What powers cellular activity?
You learned about how cells transport materials across the cell membrane.
How does the cell power such complex activity?
INVESTIGATION
Cell Strength
What do you notice about the two organelles to the left?
What are their differences, and what are their similarities
Can you infer what their functions are?
Mitochondria The bean-shaped organelle on top is called a mitochondrion,
and it powers the cell through chemical reactions. Mitochondria are found in
both plant and animal cells. It has two membranes to increase the surface
area for these reactions to occur. Mitochondria are a vital part of cellular
respiration. Cellular respiration is a series of chemical reactions that convert
the energy in food molecules into a usable form of energy called ATP.
Powering Plant Cells In addition to mitochondria, plant cells contain
organelles called chloroplasts (KLOR uh plasts). Chloroplasts are organelles
that use light energy and make food-a sugar called glucose--from water and
carbon dioxide.
