Answer to Question #188555 in Ecology for KAMVA

Question

Select a South Africa plant and produce an information sheet. This can be any plant, perhaps a garden plant or medicinal plant, and your information sheet should provide information on the plant and including the following:

 

•Name and classification of plant (from family to species)

•Photographs (images from internet will be fine, remember to add your source)

•Description (what does the plant look like?)

•Distribution (where does the plant occur in South Africa?)

•Ecology (anything interesting, e.g. pollinators)

•Red List status (this can be found at <span style="color: rgb(23, 41, 119);">http://redlist.sanbi.org/</span>)

•Uses

•References (a full list of references following Harvard Style. Remember to do in text referencing that corresponds with this list)

Answer 1

Cell division serves as a means of reproduction in unicellular organisms through binary fission. In multicellular organisms, cell division aids in the formation of gametes, which are cells that combine with others to form sexually produced offspring. ... The human body also repairs injuries by means of cell division.

B)what are the specialised ultrastructures that allow red blood cells to carry out its role? Answer===It contains haemaglobin which allows the binding of oxygen. Its biconcave shape maximises the surface area to increase efficiency of oxygen absorption. Its shape also allows it to ''squeeze'' through narrow vessels and can enter even the thinnest capillaries around the body

C)Breast cancers can be divided into two main overarching groups: the carcinomas and the sarcomas. Carcinomas are cancers that arise from the epithelial component of the breast. The epithelial component consists of the cells that line the lobules and terminal ducts; under normal conditions, these epithelial cells are responsible for making milk. Carcinomas comprise the vast majority of all breast cancers, and will be further discussed below. Sarcomas are rare cancers that arise from the stromal (connective tissue) components of the breast. These stromal component cells include myofibroblasts and blood vessel cells, and cancers arising from these "supportive" cells include phyllodes tumors and angiosarcoma. Sarcomas account for less than 1% of primary breast cancers.
