Question:
Moss peristome takes part in
Moss peristome takes part in
Updated On: Jul 21, 2024
- spore dispersal
- photosynthesis
- protection
- absorption.
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Moss peristome is present in capsule and takes part in spore dispersal. The hygroscopic action of peristomial teeth help in the removal of operculum. The lengthening and shortening of peristomial teeth help in the dispersal of spores. The inner peristome acts as a sieve allowing only a few spores to escape at a time.

- Two cities X and Y are connected by a regular bus service with a bus leaving in either direction every T min. A girl is driving scooty with a speed of 60 km/h in the direction X to Y. She notices that a bus goes past her every 30 minutes in the direction of her motion, and every 10 minutes in the opposite direction. Choose the correct option for the period T of the bus service and the speed (assumed constant) of the buses.

Consider a water tank shown in the figure. It has one wall at \(x = L\) and can be taken to be very wide in the z direction. When filled with a liquid of surface tension \(S\) and density \( \rho \), the liquid surface makes angle \( \theta_0 \) (\( \theta_0 < < 1 \)) with the x-axis at \(x = L\). If \(y(x)\) is the height of the surface then the equation for \(y(x)\) is: (take \(g\) as the acceleration due to gravity)

- The plates of a parallel plate capacitor are separated by d. Two slabs of different dielectric constant \(K_1\) and \(K_2\) with thickness \(d/2\) and \(d/2\) respectively are inserted in the capacitor. Due to this, the capacitance becomes two times larger than when there is nothing between the plates. If \(K_1 = 1.25 K_2\), the value of \(K_2\) 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.
