Explanation:
A plant with a dominant gametophytic phase alternated by a multicellular sporophytic phase is” Polytrichum/Funaria.”
- Bryophytes have a life cycle where the gametophyte is the dominant phase.
- Hence, every moss plant is a haploid gametophyte.
- The sporophyte generation in mosses is dependent on the gametophyte for nutrition.
- It has a short life span, and it consists of a stalk with a capsule that produces spores.
- While other plants, ferns, and green algae have a dominant sporophytic life cycle, every fern plant is a diploid sporophyte.
To conclude, the right answer to this question is Polytrichum/Funaria.

Concepts Used:
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.
