chapter 9 plants bio

• what is the equation for photosynthesis?

  6CO2 + 6H2O + light energy -> C6H12O6 + 6O2
• upper epidermis

  skin/ protection
• pallsade

  chloroplast/photosynthesis
• spongy parenchyma

  air spaces
• lower upper dermis

  skin
• the stomata allows

  O2 and CO2 through
• gaurd cells function

  Control the opening and closing of the stoma
• the veins pholem and Xylem

  Transfer nutrients
• how is glucose made and where

  glucose is made by the chloroplast in the Palaside tissue cells (leaf)
• Cellular respiration formula

  Photosynthesis backwards
• water loss in plants is called

  Transpiration
• turgour pressure in plants means

  lots of H2O available for vacuoles equals high water pressure
• when a plant has lots of water the gaurd cells what

  The guard cells swell and push the lower upper dermis cells aside to make the stoma open
• when the plant has low H2O at night

  Means it has low, turgor pressure and the guard cells will not swell which means the stoma closes and water is not lost
• turgor pressure in roots is called

  Route pressure
• xylem goes which direction

  pushes the water up
• H2O first enters by

  the root hairs
• what is capillary reaction?

  How water flows in straws.

  Cohesion water molecules stick to themselves

  Adhesion water molecules stick to other surfaces
• xylem is what and pholem is what

  xylem is water, and phloem is food
• pholem moves sugars _____ and why

  down. the concentration gradient from the leaves( [high] to the roots [low]
• what is phototropism?

  Growth or movement of an organism in response to light.
• why does phototropism happen? and how?

  To maximize photosynthesis, the tip of the plant makes a hormone called oxen, and they caused the cell on the shady side to elongate (grow longer and faster)
• auxins are made, where

  They are made in the tip and accidents travelled to the Shadyside results in cell elongation. and the funny cells stay the same size.
• what is Gravitropism?

  The growth of a plant response to gravity
• why does Grava tropism happened?

  Due to auctions in the shoot tip, and also in the root tip
• shoots always grow

  against the force of gravity
• roots always grow

  With the force of gravity (gravatropism)
