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.
Blood is a connective tissue vital to our body's survival. In this lesson, we will explore the three functions of blood by delving into red blood cells, white blood cells and platelets-the three individual components that make up blood as a whole.lood is considered a connective tissue because it consists of a non-living fluid in which living cells are suspended. The blood matrix surrounding the cells is known as plasma, which accounts for about 55% of our blood volume.
