Some oxygen atoms have extra electrons, making them ionized and giving them a negative electrical charge. DNA and RNA molecules are negatively charged because of these phosphate groups. ✓ a nitrogenous base: Nitrogenous bases are ringed molecules that contain the element nitrogen. Five different nitrogenous bases are found in nucleotides: adenine (A), cytosine (C), guanine (G), thymine (T), and uracil (U). DNA nucleotides contain A, C, G, and T, while RNA nucleotides contain A, C, G, and U. NH2 N 5' C C N C CH HC N O-O Figure 2-6: Structure of a nucleotide (adenosine monophosphate, an RNA nucleotide).

Often, they’re involved in breaking down lipids like fatty acids. In plants cells, glyoxisomes, a special kind of peroxisome, help convert stored oils into molecules that can be easily broken down for energy. ✓ Vacuoles are similar to vesicles in structure — they’re basically spheres of membrane, but they have different functions. The majority of space inside most plant cells — up to 95 percent of the cell volume! — is taken up by a large, central vacuole. The vacuole is separated by a membrane called the tonoplast.

Idea is that plants have chloroplasts instead of mitochondria. The right idea is that plants have both! Think about it — it wouldn’t do plants very much good to make food if they couldn’t also break it down! When plants make food, they store matter and energy for later. When they need the matter and energy, they use their mitochondria to break the food down. indd 39 6/3/11 7:08 PM 40 Part I: Plant Basics Like chloroplasts, mitochondria are surrounded by two membranes: the outer membrane and the inner membrane.
