Think about it!
Have you ever heard of a cat, mouse, dog or human just budding off or reproducing without fertilization of an egg?
And, which is the only thing that doesn't fit that list? The violet - it's a plant, whereas the others are animals (and happen to all be mammals). That's a major clue.
Violets can reproduce asexually when the pollen is transferred to the ovule. All the others require two individuals, one male and one female, to produce a zygote.
Stomata: I dare you to look on Wiki. It's basically a cell in photosynthetic tissues of plants that open and allow gases to enter (like CO2, which it uses in photosynthesis). These stomata are opened and closed by guard cells. In desert plants (and those living in other hot environments), these cells are open at night in order to prevent dessication of the plant by evaporation.
Thus, the function of the stomata - you should be able to guess it.
Photosystems are made of a pigment that can absorb light energy and a series of molecules that send the excited electron on an energy-making cascade.
Fermentation is a type of cellular respiration that is undergone in the absence of oxygen. One end product, for example, is ethanol, produced by yeast (and many other organisms!).
Water absorption is done through roots.
The Calvin cycle (also called the Kreb's or citric acid cycle) is the cycle in which NADH and FADH2 are made to be used in the electron transport chain to make ATP, rather than making ATP by substrate level phosphorylation as in glycolysis. It occurs in aerobic respiration.

Stomata is a tiny opening or pore, found mostly on the underside of a plant leaf, and used for gas exchange.
Violet light is used to stimulate asexual reproduction. I dont see any animal on the list which can reproduce asexually.

lol haha. It's hilarious that you don't find the 1st answer obvious.
2nd answer is gas exchange. Air containing carbon dioxide enters the plant through these openings where it gets used in photosynthesis and respiration. Oxygen exits these openings.

A cat, mouse, dog and humand are all mammals and have 2 sexes. There are no instances where mammals reproduce asexually. This leaves you with one answer.
Stomata, these are pores in the leaf that allow carbon dioxide and water vapor to get into and out of the leaf. Which of the answers fits with this definition? (What are carbon dioxide and water vapor? hint they are gases)

water, gas exchange,.....water is actually lost from these pores through transpiration so i dont know why guy above me put that lol

first question: violet
second: i think it's gas exchange

Look in the BACK of your Science Book- under definitions. And hurry up about it because you have that TEST tomorrow! :)
