Cell Cycle and Diffusion

Why is diffusion and osmosis important to cells?

• It allows them to take in materials without using energy.

• It allows them to reproduce.

• It allows them to absorb sunlight.

• It allows cells to use all energy.

Why would it be important to replicate DNA before a cell divides in mitosis or meiosis?

• In order for genetic information to be transferred into daughter cells.

• In order for the cell to be able to increase in size.

• In order for the DNA to be contained in the nucleus.

• In order for the cell to re-order the DNA sequencing in the new cells.

The process by which the nuclear material is divided equally between two new cells

• mitosis

• cancer

• spindle

• centromere

The stages of mitosis in order

• Prophase, Metaphase, Anaphase, Telophase

• Anaphase, Prophase, Telophase, Metaphase

• metaphase

• prophase

• anaphase

• telophase

The last part of the cell cycle where the cytoplasm splits, and the cell finishes dividing into two cells is called _____________.

• prophase

• interphase

• cytokinesis

• duplication

The 1st stage of the cell cycle. A cell spends most of its time in this stage growing.

• Interphase

• Mitosis

• Cytokinesis

• Concentration

What is the primary purpose of the cell cycle?

• To allow cells to grow and divide

• To enable cells to move

• To help cells absorb nutrients

• To assist in cell communication

Which phase of the cell cycle is characterized by DNA replication?

• G1 phase

• S phase

• G2 phase

• M phase

What is diffusion?

• The movement of water across a membrane

• The movement of particles from high to low concentration

• The process of cell division

• The replication of DNA
