Structure of Flowers
This part of a flower covers and protects the rest of the flower during development
sepal
Reproductive cells, such as egg cells and sperm cells
gametes
Consists of an outer fleshy layer and an inner papery core
pome
The period of inactivity that occurs before germination
dormancy
Consists of a seed enclosed in a hard, relatively thick shell
nut
This part of the flower produces pollen
anther
After pollination takes place, the formation of this is the first step in fertilization
pollen tube
Entire fruit is fleshy and juicy throughout
berry
The part of the seed's embryo that develops into the new plant's root system
radicle
Produced by plants of the grass family
grain
A flower that lacks either sepals, petals, stamens, or pistils
incomplete flower
The type of reproduction in which sperm and egg cells unite
sexual reproduction
Consists of a pod enclosing several seeds
legume
The structures of a plant embryo that contain stored food to supply the energy needed for sprouting
cotyledons
This type of fruit has an outer fleshy layer and an inner woody layer
drupe
This part of the flower is made up of the stigma, style, and ovary
pistil
The tissue that surrounds and nourishes a developing plant embryo
endosperm
A type of seed dispersal in which an outside agent carries the seeds
agent dispersal
The first process of germination
the seed begins to absorb water
Type of pollination that occurs in the same flower
self-pollination
This is the chief factor to determine when a plant will flower
length of day and night
When there is a fully developed fruit on a plant, this is true of the ovary
it has ripened
This type of fruit grows from a single flower with several pistils
aggregate fruit
The part of a plant embryo that develops into stems and leaves
plumule
This produces xylem and phloem, which are in wood and bark
vascular cambium
