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.
What else can I help you with?
Which part of an animal cell lets food water and oxygen pass in and out?
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.
What substances can easily pass through a cell membrane?
Small, non-polar molecules like oxygen, carbon dioxide, and water can easily pass through a cell membrane.
Why can oxygen diffuse across a cell but a protein cannot?
Oxygen is much smaller than a protein.proteins are too largeDifference in size
How does euglena get oxygen?
Euglena obtains oxygen through a process called diffusion. It absorbs oxygen from the surrounding water through its cell membrane, which allows gases to pass in and out of the cell. This process enables euglena to survive by taking in the oxygen it needs for respiration.
How does the Oxygen get from the interstitial fluid to the inside of the cell?
Oxygen diffuses from the interstitial fluid into the cell through the cell membrane. This process occurs due to a concentration gradient, where oxygen moves from an area of higher concentration (interstitial fluid) to an area of lower concentration (inside the cell). Once inside the cell, oxygen is used in cellular respiration to produce energy.
What cell part can oxygen pass directly through?
cell membrane
Can water and oxygen pass through the cell walls?
Although the cell wall is tough, many materials, including water and oxygen, can pass through easily.
What part of the cell must nutrients pass through to get into the cell?
The Cell Membrane
What specific substances can pass through a cell membrane by diffusion?
Oxygen
Which part of photosynthesis is oxygen produced?
the cell
Which part of an animal cell lets food water and oxygen pass in and out?
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.
What function the cell membrane in all cells?
It keeps the cell in shape, works as a protection and lets oxygen and nutrition pass into the cell
What part of the cell do materials pass through to get into and out of a cell?
By the cell membrane located on the outside of an animal or plant cell.
What part of the cell membrane allows small molecules to pass through?
the cell membrane
What substances can easily pass through a cell membrane?
Small, non-polar molecules like oxygen, carbon dioxide, and water can easily pass through a cell membrane.
Why can oxygen diffuse across a cell but a protein cannot?

True or false water carbon dioxide and oxygen can pass through the cell wall?
true
