Cellular Respiration Equation
Cellular Respiration Definition
The process by which molecules are converted into useable energy in cells
The process that uses light energy to convert CO2 from the air, water from the soil to make simple sugars(Carbs) and Oxygen
How much energy is passed to another organism in a food chain?
Where do most organisms get their energy?
The sun :D
1)can make energy through chemical reactions- chemosynthesis-that is later used by other organisms.
series of steps in which organisms transfer energy by eating and being eaten. (more specific than a food web, found within food webs)
network of feeding interactions
Essential to Earth because they release nutrients that primary producers can use again by eating dead animals or waste products- called decomposition
the different kinds of organisms in a specific ecosystem or on the whole planet
A substance that can be burned for heat energy, such as coal, oil,or natural gas formed from decayed remains of dead plants and animals
How to find population density?
# of Organisms/Area
the addition of matter, energy, or information to a system
the process of converting nitrogen gas into ammonia that plants absorb and use
the maximum number of a certain that a particular environment can support
an ecological environmental area that is inhabited by a particular species, a natural environment a species lives in.
The position of a species or population in its ecosystem. How and where an organism makes a living.
determines the carrying capacity of an environment for a species. ( determines the number of species in an environment)
When populations become overcrowded, individuals compete for food, water, space, sunlight, and other essentials.
species that have become able to survive and reproduce outside the habitats they originally came from.
a natural unit consisting of all plants, animals, microorganisms, in an area functioning together.
any change in the structure or functioning of an organisms that is favored by natural selection and make the organism better suited for environment.
a series of gradual changes or rapid changes.
Where do mutations occur?
in DNA or sperm/egg (caused by environmental factors and copying mistakes)
the process by which heritable traits that are favored by environmental conditions become more common in later generations. Over time this can create a new species.
Mutations are changes in...
What are the nucleotide names?
Adenine (A), Cytosine ( C ), Guanine (G), Thymine (T)
Pairs: A+C(purines) and C+T(pyrimidines)
1)Animals only do....
2) Plants do...
2) Photosynthesis AND Cellular Respiration
What do cellular respiration and burning fossil fuels have in common?
1)both processes involve combustion of carbon containing compounds to transform chemical energy to a different for of energy.
2) both release carbon into the atmosphere
1)the organelle of a cell that carries on cellular respiration, release energy from food molecules, and store in it ATP.
2)use sugar and other organic compounds to produce energy(ATP). POWER HOUSE OF CELL
ONLY IN PLANT CELLS-produce sugar
convert mRNA message from DNA into protein
Houses DNA that are wrapped around proteins forming long, coiled strands called chromosomes. Also mRNA and tRNA are here.
regulates what can enter and leave the cell.
Cell Membrane Structure
composed of PHOSPHOLIPID BILAYER that is selectively permeable. Small, uncharged particles may pass through, but other molecules must pass through protein channels.
large molecules that live inside the nucleus that carry genetic information
The production of two identical nuclei in one cell followed by cell division and the production of two cells with the same genetic makeup as the original cell.
A process of a cell division that produces reproductive cells known as gametes (eggs/sperm). Each gamete contains only one set of the unpaired chromosomes and half as much genetic info. as the original cell.
