Question

2 a scientist discovers a plant species whose stem has become weak due to a disease. the leaves begin to droop, and water movement slows. which conclusion best explains how this disease affects the plant in a way similar to how a damaged skeleton would affect an animal? a both would lose the ability to make food. b both would immediately stop growing and die. c both would become unable to sense their surroundings. d both would struggle to support themselves and move important materials.

Explanation:

A plant's stem provides structural support (like a skeleton in an animal) and helps in transporting water (an important material). When the stem is weak (due to disease), support is reduced (leaves droop) and water movement (an important material transport) slows. Similarly, a damaged animal skeleton affects support (ability to stand, etc.) and can impact movement of substances (e.g., if blood - vessel - containing bones are damaged, it can affect blood (a material) circulation in some cases).

• Option A: A plant makes food in leaves (photosynthesis). A damaged stem (or skeleton) doesn't directly relate to food - making ability.
• Option B: "Immediately stop growing and die" is an over - exaggeration. The plant (or animal) may have some compensatory mechanisms or may decline over time, not die immediately.
• Option C: Sensing surroundings is more related to sensory organs (in animals) or sensory cells (in plants, like in roots for gravity sensing) rather than the stem (or skeleton).

Answer:

D. Both would struggle to support themselves and move important materials.
