Chloropasts are only found in plants because, they have colors that absorb sunlight and animals don't. Chloropasts use energy from the Sun to make food and animals don't.
Chloroplasts are not present in animals, from what I know.
Every one have mitochondia. Only some have chloropasts
Animals does not make food, so they do not chloroplasts in their body. So they will obtain their energy from food. (This is a rather short answer)
The endosymbiotic theory explains the origin of chloropasts and mitochondia. Symbiosis is the mutual benefit of two organisms living together. This was the basis of the theory.
The pigment chlorophyll which is actually struck by photons of light and energized enough to give an electron to photosystem II, thus a part of the photosynthetic process.
Chloroplasts are the organelles that contain chlorophyll in plant cells. Chlorophyll is a pigment that plays a key role in the process of photosynthesis, where it captures light energy and converts it into chemical energy.
They are organised into categories. Those categories are: Database functions Date and time functions Engineering functions Financial functions Information functions Logical functions Lookup and reference functions Math and trigonometry functions Statistical functions Text functions External functions Cube functions
There are infinitely many types of functions. For example: Discrete function, Continuous functions, Differentiable functions, Monotonic functions, Odd functions, Even functions, Invertible functions. Another way of classifying them gives: Logarithmic functions, Inverse functions, Algebraic functions, Trigonometric functions, Exponential functions, Hyperbolic functions.
You could not really classify formulas into types as the amount of formulas are infinite and you can have a variety of things happening in a formula. Functions come in categories, and that is maybe what you mean. It will depend on which version of Excel you have, but these are the categories available in later versions: Cube functions Database functions Date and time functions Engineering functions Financial functions Information functions Logical functions Lookup and reference functions Math and trigonometry functions Statistical functions Text functions
They are both statistical functions.
