A microscopic view of a Scots pine tree (. An organism is comprised of tissues, which are made up of individual cells. The nucleus pulposus is derived from the notochord. There are four basic kinds of tissue in the body: epithelium; connective tissues including adipose tissue, blood, bone, and cartilage; muscle tissue; and nerve tissue. But I suspect it the other way, any idea what it may be? Organs are then formed by the functional grouping together of multiple tissues. In vascular plants, such as angiosperms and gymnosperms, cell division takes place almost exclusively in specific tissues known as meristems. A collection of similar cells and the intercellular substances surrounding them. A form of loose connective tissue consisting of fibroblasts in a matrix of tissue fluid and collagen and elastin fibers. Endometriosis happens when the endometrium, tissue that usually lines the inside of your uterus, grows outside it. It’s made up mostly of fat cells and connective tissue. Question 2 Write the different types of tissue in plants? Connective tissues are made up of two proteins: collagen and elastin. They contribute to improved hygiene, comfort and convenience in our society. Any tissue that arises from the fertilization of an ovum and has not become differentiated or specialized.

This is Daron, 20/m. Instead bryophytes absorb water and nutrients directly through leaflike and stemlike structures or through cells comprising the gametophyte body. There are two general types of muscle: striated muscle, which moves the skeleton and is under voluntary control; and smooth muscle, which surrounds the walls of many internal organs and cannot normally be controlled voluntarily. Connective tissue connects, supports, binds, and separates organs and tissues, forming a framework to support body tissues and organs, for structural and metabolic purposes. The ground tissues, which comprise the remaining plant matter, include various support, storage, and photosynthetic tissues. In vertebrates, most endocrine functions are isolated in specialized glands, several of which are derived from nervous tissue. a group or layer of similarly specialized cells that together perform certain special functions. Secondary, or lateral, meristems, which are found in all woody plants and in some herbaceous ones, consist of the vascular cambium and the cork cambium.
