Section 22–5 Angiosperms—Flowering Plants
(pages 569–572)
TEKS FOCUS: 3D Careers; 13A Structural and physiological adaptations; 13B Methods of
reproduction, growth, and development; TEKS SUPPORT: 8A Classify organisms
This section identifies the characteristics of angiosperms. It also explains what
monocots and dicots are and describes the three categories of plant life spans.
Flowers and Fruits
(page 569)
1. Angiosperms are members of the phylum
Anthopyta
.
2. Angiosperms have unique reproductive organs known as
flowers
3. During which geologic period did flowering plants first appear?
They first appeared
.
during the Cretaceous Period.
ovary
4. In flowering plants, the seed is encased in a(an)
.
5. What is a fruit? It is a wall of tissue surrounding the seed.
6. Why is using fruit to attract animals one of the reasons for the success of flowering
plants? An animal eats the fruit, and by the time the seeds leave its digestive system the animal
may have traveled many miles. By using fruit to attract animals, flowering plants increase the ranges
they inhabit.
Diversity of Angiosperms
(pages 570–572)
7. The seed leaves of plant embryos are called
cotyledons
.

10. Circle the letter of each plant feature that is characteristic of dicots.
a. Parallel leaf veins
b. Floral parts in multiples of 4 or 5
c. Roots include a taproot
d. Vascular bundles scattered throughout stem
11. Woody plants are made primarily of what kind of cells? They are made primarily of cells
with thick cell walls that support the plant body.
12. What characteristics do the stems of herbaceous plants have? Their plant stems are
smooth and nonwoody.
13. Complete the table about plant life spans.
PLANT LIFE SPANS
Category
Definition
Examples
Annuals
Angiosperms that complete a life cycle
within one growing season
Marigolds, petunias, pansies, wheat, corn,
cucumbers
Biennials
Angiosperms that complete a life cycle
in two years
Parsley, celery, foxgloves
Perennials
Angiosperms that live more than two
years
Peonies, asparagus, grasses, palm trees,
sagebrush, oak trees, honeysuckle
short stems, and sometimes leaves.
15. What happens to biennials once their flowers produce seeds? They die.
16. Is the following sentence true or false? Most perennials have herbaceous stems.
false
