Objectives February 1

Explain why cells are relatively small

Summarize the primary stages of the cell cycle.

Describe the stages of interphase.

Page 2: Objectives February 1 Explain why cells are relatively small Summarize the primary stages of the cell cycle. Describe the stages of interphase

Size MattersSize Matters!

Page 3: Objectives February 1 Explain why cells are relatively small Summarize the primary stages of the cell cycle. Describe the stages of interphase

What limits cell size

Ratio of surface area to volume. The bigger the ratio the better as a cell gets bigger the ratio shrinks.

Think Stadium gates!
