Answer:
d. Fungi have cell walls made of cellulose.
Explanation:
The cell wall is an extracellular envelope present in all vegetables and some bacteria, fungi and protozoa. Its composition varies according to the habit of each organism before the evolutionary and adaptive processes. This structure precludes morphological changes of organisms, due to its semi-rigid character, that is, cells cannot change shape as a result of spatial impediment limited by the rigidity of the cell wall.
In plants, the cell wall is basically composed of the cellulose polysaccharide, which forms the cellulosic wall. In most fungi, the wall is formed by chitin. Therefore we can state that the statement that does not describe a way in which fungi differ from plants, among the options given is "the fungi have cell walls made of cellulose."
The scenario above tell us that the effects of a neurotransmitter is based on the properties of the receptor to which they bind more than the neurotransmitter. Some neurotransmitters bring about stimulation when the bind to receptors while others brings about inhibition. The effect of a neurotransmitter on a receptor depends on the properties of that receptor.
