Animals can be categorized into 3 based on body symmetry
- <em>Those without any body symmetry (asymmetrical)</em>
- <em>Those with bilateral body symmetry (bilateria)</em>
- <em>Those with radial body symmetry (Radiata)</em>
Animals can be categorized into 2 based on number of embryonic germ layer;
- <em>Those with two layers - endoderm and ectoderm (diplobastic)</em>
- <em>Those with three layers - mesoderm in addition to ectoderm and endoderm (triploblastic)</em>
Animals can be categorized based on presence/absence of body cavity or coelom;
- <em>No body cavity - acoelomates</em>
- <em>False body cavity - pseudocoelomates</em>
- <em>True body cavity - coelomates</em>
Animals can be categorized into 2 based on characteristics of embryonic development;
- <em>Deuterostomes</em>
- <em>Protosomes</em>
Answer: The Calvin cycle has four main steps: carbon fixation, reduction phase, carbohydrate formation, and regeneration phase. Energy to fuel chemical reactions in this sugar-generating process is provided by ATP and NADPH, chemical compounds which contain the energy plants have captured from sunlight.
