MCQ
Which of the following events occur immediately after fertilisation in angiosperms?
✅ Correct Answer: D
Endosperm develops before embryo in most cases.
Assertion-Reason
Assertion (A): Seeds can successfully germinate when conditions become favorable.
Reason (R): The micropyle facilitates entry of oxygen and water into the seed during germination.
✅ Correct Answer: A
NCERT confirms seeds germinate under favorable conditions - Assertion true. NCERT states “The micropyle remains as a small pore in the seed coat. This facilitates entry of oxygen and water into the seed during germination.” The Reason explains HOW successful germination occurs through the entry mechanism for essential requirements.
NEET 2025 Pattern
Which of the following statements regarding pollen grains and their properties are correct?
S1. The hard outer layer of pollen grain, exine, is composed of sporopollenin, which is resistant to enzymes, high temperatures, strong acids, and alkalis.
S2. Pollen grains are considered to be rich in nutrients and are marketed as food supplements, particularly in Western countries, for enhancing performance in athletes.
S3. Pollen viability is highly uniform across different plant species and generally persists for several months regardless of environmental conditions.
S4. Pollen of cereals like rice and wheat typically lose viability within approximately 30 minutes of their release.
S5. Pollen grains can be stored for years in liquid nitrogen at -196°C, a method used in pollen banks for crop breeding programmes.
✅ Correct Answer: D
The core concept tested is the characteristics, economic importance, viability, and storage of pollen grains.
S1: The exine, the hard outer layer of the pollen grain, is indeed made of sporopollenin, a highly resistant organic material that can withstand high temperatures, strong acids, and alkali, and no enzyme is known to degrade it. This statement is correct.
S2: Pollen grains are rich in nutrients and are used as food supplements in the form of tablets and syrups in western countries to enhance the performance of athletes and racehorses. This statement is correct.
S3: Pollen viability is highly variable and depends on species and environmental conditions like temperature and humidity, not uniform across species. This statement is incorrect.
S4: In cereals such as rice and wheat, pollen grains lose viability within about 30 minutes of their release. This statement is correct.
S5: Pollen grains of a large number of species can be stored for years in liquid nitrogen (-196°C) as pollen banks for crop breeding programmes. This statement is correct.
Therefore, statements S1, S2, S4, and S5 are correct.
