The type of asexual reproduction in yeast where a small outgrowth develops into a new individual is: MCQ with Answer and Explanation

The type of asexual reproduction in yeast where a small outgrowth develops into a new individual is:
A. Spore formation
B. Fragmentation
C. Binary fission
D. Budding
Answer: Option D
Solution (By JKSSB Mock Tests)
Budding is an asymmetric division where a new yeast cell forms as a small bud on the parent, eventually pinching off. Binary fission is symmetric splitting (bacteria), fragmentation is breaking into pieces, spore formation involves spores. Budding can occur in some hydra as well.

Question #1
Which of the following tissues provides mechanical strength and flexibility to plant organs?
A. Parenchyma
B. Xylem
C. Sclerenchyma
D. Collenchyma

Correct Answer: Option D


Explanation:
Collenchyma is a simple permanent tissue with living cells, unevenly thickened primary cell walls (cellulose and pectin), providing mechanical support and flexibility, especially in young stems and leaf petioles. Parenchyma is for storage and metabolism, sclerenchyma is dead, rigid with lignified walls, xylem conducts water.

Question #2
Which of the following is a correct statement about biofertilizers?
A. They are living organisms that enrich soil nutrient content.
B. They are toxic to soil organisms.
C. They are synthetic growth regulators.
D. They are chemical fertilizers that enhance crop yield.

Correct Answer: Option A


Explanation:
Biofertilizers contain living microorganisms like bacteria, cyanobacteria, and fungi that increase nutrient availability (e.g., nitrogen fixation, phosphorus solubilization) for plants. They are eco-friendly and sustainable. Chemical fertilizers are synthetic inorganic salts. Biopesticides control pests. Examples: Rhizobium, Azotobacter, mycorrhiza. Biofertilizers improve soil health without chemical residue.

Question #3
Consider statements about Mendel's laws: 1. The Law of Segregation applies to alleles of a single gene. 2. The Law of Independent Assortment applies to genes on the same chromosome. 3. Mendel worked on pea plants. Which are correct?
A. 1 and 3 only
B. 2 and 3 only
C. 1 and 2 only
D. 1, 2 and 3

Correct Answer: Option A


Explanation:
Mendel's Law of Segregation states that allele pairs separate during gamete formation, applying to a single gene. His Law of Independent Assortment applies to genes located on different (non-homologous) chromosomes, not those linked on the same chromosome. Mendel conducted his pioneering genetic experiments on the garden pea, Pisum sativum. Thus, statements 1 and 3 are correct.
