Parts of a Plant & Flower Notes
1. Label the flower, fruit, leaf, root, seed, and stem then write down what each part does for the plant.
The flower ___reproduces by making
seeds________
The fruit __protects the seed__
___________________________________
The leaf ____does photosynthesis to make
food____________________________
The root __collects water and anchors the
plant into the ground________
The seed ___makes a new (baby) plant___
___________________________________
The stem ___carries food, water, and
minerals where needed____
2. Label the anther, egg, filament, ovary, petal, pistil, pollen, sepal, stamen, stigma, and style then
write down what each part below does for the plant.
pistil
stamen
(female part)
(male part)
The ovary __makes the egg cells____
___________________________________
The petal _is the colorful part of the flower
that attracts insects and other pollinators
stigma
style
The pistil __is the female part of the flower
pollen
anther
filament
that does reproduction___
The pollen __is the sperm, it fertilizes
the egg cell__
The sepal __is the seed leaf and protects
the bud___
petal
ovary
The stamen _is the male part of the flower,
it makes the pollen or sperm_
sepal
egg
3. Pollination is _when pollen from the anther of the stamen reaches the stigma of the pistil___
4. Fertilization is __when the sperm (pollen) reaches the egg (ovule) in the ovary and combines___
Plant Processes
5. __Photosynthesis____ is the process plants do to make their own food.
6. The _chloroplast__ in the plant cells have chlorophyll that uses carbon dioxide and water with
___sunlight____ to make glucose (sugar) and oxygen.
light energy
6CO2 + 6H2O ------------------------------------------ C6H12O6 + 6O2
7. __Cellular respiration___ is the process where plants use oxygen to release the stored energy in the
chemical bonds of __glucose__. Carbon dioxide and water are waste products. This process is done
inside the __mitochondria___.
C6H12O6 + 6O2 ------------------------------------------ 6CO2 + 6H2O + ATP
8. Plants do cellular respiration when they need energy and can't do __photosynthesis___.
This happens at night, during a drought, when the plant is dormant.
9. __Transpiration___ is when the sun evaporates water from plant leaves. Deciduous plants drop their
leaves in the fall so they do not lose water through transpiration over the winter when there is not
enough direct sunlight to do ___photosynthesis___.
10. __Dormancy__ is when plants stop growth because they do not have what is needed for
photosynthesis. This can be a plant that has dropped its leaves for the winter or grass that has turned
brown when there is not enough water to do photosynthesis during the summer.
11. Phototropism is when plants change the direction they are growing to get more __light_.
12. Gravitropism is when plants change the __direction__ they are growing in response to gravity. The
stems grow upward and the _roots__ grow downward.
.
What part of this plant is showing phototropism? Why?
The stem is growing towards the light even though the pot
has been knocked over. The plant does this to get light to do
photosynthesis.
What part of this plant is showing gravitropism? Why?
Mainly the roots are showing gravitropism. They are
growing down even though the pot has been knocked over.
They do this so that they can stay in the ground and get the
water and nutrients in the soil.
