1
Q

eukaryotic

A

nucleus
organelles
mitosis -cell division process
diploid

2
Q

prokaryotic

A

no nucleus
binary fission - cell division process
haploid

3
Q

eukaryotic cells contain DNA in what

3

A

nucleus
mitochondria
chloroplasts

4
Q

difference between animal and plant cells

A

cellulose
h2o preasure
one large vacuole– plant
animal – many vacuole

5
Q

chloroplasts

A

photocynthesis

6
Q

mitosis

A

identical duplication
1. interphase - replication genetic/cytoplasmic

2.prophase- chromatin thickens/ n. membrane
sipindle moves chromosomes around
3. metaphase- spindle moves to center of cell
chromosmes align along center
4. anaphase - chromosomes move apart and bend
once seperated -daughter chromosomes
5. telophase- spindle disinigrates
chromosomes — chomatin

7
Q

cytokinesis

A

splitting of the cell

8
Q

meosis

A

4 unique cells form

same phases — that happen twice

9
Q

genetic make up

A

chromosomes– genes– DNA–base pairs of nucleotides

10
Q

base pairs of nucleotides

A

adinine- thymine

cytocine-guanine

11
Q

DNA

A

deoxyribonucleic acid

12
Q

aleal

A

specific gene

determines what is expressed

13
Q

phenotype

A

physical expression

14
Q

genotype

A

gene inherited

15
Q

law of segregation

A

half and half from both parents

16
Q

law of independent assortment

A

random

17
Q

types of evolution

3

A

divergent- 1 species becomes 2

convergent - species that started different and evolved to become like each other (vultures)

paralell- over time species that become no more or less similar

18
Q

hierarchy of organism classification

A
species
genus 
family 
order 
class 
phylum 
kingdom 

king Phillip came over for good soup

19
Q

kingdoms

5

A
plantae
animalia 
protista 
monera
fungi
20

A
animalia 
cordata -----------phylum 
vertebrata ------ subphylum 
mamalia--------- class 
primate------ order
homidids--- family 
homo--- genis 
sapins -- species

micology

A

study of fungi

23
Q

types of fungi

A
mushrooms
yeasts
molds
rusts 
mildew
stinkhorns 
puffballs and  trufles
24
Q

fungi charaterized by

A

chitin cell walls

more similar to animals than plants

25
Q

food web link or level of nutrition

A

trophic levels

plants
(animals)
90% of energy is lost through heat in transfer through trophic levels

26
Q

biomagnification

A

increase in concentration of a substance inside of a food chain

27
Q

how many links do food chains consist of

A

6

aka ecopyrmids
