Pavlova-9 [17]

Given what we know, we can confirm that among the options listed, the more appropriate example of positive phototropism is the <u><em>houseplant </em></u><u><em>growing towards the </em></u><u><em>window</em></u><u><em>. </em></u>

<h3>What is positive phototropism?</h3>
  • This is a photosensitive reaction that occurs in plants.
  • Positive phototropism is described as the growth of plants towards the source of light.
  • While negative phototropism is when the plants lean away from the light.
  • Sunflowers and bananas, which lean towards the sun as they grow, are prime examples of positive phototropism.

Therefore, given the definition of positive phototropism as the growth of an organism towards a source of light, we can confirm that the option stating that the <u><em>houseplant </em></u><u><em>grows towards the window</em></u> is the best example of this concept, given that the window is the source of light for the plant.

DiKsa [7]

Answer:

The answer is b. Both of them are characterized by selective permeability.

Explanation:

  • Option a. states that both, the nuclear and the cell membrane have two layers. This is only true for the nuclear membrane that consists of two lipid bilayers whereas the plasma membrane only contains one layer.
  • c. Only the nuclear membrane has nuclear pores that connect the two bilayers. The pores act as protein channels or passages that allow transport of materials. The cell membrane does contain channel proteins or transmembrane proteins but not protein channels.
  • d. The nuclear membrane separates nuclear contents from the cytoplasm whereas the cell membrane separates cellular contents from the extracellular environment.
