  1. If you had the flu, which is a virus, how can you treat it?
  1. Even though viruses are not cells, what cellular function do they have? How can this function vary?

KINGDOM PLANTAE

  1. What are the three different types of plants. Name them in order from oldest to most recent
  1. What does it mean when Colbert says a general characteristic of plants is they have complex bodies with extensive specialization of cells?
  1. Provide an example of a plant that is not a photoautotroph. How may you know its not by looking at the picture
  1. What are the four main challenges that came about for plants to live on land?
  1. What are three adaptations that all plants have made to be more successful on land?
  1. True or False Correct if false

Spores and seeds are the same

SEEDLESS NONVASCULAR PLANTS

  1. What is the main issue with these plants compared to the other two extant groups?
  1. What adaptations have now come about for this group?
  1. Anthocerophyta

Dominant Life cycle:

Common Name:

Hepaticophyta

Dominant Life Cycle:

Common examples:

Ecosystem:

Sprorphytes:

Asexual Reproduction?

Sexual Reproduction?

Bryophyta

Dominant Life cycle:

Sporophytes:

Hydroids:

Sexual Reproduction:

  1. Which is the archegoium for moss and which is the antheridium, how do you know? Label one oother structure that is visible

SEEDLESS VASCULAR

  1. What adaptations have now occurred on top of the ones present in bryophytes?
  1. What is their true vascular system made of? What is the functions of each?
  1. What are the two water conducting cells? What other function do they serve besides transporting water, how do you know this?
  1. 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

  1. Spore production: Because of the spore fate where are spores produced and how?
  1. What is this an image of? What does it produce?
  1. What structure do some species have to help with seed dispersal?
  1. What is the difference between these two images even though they are both part of the same phylum
  1. When first looking at the fern life cycle it is bad because ______are produced by ______creating __ genetic variance. To fix this issue they produce ______.

  1. All angiosperms are members of phylum ______
  1. Angiosperms have become the most/least abundant because:
  1. Gymnosperm life cycle is very similar to angiosperm life cycle except for one major difference what is it?
  1. ______mature into ______and ______mature into fruits
  1. In a flowering plant what structure is the female gametophyte in?
  1. What is this structure below and what is the importance of that tube?
  1. In the male gametophyte, two sperm cells are present what is the fate for each in angiosperms and in gymnosperms
