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.
Connective tissue is one of the four types of tissue in traditional classifications (the others being epithelial, muscle, and nervous tissue.) It is largely a category of exclusion rather than one with a precise definition, but all or most tissues in this category are similarly: * Involved in structure and support.eport Abuse. None of the above...it's classified as connective tissue because living blood cells (red blood cells, white blood cells) are found within an extracellular matrix consisting of nonliving tissue. I guess B would be the best answer.
