Identify the asexual reproductive structure associated with Penicillium:
- Zoospores
- Conidia
- Gemmules
- Buds
The Correct Option is B
Solution and Explanation
The asexual reproductive structure associated with Penicillium is conidia. Penicillium is a genus of >fungi known for reproducing asexually through conidia formation. Conidia are non-motile spores that detach from the parent organism and can develop into a new individual under suitable environmental conditions. The process involves the following steps:
- Conidiophore Formation: Specialized structures called conidiophores grow upward from the mycelium.
- Conidia Development: At the tip of conidiophores, conidia are produced via mitotic division.
- Dispersal and Germination: Conidia are released into the environment, where they can germinate to form new mycelium upon finding favorable conditions.
While other structures like zoospores, gemmules, and buds are associated with asexual reproduction in other organisms, conidia are specifically linked to Penicillium.

- Asexual reproduction involves a single parent to produce offspring without the formation of gametes. It occurs by the following ways: Fission, Budding, Fragmentation, Spore formation and Regeneration. In one of the methods like regeneration, Planaria A is cut horizontally into three pieces – L, M and N and Planaria B is cut vertically into two equal halves – O and P.
(a) Which of the cut pieces of the two Planaria could regenerate to form a complete organism?
(b) Give an example of another organism which follows the same mode of reproduction as Planaria.

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:

Asexual Reproduction
The mode of reproduction in which a new offspring is produced by a single parent is known as asexual reproduction. The new individuals produced are genetically and physically identical to each other, i.e., they are the clones of their parents.
Features of Asexual Reproduction:
- Only single parents are involved.
- The fertilization or gamete formation cannot take place.
- This process of reproduction occurs in a very short time.
- The organisms multiply and grow rapidly.
- In this offspring produced is genetically similar.
