PLEASE I NEED HELP ASAP now I don't need the whole experiment to be done I just need some sort of paper with these in it because I can't find anything on this please I need help

EXPERIMENT: FUNGUS ALL AROUND (PART 2)
These supplies are needed:

compound microscope
sugar
5X or 10X hand lens
fresh whole mushroom
flashlight
depression slide
methylene blue stain
tweezers
medicine dropper
pin
cover slip
baker's yeast packet
cup or glass
sharp knife or razor blade
spoon
Yeast Observation:

1. In a glass, mix the contents of the baker’s yeast packet, a tablespoon of sugar, and two cups of warm (not hot) water.

2. Allow the mixture to sit for approximately ten minutes. You are waiting for the yeast cells to begin to grow and multiply.

3. Using the medicine dropper, place a drop of the yeast mixture into the well of a depression slide. Add one drop of methylene blue stain.

4. Place a cover slip over the sample. You may now carefully place your prepared slide on the microscope stage for viewing.

5. Focus the slide on low power. You may then switch the objective to high power and re-focus with tiny movements of the fine adjustment knob. Be sure to identify a reproducing yeast cell and the tiny bubbles of carbon dioxide given off by the cells. How does yeast reproduce? In the space provided in the document, sketch and label your yeast sample. Be sure to label all structures you are able to identify. Record the magnification of the high power objective.

Phylum Basidiomycota (Common Mushrooms)

Basidiomycota include common organisms such as mushrooms, toadstools, puffballs, bracket fungi, rusts, and smuts. We will discuss the most common representative of this phylum, the mushroom. You will not need a microscope to see a mushroom; however, some magnification is helpful for viewing some of the tiny structures of a mushroom.

The most conspicuous structure of a mushroom is the cap. The cap is the umbrella-shaped top of a mushroom and is the mushroom’s fruiting body. The underside of the cap contains structures called gills. The gills are the structures where reproductive spores are produced and released. Because of the shape of the spore-producing structures, mushrooms are grouped as club fungi. The mushroom cap and gills are supported by a stem-like structure called a stalk. Found on the stalk, another structure referred to as the ring can be identified. The ring is a structure left over from a protective covering that was present when the mushroom was first developing. The part of the mushroom that you can’t see without magnification is the hyphae (rhizoids) which grow into the organic material the mushroom depends on as its food source.

Most of us are familiar with mushrooms as a human food source. In fact, mushroom farming is a very big industry; in 2007, mushroom farmers in the United States produced 827 million pounds of mushrooms! Didn’t you ever wonder where all those mushrooms on your pizza came from? The most common kind of edible mushroom is Agaricus bisporis. These are the white mushrooms you can find in most grocery stores.

Of course, it would be best to note that not all mushrooms are edible. In fact, one type of mushroom is properly named a “death cap” mushroom. This mushroom produces a protein molecule which kills the human liver and kidneys. If this mushroom is mistakenly eaten, death will occur within five days if a liver and kidney transplant is not immediately available. Caution: Do not pick and eat wild mushrooms.

Mushroom Observation:

6. Obtain a fresh whole mushroom and a hand lens. Do you know what kind of mushroom you are looking at? If so, what is the scientific name? (example: Agaricus sports) In the space provided in the document, sketch and label your mushroom sample. Be sure to label all structures you are able to identify.
