Wind<\/strong><\/p>\n<p>Pine trees are wind-pollinated, which means that the pollen grains are carried to the female cones by the wind. The pollen grains are produced in the male cones, which are located at the top of the tree. The female cones are located at the base of the tree. When the pollen grains are mature, they are released from the male cones and carried by the wind to the female cones. The pollen grains land on the sticky stigma of the female cone, and they germinate and grow a pollen tube down into the ovule. The sperm cells in the pollen tube fertilize the egg cell in the ovule, and a seed is formed.<\/p>\n<p>The other options are incorrect because:<\/p>\n<ul>\n<li>Option A is incorrect because the pollen tube is not what carries the pollen grains to the female cone. The pollen tube is a structure that grows from the pollen grain down into the ovule.<\/li>\n<li>Option C is incorrect because insects do not pollinate pine trees.<\/li>\n<li>Option D is incorrect because animals do not pollinate pine trees.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>[amp_mcq option1=&#8221;Pollen tube&#8221;
