Homeostasis and Cellular Transport

Recognize and explore how cells of all organisms undergo similar processes to maintain homeostasis, including extracting energy from food, getting rid of waste, and reproducing. (SC.6.L.14.3 - DOK 2)

Homeostasis and Cellular Transport

Homeostasis describes the stable internal environment that all organisms (and cells!) must maintain, regardless of what is occurring outside of them, in order to survive.
In order to maintain homeostasis, cells must take in materials, like nutrients and gasses, and release others, like waste.
The cell membrane is responsible for controlling what moves in and out of a cell and is selectively permeable, which means some things can move in and out, but not all.
There are two types of cellular transport: active and passive. Passive transport does not require energy, while active does.
Passive transport can happen by diffusion, osmosis, or facilitated diffusion.
Active transport can happen through protein pumps, endocytosis, or exocytosis.

Multiple Choice

Homeostasis is the ability of living things to maintain internal balance. Which of the following is an example of homeostasis?

A boy's nervous system causes him to pull his hand away from a hot pot.

A dog's reproductive system enables the dog to produce offspring.

A plant cell takes in more water when it becomes too dry.

A virus infects a human cell and causes yellow fever.

Multiple Choice

The diagram identifies four structures in a plant cell. Which structure controls what enters and leaves the cell?

cell membrane
