Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Male cones produce ovules.
A
True
B
False
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Male pine cones produce pollen, which is like a powder. The male cones release their pollen, which is carried around the air by blowing wind, and hopefully to another female pine cone on a different pine tree. If the pollen reaches a female pine cone, this process is called pollination.

Detailed explanation-2: -Pine cones can stay on tree for more than 10 years before dropping to the ground. All conifers produce male and female cones.

Detailed explanation-3: -Male cones give rise to microspores, which produce pollen grains, while female cones give rise to megaspores, which produce ovules.

Detailed explanation-4: -Pollen cones produce the male gametophytes, also called pollen grains. Seed cones produce female gametophytes and are generally larger than pollen cones. Female gametophytes develop in two ovules located near the base of each scale. The gymnosperm life cycle typically takes two years to complete.
