response

An action that is prompted by a stimulus

Plant tissue that transports water absorbed in roots throughout the

phloem

Plant tissue that transports glucose produced by the leaves throughout

guard cells

Cells surrounding the stoma that regulate the size of the stoma

A tiny pore in the epidermis of a leaf used for gas exchange

pollination

The transfer of pollen from the anther to the stigma within a flower

pollen

Small particles containing a plant’s sperm cells

sexual reproduction

Reproduction that involves the exchange of genetic material between two organisms

stamen

The male reproductive structure of a flowering plant; consists of the anther

pistil

The female reproductive structure of a flowering plant; consists of the stigma, style,

filament

The slender stalk-like portion of the male reproductive structure of a flowering plant;

anther

The portion of the male reproductive structure of a flowering plant that contains

stigma

The sticky tip of the female reproductive structure of a flowering plant; it is sticky in order to capture

pollen for the purpose of pollination

The slender stalk-like portion of the female reproductive structure of a flowering plant;

The enlarged portion at the base of the reproductive structure of the flowering plant that contains ovules (the female gamete); after fertilization it will become the fruit

flower

The reproductive organ in angiosperms that develop into fruit and seeds

carpel

The seed-producing reproductive organ in flowering plants that contains the ovule,

Leaves surrounding the reproductive structures of flowering plants, often specialized to attract

Protective structure that surrounds a flower bud, and supports petals after a flower

Structure within the ovary of a plant containing the female reproductive cells; develops into the seed after fertilization

The specialized part of a plant that grows down into the soil to anchor the plant and absorb

nutrients

The specialized part of a plant that grows in the opposite direction of the roots and supports the

flower, leaves, or fruit of the plant

leaf (leaves)

The specialized part of a plant that is mainly used for gas exchange; comes in various forms and often

the primary form of adaptation in plants

Usually unicellular body formed as a result of either sexual or asexual reproduction; has the ability to give rise to a new organism and the

advantage of being able to wait until ideal conditions arise

cell wall

Outer layer of a plant cell used for protection and support

chloroplast

Organelle where sugars are produced during photosynthesis; found in autotrophic cells

vascular tissue

A set of ducts and vessels which allows water, minerals, and food to move

The result of a fertilized plant ovule; can be cultivated to produce a new plant

taproot

A primary root that grows down with small lateral roots

tissue

A group of cells with a similar structure and function

angiosperm

A class of plants that produce flowers

gymnosperm

A class of plants that produce naked seeds found in cones instead of ovaries

monocot

A flowering plant whose seed has one cotyledon

A flowering plant whose seed has two cotyledons

auxins

A plant hormone that makes roots form and buds grow

germination

The process of sprouting and growing

gravitropism

A plant’s ability to move toward the earth (roots) or away from the earth (stems)

phototropism

A plant’s ability to move toward the sunlight

thigmotropism

A plant’s ability to move when it comes in contact with another object

haploid

A cell that contains a single set of chromosome; n

diploid

A cell that contains pairs of all of the homologous chromosomes; 2n

gametophyte

The haploid stage of a plant that produces gametes by mitosis

sporophyte

The diploid stage of a plant that produces spores by meiosis

transpiration

The process of a plant absorbing water through the roots and then releasing water

turgor pressure

The pressure inside a cell that is exerted against the cell wall by
