This is a baby plant inside a protective coat.
seed
This process uses sunlight to make food.
photosynthesis
A plant growing toward light shows this.
phototropism
This is the transfer of pollen.
pollination
This is the male flower part.
stamen
This is a growth response toward or away from a stimulus.
tropism
This process releases energy from sugar.
cellular respiration
Roots growing downward show this.
gravitropism
After fertilization, an ovule becomes this.
seed
This is the female flower part.
pistil
This is a chemical that controls plant growth.
plant hormone
These two processes are opposites of each other.
photosynthesis and cellular respiration
A vine wrapping around a pole shows this.
thigmotropism
This type of reproduction uses only one parent.
asexual reproduction
This part of the flower makes pollen.
stamen
This is something in the environment that causes a reaction.
stimulus
Photosynthesis produces these two things.
oxygen and sugar (glucose)
This is a response to changes in daylight length.
photoperiodism
Mosses and ferns reproduce using these.
spores
This structure contains the female cells.
ovule
This is the reproductive cell used by mosses and ferns.
spore
Plants need this energy source to perform photosynthesis.
sunlight
This hormone helps plants grow toward light.
auxin
This is one way seeds can be spread.
wind, water, or animals
After fertilization, this part turns into fruit.
