1. ____________________ This is the entire male reproductive structure of an angiosperm.
2. ____________________ What type of vascular tissue transports nutrients?
3. ____________________ This structure protects the active growing cells of a root.
4. ____________________ What structures increase surface area for the roots so that they can
absorb more minerals, nutrients, and water?
5. ____________________ This part of a flower is very sticky so that pollen can become
attached in order for reproduction to occur.
6. ____________________This is the waxy coving of a plant that does not allow CO2 or O2 to
enter/leave the plant
7. ____________________ This is the vascular tissue that transports water and minerals.
8. ____________________ These cells border the opening of a plant’s cuticle and are
responsible for opening and closing these holes.
9. ____________________ This is the enlarged base of the angiosperm’s female reproductive
structure.
10. ____________________ This type of tissue does not transport any materials; it is used for
support and structure by the plant.
11. ____________________ What part of an angiosperm’s male reproductive parts contains
the flower’s pollen?
12. ____________________ These are the modified leaves of an angiosperm that protect
young flowers.
13. ____________________ What is produced when the egg and sperm from a flower
germinate?
14. ____________________ What is the entire female reproductive structure of an
angiosperm called?
15. ____________________ What are the holes or pores in a plant’s cuticle called?
16. ____________________ This part of a flower is brightly colored to attract insects.
17. ____________________ This is the structure in which the sperm from the pollen travels
down in order to meet up with a flower’s egg.

Fill in the blanks with the appropriate terms related to population dispersion.
__________________ dispersion consists of organisms that are pollinated by the wind
and can grow where ever they land because there is an abundance of ___________________;
as a result, competition between organisms is very rare. An example of this type of dispersion
would be ________________________.
Organisms that grow at a precise distance from another organism of the same species
display __________________ dispersion. There is a consistent distance between each
organism of the population An example of this type of dispersion would be
__________________.
The most common type of dispersion in nature is known as ________________________
dispersion. Organisms grow near essential resources. _____________________, for example,
grow best in moist soil next to bodies of water.
