Prokaryotic flagella allow the cell to utilize oxygen more efficiently.
Yes it does
A cell will only freely allow in very small molecules such as oxygen, water and carbon dioxide. Larger molecules such as sugars must be transported into the cell through special channels using energy.
cardiac cells
The cell membrane, which is a structure surrounding the cell, controls the passage of nutrients, water, and oxygen in and out of the cell. It acts as a selective barrier, allowing specific molecules to pass through via processes like diffusion or active transport.
Plasma membrane
Cell membranes usually allow water, gases (such as oxygen and carbon dioxide), and small uncharged molecules to enter a cell. Larger molecules or charged ions may require specific transport proteins or channels to cross the membrane.
The oxygen produced by chloroplasts during photosynthesis passes out of the cell primarily through small openings called stomata. These pores are located on the surface of leaves and allow for gas exchange, enabling oxygen to diffuse into the atmosphere while also facilitating the intake of carbon dioxide for photosynthesis. Additionally, oxygen can also diffuse directly through the cell membrane.

The function of the red blood cell is to carry oxygen to body tissues. Its structural features that allow this include the hemoglobin molecule, its anuclear state, and its biconcave shape.
The cell membrane is partially permeable, to allow nutrients like glucose and oxygen to enter the cell, and for waste products (eg. CO2 and urea) to exit the cell. It does not hold the cell together; this is carried out in plant cells by a cellulose cells wall.
