DESCRIPTION
Investigates plant reproduction: concepts, terminology, types of reproduction, pollination, and
seed development and germination. Includes questions, review, and a quiz.
ACADEMIC STANDARDS
Subject Area: Science: Life Sciences
• Standard: Understands the principles of heredity and related concepts
ƒ
Benchmark: Understands asexual and sexual reproduction (e.g., in asexual
reproduction, all the genes come from a single parent; in sexual reproduction, an egg
and sperm unite and half of the genes come from each parent, so the offspring is never
identical to either of its parents; sexual reproduction allows for greater genetic diversity;
asexual reproduction limits the spread of disadvantageous characteristics through a
species)
• Standard: Understands the structure and function of cells and organisms
ƒ
Benchmark: Knows how an organism’s ability to regulate its internal environment
enables the organism to obtain and use resources, grow, reproduce, and maintain stable
internal conditions while living in a constantly changing external environment

To describe the difference between “sexual” and “asexual” reproduction.
To generally define the term alternation of generations.
To identify the sporophyte and gametophyte phases in mosses and ferns.

To identify reproductive structures of gymnosperms, including pollen, male cones, female
cones, eggs and naked seeds.
To describe the process of fertilization in gymnosperms.
To identify reproductive structures of angiosperms, including pollen, stamen, anther,
filament, pistil, stigma, style, ovary, egg, and seed.
To describe the process of pollination and fertilization in angiosperms.
To define the terms seed dispersal and germination.

BEFORE SHOWING
1. Define reproduction for the class.
2. Divide the students into groups. Ask students to name different ways in which reproduction
may occur in plants. Allow each group about five minutes to construct a list and then
discuss the examples as a class. Have one representative from each group write their list on
the board. Next, ask students to list the benefits of some of these repro-ductive processes
in plants. Discuss these examples as a class and add the list to that already on the board.
Leave the lists on the board during the video. After viewing the program, ask students to
add to the list examples they may have learned from the video.
DURING SHOWING
Applications and Activities
1. Complete the “You Decide” questions as they are presented during the course of the
program. (See INSTRUCTIONAL GRAPHICS.)
2. Answer the ten video quiz questions at the end of the video. (See INSTRUCTIONAL
GRAPHICS.)

What are stamens?
What is a filament?
What is an anther?
What is a pistil?
What is a stigma?
What is a style?
From where do bees obtain nectar?
From where does honey come?
What is pollination?
How is pollen transported from the male part to the female part of the flower?
What happens when an egg is fertilized?
Give examples of how seeds can be dispersed.
Applications and Activities
Observe the structure of pollen grains of different types of flowers under a microscope.
First, place a drop of water on the center of each of the microscope slides. Using a toothpick,
carefully take some pollen from the anther of each flower and place the cover slip over the
pollen grains and place the microscope slide on the stage of the micro-scope. Second, observe
the pollen samples from each flower separately. Third, describe differences in the structure of
the pollen grains from each type of flower. Fourth, sketch each type of pollen grain. Lastly,
describe the role that pollen plays in the reproductive process of angiosperms.
