Place the following names of tissues in the appropriate tissue category. Epithelial Tissue is one of the four types of tissue (epithelial, muscular, connective, and nervous) in animals which consists of closely aggregated polyhedral cells adhering firmly to one another, forming cellular sheets that line the interior of hollow organs and cover the body surface. These membranes line the coelomic cavities of the body, that is, those cavities that do not open to the outside, and they cover the organs located within those cavities. Parenchyma Collenchyma Sclerenchyma Parenchyma: Parenchyma is a type of permanent tissue.

While all animals can generally be considered to contain the four tissue types, the manifestation of these tissues can differ depending on the type of organism. Different cell types comprise each tissue type, and the structure of each cell type influences the function of the tissue it comprises. Sclerenchyma. Animal tissues are grouped into four basic types: connective, muscle, nervous, and epithelial. A tissue membrane is a thin layer or sheet of cells that covers the outside of the body (for example, skin), the organs (for example, pericardium), internal passageways that lead to the exterior of the body (for example, abdominal mesenteries), and the lining of the moveable joint cavities. 3.

Permanent tissue provides support and structure for a plant, helps manufacture glucose, and stores water and nutrients (and sometimes air). After fertilization the zygote gives rise to rapid mitotic cycles, generating many cells to form the embryo. Each germ layer is identified by its relative position: ectoderm (ecto– = “outer”), mesoderm (meso– = “middle”), and endoderm (endo– = “inner”). they are made up of only one type of cell.
