2.What are the four main challenges that came about for plants to live on land?

3.What are three adaptations that all plants have made to be more successful on land?

4.True or False Correct if false

Spores and seeds are the same

SEEDED VASCULAR PLANTS:

1.For both groups which phase is dominant?

2.Compare and contrast homosport and heterospory. Which plants are heterosporous? Which plants are homosporous? Which group has a bisexual gametophyte?

3.Megaspores grow into ______gametophytes. Microspores grow into ______gametophytes.

2.True or False:

Both gymnosperms and angiosperms have the same kind of seed.

3.What three things makes up a seed and give the definition of a seed

4.Once you have an embryo it will grow into a mature ______

5.Gymnosperm life cycle is very similar to angiosperm life cycle except for one major difference what is it?

6.Draw a concept map of the alternation of generations of gymnosoperms using the following words starting with the mature sporophyte phase:

  1. Mature sporophyte
  2. Ovules
  3. Ovulate cone

  16. Haploid
  17. Developing sporophyte

7.A conifer tree producecs both ______and _____female______gametophytes called ______and ______

SEEDLESS NON VASCULAR:

1.What is the main issue with these plants compared to the other two extant groups?

2.What adaptations have now come about for this group?

3.Anthocerophyta

Dominant Life cycle:

Common Name:

4.Hepaticophyta

Dominant Life Cycle:

Common examples:

Sporophytes:

Asexual Reproduction?

Sexual Reproduction?

5.Bryophyta

Dominant Life cycle:

Common Name:

Sporophytes:

Sexual Reproduction:

6.Which is the archegoium for moss and which is the antheridium, how do you know?

SEEDLESS VASCULAR:

1What adaptations have now occurred on top of the ones present in bryophytes?

2.What is their true vascular system made of? What is the functions of each?

3.True or false

For members of this extant group some species can be homosporous and some can be heterosporous. Homosporous can be thought of as being bisexual

4.PTERIDOPHYTA

Common Name:

Dominant Life cycle:

Spore fate:

5.What structure do some species have to help with seed dispersal?

6.For most seedless vascular plants where are spore produced and how?

7.LYCOPHYTA

Common Name:

Dominant life cycle:

Spore fate:

Gametophytes:

VIRUSES:

1.What are the three parts of a virus we learned and how can they vary?

2.What is an advantage to being virulent and a disadvantage for being too virulent?

3.True or False:

A viral infection can live on a bacterial free desk for days and replicate many times to where it will eventually infect the whole desk.
