Compound Microscope Parts A high power or compound microscope achieves higher levels of magnification than a stereo or low power microscope. It is used to view smaller specimens such as cell structures which cannot be seen at lower levels of magnification. Essentially‚ a compound microscope consists of structural and optical components. However‚ within these two basic systems‚ there are some essential components that every microscopist should know and understand. These key microscope parts are illustrated

There are more to aquatic plants than just floating on the surface of water. Aquatic plants are plants that can adapt and live in a freshwater environment. They are sometimes called hydrophytes. These include plants that live in fresh wetlands‚ swamps‚ ponds‚ lakes‚ and marshes. This type of plant actually serves two important functions. First‚ they help oxygenate water (2006) and they provide nutrients and food for some fishes (Tappin‚ 2003). There are many types of aquatic plants including rooted

This East Texas Lake also has a variety of cover for anglers to fish including flooded timber‚ hydrilla and lily-pads. Some of the best winter time bass fishing is located on the northern end of the lake. Anglers can pursue spawning fish

Fixed 1. A thin cuticle. Cuticles primarily discourage water loss; thus most hydrophytes have no need for cuticles. 2. Stomata that are open most of time because water is abundant and therefore there is no need for it to be retained in the plant. This means that guard cells on the stomata are generally inactive. 3. An increased number of stomata‚ that can be on either side of leaves. 4. A less rigid structure: water pressure supports them. 5. Flat leaves on surface plants for
