biology

The stock is the portion of a plant with the root system used in

grafting.

A haplontic animal re productively grows initially by

meiosis, then by mitosis. A diplomatic animal grows by mitosis.

Normally, a homologous pair of chromosomes is required to determine the

outward expression of a trait.

A rhizome is a horizontal stem at or just beneath the surface of the ground which can give rise

roots or stems.

The only haploid cells in an organism are the

gametes.

Cells or organisms having pairs of

homologous chromosomes are diploid.

An architectonic is the egg-producing organ in

lower plants.

When an animal or plant of many cells breaks up into two or more parts, and when these parts survive to produce a

new organism, reproduction occurs by what is known as regeneration.

Approximately 1 year is required in the gymnosperm between

pollination and fertilization. Mitosis is a form an asexual reproduction.

The gametophyte generation of the fern plant produces

reproductive organs which produce a zygote.

All chromosomes in a diploid cell come in matched pairs except the

sex chromosomes.

Cancer is a common disease characterized by

uncontrolled mitosis.

Plants that produce their gametes in flowers are called

angiosperms.

Offspring which arise as a contiguous outgrowth of the parent is known as

budding.

The mismatch of a NDA base pair during duplication can results in a

change or a mutation.

Reproduction by mitosis duplicates

chromosomes, genes, and DNA.
