AP BIOLOGY

Detailed explanation-1: -Some seeds have hooks or barbs that catch onto an animal’s fur, feathers or skin. Plants like pittosporum have sticky seeds that can be carried away by birds.

Detailed explanation-2: -Examples include mangoes, guavas, breadfruit, carob, and several fig species. In South Africa, a desert melon (Cucumis humifructus) participates in a symbiotic relationship with aardvarks-the animals eat the fruit for its water content and bury their own dung, which contains the seeds, near their burrows.

Detailed explanation-3: -Some seeds look a lot like Velcro. Some seeds have tiny hooks that help them stick to the fur of animals. Animals such as dogs or sheep can then move to a new place where the seeds fall off and grow. Some seeds look a lot like Velcro. Some seeds have tiny hooks that help them stick to the fur of animals.

Detailed explanation-4: -Seeds are carried from one place to another so that they get suitable conditions to grow, this is called seed dispersal. Seed dispersal is the mechanism by which plant seeds are transported to new sites for germination and the establishment of new individuals.

Detailed explanation-5: -Fur and Feathers Some seeds and fruits are adapted to stick to the fur or feathers (or clothing!) of unsuspecting animals; when the animal finally frees itself of its clingy passenger, the seed/fruit is usually far away from where it started.
