Water is needed for fertilization in several plant groups because the sperm needs to swim to meet the non-motile eggs of the female organs.
<em>However in angiosperms, the pollen germinates and a structure known as pollen tube which contains the male gametophyte (sperm) grows into the ovary where the ovule is located and the male gametophyte is deposited in the ovule to initiate the fertilization process.</em>
<em>Hence, water is really not necessary for fertilization in the angiosperms.</em>
It is called coevolution, when two species influence each other's speciation.

Answer:
CPT® Index - 96040
icd-10-cm code - Q99.2
Explanation:
Here in this case the diagnosis came out with fragility in X chromosome. This is some thing related with medical genetics. Hence, the CPT® Index for this scenario would be 96040. As per the American Medical Association, CPT® Index 96040 cover cases that fall into the category of “Medical Genetics and Genetic Counseling Services” which also involves counseling either with the patient or family for 30 minutes. The icd-10-cm code – Q99.2 deals with the problems associated with genetic abnormality
Hence, the answer is
CPT® Index - 96040
icd-10-cm code - Q99.2
