Question

ratio of pollen grains pollen tetrad and PMC​

Answer 1

Answer:

A single pollen mother cell (PMC) produces pollen tetrad (4 pollens joined together). Thus, pollen tetrad is a single entity.

Answer 2

Answer:

Ratio of pollen tetrad and PMC will be 1:1

Explanation:

• Pollen mother cell(PMC) is a part of hypodermis of pollen sac responsible for formation of male gametophytes called pollen grains.
• Each PMC undergoes meiotic cycle to form 4 microspores which does not separate but instead remain attached with each other by callose.
• These 4 microspores attached together is called tetrad meaning 'group of 4'.
• Thus, one PMC form one tetrad which develops into 4 microspores after dissolution of callose.
