Vocabulary
__________________ cells have no nucleus and no membrane-bound organelles
What are prokaryotic?
These organisms derive their energy from chemical compounds
What are chemoautotrophs?
What is 'remove/sequester?'
All cell types contain: ___________________
What is DNA, ribosomes, cell membranes, and cytoplasm?
These organisms cannot make their own food and must consumer other organisms for energy
What are heterotrophs (consumers)?
____________________ is the process by which autotrophs use light energy to convert CO2 and H2O into glucose and oxygen
What is photosynthesis?
These organisms are made up of larger, more complex cells and can be unicellular or multicellular
What are eukaryotes?
____________________ is the process by which autotrophs convert gaseous carbon into a solid, accessible form of carbon
What is carbon sequestration?
_______________ organisms have small, circular strands of DNA called plasmids
These organisms derive their energy from light
What are photoautotrophs?
____________________ are capable of making their own food
What are autotrophs (producers, primary producers)?
This is the most common photosynthetic pigment used by terrestrial plants
What is chlorophyll?
Cell membranes are made up of mostly this biomolecules
What are lipids?
_______________________ cells have DNA in the form of large, condensed chromosomes
What are eukaryotic?
__________________ organisms drift through the water column without expending any energy swimming
What are planktonic organisms?
_________________ organisms live on or in the substrate at the ocean floor
What are benthic organisms?
On the board, write the full equation for photosynthesis and label the reactants and the products
Answer on board
These are the major biomolecules that make up all living things
What are 1) proteins, 2) lipids, 3) nucleic acids, and 4) carbohydrates?
Organisms that rely on the environment to maintain their internal temperature are called ______________________
What are ectotherms?
These organisms cannot regulate their temperature and have an internal body temperature that fluctuates (is not stable)
What are poikilotherms?
This is a definition of a 'decomposer' and two examples of organisms that are decomposers
What is 'any organism that feeds on dead and decomposing organic material and recycles those nutrients back into the surrounding environment; most fungi and many bacteria?'
On the board, write the full equation for aerobic cellular respiration and label the reactants and the products
Answer on board
Briefly describe the difference between an osmoconformer and an osmoregulator
What is 'osmoconformers do not control their internal concentrations of salt and water so these conditions will conform to whatever the conditions of the surrounding water are; osmoregulators use energy to control their internal salt and water concentrations and make sure they are different from the surrounding water?'
These organisms always maintain a stable, consistent internal body temperature
What are homeotherms?
List the three major reasons why all heterotrophs rely on autotrophs
What are 1) to produce all the food we will ever eat, 2) to produce all the oxygen we will ever breathe, and 3) to remove carbon gas from the atmosphere?
