Mother in the context of "Mother church"

Mother Nature (sometimes known as Mother Earth or the Earth Mother) is a personification of nature that focuses on the life-giving and nurturing aspects of nature by embodying it, in the form of a mother or mother goddess.

Parenting or child rearing promotes and supports the physical, cognitive, social, emotional, and educational development from infancy to adulthood. Parenting refers to the intricacies of raising a child and not exclusively for a biological relationship.

The most common caretakers in parenting are the biological parents of the child in question. However, a caretaker may be an older sibling, step-parent, grandparent, legal guardian, aunt, uncle, other family members, or a family friend. Governments and society may also have a role in child-rearing or upbringing. In many cases, orphaned or abandoned children receive parental care from non-parent or non-blood relations. Others may be adopted, raised in foster care, or placed in an orphanage.

Empress dowager (also dowager empress or empress mother; Chinese and Japanese: 皇太后; pinyin: huángtàihòu; rōmaji: Kōtaigō; Korean: 황태후 (皇太后); romaja: Hwang Tae Hu; Vietnamese: Hoàng Thái Hậu (皇太后)) is the English language translation of the title given to the mother or widow of a monarch, especially in regards to Chinese, Japanese, Korean, or Vietnamese monarchs in the Chinese cultural sphere. The term however, is applied well beyond just East Asia.

The title was also given occasionally to another woman of the same generation, while a woman from the previous generation was sometimes given the title of grand empress dowager (Chinese and Japanese: 太皇太后; pinyin: tàihúangtàihòu; rōmaji: Taikōtaigō; Korean: 태황태후 (太皇太后); romaja: Tae Hwang Tae Hu; Vietnamese: Thái Hoàng Thái Hậu (太皇太后)). An empress dowager wielded power over the harem and imperial family. Numerous empress dowagers held regency during the reign of underage emperors. Many of the most prominent empress dowagers also extended their control for long periods after the emperor was old enough to govern. This was a source of political turmoil according to the traditional view of Chinese history.

Mitochondrial DNA (mDNA or mtDNA) is the DNA located in the mitochondria organelles in a eukaryotic cell that converts chemical energy from food into adenosine triphosphate (ATP). Mitochondrial DNA is a small portion of the DNA contained in a eukaryotic cell; most of the DNA is in the cell nucleus, and, in plants and algae, the DNA also is found in plastids, such as chloroplasts. Mitochondrial DNA is responsible for coding of 13 essential subunits of the complex oxidative phosphorylation (OXPHOS) system which has a role in cellular energy conversion.

Human mitochondrial DNA was the first significant part of the human genome to be sequenced. This sequencing revealed that human mtDNA has 16,569 base pairs and encodes 13 proteins. As in other vertebrates, the human mitochondrial genetic code differs slightly from nuclear DNA.

Lactation describes the secretion of milk from the mammary glands in addition to the period of time that a mother lactates to feed her young. The process can occur with all sexually mature female mammals, although it may predate mammals. The process of feeding milk in all female creatures is called nursing, and in humans it is also called breastfeeding. Newborn infants often produce some milk from their own breast tissue, known colloquially as witch's milk.

In most species, lactation is a sign that the female has been pregnant at some point in her life, although in humans and goats, it can happen without pregnancy. Nearly every species of mammal has teats; except for monotremes, egg-laying mammals, which instead release milk through ducts in the abdomen. In only a handful of species of mammals, certain bat species, is milk production a normal male function.

Milk immunity is the protection provided to immune system of an infant via the biologically active components in milk, typically provided by the infant's mother.

A daughter is a female offspring; a girl or a woman in relation to her parents. Daughterhood is the state, condition or quality of being someone's daughter. The male counterpart is a son. Analogously the name is used in several areas to show relations between groups or elements. From biological perspective, a daughter is a first degree relative. The word daughter also has several other connotations attached to it, one of these being used in reference to a female descendant or consanguinity. It can also be used as a term of endearment coming from an elder.

In patriarchal societies, daughters often have different or lesser familial rights than sons. A family may prefer to have sons rather than daughters and subject daughters to female infanticide. In some societies, it is the custom for a daughter to be 'sold' to her husband, who must pay a bride price. The reverse of this custom, where the parents pay the husband a sum of money to compensate for the financial burden of the woman and is known as a dowry. The payment of a dowry can be found in societies where women do not labour outside the home.
