent in pteridophytes. 
  • True vessels are absent in both pteridophytes and gymnosperms

Hence the correct option is B - Cycas and adiantum resemble each other in having motile sperms.

Plant Kingdom

The Plant Kingdom comprises all the plants that have some shared characteristics. These are bacteria (prokaryotes), photosynthetic plants, fungi, and several non-photosynthetic plants.

Several features of Kingdom Plantae are as follows:

  • They are stationary. They are static and usually remain in one place only.
  • They have branches that expanded and green leaves due to the presence of chlorophyll.
  • They are an autotrophic mode of nutrition that simply means they prepare their food with the help of water, sunlight and carbon dioxide. It is further known as self-nutrition.
  • They indulge in photosynthesis during the day and therefore more carbon dioxide is needed during the day and at night it is released.
  • They secure their food in the form of starch-like algae.
  • They have an inelastic wall around their cell known as a cell wall comprised of cellulose.
  • There is an absence of the nervous system and excretory system.
  • Reproduction is entirely dependent on air, insects and water. Asexual and vegetative method of reproduction is noticed or detected.
  • The non-photosynthetic plants acquire their food through parasitism, i.e through their host like Indian pipe.
