The (a)   controls what enters and leaves the cell helping it maintain (b)   . Homeostasis means (c)   / reached (d)   . The cell membrane is made mostly of (e)   but also has proteins that help move molecules in and out of the cell.

• cell membrane
• homeostasis
• balanced
• equillibrium
• Phospholipids

Match the following

• Proteins

• facilitate the movement of molecules in and out of the cell

• Cell membrane

• Makes up most of the cell membrane

• Homeostasis

• balanced=

  equilibrium

• Phospholipids

• controls what enters and leaves the cell

​ (a)   is the transport of substance into or out of the cell from an area of ​ (b)   concentration.

1. ​ (c)   -movement of materials from High to low concentration

2. ​ (d)   - movement of water from High to low

​ (e)   -the movement of specific molecules down from High to low, passing through the membrane using a specific carrier protein.

• Passive transport
• high to low
• Diffusion
• Osmosis
• Facilitated diffusion

Match the following

• Diffusion

• the movement of specific molecules down from High to low, passing through the membrane using a specific carrier protein.

• Facilitated diffusion

• movement of molecules from high to low concentration

• Passive transport

• movement of water from High to low

• Osmosis

• movement of molecules from high to low concentration without using energy

Spraying perfume and the smell spreading throughout the room is an example of

• Diffusion/Passive transport

• Osmosis

• Active transport

• facilitated diffusion

What direction will most of the molecules have to move through diffusion in order to achieve equal concentrations on both sides of the membrane?

• To the inside of the cell.

• To the outside of the cell.

• The molecules will move in and out because they are at equal concentrations.

• The molecules will not move.

HS-LS1-1

Hypertonic- there is more water ​ (a)   the cell, so the cell loses water and shrinks, 

• Place a cell in saltwater it will shrink

​ (b)   -the solutions are equal, so water will flow back and forth from inside to outside, outside to inside

Hypotonic-there is ​ (c)   water on the outside than inside, so the water flows in the cell causing it to swell.

​ (d)   is 100% water, no minerals or other substances in the water,so it will make the cells swell.

• inside
• Isotonic
• more
• Distilled water

Match the following

• Hypotonic solution

• water with no minerals or other substances in the water,so it will make the cells swell.

• hypertonic solution

• there is more water on the outside than inside, so the water flows in the cell causing it to swell.

• Isotonic solution

• there is more water inside the cell, so the cell loses water and shrinks,

• Distilled

• the solutions are equal, so water will flow back and forth from inside to outside, outside to inside

• A-Hypotonic

  B. Isotonic

  C. Hypertonic

• A- Isotonic

  B. Hypertonic

  C. Hypotonic

• A. Hypertonic
