Explanation of winged pollen grains in different plants:
Mustard:
- Winged pollen grains are not present in mustard plants. Mustard plants produce non-winged pollen grains.
Cycas:
- Cycas plants do have winged pollen grains. These plants are gymnosperms and their pollen grains have wings to aid in dispersal by wind.
Pinus:
- Pinus plants, which belong to the gymnosperm group, also have winged pollen grains. The wings help in wind dispersal of pollen for reproduction.
Mango:
- Mango plants do not have winged pollen grains. Mango trees produce pollen grains without wings for pollination by insects.
In conclusion, winged pollen grains are present in Cycas and Pinus plants but not in Mustard and Mango plants. The presence or absence of winged pollen grains is related to the method of pollination and dispersal in different plant species.
