<span>For the purposes of this discussion, it is important to note that elements are the basic components of Chemistry. Elements contain atoms. All substances are made up of elements. Compounds are elements that contain more than one type of atom that bond together via a chemical reaction. Mixtures are made up of more than one substance, element or compound that are not chemically bonded together. Compounds and mixtures impact our daily lives because everything we have is made up of elements. An example of a mixture is strawberry ice cream. Milk, cream, and other elements are mixed together to make the ice cream. An example of a compound is water. A droplet of water is made from two hydrogen molecules (elements) and one oxygen molecule. </span>
Alternation of generations in plants permits both mitosis and meiosis but at different stages.
The zygote will undergo many rounds of <u>mitosis</u> and give rise to a diploid multicellular plant called a sporophyte. Specialized cells of the sporophyte will undergo <u>meiosis</u> and produce haploid spores.
When it is said that mutation is the ultimate source of genetic variation it means that it creates several new combinations which is similar to meiosis and fertilization because <span> new alleles and genes appear. It is just about some common points.</span>
