Lesson: Chapter 14 — Continuity of Life

14.2. Dispersal of fruits and seeds 2 of 5

Dispersal by animals

These fruits and seeds may have the following adaptations for carrying out dispersal by means of animals.

Having fleshy parts that can be eaten

Examples — mango, papaw.

Bearing attractive colours

Examples — cashew apple, banana.

Bearing hooks or hairs that help them stick

Examples — naga darana, Urena burrs, apple.

Bearing shapes and patterns that mislead animals

Examples — castor, olinda, madatiya, bitter gourd.

Figure to be added

Figure 14.15 — fruits and seeds dispersed by animals: mango, cashew apple and bitter gourd.

Eaten, carried, or mistaken for food

Three different bargains hide in that list. A fleshy fruit pays the animal, which eats it and drops the seed elsewhere. A hooked fruit hitches a ride on fur without paying anything. A brightly patterned hard seed is mistaken for food, carried off and abandoned.
