Definition: Relating to a type of gland that releases its secretions by breaking down its own cells, which then become part of the secretion.

Example: The holocrine glands in the skin produce oils that help keep the skin moisturized.

Definition: A complete and active enzyme that is made up of a protein part and a non-protein part, which is necessary for its function.

Example: The holoenzyme is essential for the biochemical reactions in the cell.

Definition: A type of sexual reproduction where the reproductive cells are the same size and shape as the body cells.

Example: In some species, hologamy allows for reproduction without the need for different types of gametes.

Definition: A three-dimensional image created using light patterns, often produced by lasers, that can be viewed from different angles.

Example: The museum displayed a stunning hologram of a dinosaur that seemed to move as you walked around it.

Definition: This word describes a type of crystal that has all the necessary flat surfaces to show complete symmetry in its structure.

Example: The mineral was classified as holohedral due to its perfectly symmetrical crystal faces.

Definition: A type of development in certain insects where they undergo a complete transformation from egg to larva to pupa and finally to adult.

Example: Butterflies and beetles are examples of insects that experience holometabolism during their life cycle.

Definition: Describing an organism that undergoes a complete transformation during its life cycle, including distinct stages such as egg, larva, pupa, and adult.

Example: Butterflies are holometabolous insects, going through a complete metamorphosis from caterpillar to adult.

Definition: A single specimen or illustration that is used as the standard for naming a species or subspecies.

Example: The scientist examined the holotype to ensure accurate classification of the new species.

Definition: A short segment of DNA that is important for the development and formation of body structures in many living organisms.

Example: The homeobox is crucial for the proper development of the embryo in various species.

Definition: Relating to a type of genetic change that affects the development of an organism, often causing significant alterations in the structure or function of body parts.

Example: The homeotic genes play a crucial role in determining the body plan of an organism during its development.
