Question

read the information at station card and complete the activities below

1. define cytokinesis in your own word
2. complete venn diagram to compare cytokinesis in plant and animal cells.

station ii: cell cycle and cancer

1. what does this video define cancer as?
2. what happens when cells break off a malignant tumor?
3. what is the name of a mass of cells that

Explanation:

1. For question 41: Cytokinesis is the final stage of cell division where the cytoplasm of a parent cell splits into two daughter cells, completing the formation of two separate cells.
2. For question 42 (Venn Diagram):

• Cytokinesis in Plant Cells (unique): Forms a cell plate that develops into a new cell wall to split the cell.
• Overlap (shared): The end goal is splitting one parent cell into two genetically identical daughter cells, finalizing cell division.
• Cytokinesis in Animal Cells (unique): Forms a cleavage furrow to pinch the cell into two.

1. For question 43: Cancer is defined as a disease characterized by uncontrolled, abnormal cell growth and division that can invade surrounding tissues.
2. For question 44: A mass of cells that results from uncontrolled cell growth is called a tumor (benign if non-invasive, malignant if invasive).
3. For question 46: When cells break off a malignant tumor, they can travel through the bloodstream or lymphatic system to other parts of the body, forming new tumors (this process is called metastasis).

Answer:

1. Cytokinesis is the process where a parent cell's cytoplasm splits to form two full daughter cells, finishing cell division.

42.

• Cytokinesis in Plant Cells: Forms a cell plate → new cell wall
• Overlap: Splits parent cell into two identical daughter cells
• Cytokinesis in Animal Cells: Creates a cleavage furrow

1. Cancer is uncontrolled, abnormal cell growth that can spread to other tissues.
2. Tumor
3. The detached cells can spread via blood/lymph to other body parts and form new tumors (metastasis).
