Definition: Relating to a specific group of insects known as true bugs, which have forewings and hind wings that are different from each other.

Example: The heteropterous insects can often be found in gardens, where they play a role in pest control.

Definition: The increased strength, growth, or health that occurs when two different varieties or species are bred together.

Example: Farmers often use heterosis to produce stronger and more productive crops.

Definition: Describing organisms that produce two different kinds of spores that vary in size and reproductive function.

Example: Many plants are heterosporous, meaning they produce both large and small spores for reproduction.

Definition: The state of producing two different types of spores, typically microspores and megaspores, which is common in certain plants.

Example: Heterospory is an important adaptation in the evolution of seed plants.

Definition: Referring to organisms that produce male and female reproductive structures in separate individuals or forms, commonly seen in certain types of algae and fungi.

Example: Some species of fungi are heterothallic, meaning they require two different mating types to reproduce.

Definition: Relating to a hybrid form or theory that combines elements from different sources, often used in the context of genetics or string theory.

Example: The heterotic model in string theory merges features from two different theoretical frameworks.

Definition: Describing something that occurs in an abnormal location or in different habitats.

Example: The researchers studied heterotopic bone formation in patients after surgery.

Definition: Describing organisms that cannot produce their own food and must obtain nutrients by consuming other organic matter.

Example: Humans are heterotrophic because they need to eat plants and animals to survive.

Definition: A condition in which an organism cannot produce its own food and relies on consuming other organisms for energy and nutrients.

Example: Humans are an example of heterotrophy because we eat plants and animals for sustenance.

Definition: Relating to or characterized by different types or forms, often used in biological contexts to describe variations in structure or function.

Example: The study focused on heterotypic cells that exhibit different characteristics compared to their homotypic counterparts.
