Question

Read the following statements regarding meristematic cells and select the correct ones.
I. Cell possess the ability to grow and divide
II. Cells have dense cytoplasm with prominent nucleus
III. Well-developed ER and mitochondria are present

I. AND II.
II. AND III
I. AND III.
I., II., AND III.

Answer 1

Hint: Meristematic Cells are those cells which continuously undergo division. During their division, their cytoplasm also gets divided, so they need a thicker cytoplasm and a distinct nucleus. Since these cells are not specialized to perform any particular function hence they do not need any cell organelles.

Complete answer:
To solve the given question, we must be well aware of the plant cells, especially the meristematic cell.

Plants tissues are of two types:
A. Meristematic
B. Permanent

Meristematic cells grow and divide. Since the cytoplasm gets equally distributed, hence the cytoplasm is dense and the nucleus is prominent. Well-developed Endoplasmic Reticulum and Mitochondria are required in those plants which are specialized to perform different functions. Since, the main function of mitochondria is growth hence cell organelles are not required. Permanent cells have lost their ability to multiply. They have become specialized in performing the various functions.

Therefore, the correct answer to the question is option A i.e. I. and II.

Note: Meristematic cells are isodiametric. They have no intercellular spaces and have thin cellulosic walls. The meristematic cells lack vacuoles, endoplasmic reticulum and plastids. Further, they have no reserve food material.
