Which one of the following is not a characteristic of plant cells in the phase of elongation ?
Options
- ANew cell wall deposition
- BCell enlargement
- CIncreased vacuolation
- DLarge conspicuous nuclei
Correct answer
D. Large conspicuous nuclei
Step-by-step solution
The period of growth is generally divided into three phases: meristematic, elongation, and maturation.
The cells in the meristematic phase are rich in protoplasm and possess large conspicuous nuclei. Their cell walls are primary in nature, thin, and cellulosic with abundant plasmodesmatal connections.
The cells in the phase of elongation are characterised by increased vacuolation, cell enlargement, and new cell wall deposition.
Therefore, large conspicuous nuclei are a characteristic of meristematic cells, not cells in the phase of elongation.
Answer: Large conspicuous nuclei
