Which stucture is responsible for allowing materials into and out of an animal cell?

Hey there!

The answer to your question is a CELL MEMBRANE.

Hi!

There are two types of transport of matter through the animal cell:

1. Passive transport, which is composed of:

  a. diffusion

  b. facilitated diffusion

  c. osmosis

  In passive transport,  matter through cell membrane is moving around using the process of equalizing the concentration in the environment.

2. Active transport, which is composed of:

  a. Na-K pump

  b. endocytosis

  c. egsocytosis

  Active transport is based on transport of macromolecules and transport with energy consumption.

Hope this helps!

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
