Paramecium obtain oxygen through diffusion across their cell membrane. This process allows oxygen to pass from the surrounding water into the cell where it is used for cellular respiration to produce energy.
Nutrients and oxygen pass into body cells through a process called diffusion. This process allows these substances to move from areas of higher concentration (outside the cell) to areas of lower concentration (inside the cell) through the cell membrane. Once inside the cell, nutrients and oxygen are utilized for various cellular functions.
oxygen, carbon dioxide, and water
Plasma membrane
Small molecules, such as water, oxygen, and carbon dioxide.
Cell membrane============================by johan9408Substances produced in a cell and exported outside of the cell would pass the endoplasmic reticulum and Golgi apparatus
All particles trying to get into the cell must get through the cell membrane. The cell membrane is selectively permeable, which means that it can select what goes in and what goes out. The structure of a cell membrane is called a lipid bilayer, which is two layers of phospholipids.
cell membrane
Although the cell wall is tough, many materials, including water and oxygen, can pass through easily.
Oxygen
It keeps the cell in shape, works as a protection and lets oxygen and nutrition pass into the cell
Substances produced in a cell and exported outside of the cell, such as proteins, hormones, and neurotransmitters, would pass through the Golgi apparatus. The Golgi apparatus functions to process, modify, and package these substances before they are transported to their final destination outside the cell.
Small, non-polar molecules like oxygen, carbon dioxide, and water can easily pass through a cell membrane.
Substances produced in a cell and exported outside of the cell would pass through the cell's plasma membrane via a process called exocytosis. Exocytosis involves the fusion of vesicles containing the substances with the plasma membrane, allowing the substances to be released outside the cell.
Oxygen is much smaller than a protein.proteins are too largeDifference in size
