The question asks to identify the primary site of photosynthesis in a plant. Photosynthesis is the process by which green plants convert light energy into chemical energy, producing glucose and oxygen. This process requires chlorophyll, which is abundant in specific parts of the plant.
Correct Option: C) Leaf
The question asks to identify an example of a saprotroph from the given options. A saprotroph is an organism that obtains its nutrients by feeding on dead or decaying organic matter. We need to evaluate each option based on its mode of nutrition.
C) Fungi are classic examples of saprotrophs, obtaining nutrients by decomposing dead organic matter.
The question asks about the gas released during photosynthesis. To answer this, we need to recall the overall chemical equation for photosynthesis and identify its products.
Correct Option: B) Oxygen is the gas released during photosynthesis, which is vital for the respiration of most living organisms on Earth.
The question asks to identify the substance that indicates photosynthesis in leaves. Photosynthesis is the process by which green plants convert light energy into chemical energy, producing sugars. We need to determine which of the given options is a direct or immediate product of photosynthesis that can be easily detected in leaves.
C) Starch — Starch is the storage form of glucose in plants. When photosynthesis occurs, glucose is produced, and any excess is converted into starch for storage. Therefore, the presence of starch in a leaf indicates that photosynthesis has taken place. This is why the iodine test is commonly used to demonstrate photosynthesis in laboratory experiments.
This question asks about the primary function of "vessels" in plants. In botany, the term "vessels" typically refers to the vascular tissues responsible for transport within the plant. Understanding the roles of xylem and phloem is key to answering this question.
Correct Option: B) Transporting water and minerals
The question asks to identify the process in plants that converts solar energy into chemical energy. We need to evaluate each option based on its primary function in plant physiology.
C) Photosynthesis — Photosynthesis is the fundamental process in plants where light energy from the sun is captured and converted into chemical energy, stored in organic compounds like glucose. This is precisely what the question describes.
