Which process helps plants form new cells?

• A. Respiration
• B. Mitosis
• C. Photosynthesis
• D. Fermentation

Answer: (B)

Forming new cells in plants happens through mitosis, a type of cell division. In mitosis, the cell first copies its genetic material and then divides to produce two genetically identical daughter cells. This process is essential for growth, tissue repair, and development, and in plants it occurs often in meristematic regions like the tips of roots and shoots. After the nucleus splits, cytokinesis finishes the job by dividing the cytoplasm; in plant cells this involves vesicles forming a cell plate that becomes a separating cell wall between the new cells. The other processes listed—respiration, photosynthesis, and fermentation—are about energy production and metabolism, not creating new cells themselves, though they support growth.
