Which characteristic distinguishes fungal cells from plant cells
sertanlavr [38]

Answer: Feeding behaviors, trophic levels, cell wall composition, and their organelles distinguish fungi from plants.

Explanation:

While plants and fungi are both eukaryotes, they differ in terms of feeding behaviors, trophic levels, cell wall composition, and their organelles.

  • Cell walls: both are non-chain polysaccharides (sugars) that function as structural support; yet fungal cell walls are composed of chitin while plant cell walls are made up of cellulose

  • Feeding: fungi secrete compounds that digest their food sources before they can take in nutrients and they store food as <em>glycogen; </em>while plants do not require a means of pre-digesting food and store their food as <em>starch.</em>

  • Organelles: plant cells contain <em>chloroplasts</em>, small green structures with chlorophyll that causes their characteristic coloration. Unlike plants, fungi do not photosynthesize to make their own food or contain chloroplasts.

  • Trophic level: are strictly <em>heterotrophs or decomposers, </em>depending on other organisms for survival. Their chloroplasts enable them to carry out photosynthesis, thus they are <em>autotrophs or producers. </em>

DochEvi [55]
<h3>Answer:</h3>

Enzymes functions in a specific temperature range.

<h3>Explanation:</h3>
  • Enzymes are biochemical catalysts whose function is to speed up the rate at which chemical reactions occur.
  • Enzymes work best at a specific range of temperatures known as optimum temperature.
  • Low temperatures below optimum levels deactivate the enzyme and thus lowering the rate of enzyme activity.
  • Extreme temperatures, on the other hand, denatures the enzyme altering enzyme's active sites making it difficult for substrates to fit.
