These are the factors needed for photosynthesis to occur (3 factors)

What is carbon dioxide, light and water

300
The slight negative charge at one end of one water molecule is attracted to the slight positive charge of another water molecule.
What is hydrogen bonds
300

This is the semipermeable barrier that protects the cell and all that is enclosed in it.

What is plasma membrane or cell membrane

300

(Fill in the blank) "Raising the temperature slightly will ____________________ the rate of a reaction A) increase B) decrease C) not change

This is what carbon dioxide enters the plant through

What is stomata

400
This property explains the ability of a water strider to walk on water
What is surface tension
400

This is a reaction in which two (2) molecules become covalently bonded to each other through the loss of a small molecule, usually water.

What is condensation reaction 

400

This compound has carbon bonded to other atoms and determines structure/function of living things

What is carbohydrates

500

This is the reaction when compounds are broken down by the releasing of water and then two (2) compounds come together to produce water

What is dehydration/synthesis reaction

500

The head of a phospholipid is __________. (answer has to do with water) 

Hydrophilic

500

Plants use this process so that they can open their stomata at night and close their stomata during the day to avoid water loss during the hot days without depleting the plant's CO2 reserves

What is CAM photosynthesis
