Phototropism is a plant's response to light, causing it to grow towards the light source. This happens because light triggers the production of a hormone called auxin, which moves to the shaded side of the plant and stimulates cell elongation, causing the plant to bend towards the light.
Grow
A stem or stalk typically holds up the flower in most plants. This part of the plant provides support for the flower to remain upright and accessible for pollination. Some plants may also have specialized structures such as bracts or peduncles to hold up the flower.
A meat used to hold a plant upright is a "steak." This term can refer to either a cut of meat or a wooden or metal rod used for support in gardening.

To act as a conduit for sap and to hold the flowers upright.
Vacuoles maintain the cell turgidity to keep the plants upright.

Phototropic is a word to describe if the plant moves towards light sources or away from light sources. Positively phototropic means it moves towards light. Most, perhaps all, plants will grow towards a light source. Plants need light energy so they have evolved to grow in the direction of the best light. Negatively phototropic means it moves away from light. Vampires are known to be negatively phototropic.
