Adhesion is:

Remember: "ad" =towards/ opposing

"hesion"=uniting/ sticking together

• Water molecules sticking to other molecules; unlike molecules.

• Water molecules repelling other molecules; unlike molecules.

• Harllee molecules sticking to other molecules; weird molecules.

• Water molecules attacking other molecules, unlike molecules.

Which twins are a good example of Adhesion ?

Remember: "ad" =towards/ opposing

• 

Capillary Action is:

• The combination of adhesion and cohesion opposing each other to dry up water up the xylem from the roots to the leaves

• The combination of snakes and cats working together to move water

• The combination of adhesion and cohesion working together to move water up the xylem from the roots to the leaves

• When Ms. Harllee goes to Pilates Class and works out.

What is Cohesion?

Remember: "Co" =join/ common

"hesion"=uniting/ sticking together

• Water molecules sticking to different types of molecules

• Water molecules sticking to plants and their leaves

• Water molecules sticking to other water molecules, like molecules

• This is how Chick-Fil-A makes their nuggets

What are Guard Cells?

• One on either side of each stoma. Controls if the stomata are open or closed

• One on either side of each molecule. Controls if the molecules are open or closed

• One on either side of each stoma. Controls if the stomata are awake or asleep

• One on either side of Murphy Middle. Controls if the bathrooms are open or closed

What is Phloem?

• A vascular tissue that carries chlorophyll to the roots and back up to the plant when needed.

• A vascular tissue that carries cellulose to the roots and back up to the plant when needed.

• A vascular tissue that carries glucose to the roots and back up to the plant when needed.

• A luxury brand of tissues from Gucci

What are Stomata?

• Tiny openings in the skin of a leaf that allows gas exchange and allows water to ENTER the plant for transpiration

• Tiny openings in the skin of a leaf that allows bugs and dirt to EXIT the plant for transpiration

• Tiny openings in the skin of a leaf that allows gas exchange and allows water to EXIT the plant for transpiration

• A really rare type of pasta noodles from Italy

What is Transpiration?

• The evaporation of water from a leaf. It allows for the continuous movement of water and allows plants to get rid of extra water

• The evaporation of water from the roots. It allows for the continuous movement of water and allows plants to get rid of extra water

• What pinterest moms do in yoga class

• The evaporation of water from a seed. It allows for the no movement of water and allows plants to get lots of extra water

What is Tugor Pressure?

• That feeling you get when a test is coming up

• Glucose pressure in a plant

• Chlorophyll pressure in a plant

• Water pressure in a plant
