cell growth

Objectives

• Explain the problems that growth causes for cells.

Limits to Cell Growth

• The larger a cell becomes, the more demands the cell places on its DNA 

• If a cell were to grow without control, DNA overload would occur

Exchanging Materials

• Food, oxygen and water enter the cell through the cell membrane

• The rate at which this exchange takes place depends on surface area 

Multiple Choice

The amount of nutrients needed is determined by...

• The cell's volume
• The cell's surface area
• The cell's Rough ER
• The cell's Smooth ER

Multiple Choice

Which cells are more efficient at obtaining nutrients?

• Small Cells
• Medium Size Cells
• Large Cells
• X-Large Cells

Cell Division

• Before a cell becomes too large, it divides into two daughter cells 

• cell division.

What are Chromosomes

• Chromosomes are made up of DNA

• DNA carries the cell’s genetic code

• The cells of every organism have a specific number of chromosomes

• 46

• 21

• 10
