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.
