Water Chemistry
What is the bond between different water molecules?
Hydrogen bond
CO2 and water move through this kind of transport?
passive transport
Picture on white board :)
phospholipid
active transportation where waste is removed from the cell
exocytosis
3 inputs into a plant
sunlight, water, minerals, CO2
water sticking to water=
water sticking to other substances=
water going against gravity=
cohesion
adhesion
capillary action
What is the form of energy in cells that is used in active transport
ATP
the cell membrane is made by a :
where the heads are hydro:
phospholipid bilayer
phillic
produce large surface areas
root hair
soil types with smaller particles allow more or less water through? why?
less, because there is more opportunities for adhesion to occur. DENSITY
Water moves through simple or facilitated diffusion?
active or passive
facilitated, passive
what is osmosis? Active or Passive?
movement of water- passive
a solution with high solute concentration
hypertonic
"cell eating"
endocytosis
what is the different between xylem and phloem?
direction and substance moved
When a solution is hypertonic, what would happen to a cell placed within it?
water would leave the cell and the cell would shrink
the movement of water into a cell to the point where it can burst is from what kind of solution?
hypotonic
the part of a plant that takes up water
xylem
a membrane that only allows some molecules to pass through it
semipermeable/selectively permeable
what percent of air space do plants need to properly grow?
50% air space
what property of water allows them to have all its characteristics?
polarity
what type of transport moves nutrients into the root hair?
protein pumps
The "flag" on the cell to show what it is:
Carbohydrate chains
Protein that moves water with the concentration gradient
aquaporin
When would a stomata not open?
When it is to hot or dry
