Unlike other gymnosperms, in which pollination, fertilization, and seed maturation occur within the same year, the pines have an extended reproductive cycle of 14-20 months. (The period elapsed between the appearance of the ovulate cone and the maturation of pine seeds in those cones. Fertilization takes place about 1 year after pollination, and seed maturation takes several additional months). Some seeds are shed as soon as they mature, whereas others remain within the female cones for weeks, months, or even years before being shed.

WHAT IS THE Difference between male and female pine cones?

The pine cones that you are familiar with are probably female pine cones. You probably have never noticed male pine cones because they are much smaller and don't look much like the female pine cones. Male pine cones are much smaller and produce pollen grains. Female pine cones contain the egg. The pollen is carried from the male pine cones to the female pine cones by the wind.


The time between the act of pollination and actual fertilization in the pine is about?

The time between pollination and fertilization in pine trees is typically around 15 months. This allows for the pollen grains to settle on the female cones, germinate, and eventually fertilize the ovules to produce seeds.


Are pine trees sexual?

Yes, pine trees are considered to be sexual organisms because they reproduce sexually through the production of male and female cones that contain sperm and eggs for fertilization. This sexual reproduction allows for genetic variation and diversity among pine tree populations.


How do you make a pine cone?

Pine cones are formed on pine trees when the female cones are fertilized by pollen from male cones. Each scale on the cone contains seeds, which are released when the cone dries out and opens up. The process is part of the reproductive cycle of the pine tree.


Pine pollen is primarily disseminated by?

Pine pollen is primarily disseminated by wind. The lightweight nature of pine pollen allows it to be easily carried by the wind over long distances to reach female pine cones for fertilization.

How locations of female and male cones in the pinus can ensure the success of pollination?

The male gametophyte of pine develops in cluster at the tip of lower branches of the cones tree. The location of staminate cones ensures the success of pollination by cross fertilization.

How the locations of male and female cones in Pinus can ensure the success of pollination?

In Pinus, male cones are typically located closer to the top of the tree while female cones are situated lower down. This spatial separation helps to prevent self-pollination and ensures that pollen carried by the wind is more likely to reach female cones of a different tree, increasing genetic diversity and the success of pollination.

Do Pine trees have seeds?

Yes there are seeds in their female cones


What makes a male comes?

Male cones are reproductive structures found in gymnosperms, such as pine trees. They produce pollen grains containing male gametes that are carried by wind to female cones for fertilization. The male cones typically release their pollen in large quantities to increase the chances of successful pollination.


What are the seeds of a Christmas trees or pine trees called?

Pine trees have cones. There are male cones, which are smaller (about 1-5 cm), and female cones, which are larger (3-60 cm). The male cones contain pollen. The female cones have ovules, which become seeds when fertilized by pollen from a male cone.


What does a pine seed consists of?

pine cones


Are there male and female pine cones?

ALL pine trees are cone-bearing -that's where the pine-nuts come from. AND that is WHY they are classified as coniferous.(Coniferous means cone bearing.)


Why are there two kinds of cones on the same pine tree?

More than likely what you are seeing are male and female pine cones which sometimes look different even if they are the same species.


What is found on a pine tree?

Roots, trunk, branches, twigs , needles and cones.


Do the long leaf pine make seeds?

Yes, they do make seeds in their female cones.
