lab: examine root nodules from clover plants under the dissecting microscope and also examine prepared slides of rhizobium under the light microscope. Clover plants can be sampled from the garden and your teacher will look in the slide collection in the back room to see if the rhizobium slides are there. if not, you will observe these when I return next week. --S.N.
We know that plants are important to the ecosystem because they photosynthesize. Did you know that some plants are legumes and these are special because they have ROOT NODULES which are nitrogen fixers. These root nodules are little rooms where Rhizobium bacteria convert nitrogen gas into ammonium and then Nitrobacter bacterium in the soil converts ammonium into nitrates. Plants can absorb nitrates to make plant protein. When those plants are eaten by animals, then animals use the nitrogen to make animal protein. You can say that all the protein on your body (muscles, enzymes, hair, fingernail etc) was built from nitrogen which was fixed by Rhizobium at some point in time.
ASSIGNMENT: 15 POINTS
15 points total. Draw a picture of root nodules under the dissecting microscope and also a picture of root nodules under the light microscope. Hand this in on TEAMS.
10 points
Only certain plants contain these root nodules...amongst them are bean plants and clover plants. Look at the roots of clover and draw a picture of root nodules.
This picture is from research done by Tashiro et al on the genetics of clover plants. https://www.researchgate.net/publication/250119450_Leaf_Trait_Coloration_in_White_Clover_and_Molecular_Mapping_of_the_Red_Midrib_and_Leaflet_Number_Traits
MICROSCOPE WORK:
EXAMINE PREPARED SLIDES OF ROOT NODULES UNDER THE MICROSCOPE and MAKE A CAREFUL DRAWING. IF THE PREPARED SLIDES ARE NOT AVAILABLE THEN DRAW FROM THIS WEBSITE:
YOUR TEACHER WILL REVIEW THE MAIN CONCEPTS OF MICROBIOLOGY. YOU WILL USE CLASS TIME TO DO THE ASSIGNMENT AND THE ASSIGNMENT CAN BE GROUP WORK.
This is an Introduction to Microbiology Notes, which cover Virus, and Monerans, with a mention of unicellular fungi. Read this document as an overview.
A virus that uses the lysogenic life cycle is termed either a provirus or prophage. What causes various proviruses to shift to the lytic cycle is not completely understood, but in some cases stress is the stimulus.
COVID-19 is a virus that undergoes a lytic cycle, but it does not explode cells, instead, it simply gets released from a cell
