Plot Hay Infusion
From our plot, we gathered grass, twigs, soil, and leaves and put them in a cup to create a hay infusion. To create our hay infusion, we took nutrient filled water and poured it into our cups which was filled with out gathered materials. After a day or so of waiting, the infusion was done and was ready to be looked at under the microscope.

Here we see, at the end of the pointer, a rare find recognized as a Phylum; Ciliates, Vorticella.
- Vorticella, are a group of single-celled organisms called ciliates. One of the unusual features of ciliates is that they have two nuclei. The larger one, called a macronucleus contains many copies of the cell's genes. The smaller nucleus is called a micronucleus.
- Vorticellas reproduce by a process called binary fission. During binary fission, the cell divides into two daughter cells. The macronucleus gets long, then divides in two as the rest of the cell is dividing, so each of the daughter cells ends up with roughly half of the original genetic material (2000, Allison J. Gong).

Here we see an organism part of the Phylum; Ciliate.
- Ciliates reproduce by two methods.
- In binary fission, one cell divides into two equal halves, producing two identical daughter cells.
- In conjugation, two individuals come together and exchange nuclear and, in rare cases, cytoplasmic material. They then separate and each one then undergoes many divisions before conjugation occurs again. Each of the new cells formed contains hereditary material from both the original parent cells (2013, Nature&Animals).

To the left we see an organism part of the Phylum; Chlorophtya. Chlorophyta is usually a division of green algae.
- Asexual reproduction, in which offspring arise from a single organism, and inherit the genes of that parent only.
- Meiosis, where the parent plant releases gametes. They join together and grow into new parent cells. A zygote is formed by two gametes joining together.
- Another types of sexual reproduction some algae utilize, forms swimming cells called zoospores that move about on the water. These grow into two types of short threads or filaments which produce the gametes.One thread produces eggs and the other produces sperms. These join together to the bottom of the ocean and become a small leaf-shaped plant. In time, it grows into a large plant (2000, Kate Bruffey).
