Identifying Unique Plant Cell Organelles
To answer the question "Which of the following are present only in plant cells?", we need to identify the organelle exclusive to plant cells among the given options. Plant cells possess certain structures not found in animal cells, which distinguish them.
Analysis of Options
- Golgi apparatus: This organelle modifies, sorts, and packages proteins and lipids. It is present in both plant cells and animal cells.
- Nucleus: The nucleus contains the cell's genetic material and controls its activities. It is found in both plant cells and animal cells.
- Plastids: These are organelles unique to plant cells and algae. Examples include chloroplasts (for photosynthesis), chromoplasts, and leucoplasts. Animal cells do not have plastids.
- Mitochondrion: Often called the "powerhouse" of the cell, mitochondria generate ATP through cellular respiration. They are present in virtually all eukaryotic cells, including both plant cells and animal cells.
Conclusion
Based on the analysis, Plastids are the only organelles listed that are exclusively found in plant cells.
