Photosynthesis
What are the two types of mesophyll cells?
Palisade and Spongy
What happens during cellular respiration?
Cells break down sugar to make ATP
Define evaporation, condensation, and precipitation.
1. Evaporation - converting liquid water to gas
2. Condensation - converting water vapor to liquid water
3. Precipitation - liquid water that falls from clouds to Earth's surface.
What do carnivores, herbivores, and omnivores eat?
Meat, plants, and both
True or False - some unicellular organisms perform photosynthesis?
TRUE
Why are spongy cells loosely arranged?
What are pigments?
Chemicals that absorb or reflect light.
Water covers how much of Earth's surface? How much is in oceans?
70%, 97%
What is the difference between a food chain and a food web?
A food web is many overlapping food chains
True or False - Phytoplankton makes carbon in photosynthesis
False
Why are palisade cells packed close together?
To capture the most light
What cells do chloroplasts live in?
Mesophyll
Most of Earth's atmosphere is...
Nitrogen
What role to detritivores play in the environment?
They prevent dead stuff from piling up by decomposing dead organisms
True or False: The second trophic level is decomposers.
False
What are the 2 basic steps of photosynthesis?
1. Capturing energy from light
2. Using that energy to make sugar
What cells produce the waxy covering on the leaf and what is that covering called?
Epidermis! Cuticle!
How is phosphorus used by organisms?
Phospholipids in cell membranes and DNA
How is energy transferred from one organism to another?
Feeding Relationships
True or False - the first trophic level is primary consumers
What is the photosynthesis equation?
6CO2 + 6H2O -> C6H12O6 + 6O2
What are the 2 steps of cellular respiration? Where does each occur?
1. Glycolysis - in the cytoplasm
2. Further processing in the mitochondria
Why is Nitrogen important to all living things?
DNA and Protein
Why do you lose energy as you go up the energy pyramid?
FALSE - it ABSORBS all but green
