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.

Answer:
c) Ribosomes on the rough endoplasmic reticulum; Golgi apparatus
Explanation:
Endoplasmic reticulum, a member of endomembrane system. If it contains ribosomes on their surface, they are called Rough Endoplasmic Reticulum (RER). RER is the site for protein synthesis.
Newly formed protein undergoes modification, one such modification is the addition of carbohydrate side chains to form glycoprotein. The protein then moves to the Golgi for modification.
Answer:
Both the nature of the gene and its environment can influence the mutation rate.
Explanation:
Mutations are caused by environmental factors known as mutagens.
Types of mutagens include
- radiation,
- chemicals, and
- infectious agents.
C) the phases are there for the cell to grow and mature properly ( much like a human) - if they don’t grow properly they won’t be able to reproduce.
