Gametes are delicate single cells. For two plants to cross fertilize, there must be a mechanism for the two gametes to reach each other safely. There must also be a mechanism to disperse their offspring far enough away from the parent so that they do not have to compete with the parent for light, water, and soil minerals. The functions of the flower solve both of these problems.

Plants that use insects or other animals to move pollen from one flower to the next have developed greatly modified flower parts to attract pollinators and to facilitate the movement of pollen from one flower to the insect and from the insect back to the next flower.

(A) Seven ecosystems with foundation species were sampled: coastal (seagrass, blue mussel, cordgrass), freshwater (watermilfoil, water-starwort) and terrestrial (Spanish moss, marram grass).

For example, during the Mesozoic Era, the Age of Dinosaurs, the climate was much warmer and carbon dioxide was abundant in the atmosphere. However, throughout the Cenozoic Era (65 Million years ago to today), the climate has been gradually cooling. This section summarizes some of these major past climate changes and how scientists study past climate change.

Students engage in lab exercises that include flower dissection and explore various fruit types, including seedless varieties and classifications of dry fruits. The significance of seed dispersal mechanisms and genetic diversity through pollination methods is highlighted, along with practical aspects of embryonic development and germination.

Four major adaptations are found in all terrestrial plants: the alternation of generations, a sporangium in which the spores are formed, a gametangium that produces haploid cells, and apical meristem tissue in roots and shoots.

As mentioned above, one of the two sperm cells that were released from the pollen grains and delivered to the ovary via the pollen tube will join the egg to give rise to an embryo, while the other sperm cell will fuse with a structure, found inside of the plant egg, called the polar nucleus giving rise to a nutritive tissue called the endosperm.
