ROCKY PLANETS (Mercury-Venus-Earth-Mars-Pluto). The rocky planets are mostly made up of rock and metal. These planets are very heavy and move slowly. They also do not have rings and very few moons. GAS PLANETS (Jupiter-Saturn-Uranus-Neptune). The gas planets are mostly made up of gases (hydrogen and helium).These planets are light for their sizes (just like a big air balloon) and move quickly. They have rings and lots of moons.he gas planets are mostly made up of gases (hydrogen and helium). These planets are light for their sizes (just like a big air balloon) and move quickly.

Plants that live in streams are also referred to as aquatic plants. These plants have adapted to live in water or fully saturated soil. Most aquatic plants are perennials that reproduce by using their flowering parts, also called angiosperms. The leaves of aquatic plants tends to be large and flat to maximize the suns rays.
It is harder for lakes and ponds to support large communities of vegetation because of their great depth. The plants found here normally consist of grasses, and weeds. Sometimes plants like cattails, and lily pads (refer to figure 1) can be found floating in shallow lakes and ponds (W3). Water Lilies: Seed Dispersal: The flower of the water lily (refer to figure 2) makes a fruit that floats in the water and then drops down to the bottom of the body of water.
