Why are seed plants an evolutionary advantage?
a. seeds allow the transport of water and nutrients
b. seeds develop into adults without sexual reproduction
c. seeds protect and nourishing young, growing plants
d. seeds provide the materials for photosynthesis

The correct answer would be c. seeds protect and nourishing young, growing plants.

Seed is the unit or characteristic of sexual reproduction of angiosperm and gymnosperm.

It is formed after fertilization and contains embryonic plant covered with a protective outer covering.

It serves two main functions or advantages over the seedless plants:

Nourishment and protection: It nourishes and protects the embryo. It contains a large number of food reserves (usually in the form of endosperm) in the form of starch, oils, and proteins. The food reserves give the boost the growth of seedling.

The seed coat protects the embryonic plant from mechanical injuries, drying out, and predators.

Dispersal: Seed reduces the dependency of plants on water for their propagation. They can be dispersed by various means such as wind, water, and animals.
