The type of reproduction that involves only one parent and no gamete fusion is: MCQ with Answer and Explanation

The type of reproduction that involves only one parent and no gamete fusion is:
A. Sexual reproduction
B. Asexual reproduction
C. Fertilization
D. Cross-pollination
Answer: Option B
Solution (By JKExamLibrary)
Asexual reproduction (binary fission, budding, fragmentation, vegetative propagation) produces genetically identical offspring from a single parent. Sexual reproduction involves gamete fusion. Fertilization is gamete union.

Question #1
The organelle that contains enzymes for the glyoxylate cycle in plants is the:
A. Peroxisome
B. Glyoxysome
C. Chloroplast
D. Mitochondria

Correct Answer: Option B


Explanation:
Glyoxysomes are specialized peroxisomes in oil-storing seeds that contain glyoxylate cycle enzymes, converting lipids to carbohydrates during germination.

Question #2
Consider statements about cell biology: 1. The cell membrane is made of a phospholipid bilayer. 2. Ribosomes are the site of lipid synthesis. 3. The cytoskeleton provides structural support. Which are correct?
A. 2 and 3 only
B. 1 and 3 only
C. 1 and 2 only
D. 1, 2 and 3

Correct Answer: Option B


Explanation:
The cell membrane (plasma membrane) is primarily composed of a phospholipid bilayer with embedded proteins, following the fluid mosaic model. The cytoskeleton is a network of protein filaments (microtubules, microfilaments, intermediate filaments) that provides structural support, shape, and facilitates intracellular transport. Ribosomes are the site of protein synthesis, not lipid synthesis (which occurs in the smooth ER). Thus, statements 1 and 3 are correct.

Question #3
Consider statements about human blood: 1. Red blood cells lack a nucleus at maturity. 2. Platelets are essential for blood clotting. 3. Plasma constitutes about 45% of blood volume. Which are correct?
A. 1 and 2 only
B. 2 and 3 only
C. 1, 2 and 3
D. 1 and 3 only

Correct Answer: Option A


Explanation:
Mature mammalian red blood cells (erythrocytes) are enucleated to maximize space for hemoglobin. Platelets (thrombocytes) are cell fragments crucial for the blood coagulation cascade. Blood plasma, the liquid component, constitutes about 55% of total blood volume, while the formed elements (RBCs, WBCs, platelets) make up the remaining 45%. Thus, statements 1 and 2 are correct.
