WARNING!! These next slides are very important!!

Mitochondria• FOUND IN BOTH PLANT

AND ANIMAL CELLS!!• Mitochondria are the cell's

energy producers. They convert energy into forms that are used by the cell. They are located in the cytoplasm and they are the sites of cellular respiration which generates fuel for the cell. Mitochondria are also involved in other cell processes such as cell division, growth, and even cell death. Found in plant and animal cells.

Important Vocab Words For Mitochondria

• Cristae are the internal compartments (finger like objects) formed by the inner membrane of a mitochondrion. The surface for chemical reactions to occur in the mitochondria. This allows the mitochondria to go through cellular respiration.

• In the mitochondrion, the matrix contains soluble enzymes that catalyze some steps of cellular respiration. The area between the cristae.

Chloroplast• FOUND ONLY IN PLANT

CELLS!!• Chloroplast are organelles

found in plant cells and other eukaryotic organisms that conduct photosynthesis. Chloroplasts capture light energy to conserve free energy in the form of ATP and through a complex set of processes called photosynthesis.

Important Vocab Words For Chloroplast

• Thylakoids are the flat, interconnected sacs.• Sometimes, thylakoids

are stacked, similar to poker chips. These are called granum. • Also, the fluid outside the

thylakoid is called the stroma. This contains enzymes, the chloroplast DNA, and ribosomes.

PEROXISOMES• Peroxisomes are organelles found

in virtually all eukaryotic cells. They are involved in the catabolism of very long chain fatty acids, D-amino acids, polyamines, and biosynthesis. The fatty acids they break down can be transported to the mitochondria so that the mitochondria can go through cellular respiration.

Common Characteristics of Mitochondria and Chloroplast

• Both make energy for the cell. They make it in different ways, but never the less, they both make the cells energy.

• Both have an outer and inner membrane. This adds protection for the organelle.
