Arborjet > Diseases > Anthracnose. Anthracnose (leaf blight) is a fungus that winters on twig tissue on the tree. In the spring, spores are transported to new buds and shoots. The disease is enhanced by cool, wet conditions. Infected leaves develop tan to reddish brown lesions that extend along the veins of the leaf.
These tables give the total number of chromosomes (including sex chromosomes) in a cell nucleus. For example, human cells are diploid and have 22 different types of autosome, each present as two copies, and two sex chromosomes. This gives 46 chromosomes in total.
â¢ Haploid cells are produced by meiosis, and diploid cells are produced by mitosis. â¢ Diploid cells have the same number of chromosomes as the parent cell, and haploid cells have only a half of the number of chromosomes as the parent cell.ince each gamete has only one set of chromosomes, the end resulting zygote will have only two sets of chromosomes. That is the zygote becomes diploid. If the gametes were not haploid cells, the result at the end would be a zygote with four sets of chromosomes.
