Final answer:
The main purpose of seeds is to protect and distribute the zygote in plants
Step-by-step explanation:
The main purpose of seeds in plants that have them is to protect and distribute the zygote (fertilized egg). Seeds contain the developing embryo of the plant, protected by a seed coat, which helps to prevent damage and dehydration. Seeds also have mechanisms for dispersal, allowing them to be spread away from the parent plant, increasing their chances of finding suitable conditions to grow.
For example, some seeds are dispersed by the wind, such as dandelion seeds, which have feathery structures that enable them to be carried by air currents to new locations. Other seeds may be dispersed by animals, either by sticking to their fur or feathers, or by being eaten and later excreted, allowing the seeds to be deposited in a new location.
In summary, seeds serve as a means of protecting and dispersing the zygote, ensuring the survival and reproduction of the plant species.
