Question

section vocabulary cell the smallest functional and structural unit in all living organisms, usually consists of a nucleus, cytoplasm, and a membrane cell membrane a phospholipid layer that covers a cells surface and acts as a barrier between the inside of a cell and the cells environment eukaryote an organism made up of cells that have a nucleus enclosed by a membrane; eukaryotes include protists, animals, plants, and fungi but not archaea or bacteria nucleus in a eukaryotic cell, a membrane - bound organelle that contains the cells dna and that has a role in processes such as growth, metabolism, and reproduction organelle one of the small bodies in a cells cytoplasm that are specialized to perform a specific function prokaryote a single - celled organism that does not have a nucleus or membrane - bound organelles; examples are archaea and bacteria wordwise the prefix pro - means \before\. the root karyon means
ut\ or \kernel\. 1. identify what are the three parts of the cell theory? 2. compare complete the chart below to compare prokaryotes and eukaryotes. prokaryotes eukaryotes no cell wall no nucleus membrane - bound organelles one cell genetic material is dna 3. apply concepts you have just discovered a new organism. it is a single cell and has a cell wall but no nucleus. what kind of organism is it? explain your answer

Explanation:

1. The cell theory has three parts: All living organisms are made up of one or more cells; the cell is the basic unit of life; all cells come from pre - existing cells.
2. Prokaryotes: may have a cell wall, no membrane - bound organelles, single - celled, genetic material is DNA. Eukaryotes: can be single - celled or multicellular, have a nucleus.
3. Since the new organism is single - celled, has a cell wall and no nucleus, it is a prokaryote as prokaryotes are single - celled organisms without a nucleus and some have cell walls.

Answer:

1. All living organisms are made up of one or more cells; the cell is the basic unit of life; all cells come from pre - existing cells.
2. Prokaryotes: cell wall (in some), no membrane - bound organelles, single - celled, genetic material is DNA. Eukaryotes: can be single - celled or multicellular, has a nucleus.
3. It is a prokaryote. Because prokaryotes are single - celled, lack a nucleus, and some have cell walls.
