Why are callipares 1 cell thick?
Callipares are one cell thick to facilitate the exchange of gases, nutrients, and waste products with the surrounding environment through diffusion. This simple structure allows for efficient transport of substances within the organism.
How many layers thick is a capillary?
Capillaries are only one cell layer thick, which allows for the exchange of nutrients and gases between the blood and tissues. This thin structure promotes efficient diffusion and transport across the capillary walls.
How do unicellular organisms transport gases and nutients?
Unicellular organisms transport gases and nutrients through processes like diffusion or active transport. Diffusion allows these molecules to move across the cell membrane from an area of high concentration to low concentration. In active transport, the cell uses energy to move molecules against their concentration gradient.
What is the structure and function of an onion cell?
The structure of an onion cell includes a cell wall, cell membrane, cytoplasm, nucleus, and vacuole. The function of an onion cell is to store nutrients, provide support, and regulate the movement of substances in and out of the cell.
In the human body oxygen is absorbed by the lungs and nutrients are absorbed by small intestine. in a single celled organism this absorption diretectly involves the?
In single-celled organisms, such as amoebas, absorption of gases and nutrients occurs directly through the cell membrane via a process called diffusion. The cell membrane allows small molecules to pass through, enabling the organism to take in oxygen and nutrients from its environment. This process is essential for the cell's survival and energy production.

What cell part provides support for the cell allows gases and water to pass through and provides protection?
The cell wall is the structure that provides support for the cell, allows gases and water to pass through, and provides protection by maintaining the cell's shape and rigidity. It is found in plant cells, bacteria, fungi, and some protists.

Capillaries are only one cell layer thick, which allows for the exchange of nutrients and gases between the blood and tissues. This thin structure promotes efficient diffusion and transport across the capillary walls.
What allows nutrients to enter the cell?
cell membrane
What part of the cell allows nutrients to come in and wastes to move out?
The cell membrane is the part of the cell that controls what enters and leaves the cell. It allows nutrients to come in and wastes to move out.
How does a sponge-like fungus absorb nutrients from its environment?
A sponge-like fungus absorbs nutrients from its environment through its porous structure, which allows it to take in water and dissolved nutrients. These nutrients are then absorbed by the fungus through its cell walls and used for growth and reproduction.
How do unicellular organisms transport gases and nutients?
Unicellular organisms transport gases and nutrients through processes like diffusion or active transport. Diffusion allows these molecules to move across the cell membrane from an area of high concentration to low concentration. In active transport, the cell uses energy to move molecules against their concentration gradient.
What are four things that the cell wall allows to pass into and out of the cell?
Water, sucrose, ions, amino acids and proteins with molecular weight less than 20,000 can pass through the cell wall
What structure allows materials to enter and leave cell?
Cell membrane
How is oxygen and nutrients absorbed in a single-celled organism?
Single-celled organisms like bacteria and protists absorb oxygen and nutrients through their cell membrane via passive diffusion or active transport. The cell membrane allows for the passage of molecules such as gases and nutrients into the cell to fulfill their metabolic needs. Once inside the cell, these molecules are used for energy production and other essential cellular processes.
Which cell structure is a passageway for material provides protection and allows cell recognition?
Cell wall
What is the outside of a plant cell that provides extra support and it allows gases an water to pass in and out?
cell wall
