Question
An anther with malfunctioning tapetum often fails to produce viable male gametophytes. Give any one reason.
Solution
The tapetum is the innermost layer of a microsporangium, which is found in a cluster of two in each lobe of an anther. The tapetum is responsible for nourishing the pollen grains. Hence, if it malfunctions then the pollen grains will not be provided with sufficient nutrition and will not be able to mature into viable male gametes.
