Hey there! I'm Sprout, And today i will be telling you all about how i am alive and how i function.
First off, There is a reason i stand so tall. Turgor Pressure from water! This process allows the vacuoles in my cells to expand making me strong and proud. When it rains i absorb the water and such process occurs. Water pushes the cell wall. if not, i proceed to wilt.My xylem assists in this process as it allows water to travel.
Sometimes, I use other ways to adapt to whats around me. These adaptations are called Tropisms. These allow me to do a number of things. It is my response to certain stimuli. Sometimes i can lean toward the sun (phototropism, Protrude upward or downward (gravitropism), or even towards water , or away fro it with my stem (hydro tropism).Furthermore, i can even respond to touch , wrapping around vines and opening and closing my leaves(thigmotropism).
Secondly, I obviously don't have a mouth (don't ask how i'm talking) so i tend to make my own food! I use CO2 and the sun to supply nutrients (also water) and i can make my own glucose. all of this gives me my beautiful colour and it takes place here! This change comes from Radiant to Chemical energy.
My sprouting is also an interesting process. My sprouting keeps going upward and my roots grow deeper. The forces from all things allow me upward and i start relying on turgor pressure for my expansion upward. When i am just a seed, i reside in the ground , to grow upward i use stored chemical energy , kept in my casing. Furthermore this allows my casing to fall off from pressure and protrude me upward.
