The Correct Option is A

Solution and Explanation

Bryophytes and algae are both autotrophic, plant body thallus like and devoid of vascular tissues. Instead of roots, rhizoids are present for attachment and absorption purpose. Both algae and bryophytes have motile sperms and need water for fertilization. But bryophytes can be separated from algae because archegonium originated for the first time in bryophytes in plant kingdom. It is a flask shaped structure with swollen base called venter and upper elongated neck. The venter contains a venter canal cell and an egg cell. It is surrounded by one celled thick sterile jacket layer. In algae sex organs are non-jacketed and unicellular.

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.
