Spongy tissue is a type of tissue found both in plants and animals.. In plants, it is part of the mesophyll, where it forms a layer next to the palisade cells in the leaf.The spongy mesophyll's function is to allow for the interchange of gases (CO 2) that are needed for photosynthesis.
In biology, tissue is an assembly of similar cells and their extracellular matrix from the same embryonic origin that together carry out a specific function. [1] [2] Tissues occupy a biological organizational level between cells and a complete organ.
A bone is a rigid organ [1] that constitutes part of the skeleton in most vertebrate animals. Bones protect the various other organs of the body, produce red and white blood cells, store minerals, provide structure and support for the body, and enable mobility.

Dense connective tissue, also called dense fibrous tissue, is a type of connective tissue with fibers as its main matrix element. [1] The fibers are mainly composed of type I collagen.
Connective tissue is one of the four primary types of animal tissue, a group of cells that are similar in structure, along with epithelial tissue, muscle tissue, and nervous tissue. [1]
