Parasites: A parasite is an organism that lives in another organism. It is dependent on its host for survival. It has to be in the host to live, grow and multiply. A parasite cannot live independently. There are several types of parasites such as Ectoparasite- which is a parasite that lives on the host’s surface, examples will be hair and body lice and mites.
Although they are eukaryotes like plants and animals, the major difference is that fungal cells have cell walls that contain chitin, unlike the cell walls of plants, which contain cellulose. Fungi lack the chlorophyll necessary for photosynthesis and must therefore live as parasites or saprophytes Parasites: plant or animal that at some stage of its existence obtains its nourishment from another living organism called the host. Parasites may or may not harm the host, but they never benefit it. They include members of many plant and animal groups, and nearly all living things are at some time hosts to parasitic forms. Many bacteria are parasitic on external and internal body surfaces; some of these invade the inner tissues and cause disease.
This happened because the plate was given no bacteria or anything to start growth. 4. The only plate where the E. coli should glow is on the LB/A/X+ plate. The reason for this is that it was the only plate that was given pBlu and no anti-biotic. This causes it to reproduce blue colonies of bacteria.
When a virus enters the body, it enters some certain cells and takes over making the now host cell make the parts the virus needs to reproduce, the cells are eventually destroyed through this process. The most common viruses is the common cold, which has no cure. Fungi Mould, yeast and mushrooms are all types of Fungi. Fungi live in the air, water, soil and on plants and they can live in the body, usually without causing illness. Some fungi have beneficial uses.

Unit 4222 – 265 Causes and spread of infection 1) 1.1) Bacteria, fungi and parasites are considered living where as viruses are not. Bacteria is a single celled organism and unlike viruses do not need a living host to reproduce. Fungi are multi-cellular organisms and parasites are any vectors that require a living host in order to reproduce. 1.2) Bacteria: - MRSA - Coccidiosis - Food poisoning - Pneumonia Viruses: - Influenza - Common cold - Ear infections - HIV/Aids Fungi: - Valley fever - Athletes foot - Ring worm - Yeast infection Parasites: - Worms - Maleria - Leishmaniasis 1.3) Infection is the invasion of body tissues by disease causing micronisms. Colonisation occurs whenever any one or more species populate an area.

Each stamen generally has a stalk called the filament (from Latin filum, meaning "thread"), and, on top of the filament, an anther (from Ancient Greek anthera, feminine of antheros "flowery," from anthos "flower"), and pollen sacs, called microsporangia. The development of the microsporangia and the contained haploid gametophytes, (called pollen grains) is closely comparable with that of the microsporangia in gymnosperms or heterosporous ferns. The pollen is set free by the opening (dehiscence) of the anther, generally by means of longitudinal slits, but sometimes by pores, as in the heath family (Ericaceae), or by valves, as in the barberry family (Berberidaceae). It is then dropped, or carried by some external agent — wind, water or some member of the animal kingdom — onto the receptive surface of the carpel of the same or another flower, which is thus pollinated. It is the part that contains the sperm
The same plant species may hold significant meaning in one area and be ignored elsewhere. The Quinine tree (Alstonia Constricta), commonly known as Bitter Bark, Fever Bark and Australian Febrifuge is native to North Western NSW and South East QLD. It’s also known as Lacambie or Lecambil by the Aborigines of the Clarence River (Lassak & McCarthy 2011, p. 101). The bark of the tree has a variety of medicinal uses. The two types of traditional resources used in regards to the medicinal uses of the Quinine Tree were written book literature and video interviews/documentaries with the knowledge holders of this region.
I would think some of the health risk involved with this plant will be the same in its native land. As far as growth in those regions, its natures intent for these species to live within its natural ecosystem. As of now, no biological control agent for African rue is available in the United States. Since biological control agents take years to research, develop and release, no releases are expected in the foreseeable future. (Wargo) Herbicides can be used in locations that are
