The Sun evaporates water from lakes and
Photosynthesis occurs in two stages:
oceans. As the air rises, it cools. The water
vapor condenses into tiny droplets of water
1) Light Dependent Reaction
The droplets crowd together and form a
cloud Wind blows the rain towards the land.
a. Occurs in the thylakoid
The tiny droplets join together and fall as
precipitation to the ground The water soaks
b. Uses: sunlight and Water
into the ground and collects in rivers/oceans
The water cycle that never ends has started
c. Produces: ATP, NADPD and
again!
O2
2) Light Independent Reaction
Which cycle is demonstrated in the picture
above? Carbon cycle
a. Occurs in the stroma
What are the contributors of carbon dioxide to
the atmosphere? Automobiles, factories, animal
and plant respiration, decomposition
b. Uses ATP, NADPD and CO2
How is the carbon dioxide removed from the
atmosphere? Photosynthesis
c. Produces: sugar
List factors that may affect the rate of
photosynthesis:
light, water, nutrients
What are the consequences of increased carbon
dioxide levels in the atmosphere? Global
warming (melting ice caps, habitat changes,
competition)
Nitrogen Cycle:
gravitropism
What organisms are responsible for putting
Nitrogen into a usable form for plants and
animals? bacteria
Identify 4 characteristics of Plants:
Autotrophic, cell walls: cellulose, multicellular,
producers, eukaryotic
Differentiate between nitrification and
denitrification.
Nitrification : Bacteria in soil take up ammonia and
oxidize it into nitrites and nitrates and plants use it
to create amino acids Denitrification: Process of
how nitrogen is returned to the atmosphere when
bacteria break down nitrates and release nitrogen
gas
The turning or bending movement of a plant
toward or away from a stimulus is called
tropism
Identify each type that is occurring:
Phototropism (positive)
Kingdom Plantae
thigmotropism
Identify a function of each of the following
major mineral nutrients required by plants:
Nitrogen
Promotes growth of green plant
parts, part of proteins, DNA and
chlorophyll
Potassium
Active transports, enzymes and
opens stomata
Phosphorus ATP, ADP and cell membrane
Calcium
Part of cell wall and membrane
activity
Magnesium Chlorophyll, enzyme activation
Sulfur
Part of proteins, needed for cell
respiration
Carbon
Need for light independent
reactions of photosynthesis
Pigments in a plant are used to convert lgiht
energy to chemical energy.
Identify the color of each of the following
pigments:
Chlorophyll: green
Xanthophyll: yellow
Carotene: orange
Draw a concept map organizing the
classification of Plants. Use the following
words:
Gymnosperms
seeds
Vascular
Plants
nonvascular
angiosperms
seedless
