What cell makes up the outer tissue layer of an organism?
The outer tissue layer of an organism is typically made up of epithelial cells. These cells are responsible for protecting the organism from the external environment and regulating the exchange of materials between the organism and its surroundings.
Where does the materials needed by cells come from?
Cells get the materials they need from the environment around them. Nutrients are obtained from food and water intake, oxygen is obtained through breathing, and other necessary molecules are absorbed through cell membranes. The cell then uses these materials to carry out various functions and processes to sustain life.
What are the three phases of transferring gases between the environment and the cells?
The three phases of transferring gases between the environment and the cells are ventilation (breathing air in and out of the lungs), gas exchange (oxygen and carbon dioxide exchange between the lungs and blood), and circulation (transporting oxygen to the tissues and removing carbon dioxide).
What is the effects of the exchange of oxygen and carbon dioxide between internal leaf cells and the external environment?
The exchange of oxygen and carbon dioxide between internal leaf cells and the external environment is crucial for photosynthesis and respiration. During photosynthesis, cells take in carbon dioxide and release oxygen, while during respiration, cells take in oxygen and release carbon dioxide. This exchange allows plants to produce energy and oxygen while removing carbon dioxide from the air.
What part in cell works regulates flow of materials into and out of cells?
The cell membrane, also known as the plasma membrane, regulates the flow of materials into and out of cells. It is selectively permeable, allowing certain molecules to pass through while blocking others, thus controlling the exchange of substances between the cell and its environment.
What is the main reason cells exchange materials with the environment around.?
to get rid of wastes and take in nutrients
Which materials are exchange between the blood and the body cells?
capillaries
Why can smaller cells exchange materials faster than larger cells?
Because the materials can go through the small cell faster

What vessels exchange materials with the extra cellular fluid and the blood?
Capillaries. Since they are only once endothelial cell thick, they can exchange gas, nutrients, and waste across their membrane. Capillaries in the brain have endothelial cells close together to onyl allow a slecetive exchange of materials, while capillaries in the kidney or liver have gaps between the endothelial cells to allow the exchange of a lot of materials.
What most important thing happens in the capillaries?
materials exchange between blood cells and blood

Why are cells of the spongy layer packed so loosely together?
All plant cells respire all of the time and need to exchange gases. The main gas exchange surface in plants are the spongy mesophyll cells in the leaves. Leaves have a huge surface area, and the irregular-shaped, loosely-packed spongy cells increase the area for gas exchange even more.
What structures are present in protists that are also present in human cells?
Both protists and human cells contain membrane-bound organelles such as the nucleus, mitochondria, endoplasmic reticulum, and Golgi apparatus. Additionally, both cell types have a plasma membrane that regulates the exchange of materials with the environment.
