In which one pair both the plants can be vegetatively propagated by leaf pieces ?
- Bryophyllum and Kalanchoe
- Chrysanthemum and Agave
- Agave and Kalanchoe
- Asparagus and Bryophyllum
The Correct Option is A
Solution and Explanation
Both Bryophyllum and Kalanchoe are succulent plants that can produce new plants from individual leaves, making them suitable for vegetative propagation through leaf cuttings.
So, the correct option is (A): Bryophyllum and Kalanchoe

- An oxygen cylinder of volume 30 litre has 18.20 moles of oxygen. After some oxygen is withdrawn from the cylinder, its gauge pressure drops to 11 atmospheric pressure at temperature \(27^\circ\)C. The mass of the oxygen withdrawn from the cylinder is nearly equal to: [Given, \(R = \frac{100}{12} \text{ J mol}^{-1} \text{K}^{-1}\), and molecular mass of \(O_2 = 32 \text{ g/mol}\), 1 atm pressure = \(1.01 \times 10^5 \text{ N/m}^2\)]

- Given below are two statements:
Statement I: Fig fruit is a non-vegetarian fruit as it has enclosed fig wasps in it.
Statement II: Fig wasp and fig tree exhibit a mutual relationship as the fig wasp completes its life cycle in the fig fruit and the fig fruit gets pollinated by the fig wasp. - A wire of resistance \(R\) is cut into 8 equal pieces. From these pieces, two equivalent resistances are made by adding four of these together in parallel. Then these two are added in series. The net effective resistance of the combination is:

Three identical heat conducting rods are connected in series as shown in the figure. The rods on the sides have thermal conductivity 2K while that in the middle has thermal conductivity K. The left end of the combination is maintained at temperature 3T and the right end at T. The rods are thermally insulated from outside. In steady state, temperature at the left junction is \(T_1\) and that at the right junction is \(T_2\). The ratio \(T_1 / T_2\) is

Concepts Used:
Reproduction
The term reproduction is a biological process that means to reproduce. It is a process by which an organism reproduces an offspring that is biologically similar or identical to its parents. Reproduction accredits and ensures the continuity of species, generation after generation, and is the main character of life on earth.
Types of Reproduction:
There are two types of reproduction such as:
Asexual Reproduction:
It is the production an offspring by a single parent beyond the formation and fusion of gametes. The young one obtains all its genes from one parent, so are identical.
Sexual Reproduction:
Sexual reproduction is mostly biparental, includes the formation of meiosis gamete usually fertilization also, instigates genetic variation in the offspring, and plays a role in the evolution of species, found in higher plants and animals.
