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.
Within the human body, stem cell niches maintain adult stem cells in a quiescent (inactive) state.
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 tissue that makes up most of your skin is Epithelial tissue.
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.
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.
Within the human body, stem cell niches maintain adult stem cells in a quiescent (inactive) state.
A poorly-differentiated tumor resembles many different tissues. In contract, it's easy to name the tissue type of a well-differentiated tumor.

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.

The tissue that makes up most of your skin is Epithelial tissue.
A tissue is a group of cells of similar appearance and a common function. So yes, animal tissues as well as all tissues consists of uncountable cells.

The hierarchy of living organisms typically consists of several levels: cells, tissues, organs, organ systems, organisms, populations, communities, ecosystems, and the biosphere. At the most basic level, cells are the fundamental units of life, which group together to form tissues. These tissues combine to create organs, which work together in organ systems to support the overall functioning of an organism. Higher levels of organization involve interactions between multiple organisms and their environments, leading to populations, communities, ecosystems, and finally the biosphere, which encompasses all living things on Earth.
