Question

Geometric growth is seen in

• A. zygote during embryogenesis.
• B. explant in tissue culture.
• C. bacteria in rich nutrient culture.
• D. meristematic cells in root tip.

Answer 1

Answer: (A), (B), (C)

The correct options are
A zygote during embryogenesis.
B explant in tissue culture.
C bacteria in rich nutrient culture.

In geometric growth, the cell count after each divison doubles. Geometric growth is seen in case of zygote during early embryonic development, explant tissues in cell culture and in bacteria multiplying in nutrient rich medium.

Meristematic cells in root and shoot tips show arithmetic growth.
