Photosynthesis In Higher Plants

To solve the problem, we need to identify the cell organelle in a plant cell that participates in photosynthesis.

1. Understanding Photosynthesis:
Photosynthesis is the process by which plants convert light energy into chemical energy, using carbon dioxide and water to produce glucose and oxygen. This process occurs in plant cells in a specific organelle.

2. Evaluating the Options:
- Option (A): Mitochondria – Mitochondria are involved in cellular respiration, not in photosynthesis.
- Option (B): Chloroplast – Chloroplasts contain chlorophyll, which absorbs light energy and is the site of photosynthesis.
- Option (C): Golgi complex – The Golgi apparatus is involved in processing and packaging proteins, not in photosynthesis.
- Option (D): Endoplasmic reticulum – The ER is involved in protein synthesis and transport, not in photosynthesis.

3. Conclusion:
The cell organelle responsible for photosynthesis in plant cells is the chloroplast.

Final Answer:
The correct answer is option (B): Chloroplast.

To solve the problem, we need to identify the term used for a fern leaf that produces spores.

1. Understanding Fern Reproduction:
Ferns are vascular plants that reproduce through spores rather than seeds. The process of spore production is called sporogenesis, and it occurs on specialized structures.

2. Key Terms Related to Spore Production:
- Sporangium This is the structure where spores are actually produced. It is a small, capsule-like structure that contains spores.
- Sporangiophore: This is the stalk or support structure that holds the sporangia.
- Sporophyll: This is the leaf-like structure of a fern that bears sporangia. It is the part of the plant responsible for producing spores.
- Megasporangium: This term refers to a larger sporangium that produces megaspores (female spores), but it is not specific to ferns.

3. Identifying the Correct Term:
In ferns, the leaf that produces spores is specifically called a sporophyll. It is the leaf-like structure that bears sporangia, which in turn produce spores.

4. Conclusion:
The correct answer is (C) Sporophyll.
