Describe in sentences how having organelles is important for creatures to be multicellular. (ex. even though
prokaryotic cells evolved first, why have they never evolved to form a multi celled creature?)
The mitochondria and chloroplast have small their own circular
chromosomes, which is part of the evidence suggesting these organelles
may have long ago been free-living prokaryotes that were brought into the
cell in vesicles but not digested.
True
False
A cell physiologist treats a cell with a chemical that prevents entry of amino acids. Based on your understanding of the different cell organelles, predict which organelle will be affected the most.
