Pine cone seeds are produced in the <u>ovules</u> of the <u>female</u> cone.
Pine trees are evergreen coniferous trees with the presence of the characteristic needle like photosynthetic leaves. Pine trees have both the male and female cones on the same tree and are monoecious. The male cones are short lived and fall off after shedding pollen grains. The female cones are long lived and contain the ovules which are fertilized by the pollen to form seeds. Each female cone has spirally arranged scales with two seeds on each scale. On maturity, the cones release the seeds and are dispersed by wind or birds.
The correct answer is Three germ layers. The feature, three germ layers, is only shown by higher invertebrates, as compared to lower invertebrates. The formation of the three germ layers is caused by the morphogenetic movement called Gastrulation.

What I did was I said the plates moved 3 centimeters per year and and times it by 100 million years and you get how far the plates have moved against each other. When they move that far against each other, the land would break and pile up to create mountains. Under the sea, the earth would collide and and create a chain of volcanoes. I got a 4/4 for this question, hope this helps you. Good luck!
