The three parts of the embryo are the
plumule, radicle, and cotyledons
The sprouting of a seed is also called ___.
germination
A fruit that forms from multiple flowers is a(n)
multiple fruit
The three main parts of the seed are the
endosperm, seed coat, and embryo
When something other than the fruit scatters the seeds, it is called ___ dispersal.
Agent
A cluster of flowers on one stem is called a(n)
inflorescence
When both male and female flowers are found on the same plant it is described as
monoecious
A plant with male and female flowers on separate plants is described as
dioecious
Fruits fall off the tree because of
the formation of the abscission layer
The fusing of the sperm and ovule is called
fertilization
The transfer of pollen from anther to stigma is called
pollination
Photosynthesis is an energy conversion that takes place inside the
chloroplast

mesophyll
What is the name of the green pigment that plays a key role in photosynthesis?
chlorophyll
The products of cellular respiration
CO2, H2O, ATP
Guard cells open and close the stomata by means of
turgor pressure
