Definition: A condition where there are two or more types of flowers that differ in the length of their reproductive parts, or the alternation between male and female generations in certain species.

Example: The plant exhibits heterogony, showing different flower types with varying stamen and pistil lengths.

Definition: Relating to a type of chemical reaction where a bond is broken and the electrons are unevenly distributed between the resulting fragments.

Example: In heterolytic cleavage, one atom takes both electrons from the bond, leading to the formation of charged species.

Definition: Having different forms or structures, especially at different stages of development or in different contexts.

Example: The species is heteromorphic, showing distinct physical forms during its life cycle.

Definition: A condition or characteristic where different forms or types exist within the same species or group.

Example: The study of heteromorphism helps scientists understand how species adapt to different environments.

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: A biological term that refers to the condition where two different mating types are required for sexual reproduction in certain organisms, such as fungi and algae.

Example: Heterothallism is important for genetic diversity in some species of fungi.
