Answer:

1. When seeds are planted, they first grow roots. Once these roots take hold, a small plant will begin to emerge and eventually break through the soil. ... As the plant grows and begins to make its own food from nutrients it takes from the soil, it will grow into a larger plant. The seed itself is like a survival package.

2.The spores of seed plants are produced internally, and the megaspores (formed within the ovules) and the microspores are involved in the formation of more complex structures that form the dispersal units, the seeds and pollen grains.

4. There are five main modes of seed dispersal: gravity, wind, ballistic, water, and by animals.

5.Dispersal of seeds is very important for the survival of plant species. If plants grow too closely together, they have to compete for light, water and nutrients from the soil. Seed dispersal allows plants to spread out from a wide area and avoid competing with one another for the same resources.

6.A coconut falls from its mother plant onto the beach. When the tide comes up or there's a swell, the ocean picks up the floating seed. Ocean currents then take the seed to another beach, where it can grow into a coconut palm tree.
