Answer:

A pollen tube grows from the pollen grain into the ovary

Explanation:

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>

Why do scientists think it is necessary to develop new ways to create ethanol
Elena L [17]

Answer:

Due to the cost and resource input (specially the land) required for producing ethanol

Explanation:

In current time most of the ethanol is produced by fermenting corn, sugarcane or other plants at high temperature. In this process of fermentation, liquid bio fuel is produced.  

These plants and crops require large area for cultivation and production along with huge inputs of fertilizers and water. As per an estimate , 3 gallons of ethanol require bushel of corn that intakes 800 gallons of water which is a huge cost to any nation or individual
