Yes, I did. Mylink to celluar respiration. Don't lie.
An implanted fertilized egg does not, either. Nor does a fetus. Your point?
No that is the ability to have cells conduct respiration... that is not feeding off of an outside energy source..... because something WILL eventually do that does not mean that it IS doing that at the stage in question... see the seed in a vacuum scenario, again
OMG. Cellular respiration IS the uptake of nutrients and other compounds for energy.
Cellular respiration, also known as 'oxidative metabolism', is one of the key ways a cell gains useful energy. It is the set of the metabolic reactions and processes that take place in organisms' cells to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products. The reactions involved in respiration are catabolic reactions that involve the oxidation of one molecule and the reduction of another.
Nutrients commonly used by animal and plant cells in respiration include glucose, amino acids and fatty acids, and a common oxidizing agent (electron acceptor) is molecular oxygen (O2). Bacteria and archaea can also be lithotrophs and these organisms may respire using a broad range of inorganic molecules as electron donors and acceptors, such as sulfur, metal ions, methane or hydrogen. Organisms that use oxygen as a final electron acceptor in respiration are described as aerobic, while those that do not are referred to as anaerobic[1].
The energy released in respiration is used to synthesize ATP to store this energy. The energy stored in ATP can then be used to drive processes requiring energy, including biosynthesis, locomotion or transportation of molecules across cell membranes.

That's wiki, so maybe it is more clear.
