Question

Special feature of dividing cells is

• A. Large lacuma
• B. Thick cell walls
• C. Dense cytoplasm devoid of lacuna
• D. Large intercellular spaces

Answer 1

The correct option is C Dense cytoplasm devoid of lacuna

• The continuously dividing undifferentiated cells are called meristematic cells.
  
• They form different meristematic tissues in plants- apical meristematic tissues, intercalary meristematic tissues and latyeral meristematic tissues.

The characteristics of these cells are:-

1)The cells are isodiametric with thin cellulosic cell walls with no secondary cell wall.

2) They divide rapidly hence, there is no stored food in these cells.

3) They are compactly arranged cells with no intercellular spaces.

4) They have a dense cytoplasm with a prominent nucleus and no lacuna.

5) Endoplasmic reticulum and mitochondria are not fully developed in these cells.

6) They are the most metabolically active cells.

So, the correct answer is 'Dense cytoplasm devoid of lacuna'.
