I need to break away from the pencil tool. |

I like it! Especially the little dude sitting against the tree. |

Hormones called auxins cause gravitropism in roots through their interaction with dense statoliths which sink to the bottom of the cell and effect the polarity of active auxin carrier proteins (possibly due to cytoskeleton disruptions). This change causes auxin to be transported downwards. As the cells at the top have a lower concentration of auxin, they elongate more, causing the roots to bend towards the force of gravity. Auxin has the opposite effect in stems, causing upward growth. Nice drawing. Sorry for the science guy moment, but I instantly thought of that when I saw this picture. For some reason, to be a doctor I have to understand how plant hormones work. |

at first I thought this was a spleen or a pancreas or a kidney.. the colors are very biology textbook! then I noticed the little guy leaning against the trunk. : ) the shading is delicate and nuanced for the pencil tool, I think (if that's what it is, I don't know shi tools well). good stuff |

Wow Gendaru, I never knew that. I honestly had no intention of my picture making sense. But hey :] |

I didn't realize that plants had hormones. The only things I remember from taking botany about ten years ago were something about monocots and dicots, and that taking a sample of a succulent plant and sealing it to a notecard is an exercise in futility. |

Plants even have some hormones that may have partially developed before they diverged from animals. Some insects freeload those messengers to decide when to molt. When the plants are having a good year, the insects consume more growth-associated hormones and molt (thus growing) more often. Oh, and Viagra makes cut flowers last longer, because it interferes with the same enzyme that exists in plants. In humans the enzyme suppresses the erection response, in plants it causes wilting. The more of this shit you learn, the more laughably impossible it is to ignore evolution. I also thought brain when I saw this picture too. |
