36. Introduction to Plant Reproduction
Reviewing Main Ideas 1
Introduction to Plant Reproduction
Plants reproduce sexually and asexually. Sexual reproduction involves the formation of sex cells and fertilization.
Asexual reproduction does not involve sex cells and produces plants genetically identical to the parent plant.

37. Introduction to Plant Reproduction
Reviewing Main Ideas 1
Introduction to Plant Reproduction
Plant life cycles include a gametophyte and a sporophyte stage. The gametophyte stage begins with meiosis. The sporophyte stage begins when the egg is fertilized by a sperm.
In some plant life cycles, the sporophyte and gametophyte stages are separate and not dependent on each other. In other plant life cycles, they are part of the same organism.

38. Seedless Reproduction
Reviewing Main Ideas 2
Seedless Reproduction
For liverworts and mosses, the gametophyte stage is the familiar plant form. The sporophyte stage produces spores.
In ferns, the sporophyte stage is the familiar plant form.
Seedless plants, like mosses, and ferns, use sexual reproduction to produce spores.

39. Reviewing Main Ideas 3
Seed Reproduction
In seed plants the male reproductive organs produce pollen grains that eventually contain sperm. Eggs are produced in the ovules of the female reproductive organs.
The male and female reproductive organs of gymnosperms are called cones. Wind usually moves pollen from the male cone to the female cone for pollination.

40. Reviewing Main Ideas 3
Seed Reproduction
The reproductive organs of angiosperms are in a flower. The male reproductive organ is the stamen, and the female reproductive organ is the pistil. Gravity, wind, rain, and animals can pollinate a flower.
Seeds of gymnosperms and angiosperms are dispersed in many ways. Wind, water, and animals spread seeds. Some plants can eject their seeds.

Question 1
_______ reproduction requires the production of sex cells, usually called sperm and eggs.
A. Asexual
B. Cloning
C. Sexual
D. Spore
LE 4.1c

Question 4
_______ is a series of events that results in the growth of a plant from a seed.
A. Cultivation
B. Fertilization
C. Germination
D. Pollination
LE 4.1

59. Standardized Test Practice
Answer
The answer is C. Germination begins when seed tissues absorb water, causing the seed to swell and the seed coat to break open. Seeds will not germinate until environmental conditions are right.
