When the roots absorb the water it goThe xylem takes also part in food storage, support and the conduction of minerals. Xylem and phloem together form a continuous system of vascular tissue extending throughout the plant. The principal conductive cells of the xylem are tracheary elements, of which there are two types, tracheids and wood vessels. Both are elongated cells with secondary cell walls that lack protoplasts at maturity. They are completed by the xylem fibres and parenchyma cells. Much speaks on behalf of the origin of xylem fibres and wood vessels from the tracheids. \n\nSince 1851, the isolation and depiction of lignified cells is done according to the maceration procedure of SCHULZE. Small pieces of wood are covered with a mixture of potassium perchlorate and concentrated nitric acid. The complete volume should not be larger than 1/10 of the reaction container, because a lot of gas develops very quickly at cautious heating. The surfaces of the wooden pieces are strongly attacked. The single cells can be scraped off after washing of the preparation and examined under the microscope.

I'm not going to do your homework for you, but I will do my best to give you good links to help you answer the questions yourself.\n\nhttp://www.biology.arizona.edu/CELL_BIO/tutorials/meiosis/main.html\nhttp://www.accessexcellence.org/RC/VL/GG/meiosis.html\nhttp://www.emc.maricopa.edu/faculty/farabee/biobk/BioBookmeiosis.html\nhttp://www.sumanasinc.com/webcontent/anisamples/majorsbiology/meiosis.html\nhttp://biologyinmotion.com/cell_division/index.html\nhttp://www.csuchico.edu/~jbell/Biol207/animations/meiosis.html\nhttp://taggart.glg.msu.edu/bs110/meiosis.htm\nhttp://en.wikipedia.org/wiki/Mendelian_inheritance\nhttp://www.thebiotechdictionary.com/term/triploid\n\nI hope that helps. Most of the links explain meiosis. Some have animations to assist their explanations. The wikipedia article is about Mendel's law of independent assortment. The final link is to the definition of triploid. \nThat should make it easier for you to do the work on your own. By the way, congrats on attending college classes online. (I assume it is a college course.) It is a good idea to use as many resources as you can. When I don't understand subjects in my classes I usually look up the main terms in google.

Sat II Bio much? hehe\n\nI'd go for B. Bacterial metabolism can get very complex, while their genetical structure is very siple.

See if you can talk to any teachers that teach 9th grade biology.  Or any students that are in 9th grade bio.  They could probably give you a good idea of what you'll be covering.  Plus, if you show that much interest in doing well in biology, the teacher you talk to will definitely take notice.

This is not a pure biology question. Should be bio-chemistry.
