In a moss, the sporophyte-
In a moss, the sporophyte-
Updated On: Jun 23, 2024
- Manufactures food for itself as well as for the gametophyte
- is partially parasitic on the gametophyte
- produces gametes that give rise to the gametophyte
- Arises from a spore produced from the gametophyte.
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Mosses like Funaria are bryophytes. They are non-vascular plants. The main plant body is gametophytic (n) which is independent and foliose. It forms major part of the life cycle. The sporophytic 44 phase starts with zygote which divides to form sporogenous tissue that is differentiated into foot, seta and capsule. The sporophytic phase is short lived. The foot absorbs nutrients and provides support to the sporophyte.

Given below are two statements:
Statement I: Transfer RNAs and ribosomal RNA do not interact with mRNA.
Statement II: RNA interference (RNAi) takes place in all eukaryotic organisms as a method of cellular defence.
In the light of the above statements, choose the most appropriate answer from the options given below:- NEET (UG) - 2025
- RNA interference
- Given below are two statements: Statement I: In the RNA world, RNA is considered the first genetic material evolved to carry out essential life processes. RNA acts as a genetic material and also as a catalyst for some important biochemical reactions in living systems. Being reactive, RNA is unstable.
Statement II: DNA evolved from RNA and is a more stable genetic material. Its double helical strands being complementary, resist changes by evolving repair mechanisms. In the light of the above statements, choose the most appropriate answer from the options given below:- NEET (UG) - 2025

- Two gases A and B are filled at the same pressure in separate cylinders with movable pistons of radii \(r_A\) and \(r_B\) respectively. On supplying an equal amount of heat to both the cylinders, their pressures remain constant and their pistons are displaced by 16 cm and 9 cm respectively. If the change in their internal energies is the same, then the ratio \(r_A / r_B\) is:

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.
