Question

Identify the incorrect statement from the following- (a) cells keep dividing in meristematic zone  (b) meristem produces new cells which are similar in appearance initially but change later © meristematic tissues lack vacuoles (d) lateral meristem act as pro-meristem
/

Finally completed
​

Answer 1

Option d) is incorrect statement

Explanation:

• Meristem is a type of tissue consist of undifferentiated cells . These cells continue to divide before differentiating into specific differentiated cells.
• After a certain time these continuously dividing cell stop cell division and get differentiated and produce cells of different types.
• So, meristem produce new cells which are similar in appearance initially but change later as they differentiated into different cell types.
• Meristematic cells have dense cytoplasm and thin cell wall required for continuous cell division therefor they lack vacuole
• Pro meristem is first formed meristem that give rise primary meristem.
• Where lateral meristem is secondary meristem that originate from primary tissue and involved in secondary growth
• so lateral meristem cannot act as pro meristem.
• So, option d is incorrect statement.
