Intro to Biology
The idea that life could arise from nonliving matter
Spontaneous Generation
What are the reactants of photosynthesis?
Carbon dioxide and water, aided by energy from the sun (last part not necessary)
Center of production of energy
Mitochondria
Fats, oils, and waxes for long term energy storage
Each step in the food web or food chain
Trophic level
Combination of chemical reactions through which an organism builds up or breaks down materials as it carries out its life processes is called _____
Metabolism
The products of photosynthesis
oxygen and glucose
An organelle containing digestive enzymes that break down waste
Lysosome
What are carbohydrates and what do they do?
Sugars and starches that supply energy for the cell.
The total amount of living tissue within a certain trophic level
Biomass
The process by which organisms keep internal conditions fairly constant in order to survive is
Homeostasis
The process whereby plants capture energy and make complex molecules
Photosynthesis
A small, round body of protein in a cell nucleus that assembles ribosomes
Nucleolus
What are proteins and what do they do?
Amino acids for building and repairing tissues
The combined portions of the planet in which all life exists
Biosphere
Scientist that proved that maggots only appear on meat when flies have contact with the meat, helping to disprove spontaneous generation
Francesco Redi
2 activators that must be present in order for photosynthesis to take place in green plants
(not the reactants)
chlorophyll and sunlight
Stack of membranes in the cell that modifies, sorts, and packages proteins from the endoplasmic reticulum for storage
golgi body/ apparatus
What are nucleic acids and what do they do?
DNA, RNA for storing and transmitting genetic information
The process by which bacteria convert nitrates into nitrogen gas and then release nitrogen into the atmosphere.
Denitrification
Scientist who used a curved flask to prove that all living things come from other living things, finally disproving spontaneous generation once and for all.
Louis Pasteur
The 2 stages of photosynthesis
Light Dependent
Light Independent/ Calvin Cycle
Responsible for folding proteins, producing lipids, and aiding in the transport of macromolecules inside the cell
Endoplasmic reticulum
What is a catalyst?
Accelerates chemical reactions
The process by which bacteria convert nitrogen gas into ammonia
Nitrogen fixation
