(20 cards)
is a form of intermediate in which one allele for a specific trait is not completely dominant over the other allele
incomplete dominance
both allele are expressed equally in the phenotype of the heterozygote.
codominance
a different form of gene that controls a certain trait.
allele
a dark staining, red-shape structure in the nucleus of a eukaryotic cell consisting of a continuous molecule of DNA wrapped in protein
chromesomes
are reproductive cells that reunite during the sexual reproduction.
gamete
is the external appearance of an organism that is determined by the individual’s genotype, or it’s the physical characteristics that you see in an organism like color, structure, height, etc.
phenotype
the genetic make-up of an organism, it means it is something that we cannot see but it is the bases for the physical appearance of the organism.
genotype
the method by which one can determine the possible genotype and phentype when two parents are crossed.nIt is a model used to establish the possibilities of the results of a genetic cross.
punnet square
it is where an animal, plant, or any kind of species are in one place
biodiversity
is a group of organisms of the same species living in a certain place.
population
the trapping of heat by gases in the earth’s atmosphere is called?
greenhouse effect
is an increase in the earth’s temperature from the rapid builup of carbon dioxide and other gases.
global warming
the extreme heat that the world is feeling or experiencing right now is due to the?
climate change
inside the plant cell that store the energy of sunlight.
chloroplasts
the thylakoid membranes of the chloroplast is a light absorbing pigment called _________________ which is responsible for giving its plant color greeen.
chlorophyll
is a process of food making done by plant and other autotrophic organisms.
photosynthesis
is the second set of biochemical reactions in photosynthesis and follows the light energy.
calvin cycle
happens in the presence of light. It occurs in the thylakoid membrane and converts light energy to chemical energy
light dependent reaction
is light dependent phase that takes place in the stroma and converts carbon dioxide (CO2) into sugar.
calvin cycle (dark reaction)
are found on the lower surface of the leaf that allows the entrance of carbon dioxide needed for photosynthesis.
