Biology Unit 4 Quiz 4
mitosis
A zygote becomes a mature adult through the process of __________________________
juvenile
The first or earliest period of life in a young animal.
differentiation
A process changing cells or organisms from a generalized to a more specific or specialized condition. It often involves a reduction of the ability to reproduce or divide, and is usually not reversible.
diplontic
A type of life cycle in which meiosis produces gametes and the bulk of the life cycle is passed as a diploid. Adults are diploid.
external fertilization
A type of mating pattern in which eggs and sperm are released into the water after the mating partners come near one another. Fertilization occurs outside the body of the female.
haplontic
A life cycle in which meiosis occurs shortly after fertilization, and most of the life cycle is passed as a haploid.
internal fertilization
A mating pattern in which the male and female come close together and the male introduces the sperm into the body of the female where fertilization occurs.
complete metamorphosis
A type of metamorphosis in which the change from larva to adult occurs in one dramatic step. The larva and adult do not appear to be the same.
tadpole
A young frog or toad in the larval stage of development.
embryo
A zygote will develop into an ____________________ during the early stages.
False
The mechanisms controlling cell differentiation have been determined by microbiologists. True False
fertilized egg
The only portion of a haplontic life cycle that is diploid is the ________________________________________________________________
differentiation
The production of cells during mitosis into specialized function is called ________________________________________
adults producing gametes the growth of the offspring to adulthood fertilization
The term life cycle includes the entire process of: adults defending their young adults producing gametes providing a conducive environment the growth of the offspring to adulthood fertilization
metamorphosis
The transformation of a larva to an adult. It occurs only in animals having great differences in form between the larva and adult.
it is a highly complex genetic process it is completely governed by preexisting genetic information received by the zygote
Which statement(s) are true about metamorphosis: it is a highly complex genetic process it is completely governed by preexisting genetic information received by the zygote it is a form of accelerated evolution
False
Differentiation of cells changes the nucleic information. True False
aquatic
Something which lives in or pertains to water. An aquatic organism lives in water.
adult
Refers to grown or mature animals or plants.
True
The larva of a frog is a tadpole. True False
complete
A great change occurring in one step from the juvenile stage to the adult stage is called _____________________ metamorphosis.
organ
A group of tissues with a specific function in a part of the body.
tissue
A group or mass of cells having a common function.
isogamous fertilization
A haplontic cycle animal initially reproduces by: mitosis isogamous fertilization meiosis binary fission
incomplete metamorphosis
A kind of metamorphosis in which the change from larva to adult comes in several steps or stages. The change is not as dramatic as that of complete metamorphosis.
embryo
An early stage in the development of an animal or plant.
pupa
An insect is called a _____________ during the period of inactivity associated with complete metamorphosis.
mitosis
By what mechanism does a diplontic animal grow after fertilization? mitosis binary fission isogamous fertilization meiosis
initially by meiosis, then by mitosis
By what reproductive mechanism does a haplontic animal grow? initially by meiosis, then by mitosis completely by mitosis initially mitosis, then meiosis completely by meiosis
oogamous
Diplontic animals usually produce both eggs or sperm which are _____________________________
external
The kind of fertilization found in the majority of aquatic animals is ___________________ fertilization.
producing gametes
For an animal living a diplontic cycle, meiosis is limited to: producing growth producing gametes fertilization development of the zygote
larva adult
Incomplete metamorphosis is a change from ________________ to __________________ that takes place in a series of steps.
True
Mammals do not undergo metamorphosis. True False
True
Some cells of the body like neurons and brain cells do not reproduce themselves. True False
terrestrial
Something which occurs on the land or refers to the land.
tissues
Specialized cells which perform a particular function form _____________________
haplontic
The basic kind of life cycle found in the simplest animals is __________________________
pupa
The developmental stage between larva and adult in insects undergoing complete metamorphosis. It is usually a resistant stage with a thick layer of material protecting the insect from drying out or being harmed by outside influences or forces of various kinds.
life cycle
The idea that organisms reproduce from adult, to gametes, and back to adult again in a cycle or cyclical pattern.
larva
The juvenile stage or phase of life of an organism which undergoes metamorphosis.
