Answer:
<h2>
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.
Regulation
It is vital that the level of ATP in cells remains constant, especially when the demand for energy increases. ... Although high levels of reactive oxygen species lead to cell death and disease, low levels of these species are important for regulating normal cell processes.
I am a 2 year biology teacher so this is the answer. Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.:D
