STUDY GUIDE for pages 156-161
1. An _________________________________ is a plant that produces seeds enclosed in a fruit.
2. The ______________________ is a protective vessel where seeds develop.
3. Two characteristics of all angiosperms are:
1) __________________________________________________________________________
2) ___________________________________________________________________________
4. ________________________ are the colorful structures of the flower that you see when the flower
opens and they attract insects and other animals.
5. The leaf-like structures that protect the bud or developing flower are called __________________.
6. ___________________________ are the male reproductive part of the flower.
7. Stamens consist of a thin stalk called the _______________________________ and a knob on
top of the filament, called the ___________________________ that produces pollen.
8. The female reproductive part of the flower called the _____________________ is located in the
center of the flower. Some flowers have two or more, others only have one.
9. The sticky tip of the pistil is called the _________________________ and pollen sticks to it.
10. A hollow tube for pollen to travel down, that connects the stigma to the ovary, is called the
_____________________.
11. The _______________________ is a hollow oval structure that contains 1 or more ovules, and is
where the seeds will develop.
12. _______________________________ is when pollen falls on the sticky stigma, by wind, water, or
animals.
13. When the male sex cell in a grain of pollen unites with an ovule (the female sex cell) in the ovary
and forms a zygote, ___________________________________ has taken place.
14. Inside the seed, the zygote develops into the _________________________ which will become the
new plant.
15. The ripened ovary which contains one or more seeds is called the ___________________.
Examples are apples, cherries, tomatoes, squash, and green peppers.
16. Two types of Angiosperms are Monocots and Dicots. Look on page 160 for their characteristics
and list them here:
