The process of mitosis starts with one parent cell, and results in two identical daughter cells. During ______, the cell elongates and pinches inward, while the nuclear envelope re-forms. In ____, the chromatids begin to pull apart and move to opposite poles. During ____ the nuclear envelope begins to break down, and the chromosomes fully condense. In ____ , the centrioles migrate to opposite ends of the cell, while the chromosomes line up in the center, ready to divide.

• telophase, anaphase, prophase, metaphase

• metaphase, anaphase, prophase, telophase

• prophase, metaphase, anaphase, telophase

• prophase, anaphase, telophase, metaphase

Cell 2 is larger than 10 micrometers, has membrane bound organelles and a nucleus.

• cell 1 is eukaryotic, cell 2 is prokaryotic

• cell 1 is prokaryotic, cell 2 is eukaryotic

• Both cell 1 and 2 are eukaryotic

• Both cell 1 and 2 are prokaryotic

What type of cell is shown here?

• bacteria

• plant

• animal

• fungus

Is this organism a prokaryote or a eukaryote?

• Eukaryote because it has organelles similar to plants, animals, fungi and protists

• Eukaryote because the organism is unicellular and has nucleus.

• Prokaryote because it is a primitive life form and does not have a nucleus

• Prokaryote because it has a plasma membrane, cell wall and a nucleus
