Answer 1

The mode of dispersal of the seeds with their characteristic properties are as follows:
(a) Seeds with wings- Seeds of drumstick and maple are light in weight and can be blown away by air. Thus, these are dispersed by wind.
(b) Small and light seeds- Seeds of grasses and cotton have hairy structures and are dispersed through wind.
(c) Seeds with spines/hooks - Seeds of Xanthium have hooks or spines that can attach to the fur of animals and get dispersed. Therefore, these are dispersed through animals.
