The Correct Option is A

Solution and Explanation

Bryophytes are land inhabiting or terrestrial plants. They complete their vegetative phase on land but water is necessary for their reproductive phase i.e. for completion of life cycle. So bryophytes are known as amphibians of plant kingdom. Thallophytes have a plant body that is not clearly differentiated into root, stem and leaves. They do not have vascular tissues and so are always aquatic. Pteridophytes are most primitive vascular plants. They have developed vascular tissues and so they were the first vascular plants on land. Tracheophyte includes all vascular plants - pteridophytes, gymnosperms and angiosperms.

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.
