1. BIOLOGY
Photosynthesis

2. A) ATP – The energy molecule
ATP – adenosine triphosphate
Function
ATP is used as the molecular energy currency, the energy molecule for all cells
ATP is a special type of nucleic acid, and is based off the nucleotide Adenine, thus the molecule is a nucleotide
ATP is an organic molecule used to store chemical energy, stored in the bonded phosphates (just like a AA batery)
Produced during Cell Respiration
Structure A P P P
Ribose

3. ATP  ADP Cycle ATP is formed by an enzyme called ATP Synthase
Energy is released from this molecule by breaking the bond between the last two phosphates, by a process called hydrolysis using ATPase

5. B) Plant Structures Vascular Tissue
Xylem- moves water and nutrient up the body of the plant
Phloem - moves water and sugar down to the roots of the plant
xylem up, phloem down
Lets draw a diagram of a tree, on the board

6. Structure of a Leaf (Cross-Section)
Lets draw a diagram of a leaf, on the board

7. Cuticle- waxy coating that helps prevent water loss from leaf
Epidermis-skin of the leaf
Palisade Mesophyll- sight of photosynthesis inside the plant, hold chloroplasts
Spongy Mesophyll- predominant water storage in leaf

8. Stoma ( Stomate or Stomata) - little mouth like structure on the bottom of a leaf that allows for the gas exchange in the leaf
-formed by two guard cells
- Water loss from a leaf is called transpiration

9. C) Photosynthesis
Process that takes inorganic compounds and converts them to organic sugars using the sun’s energy
[ Reactants------]

Two Reactions that make up photosynthesis
Light Dependent Reaction- Stored the energy from the sun in the form of ATP ( AA Batter) and NADPH ( C Battery)
-occurs in the thylakoid membrane
Dark Independent Reaction ( Calvin Cycle) –Uses the batteries charged in the light reaction to turn CO2 into glucose and releases oxygen
- occurs in the stroma of the chloroplast

14. Factors affecting photosynthesis
Temperature – warmer the air the faster photosynthesis happens
Light Intensity – when light angles get to low, the green pigment cannot absorb enough energy, chlorophyll disappears and leaves change color
Water supply- if conditions are dry, photosynthesis stops
Carbon Dioxide Concentration- can limit supply of carbon dioxide
Humidity- can prevent movement of water in plant
