There are many different species of Algae which can range in size from microscopic to a couple meters long. Phytoplankton is at the bottom of the food chain and is eaten by small crustaceans which are called Zooplanktons. Zooplanktons are eaten by fish, invertebrates, mollusks, ducks, and turtles. • Plants: Around fifty species of food and shelter providing plants- Plants along with Algae provide the Rideau River with oxygen. Some of the plants in the Rideau River are carnivorous.
Andrew Hodgkiss Unit 22 Information sourced from various sites on the Internet. Bacteria, viruses, fungi, and parasites: The first bacteria a usual size is but a few micrometers in length shapes ranging from spheres to rods and spirals. Bacteria are present in most of the Earths habitats such as soil, water, acidic hot springs and radioactive waste also, found in/on animals and plants. Some bacteria are beneficial to human existence others can be fatal in developed countries antibiotics are used to treat bacterial infections. Viruses are small infectious agents that replicate only inside the living cells of other organisms, Viruses infect all types of life forms from animals, plants and bacteria.
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.
They are ten to 100 times larger than viruses. A virus is a small infectious agent that can replicate only inside the living cells of organisms. Most viruses are too small to be seen directly with a light microscope. They infect all types of organisms, from animals and plants to bacteria and Achaea. All viruses have genes made from either DNA or RNA, long molecules that carry genetic information; all have a protein coat that protects these genes; and some have an envelope of fat that surrounds them when they are outside a cell.
Name and describe the function of the five plant hormone groups discussed in your text. 5. Describe sexual and asexual reproduction in flowering plants. Be specific in regards to flowering plants. 1) Monocots are shorts for “Monocotyledons” which means plants whose embryo has one cotyledon; whereas, Eudicots (Eudicotyledons) carry embryo with 2 cotyledons.
Some fungi have beneficial uses. For example, penicillin and yeast for baking. Thrush is a common fungal infection. Parasites are small organisms which depend can only live on a host. Plants, animals, humans, fish, birds and reptiles can all be host to parasites.
Other features Shubin said evolved are the abilities of sight, smelling, and hearing. Just like today, we use different opsins to see in color than we do in black in white. Colored vision was not something found in any animal, until the gene in a mammal from millions of years ago duplicated and the copies specialized for different light sources instead of just black and white. Neil’s believes colored vision is in relation with the plants of the earth, and how it may have enabled creatures such as monkey’s tell the difference between types of fruits and leaves. All in all, Your Inner Fish was not my favorite book due to its dryness,
Causes and Spread of Infection The differences between Bacteria, viruses, fungi and parasites are Bacteria are found everywhere ie, air, water, soil, animals, people and food. It is a single cell micro-organism that retrieves its nutrition from the environment. Bacteria can only be seen through a microscope. They are shaped like short rods, spheres or spirals. It is stated on www.biologyinfo.com that, “Not all bacteria are harmful.
If we were to only have local products available to us today, we would have plenty of dairy, but shortages of most everything else. In fact, Vermont produces less than it consumes in every food category other than dairy. Vermonters eat far greater amounts of meat, poultry, eggs, grains, beans, fruits and vegetables than is produced locally. When the lack of diversity is compared to our diets, food grown locally in Vermont has the potential to feed only 38% of the population. That is to say, that if all food produced in Vermont were to stay in Vermont, there may be enough food to feed all Vermonters in terms of calories, but the lack of diversity makes it impossible to survive on these foods.
Najey Mcduffie March 12, 2012 Biology/ Pd. 4 Mr. McMillian Methods In Which Tapeworms Survive The immune system is made from cells, proteins, tissues, and organs, it is supposed to protect people from germs and microorganisms (2). It usually does a great job at protecting people, but somehow the immune system is unable to detect the tapeworm. Although tapeworms have no digestive system of their own, they acquire nutrients from partially digested food, through their skin as it goes through the person they inhabit. Tapeworms can grow to be at least twenty-two feet in somebody’s body.
