Mitosis/Cell Divison

why is cell division important for single celled organisms

• It the only way single cells can reproduce

• It kills single cells

• Cell division is not important for single cells

Why is cell division impoertant for multicellular organisms

• to grow and replace dead or damaged cells

• to reproduce

• cell division is not impoertant for multicellular organisms

Why is cell division important to an adult organism

• in normal cell turnover such as skin and gut

• To make them taller in height and in weight

• Cells have to divide to heal wounds like skin cut and broken bones

• Cell division is no longer important for an adult organism

Differentiation:

• A process that eliminates unecessary

• The difference between cells

• Cells that are identical but go into different parts of the body

Apoptosis

• Process that eliminates unecessary cells during development and removes unhealthy cells

• process in which cells regenerate to heal wounds or bones

• Programmed cell death
• Uncontrolled cell growth

What are cell cycle regulators?

• Hormones that regulate cell growth
• Lipids that maintain cell membrane integrity
• Carbohydrates that provide energy for cell division
• molecular signals that may stimulate or halt cell division, instruct cells to differentiate, or initiate cell death.

What happens if cell cycle regulators dont work properly

• Decreased cell division and potential cancer
• If regulators don’t function properly, an organism may end up with too few or too many cells

• Uncontrolled cell division and potential cancer
• Uncontrolled cell growth and potential cancer

Cell division occurs during

• mitosis

• digestion
• respiration
• photosynthesis

what happens during cell division

• The cell becomes larger
• Two daughter cells are formed
• The cell dies
• The cell splits into multiple cells

What is the cell cycle

• The cell cycle is the movement of cells within the body
• The cell cycle is the process of converting cells into energy
• The cell cycle is the elimination of old cells from the body
• The cell cycle is the series of events that take place in a cell leading to its division and duplication.
