Differences Between Fungi and Animals. Some fungi are single-celled organisms, such as the yeasts. All metazoans, on the other hand, have multiple cells. Even the simplest animal, the sponge, consists of many cells specialized for different tasks.any fungi are superficially plant-like organisms. They grow visible structures that resemble plants or plant parts. On a microscopic level, plants and fungi both have cell walls, a feature that metazoan (animal) cells lack.
Blood is considered a connective tissue for two basic reasons: (1) embryologically, it has the same origin (mesodermal) as do the other connective tissue types and (2) blood connects the body systems together bringing the needed oxygen, nutrients, hormones and other signaling molecules, and removing the wastes.lood is considered a connective tissue for two basic reasons: (1) embryologically, it has the same origin (mesodermal) as do the other connective tissue types and (2) blood connects the body systems together bringing the needed oxygen, nutrients, hormones and other signaling molecules, and removing the wastes.
Nutrients such as oxygen and the likes are transported all throughout the different part of the body through the blood vessels (composed of arteries, arterioles, capillaries, venules and veins). Many scientists believe that blood is a specialized form of connective tissue.The reason is because of its origin in the bones and the presence of fibers in the form of fibrinogen. Not all liquids can be a connective tissue.The only reason why blood is considered that way is due to the fact that is has a concentration of âground substances, like calcium, minerals and phosphorus in its extra-cellular matrix.he Fibrous connective tissue is found in ligaments and tendons in the body. It is composed of closely packed collagenous fibers. There is also the special connective tissue and blood is among these âspecialized tissues,.
