1. What is the process by which cells divide to form two identical daughter cells?

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.

2. What organelle do plant cells have that functions as storage, waste disposal, and protection?

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.

3. A scientist needs 12 mL of a solution. They have a bottle with 12L in it. Do they have enough?

Correct answer: B

Rationale: 1 liter has 1000 milliliters. To convert from milliliters to liters, the decimal point moves three places to the left. So, the bottle has 12000 mL of solution, which is a lot more than the required 12 mL. Therefore, the scientist has more than what they need. Choice A is incorrect as the bottle has more than the required amount. Choice C is incorrect as the bottle contains significantly more solution than needed. Choice D is incorrect as the scientist does have more than enough solution.

4. Which of the following organelles are responsible for producing cell energy?

Correct answer: A

Rationale: The correct answer is A: Mitochondrion and chloroplast. Mitochondria and chloroplasts are the organelles responsible for producing cell energy through cellular respiration and photosynthesis, respectively. Choice B is incorrect because the nucleus is not involved in energy production. Choice C is incorrect as the nucleus is not an organelle that produces energy. Choice D is incorrect as lysosomes function in digesting waste materials, not in energy production.

5. Which part of the plant produces pollen?

Correct answer: A

Rationale: The anther is the part of the flower that produces pollen. It is located at the tip of the stamen, the male reproductive organ of a flower. The anther contains pollen sacs where pollen grains are produced. The style is the part of the pistil that connects the stigma to the ovary, playing a role in pollen tube growth. The stigma is the part of the pistil that receives pollen during fertilization. The pistil is the female reproductive organ of a flower, consisting of the stigma, style, and ovary, and does not produce pollen.
