Materials can move in and out of animal cells through one of two reasons: Passive transport or active transport. Passive transport happens naturally and requires no energy on the part of the cell. It usually happens through osmosis, diffusion, or facilitated diffusion. Active transport involves endocytosis, exocytosis, or molecules moving from a low concentration to high concentration. Active transport requires energy.
What else can I help you with?
Is the endoplasmic reticulum found in plant or animal cells cells?
Both, the cells use it to move materials around the cell
What happens when blood in capillaries flow the past cells?
Materials needed by the cells move from the blood into the cells, and waste materials move from the cells into the blood.
What types of cells contact to move an animal?
Muscle cells move bones which move animals.
What move materials past cells or move cells?
Blood moves materials past cells, allowing for diffusion. It also moves cells themselves to places they are needed, as with immune system cells.
What do most of the food and waste materials that move into and out of a cell pass through?
They pass through the cell walls and or membranes depending on wether or not its a plant or animal cell. Animal cells have only membranes. Plant cells have both.
Why do animal cells move?
Because they are travlers
What type of cells contracts to move an animal cell?
muscle cells...
What types of cells contracts to move an animal?
muscle cells...
The way most materials move in and out of cells?
fibrous
What is the way most materials move in and out of cells?
diffusion
Protein 'tunnels' between animal cells through which materials can pass from cell-to-cell?
For animal cells it is called a "gap junction"
Do all animal cells move independently?
No, not all animal cells move independently. Some animal cells are part of tissues and organs that are anchored in place and do not move on their own. Other cells, like immune cells and muscle cells, have the ability to move independently within the body.
