Final answer:
Male cones in the Pine Family Pinaceae are found on lower branches while female cones are located on upper branches, promoting cross-pollination and reducing the chances of self-pollination.
Step-by-step explanation:
In the Pine Family Pinaceae, male cones are located at the lower branches, and female cones are located at the upper branches
The male cones, which are usually smaller, release pollen that gets carried by the wind to the female cones. This arrangement facilitates cross-pollination by making it less likely for a gymnosperm to self-pollinate, since gravity helps pollen travel from the male to the female cones. Additionally, positioning the female cones higher up ensures they are more exposed to the wind, thereby increasing the chances of successful pollination from male cones on other trees. Thus, the correct answer to the student's question is a) Lower branches for male cones, upper branches for female cones.
