|
Interphase
|
cells preparing for mitosis
|
|
|
G1
|
Dublicating organelles
|
|
|
S1
|
DNA replication occurs
|
|
|
G2
|
Final preparation for cell
|
|
|
Prophase
|
DNA condenses, spindle fibers attach, nuclear envelope disappears, kintechores form centromere
|
|
|
Metaphase
|
sister chromatids align at metaphase plate
|
|
|
Anaphase
|
chromosomes migrate to opposite poles of the cell
|
|
|
Telophase
|
nuclear envelope forms, spindle fibers deattach, chromosomes decondense
|
|
|
Cytokensis
|
division of cytoplasm, occurs during and after telophase
|
|
|
Activation energy
|
energy require to start a chemical reaction
|
|
|
enzyme
|
biological catalyst, accelerates chemical reactions, made up of proteins, can be reversible, can be reused if not denatured, speeds up chemical reactions, 3D shape
|
|
|
Light dependent reactions
|
occur in the thylakoid membranes, chlorophyll captures light energy
|
|
|
Light independent reactions
|
occur in the stroma, light energy and co2 covert into carbohydrates
|
|
|
Carbon Fixation
|
conversion of co2 into organic compounds
|
|
|
grana
|
Stacks of thylakoids
|
|
|
thylakoids
|
independent stacks made up of pigments that are made up for absorbing light
|
|
|
Chromosomes
|
thread like structure made of DNA and proteins
|
|
|
Gene
|
sequence of DNA responsible for a trait
|
|
|
Meosis
|
formation of gamates
|
|
|
Prophase 2
|
spindle fibers reform
|
|
|
Metaphase 2
|
sister chromatids align at metaphase plate
|
|
|
Anaphase 2
|
sister chromatids seperate
|
|
|
Telophase 2
|
cells fully divide
|
|
|
Fertilazation
|
2 sex cells of an organism fuse
|
|
|
Genetics
|
study of pattern of inheritance
|
|
|
Heridity
|
traits passed down from parents to offspring
|
|
|
Law of segreagation
|
trait from two alleles that have separated and recombined randomly
|
|
|
Crossing over
|
when segments of DNA are exchanged b/w non sister chromatids
|
|
|
Law of independent assortment
|
during meiosis, alleles of a gene for one trait separate independently from the alleles for traits on other chromosomes
|
|
|
Codomiance
|
both homozygous phenotypes expressed completely as heterzygous
|
|
|
incomplete domiance
|
heterzygous phenotypes is a combination of two homozygous phenotypes
|
|
|
what does photosynthesis convert
|
light energy into chemical energy
|
|
|
What carries out photosynthesis
|
chloroplast
|
