6 charactics of a living thing
-made of cells -grows
-reproduce
-use eneregy
-contain genetic maderial
-respond to enviornmant
binomal nomenclature
1st word is the Genus and 2nd is the species
cell membrane
regulates what can go in and out of cell
cell wall
in plants, and fungi
chloroplasts
only in plant cells
cytoplasm
jelly like substance inside the cell
cell theory
- all organisms made of 1 or more cells
2. all cells come from cells
3. cell is basic unit of life
prokaryote
cell has no nucleus
eukaryote
cell has a nucleus
virus
non-living b/c doesnt grow and cant reproduce on its own
3 things organisms need to survive
1.water
2.place to live
3. food or energy source
caral linnaeus
developed binomal nomenclature
how are cells, tissues, and organs related & organised?
cells group with tissues
tissues group with organs
order of classification system we use today
kingdom, phylum, class, order, family, genus, species
active transport
energy is required to move items in and out of cell
passive transport
energy isnt required to move items in and out of cell
diffusion
molecules move from an area of high concentration to low concentration
osmosis
diffusion of water through a cell membrane
endocytosis
how a cell takes in large molecules
exocytosis
vesicles fuse with cell membrane
inorganic compound
made from elements other than carbon
organic compound
contains carbon and hydrogen
mixture
combonation of substances where the individual substances retain their own properties
sexual reproduction
2 sex cells form together
diploid
double
haploid
half
DNA
deoeyribose nucleic acid
fertilization
joinging of egg and sperm
meiosis
produces haploid sex cells
mutation
occurs when DNA isnt copied correctly
RNA
ribonucleic acid
mitosis
nucleus divides
egg
formed in female reproduction organs
sperm
formed in male reproductive organs
zugote
cell formed duringfertilization
gene
carry most of your charactics
chromosome
carry genes
interphase
most of the life of a cell is spent here
how many pairs of chromosomes do humans have? diploid #? haploid #?
23 pairs
46
23
how many times does the nucleus divide during meiosis?
2 times
proteins are composed of _____________
DNA
what are the functions of the 3 types of RNA
messengerRNA transferRNA
ribosomalRNA
End product of meiosis
4 cells half # chromo in each cell than at begening
end product of mitosis
2 cells witrh same # of chromo as orinal cell
allele
alterenate for that a gene mighth have
dominant
covers over the other trait
genetic engennering
changes arrangement of genes
genetics
study of how traits are inherited
genotype
genetic makeup of an organism
hereditary
passing of trait from parent to offspring
heterozygous
Ll or Gg or Rr
homozygous
GG or gg or RR or rr
hybrid
offspring that was given diff genetic material
incomplete dominance
production of a phenotype
phenotype
outward physical apperance (resulty of genotype)
poloygentic inheritence
occurs when a group of genes act together to produce a specific trait
punnet square
tool used to predict probability of an offspring
recessive
trait that is dominated by another trait
sex-linked gene
allele inherited on a sex chromosome
name things that can be inherited
eye color, skin color, hair color, nose shape, height
