Cell Functions
What is the primary function of the cell wall?
To provide structure and support in plant cells.
How do producers and consumers differ?
Producers make energy; consumers eat producers or other organisms.
What is the primary biomolecule in pizza dough?
Carbohydrates.
What are the outputs of photosynthesis?
Oxygen and glucose.
Name one method to estimate population sizes.
Random sampling or mark-recapture.
Which cell type is prokaryotic?
Bacteria
What would happen to producers if sunlight was reduced?
Producers would die, affecting the food web.
Why is carbon the main element in organic compounds?
Carbon can form four stable bonds.
What gas caused the balloon to expand in the respiration lab?
Carbon dioxide.
Why is carrying capacity important?
It limits population growth in ecosystems.
What are the main differences between prokaryotic and eukaryotic cells?
Prokaryotic cells lack a nucleus and membrane-bound organelles.
How does energy flow through trophic levels?
From producers to consumers and decomposers.
Which biomolecule stores genetic information?
DNA.
How do photosynthesis and respiration interact in the environment?
Photosynthesis produces oxygen used in respiration, and respiration produces CO2 used in photosynthesis.
How do limiting nutrients affect populations?
They restrict growth and reproduction.
What is the role of the cell membrane in regulating materials?
It controls what enters and exits the cell.
What is the role of decomposers in nutrient cycles?
Decomposers break down dead matter and recycle nutrients.
Why are lipids efficient for long-term energy storage?
They store more energy per gram than carbohydrates.
How do light and water affect photosynthesis?
They increase the rate of photosynthesis.
What patterns are observed in population simulations?
Populations grow, stabilize, or decline based on resources.
What happens if the cell membrane becomes impermeable to oxygen?
The cell cannot perform cellular respiration and dies.
How do abiotic factors shape ecosystems?
They determine the types of organisms that can survive there.
What happens to proteins during digestion?
They break down into amino acids.
Why is the law of conservation of mass important in photosynthesis?
Inputs and outputs have equal mass, following the law.
What strategies address population growth?
Reducing resource use, increasing sustainability.
