Comparative Embryology & Embryonic Development

Embryology is the study of fetal development from fertilization to becoming a distinct embryo or species. Comparative embryology is a comparison of fetal development across species. All embryos travel from one cell to a multicellular zygote before differentiation, which is a group of cells called raspberries and a hollow ball called the blastocyst, thus forming […]

What is Cell With a Membrane & Nucleus

The gel-like mucus that fills the space between the extracellular plasma membrane and the central nucleus is called the cytoplasm. All organelles are found in the cytoplasm. The nuclear membrane creates a special environment within the nucleus, in which the thick primary layer is called the nucleus. Cytosol The cytoplasm is divided into transparent liquid […]

Mitochondria: Function, Structure, & Facts

Mitochondria are membrane-bound organelles (mitochondria, singular) that produce most of the chemical energy needed to drive cell biochemical reactions. The chemical energy produced by mitochondria is stored in small molecules called adenosine triphosphate (ATP). Mitochondria have their own small chromosomes. Typically, mitochondrial and mitochondrial DNA is inherited only from the mother. Function Mitochondria are the […]

Fungi: Definition, Types, and Structure

Fungi is a state usually made up of multicellular eukaryotes. They are heterotrophic organisms (cannot make food by themselves) and play an important role in the nutrient cycle in ecosystems. Fungi can breed sexually and botanically, and they also mate with plants and bacteria. However, they are also responsible for some diseases of animals and […]
