CELLS
The powerhouse of the cell
What is the Mitochondria
This molecule contains hereditary information in living organisms
what is DNA
this prosses allows plants to covert sunlight into chemical energy
what is photosynthesis??
Change over mutlipule generations to inherited chacteristics
Evolution
after a restraint on a population's environment of necessary sources only a certain few with a selective few traits survived
natural selection
It controls what enters and leaves the cell
What is the cell membrane
they are different forms of the same gene that my produce different traits
what is an Allele
this green pigment absorbs light energy for photosynthisis
what is chlorophyll
the pattern of natural selection favors individuals with intermediate values of a trait has an advantage over other individuals in a population.
what is stabilizing selection???
this term describes the variety of living organisms in an ecosystem, biome, or earth as an whole
what is biodiversity
this organelle contains digestive enzymes that break down waste materials
what is lysosome
this prosses copies DNA before a cell divides
What is DNA replication
this stage of photosynthesis uses carbon dioxide to produce sugars
what is the Calvin cycle???
these structures are similar in different species because they were inherited from a common ancestor
what is a homologous structure???
this biome is known for extremely high biodiversity, heavy rain fall and layered plant growth including the canopy and understory
what is a tropical rainforest???
this selective permeable structure controls movment into and out of the cell.
what is the cell membrane
this type of cell division produces cells with half the normal numbers of chromosomes.
what is meiosis
these small openings on leaves regulate gas exchange and water loss
what is a stomata
A Population of organisms experience a drastic reduction in size after a natural disaster causing genetic variation in future generation
what is the bottleneck effect???
this term describes a species whose losss would cause major changes to an ecoysystem
what is a key stone species
this organelle modifies, sorts and packages proteins for transport
what does the Golgi apparatus do???
this prosses occurs when segments of homologous chromosomes exchange genetic material during meiosis.
what is crossing over
this vascular tissue transports water and dissolved minerals for the roots to the rest of the plant
what is phloem
Bacteria acquire resistance genes from other bacteria through the direct transfer of plasmid DNA using physical connections between cells
what is conjugstion
an artificial grouping because its organisms are classified mainly by not anything else
what are protists
