Meristematic Tissues and Continuous Growth — NEET Biology
🔥 Predicted for NEET 2027How do plants and animals continue to grow all their lives? Do all cells in a plant divide all the time? Do you think cells continue to divide in all plants and animals? Can you tell the name and the location of tissues having cells that divide all their life in higher plants? Do animals have similar meristematic tissues?
Adjacent to a frequently-asked paragraph in the same chapter.
Identify the correct statements regarding mitosis: 1. Mitosis helps maintain the nucleo-cytoplasmic ratio in dividing cells. 2. It helps replace old, injured or worn-out cells. 3. Syncytium formation occurs due to karyokinesis not followed by cytokinesis. 4. Crossing over reduces chromosome number in daughter cells. 5. Continuous growth in plants is due to mitotic divisions in meristematic tissues.
View solution & NCERT explanation
Correct answer: B — 1, 2, 3 and 5 are correct
Mitosis maintains the nucleo‑cytoplasmic ratio because the nucleus and cytoplasm divide equally during each cell division. It replaces old, injured or worn‑out cells by producing genetically identical daughter cells. Syncytium formation results from repeated nuclear divisions not followed by cytokinesis and is not a typical outcome of mitotic cycles. Crossing over occurs only during meiosis and does not occur in mitosis, so statement 4 is incorrect. Meristematic tissues undergo continuous mitotic divisions that enable plant growth.
