Cell Wordle
I choose these words because some of these words describe the cell. It is known as a building block and is the smallest unit of life. I included Robert Hooke because he was one of the first to describe it after looking through a microscope observing cork. I also included some of the organelles in a cell.
Bacteria, Virus, Prion, Protists,
Bacteria: A bacteria's complex structure is made up of a cell wall, thin cell membrane surrounding hte ctoplasm. It contains chromosomes that contains DNA needed to make copies of itself.
Virus: A virus' size is much smaller than a bacteria. Its structure is much simple. These infectious particles are made up of a protein coat and a core of either RNA or DNA and sometimes a membranous envelope. They can only reproduce inside the cells of a host.
Prion: A prion is an infectious protein that needs a host to survive. It can cause tissue damage and cell damage. It can exist in multiple forms compared to viruses.
Protist: Protists are a group of eukaryotic microorganisms. They live in any environment that contains water. Many are photosynethic and are primary producers in the ecosystem. Some protists reproduce sexually while others reproduce asexually.
Virus: A virus' size is much smaller than a bacteria. Its structure is much simple. These infectious particles are made up of a protein coat and a core of either RNA or DNA and sometimes a membranous envelope. They can only reproduce inside the cells of a host.
Prion: A prion is an infectious protein that needs a host to survive. It can cause tissue damage and cell damage. It can exist in multiple forms compared to viruses.

Beneficial Bacteria
Lactobacilli: this is a bacteria that helps converts lactose and sugars into lactic acids needed for the prevention of harmful bacteria. In humans it can be found in the digestive tract and in the vagina. It produces vitamin K and hydrogen peroxide that causes infections. It can also be found in yogurt.
Bifidobacteria: This bacteria helps the immune system and good digestion. It produces lactic acid that causes yeast infections in women. As people get older the number of bifidobacteria in their body decreases.
Streptococcus: This is used to treat diarrhea and helps the digestive system. It reduces the symptoms of baby colic and AIDS.

Plant Divisions
Bryphytes: branch of plant science that involves mosses, liverworts, and hornworts. It is most common in wet areas where they provide a habitat for tiny animals. They do not contain vascular tissue and therefore are "nonvascular" plants
Pteridophytes: seedless vascular plants that include lycophytes, ferns, whisk ferns,and horsetails. they have roots that is similar to the early vascular plants. Early vascular plants formed during the Carboniferius period.
Coniferophyla: It is the largest of the four gymnosperm phylum. It includes pines, firs, spruces, larches, yews and junipers. There are about 550 species left and only a few dominate the Northern Hemisphere. They are mostly evergreen. These plants are able to survive stressful environments
Angiosperms: These are flowering, vascular seed plants that produce fruits and flowers. It is very diverse and it widely distributive around the world. There is currently 250,000 known species. There are two classes that make up the angiosperm: monocots and dicots. Monocots have leaves with veins running parallel while dicots ahve netlike venation on their leaves.
