When a metatarsal bone, a bone connecting the toe to the rest of the foot, is involved, pain will be felt in the upper foot. Metatarsal Bone Spurs-A bone spur in one of the metatarsals often coincides with a presence of arthritis in the area, and both the spur and the arthritis may require treatment.
Haploid organisms such as fungi, yeast, and algae can have complex cell cycles, in which the choice between sexual or asexual reproduction is fluid, and often influenced by the environment. Some organisms, in addition to their usual haploid state, can also exist as diploid for a short time, allowing genetic recombination to occur.
Haploid cells are produced by meiosis. During meiosis, the chromosome number is halved from the diploid number to the haploid number. Similar to mitosis, in meiosis also, DNA replication takes place in the parent cell during the interphase.After this, two cycles of nuclear divisions and cell divisions take place. Diploid cells are genetically identical to the parent cell, and haploid cells are not genetically identical to the parent cell. â¢ Haploid cells are important in sexual reproduction, and diploid cells are important in growth, asexual reproduction and genetic stability.
