CH 29 BIOL 1202
General Biology II Lecture
CHAPTER 29
Plant Diversity I How Plants Colonized Land
Dr. Adam Hrincevich
, CH 29 Learning Objectives
1. Identify key derived characters of plants.
2. Characterize the life cycles of nonvascular plants.
3. Describe characteristics and reproductive processes
of seedless vascular plants.
I would suggest completing the crossword puzzle to help
you understand the terminology and correlate how the
terms relate to topics covered in this chapter.
,The Greening of Earth
For much of Earth’s history, the terrestrial surface was
lifeless
Cyanobacteria and protists likely existed on land by
1.2 billion years ago
Small plants, fungi, and animals emerged on land
only within the last 500 million years
Since colonizing land, plants have diversified into
more than 290,000 living species, most live on land
Algae are NOT included in the plant kingdom; they
are photosynthetic protists
Plants supply oxygen (but how much?) and are the
ultimate source of most food eaten by land animals
, 4 Where does earth's oxygen come from?
