19 cards·by oliviaryan

name the 5 kingdom model

Animals , Plants, Bacteria, Fungi, Protists (single celled Eukaryotes)

lists the 3 domain model....

Eukarya, Eubacteria, Archea (extremophiles)

Difference between sexual and asexual reproduction

asexual requires one parent and their offspring are genetically identical.. sexual-two parents, offspring have genetic variation

purpose of meiosis

creating gametes

most broad to scientific

KINGDOM, PHYLUM, CLASS, ORDER, FAMILY, GENUS, SPECIES

define classification :

identifing a species based on visible characteristics

what is binomial naming

the genus and species name. eg; homo sapiens

what is germination, describe two environmental triggers

when a seed starts to grow. water, even temperature

Why do spawning organisms release such a large number of gametes?

Some gametes will not fuse due to predators or environmental conditions

What is the difference between sequential and simultaneous hermaphrodites?

Sequential change genders during their life cycle, simultaneous possess both male and female reproductive organs at the same time.

Define parthenogenesis and name two other types of asexual reproduction.

Virgin birth (one parent self-fertilises). Binary fission, budding, runners, etc.

Describe three adaptations of terrestrial (land based) reproducers

Hard/water tight shells, internal fertilisation, internal development,

What is the difference between haploid and diploid cell?

Haploid have one set of chromosomes (one copy of every gene), diploid have two sets of chromosomes (two copies of each gene).

Which takes more energy, external or internal development?

Internal development, the parents needs to nourish the offspring for longer

Name three structures in an amniotic egg and their purpose.

Hard shell to stop it drying out, the yolk for energy, the white for water &nutrients

What is the difference between fertilisation, gestation and ovulation?

Fertilisation is when gametes meet, gestation is how long offspring develop internally and ovulation is when an ovary releases an egg.

corpus letum

lining of the uterus which protects growing offspring

3 ways of classifying...

DNA and genomes , feild guides, Dichotomous Key

what is the evidence required to classify?

the organism( dead or alive) , trace evidence (scats,fluid,hair) and other (trakcs,nets etc)
