Question 7

perianth

Accepted Answer

the sepals and the petals on a flower.

Question 8

petal

Accepted Answer

leaflike structures located just inside the sepals that are often very colorful and often function to attract pollinators, such as insects and birds.

Question 9

photoperiodism

Accepted Answer

a plant's response to light duration.

Question 10

photoreceptor

Accepted Answer

light- sensitive pigments.

Question 11

phytochrome

Accepted Answer

Question 12

pistil

Accepted Answer

the female part of a flower composed of the stigma, the style, and the ovary.

Question 13

plantlet

Accepted Answer

shoots that develop from buds that form on explants in tissue culture propagation.

Question 14

pollen grain

Accepted Answer

immature male gametophytes.

Question 15

pollination

Accepted Answer

the process in which a pollen grain is blown and adheres to the sticky surface of a female structure.

Question 16

receptacle

Accepted Answer

the portion of the pedicel that holds the flower parts.

Question 17

rootstock

Accepted Answer

the lower portion of a plant that includes the root system; also known as the understock.

Question 18

scion

Accepted Answer

the portion of a graft that is to become the stem.

Question 19

seed

Accepted Answer

a reproductive body formed from an ovule after fertilization and composed of an embryo and nutritive tissue.

Question 20

seed coat

Accepted Answer

a structure that consists of one or more protective layers that encase the seed and protect the contents.

Question 21

self-pollination

Accepted Answer

pollination of a flower with pollen from the same plant.

Question 22

sepal

Accepted Answer

green leaflike structures on the exterior of a flower.

Question 23

separation

Accepted Answer

a method of asexual reproduction in which vegetative plant structures are removed intact from the parent plant and planted.

Question 24

sexual reproduction

Accepted Answer

the fusion of sex cells (sperm and egg), with each cell contributing genetic material and the resulting offspring being genetically different from the parent plants.

Question 25

short-day plant

Accepted Answer

plants that flower naturally in late summer and in fall, when the day length gets shorter.

Question 26

sporophyte

Accepted Answer

a multicellular diploid stage of a plant's life cycle that produces spores.

Question 27

stamen

Accepted Answer

the male reproductive part of the flower, consisting of a filament and an anther.

Question 28

stem cutting

Accepted Answer

a method of asexual reproduction in which the stem and leaf portions of a plant, 2 to 5 inches in length, are taken in the morning when the tissues are turgid, or full of water.

Question 29

stigma

Accepted Answer

a structure found at the end of the pistil that has a sticky surface on which pollen lands.

Question 30

style

Accepted Answer

the neck of the pistil.

Question 31

tepal

Accepted Answer

the name given to parts of the perianth when a clear distinction between petals and sepals cannot be made.

Question 32

thermoperiodism

Accepted Answer

a plant response to temperature.

Question 33

tissue culture

Accepted Answer

a very technical method of asexual propagation that involves the culture, or growing, of small pieces of plant tissue on an artificial medium under sterile conditions.

Question 34

totipotency

Accepted Answer

the ability of cells to provide information for the development of an entire plant.

Question 35

vernalization

Accepted Answer

a physiological process in some plants in which they must be exposed to freezing or near-freezing temperatures for a number of weeks to satisfy a cold requirement in older to develop or grow further.
