Which one of the following terms is correctly matched with their definition in Pinus ?
1 Monoecious - Male (microsporangiate) and female (megasporangiate) cones are produced on same plant.
2 Monoecious - Male and female sporophylls borne on same strobilus.
3 Dioecious - Male and female cones are produced on different plants.
4 Monoecious - Micro and megasporocarp develop on same plant.
Explanation:
Monoecious is a plant species in which male (microsporangiate) and female (megasporangiate) organs are found on the same plant (for example pinus). Dioecious plant is a plant species in which male and female organs appear on separate individuals.
