Detailed explanation-1: -D. Deep Roots. The plant adaptations allow plants to use animals to transport their seeds to new locations is sweet fruit. The correct option is C.

Detailed explanation-2: -Animal dispersal Animals disperse seeds in several ways. First, some plants, like the burr at left, have barbs or other structures that get tangled in animal fur or feathers, and are then carried to new sites. Other plants produce their seeds inside fleshy fruits that then get eaten be an animal.

Detailed explanation-3: -Plants that depend on animals for dispersal have seeds that are adapted to traveling on the outside or the inside of the animal. Seeds with burrs or hooks can attach to an animal’s fur. For seeds that are transported internally, plants provide an attractive fruit pulp reward in return for the ride.

Detailed explanation-4: -Some have a parachute-like structure to keep them afloat. Some fruits-for example, the dandelion-have hairy, weightless structures that are suited to dispersal by wind. Seeds dispersed by water are contained in light and buoyant fruit, giving them the ability to float.

Detailed explanation-5: -Fruits are ripened ovaries which promote the dispersal of seeds. Fruits have adaptations that harness energy from wind, water, drying, or animals to disperse seeds. Animals transport seeds by eating fruits, storing seeds, or picking up burrs on fur or clothing.
