Answer:
In animals, the process of respiration is aerobic respiration, exchange of gases takes place ( carbon dioxide leaving the cell, oxygen entering)
Single cellular organisms can exchange gases directly across their cell membrane through the process o diffusion.
Large animals cannot maintain gas exchange by diffusion across their outer surface. A respiratory surface is covered with thin, moist epithelial cells that allow oxygen and carbon dioxide to exchange. Those gases can only cross cell membranes when they are dissolved in water or an aqueous solution, thus respiratory surfaces must be moist.
Explanation:
Eukaryotic cells have specific membrane bounded organelles to perform various specific functions.
Eukaryotic cells are cells that have a true membrane-bound nucleus and other membrane bound organelles (organized and specialized structures) that perform various functions within the cell. The organelles include; nucleus (the most important organelle and the control center of the cell), ribosomes (which arranges enzymes and other proteins based on the information found in the DNA code), endoplasmic reticulum (which is the site of cellular chemical reactions), Golgi apparatus, vacuoles (which serves as temporary storage sites), lysosomes, and mitochondria (which is responsible for making the cell’s main energy-carrying molecule).
