Homeostasis Key Terms

What is diffusion?

• movement of water ONLY, from high to low concentration area

• movement of molecules/substances from a highly concentrated area to a low concentrated area.

• distribution of chemicals or substances around the body to maintain homeostasis.

The need for a cell to maintain internal balance is called

• osmosis

• diffusion

• synthesis

• homeostasis

What is selectively permeable cell membrane mean?

• The cell/plasma membrane allows molecules to come in and out of the cell but NOT all.

• The cell or plasma membrane allows all substances to come inside of the cell.

• The ability of the plasma membrane to regulate or control what substances need to come in and out of the cell

What is cell/plasma membranes' role in maintaining homeostasis in the trillions of cells in your body?

• The cell membrane allows substances from the food to go inside of the cells.

• The cell membrane blocked the substances that harm the cells.

• The cell membrane moves extra substances from inside to outside of the cells.

The movement of all substances into our cells and the exchanging of gases during breathing is called

• photosynthesis

• cellular respiration

• cellular transport

Is a type of diffusion that refers ONLY to the movement of water in and out of the cell.

• osmosis

• diffusion

• synthesis

• passive transport

The normal movement of molecules from highly concentrated to the low concentrated area is called

• passive transport

• active transport

• cellular transport

• cellular respiration

Which cellular transports are passive transport?

• osmosis

• diffusion

• active transport

• facilitated diffusion

This cellular transport is against the concentration gradient, meaning, it happens when ATP energy help during the movement of molecules from low concentration to a highly concentrated area.

• passive transport

• active transport

• simple diffusion

• facilitate diffusion

It is a type of passive transport, meaning the movement of molecules is still from high to low concentration areas. However, a protein membrane helps in the channeling of molecules.

• simple diffusion

• passive transport

• active transport

• facilitated diffusion
