No! It actually does not, regardless of some beliefs.
I hope this helps! Please give brainliest if possible. ^^
Unicellular organisms are devoid of circulatory systems and will be found living in moist or watery environments to facilitate uptake of nutrients and gases and expulsion of waste by the process of diffusion.
Their cell is structured such that it can engage in direct exchange of substances with its environment. Water serves as the perfect medium or environment through which this exchange can occur.
Gases and nutrients simply diffuse into the cell or are moved into the cell by means of active transport or phagocytosis.
It’s called a branch point, represents where a single lineage evolved into a distinct new one.
Of the list shown in the image, the function of proteins in living cells are: they transport oxygen in the blood of vertebrates, they play a key role in moving materials within cells, they help the body to recognize and destroy foreign microbes and cancer cells, they catalize chemical reactions.
<h3>What are proteins?</h3>
Proteins are macromolecules made up of linear chains of amino acids that are synthesized by ribosomes using mRNA molecules as templates. they have different functions since they are present in enzymes, hormones, transport proteins and also as a structural part.
Therefore, we can confirm that of the list shown in the image, the function of proteins in living cells are: they transport oxygen in the blood of vertebrates, they play a key role in moving materials within cells, they help the body to recognize and destroy foreign microbes and cancer cells, they catalize chemical reactions.
