What would be the number of chromosomes in the cells of the aleurone layer in a plant species with 8 chromosomes in its synergids?
- 16
- 24
- 32
- 8
The Correct Option is B
Solution and Explanation
Synergids are characterized by their haploid nature, with a chromosome number represented as n = 8.
Conversely, the aleurone layer exhibits a triploid nature, resulting in the aleurone layer containing '3n' chromosomes.
In this case, '3n' equals '3 x 8,' which means that there are 24 chromosomes present in the aleurone layer.
So, the correct option is (B): 24

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:

Sexual Reproduction in Flowering Plants
Sexual reproduction in flowering plants takes place or happens when the production of a new organism occurs from two parents by making use of their gametes or sex cells. Both sexual and asexual reproduction can be found in plants. Nearly all flowering plants reproduce sexually. Flowers play a captious role in the process as it carries both the male and female reproductive parts commonly known as androecium and gynoecium respectively.
An individual flower comprises the following parts -
- Pedicle
- Calyx
- Petals
- Sepals
- Stamen
- Pistil
- Receptacle
