Ecology
Four macromolecules & function?
Monomers of protein? nucleic acids?
proteins – repair cell and transport , nucleic acids - DNA, lipids – store energy and make cell membranes, carbohydrates – store energy
P: Amino acids
NA: nucleotides
Describe how plant and animal cells are different in structure and function.
Plant cells have cell walls, chloroplasts, and large central vacuoles (NO CENTRIOLES, NO LYSOSOMES). Animals cells have centrioles, lysosomes ( NO CELL WALLS, NO CHLOROPLASTS)
What is the outcome of cellular respiration? Give the molecular equation
glucose and oxygen yields carbon dioxide and water.
C6H1206 + 6O2 🡪 6H20 + 6CO2 + Energy
What is the pigment found in green plants? In what organelle is it found?
chlorophyll, chloroplast
What is trophic level?
As trophic level increases, what happens to energy first received by producers?
Steps of a food chain or food web
Decreases by 90%
What are the two criteria that eukaryotes contain that prokaryotes do not?
contain nucleus and membrane bound organelles
What is the outcome of glycolysis? What does it make? Where does it take place?
Glycolysis is the breakdown of glucose produced during photosynthesis to produce 2 pyruvic acids. It takes place in the cytoplasm
What happens during the light reaction? What are the reactants? What are the products?
Plant uses light to split water, giving off oxygen that excites electrons. Reactants: light, water, ADP, NADP. Products: oxygen, H+, electrons, NADPH, ATP
What is commensalism?
Mutualism?
Parasitism?
M: Both benefit off of each other
P: One benefits; other is harmed
What is a prokaryote? eukaryote?
prokaryote (bacterial cell) not containing a nucleus. Eukaryote – (plant or animal cell) contains a nucleus
20.) What is the outcome of Krebs Cycle? Electron Transport Chain? Where do these take place?
CO2
ATP
Mitochondria
What happened during the dark reaction? What are the reactants? What are the products?
Plant uses CO2 to make sugar. Reactants: NADPH, ATP, Carbon dioxide. Products: sugars, NADP, ADP
Exponential growth?
L: growth slows or stops following exponential growth at the population's carrying capacity (S curve)
E: Growth rate proportional to size of population (J curve)
Be able to describe all the organelles in regards to their structure and function.
QUIZLET
What is the outcome of photosynthesis? Give the molecular equation
Carbon dioxide and water in the presence of light yields sugar, water and oxygen
6H20 + 6CO2🡪 C6H1206 + 6O2
What is a limiting factor?
Density dependent?
Density Independent?
Any factor that limits the size of a population
DD: competition, food, migration, disease, predation, parasites, biotic factors
DI: extreme weather, pollution, fire, climate change
What is ATP? What is its importance?
ATP=adenosine triphosphate. It is the energy molecule in cells
