Within the human body, stem cell niches maintain adult stem cells in a quiescent (inactive) state.
Stem cells divide through mitosis making two cells known as daughter cells. One daughter cell becomes a stem cell and the other cell differentiates into, or turns into, the tissue the stem cell is meant to maintain.

No, sponges do not have true tissues or organs. They are multicellular organisms but lack differentiated tissues. Instead, they have specialized cell types that work together to carry out various functions, such as feeding and reproduction.
The seven structures of the human body include cells, tissues, organs, organ systems, organisms, populations, and ecosystems. Cells are the basic building blocks of life, which group together to form tissues. Tissues combine to create organs, and organs work together in organ systems to carry out specific functions. Organisms are individual living beings, populations consist of multiple organisms of the same species, and ecosystems involve interactions between living organisms and their environment.
Plant tissues can be differentiated based on their structure, function, and location within the plant. For example, dermal tissues cover and protect the plant, ground tissues provide support and storage, and vascular tissues transport water and nutrients. On a microscopic level, tissues can be distinguished by cell type, arrangement, and presence of specialized structures like xylem vessels or stomata.

The support tissues in the body consist of connective tissues such as tendons, ligaments, and cartilage. These tissues provide structure and support for other tissues and organs in the body.
A poorly-differentiated tumor resembles many different tissues. In contract, it's easy to name the tissue type of a well-differentiated tumor.
Yes, an organ is several tissues working together.

An invasive moderately differentiated squamous cell carcinoma is a skin cancer. When this involves the reticular dermis, the carcinoma involves the connective tissues of the skin.
No, sponges do not have true tissues or organs. They are multicellular organisms but lack differentiated tissues. Instead, they have specialized cell types that work together to carry out various functions, such as feeding and reproduction.

Our Muscle tissues work together to function our movement. They relax, tense, and do other actions. Without them, we would be like an inflated balloon.
No, amoebas are not metazoans. Metazoans refer to multicellular organisms with differentiated tissues and organs, while amoebas are single-celled protists that lack these specialized structures.
