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.
A haploid cell has only one set of chromosomes while diploid cell has two sets of chromosomes. 2. The somatic cells are diploid and the gametes are haploid in humans. 3. Diploid cells are developed as a result of mitotic cell division whereas haploid cells are developed as a result of meiotic cell division. 4.
