TYPES OF ORGANISMS:
• Autotrophs can make their own food using
energy from sunlight.
Example: green plants and some bacteria
Heterotrophs get energy by consuming other
organism
Example: animal, fungi, and most bacteria
Photosynthesis
•Autotrophs/ producers undergo photosynthesis
•Process of converting solar energy to chemical energy
•Produces glucose (food) to generate energy (ATP)
•Occurs in chloroplast within the leaves
reactants
products
Six molecules of carbon dioxide react with six
molecules of water to form 1 molecule of glucose
and six molecules of oxygen
How many molecules of carbon dioxide would be
needed to produce 4 molecules of sugar?
4 x 6= 24
Chloroplast
(solar panel organelle)
•Produces food & stores energy
•2 types of reactions- light dependent and light independent
(Calvin cycle)
•Contains pigment chlorophyll (green)
•Absorbs most of the colors in electromagnetic spectrum
except reflects green & yellow wavelengths
•Contains chlorophyll a and chlorophyll b
Chloroplast
(solar panel organelle)
•Light dependent (photosystem I)- water and light react with
NADP+ and ADP to produce oxygen, ATP & NADPH (occurs in
thylakoids)
•Light independent or Calvin cycle (photosystem II)- carbon
dioxide, ATP and NADPH react to form glucose, ADP and
NADP+ (occurs in stroma)
Organs of the plant
Roots- absorbs water, anchors plant in ground
Stem- transports water and nutrients around
plant
Leaf- site of photosynthesis
Contains stoma- holes where gases pass through
Greenhouse Effect
CO2 is released in the air and accumulates
around the circumference of the earth
It is able to trap (absorb) light from the sun that
isn’t reflected back
This helps to maintain a balanced temperature
on the earth (homeostasis)
Global Warming theory: Too much CO2 increases
the earths temperature

 ATP releases energy stored in a
high energy chemical bond by
removing the phosphate and
becoming ADP (ATP to ADP)
 The reverse rxn stores nrg (ADP to

Bellchallenge
Write the question and
answer
ATP is being synthesized by adding one more
phosphate group. This is an endergonic
reaction that stores energy. Also ATP a
phosphate group is being removed from ATP.
This is an exergonic reaction that releases
energy.

Write the question and
answer
Many factors can affect the rate of
photosynthesis. Any variation of the three
reactants of photosynthesis (light, water and
CO2) could alter the rate of photosynthesis.
Temperature can also affect the rate.
