Meristematic cells are a type of plant cells that possess the ability to grow and divide. These cells are found in the
meristem, which is the region of active cell division in plants. Meristematic cells play a crucial role in plant growth and development. Let's analyze each statement regarding meristematic cells and select the correct ones.
Statement (i): Cells possess the ability to grow and divide.
This statement is
correct. Meristematic cells are undifferentiated cells that have the ability to undergo cell division and give rise to new cells. This continuous division allows for the growth and development of the plant.
Statement (ii): Cells have dense cytoplasm with prominent nucleus.
This statement is
correct. Meristematic cells typically have a dense cytoplasm, which is filled with various organelles including a prominent nucleus. The nucleus contains the genetic material and is involved in cell division and growth.
Statement (iii): Well-developed ER and mitochondria are present.
This statement is
incorrect. Meristematic cells are characterized by their high metabolic activity, but they do not possess well-developed endoplasmic reticulum (ER) and mitochondria. These organelles become more prominent and developed as the cells undergo differentiation and assume specialized functions.
Therefore, the correct statements regarding meristematic cells are:
- (i) Cells possess the ability to grow and divide.
- (ii) Cells have dense cytoplasm with a prominent nucleus.
Hence, the correct answer is option (a) (i) and (ii).
