Each question is followed by a comprehensive explanation to enhance understanding. Question 1: Cell Structure and Function Which organelle is primarily responsible for energy production in eukaryotic cells? A) Ribosome B) Nucleus C) Mitochondrion D) Golgi apparatus Answer: C) Mitochondrion Explanation: Mitochondria are known as the "powerhouses" of the cell because they generate ATP through cellular respiration, providing energy needed for various cellular processes. Ribosomes synthesize proteins, the nucleus contains genetic material, and the Golgi apparatus modifies and packages proteins and lipids. --- Question 2: Genetics In pea plants, the allele for purple flowers (P) is dominant over the allele for white flowers (p). If two heterozygous plants are crossed, what is the probability that their offspring will have white flowers? A) 25% B) 50% C) 75% D) 100% Answer: A) 25% Explanation: Using a Punnett square: - Parent genotypes: Pp × Pp - Possible gametes: P or p from each parent Punnett square: | | P | p | |-----|---|---| | P | PP| Pp| | p | Pp| pp| - Genotypic ratios: 1 PP : 2 Pp : 1 pp - Phenotypic ratio: 3 purple : 1 white Thus, the probability of white-flowered offspring (pp) is 1 out of 4, or 25%. --- Question 3: Photosynthesis During photosynthesis, which molecule is the primary electron donor in the light-dependent reactions? A) NADPH B) Water C) Carbon dioxide D) Glucose Answer: B) Water Explanation: In the light-dependent reactions, water molecules are split via photolysis, releasing electrons, protons, and oxygen. The electrons from water replenish those lost by chlorophyll molecules, enabling the conversion of light energy into chemical energy. --- Question 4: Ecology Which of the following best describes a keystone species? A) An organism that is the most abundant in its ecosystem B) A species that plays a critical role in maintaining the structure of an ecological community C) An invasive species that disrupts native populations D) A species that is at the top of the food chain Answer: B) A species that plays a critical role in maintaining the structure of an ecological community Explanation: Keystone species have a disproportionately large impact on their ecosystems relative to their abundance. Their presence maintains biodiversity and ecological balance. For example, sea otters control sea urchin populations, preventing kelp forest destruction. --- Question 5: Experimental Design In an experiment testing the effect of fertilizer on plant growth, what is the main purpose of including a control group? A) To ensure the experiment is ethical B) To account for environmental variables that could influence growth C) To increase the sample size D) To test multiple variables simultaneously Answer: B) To account for environmental variables that could influence growth Explanation: A control group provides a baseline, allowing Sat Biology Practice Test With Answers 7 researchers to compare the effects of the fertilizer against plants that did not receive it.
