Question

1. list all 3 parts of the cell theory (slide 7 in cell theory ppt) 2. what is the difference between unicellular and multicellular? (slide 8) 3. what are the two different types of cells? (slide 9) 4. what are the 4 things that all cells have? (slide 12)

Explanation:

1. The three parts of the cell theory are: 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. Unicellular organisms are made up of a single cell and perform all life functions within that one cell. Multicellular organisms are composed of multiple cells, with different cells having specialized functions.
3. The two types of cells are prokaryotic cells and eukaryotic cells. Prokaryotic cells lack a nucleus and membrane - bound organelles, while eukaryotic cells have a nucleus and membrane - bound organelles.
4. All cells have a cell membrane (to regulate what enters and leaves the cell), cytoplasm (the jelly - like substance inside the cell), ribosomes (for protein synthesis), and genetic material (DNA or RNA).

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. Unicellular organisms consist of a single cell performing all life functions, while multicellular organisms have multiple cells with specialized functions.
3. Prokaryotic cells and eukaryotic cells.
4. Cell membrane, cytoplasm, ribosomes, genetic material.
