A) Protection of the zygote from the drying effects of air was important.</h2>
Explanation:
Diploid germ cells divide by meiosis to create haploid gametes, like sperm or egg.
Haploid gametes contain half genetic material as compared to the parent cell. Male and female gametophytes release sperm and eggs respectively. When an egg is fertilized by sperm, it becomes a diploid zygote.
Zygote matures into a sporophyte on the gametophyte plant. There is very important of protection of zygote from damage, so Protection of the zygote from the drying effects of air was important.
The food we consume is then processed and essentially extirpated into two forms, waste and nutrients. The nutrient rich category is used, or stored for when needed. Similarly, sugar is either used for energy once consumed, or stored in fat cells for when needed.

GAS EXCHANGE: the intake of Oxygen and the expulsion of Carbon dioxide. In the capillaries of the alveoli, oxygen travels due to the concentration gradient into those capillaries. Carbon dioxide is then expelled from those capillaries.
RESPIRATORY MEDIUM: is air for animals and water for fish. It is basically the substance through with living animals receive their oxygen.
RESPIRATORY SURFACE: is where the gaseous exchange takes place. The oxygen and carbon dioxide move across the respiratory surface entirely by diffusion.
