Mutations may be caused by environmental<span> factors such as radiation or chemicals. This is the structural and functional unit of all living organisms, and are sometimes called the "building blocks of life." This is </span>growing of cells in a synthetic environment<span>.</span>
Mutation are two types somatic and germ cell mutation...as there is mutation in germ cell it will alter the normal behavior and produce variation !
random fertilization also causes variation as different setup of genes meets with another different...so chances of variation increases !
and third crossing over is in meiosis when chiasmata forms....so in this two homologous chromosome attach to each other and on separation ... some part exchange so leads to variation !
The answer would be "plant-like protists". These protists make their energy on sunlight. This would make them a protist and a plant-like cell.
