endomembrane system does not include the membranes of either mitochondria or chloroplasts.
The word “coccus” has a couple of different meanings in biology<span>, but it most commonly refers to a type of bacteria that is spherical or slightly oval in shape. In this application, the plural term used to describe entire bacterial chains or infections is </span>cocci<span>, whereas a single coccus </span>bacterium<span> is called a </span>monococcus<span>. There are many different strains and species in this broad family. Some benefit life, either by helping keep cell balance or warding off other infections, while others can be quite harmful. In most cases the shape of the bacteria is useful for classification and evolutionary purposes but doesn’t say much about how it will perform or what it does. The bacteria’s individual coding and composition more commonly dictate these things.</span>

There are actually two red pigments found in certain vertebrates that function in oxygen transport (or storage). Hemoglobin is present in the blood of most vertebrates and binds oxygen molecules, in order to transport them to body tissues in need of oxygen for energy (ATP) production.
Myoglobin, mainly in mammals, is a protein (enzyme) found in red (skeletal) muscle cells, that aids in binding oxygen when it's plentiful being delivered via blood. The purpose is that in high stress, low oxygen situations such as strenuous exercise, the myoglobin releases its bound oxygen to provide it to the starving overworked muscle cells.
**Fun fact: it's the hemoglobin that gives the bright red color of blood when it's bound to oxygen, and the myoglobin of mammal flesh gives it the typical pinkish-red hue that is seen in mammalian meat (veal, steak, ham, venison, bison, etc.). Other non-mammalian animals (fish, birds, frogs, snake, alligator, etc.) tend to have lighter-colored skeletal muscle meat due to the lack of myoglobin, amongst other factors.
