Define apical meristem

The region in apical meristem develps into

Mention the function of apical meristem.

Identify the correct order In vitro culture Organogenesis Apical meristem Cultures are maintained at 24 +- 1^@C

Explain the apical cell theory of root apical meristem.

Distinguish the apical meristem from lateral meristem.

One single maize root apical meristem can give rise to __________ new cells per hour.

Select the option that correctly identifies the labellings A, B and C in the given figure showing section of root apical meristem.

Assertion (A) : Growth is measurable. Reason ( R) : At a cellular level, growth simply means in the amount of protoplasm. One single maize root apical meristem can give rise to more than 17,500 new cells / hour, it is in terms of increase in cell number and cells in the watermelon can increase in size upto 3,50,000, here growth is measured in terms of size of the cells. Therefore Growth is measured in terms of increase in cell number, area, volume, lenght etc.
