The rapid leaf movements resulting from a response to touch (thigmotropism) primarily involve _____.
Svetach [21]

The rapid leaf movements resulting from a response to touch (thigmotropism) primarily involve<u> potassium channels.</u>

<u />

  • Thigmotropism is a directional growth movement that develops in response to a touch stimulation through the mechanosensory system.
  • Plant biologists have also discovered thigmotropic reactions in blooming plants and fungus, while thigmotropism is often found in twining plants and tendrils.
  • A directed growth movement known as thigmotropism happens in response to touch. Typically, twining plants and tendrils that coil around supports exhibit thigmotropism.
  • The trigger for the geotropism process is gravity. A plant organ's directional response to physical contact or touch with a solid object is known as thigmotropism.
  • The induction of some pattern of differential growth typically results in this directional reaction.
  • The climbing tendrils of some plants, such the clinging fern, provide a clear illustration of this phenomena.

During which step of the water cycle does water combine with pollutants on Earth's surface?
Troyanec [42]

Compare and contrast pluripotent cells and totipotent cells
sweet [91]

Answer and Explanation:

In suspension cultures (liquid media), it has been demonstrated that single cells can regenerate to form an entire plant, and undergoes all the natural stages of embryo development.

Totipotent stem cells give rise to all types of cells including the placenta and embryo in animals.Pluripotent cells on the other hand are cells that are capable of self-renewing into the three different germ layers of an embryo forming an adult without giving rise to placenta. As the embryo grows, it develops into multipotent cells.
