Cross pollination or self pollination?
Let’s review:
1. Identify the male part of the flower. Stamen
2. Identify the female part of the flower. Pistil
3. Where is pollen produced? Anther
4. Where are eggs produced? Ovules
5. Identify the structure pollen stick to. Stigma
6. Identify the process in which pollen sticks to the
stigma. Pollination
7. How are pollinators attracted to flowers? Petals
8. How else can a flower be pollinated? Wind
9. Identify the structure that forms in the style to
bring pollen to the eggs. Pollen tube
10. What happens to the ovules and ovary once the eggs
are fertilized? Ovary turns into the fruit.
Ovules turns into the seeds.
The part of the pistil which
contains the pollen tube is the

The transfer of pollen between
the anther and the stigma in any
flowering plant or plants is
called
(1)fertilization
(2)pollination
(3)photosynthesis
(4)transpiration
The sex cells in a flowering
plant are located in the
(1) sepals and petals
(2) stigma and nectar
(3) fruit and seed
(4) stamens and pistil
In order to reach an ovule, a
___________ grows
through the style and into
the ovary.

(2) fruit
(3) pollen tube
(4) seed
The egg cell of a flowering
plant develops in the
(1) pollen grain
(2) ovule
(3) stigma
(4) fruit
The sperm of flowering plants
is contained in the
(1) ovule
(2) pollen grains
(3) style
(4) stigma
The entire female reproductive
organ in flowering plants is
called the
(1) pistil
(2) stamen
(3) stigma
