You have an organism with the following characteristics - it grows as single cells. It is heterotrophic and has a cell wall that
does not contain peptidoglycan. What are the possible identities for this organism? What other information do you need to know about it in order to get a definitive identification
The Archaea are characterized as single cells. They can exihibit both the autotrophic and heterotrophic mode of nutrition. Their cell walls do not contain peptidoglycans but contain pseudo-peptidoglycans etc. Their environmental conditions also need to be known to give a definitive identification and also are their organelles membrane bound.
presence/absence of nucleus and membrane-bound organelles.
Explanation:
A unicellular organism that is heterotrophic with cell walls that lack peptidoglycan could be a yeast or an archaea.
<em>Archaea, even though could be autotrophic or heterotrophic grows as single cells and their cell walls lack peptidoglycan.</em>
<em>Yeasts represents a group of unicellular fungi. They are also heterotrophic and lacks peptidoglycan in their cells walls (they have chitin instead).</em>
In order to arrive at a more definitive identification, an information about the presence or absence of nucleus and other membrane-bound organelles will suffice.
Archaea do not have nucleus and membrane-bound organelles while yeast cells have both attributes.
Less genetic variation in the inheritance of traits causes a crops ability to be more prone to disease because there are less alleles immune to disease in the genetic pool
