Correct Answer: B

Rationale: The correct answer is B, Gametes. Gametes are the specialized sex cells involved in meiosis, such as sperm and eggs. Somatic cells (
A) are non-reproductive cells found in the body, not involved in meiosis. Zygote (
C) is the result of fertilization, formed when gametes unite. Diploid cells (
D) have two sets of chromosomes, but in meiosis, gametes are produced through a process of cell division that reduces the chromosome number by half to haploid.

Correct Answer: C

Rationale: Correct! Plant cells have vacuoles that serve as storage centers, help in waste disposal by containing and isolating harmful materials, and contribute to protection by storing toxic substances. The other choices are incorrect because the nucleus contains genetic material, mitochondria are responsible for energy production, and ribosomes are involved in protein synthesis.

Correct Answer: B

Rationale: The correct answer is B: Glycolysis. Glycolysis is the initial step in the metabolism of food to cellular energy. During glycolysis, glucose is broken down into pyruvate, generating ATP and NADH.

Choices A, C, and D are incorrect because the Citric Acid Cycle and Electron Transport Chain occur later in cellular respiration, while Photosynthesis is the process by which plants convert light energy into chemical energy.

Correct Answer: B

Rationale: The correct answer is 'B: Cell.' Cells are indeed the fundamental unit of life as they are responsible for all living functions, including growth, reproduction, and maintaining homeostasis. While atoms are the basic building blocks of matter, cells are the smallest structural and functional unit of living organisms.

Choices C and D, tissue and organ respectively, are composed of multiple cells working together and are not considered the basic unit of life.

Correct Answer: A

Rationale: The correct answer is A, Mitosis. Mitosis is the process in which a cell divides to form two identical daughter cells.
Choice B, Meiosis, is a type of cell division that results in four non-identical daughter cells with half the number of chromosomes.
Choice C, Binary Fission, is a form of asexual reproduction used by prokaryotic organisms.
Choice D, Cellular Division, is a general term that encompasses various processes of cell division, but specifically, mitosis refers to the division resulting in two identical daughter cells.
