Students have asked these similar questions
What types of evidence support the hypothesis that land plants descended from the group of green algae known as charophytes?
Match the following clades with the characteristics that they share
Clades:
Bryophytes and Tracheophyta
Embryophyta and Charophycea
Chlorophyta and Streptophyta
Bryophytes and Tracheophyta
Characteristics:
-Chlorophylls a and b are autotrophic
-Alternation of generations
-Rosettes in the plasma membrane
-Sporangia with walled spores
Horsetalls are a group of seedless vascular plants are often representative of a separate
evolutionary line of Pteridophytes. The photo below illustrates an unusual difference
between the Pteridophytes and the Equisetales.
Which answer below best represents this unusual difference?
a Equisetales have a separate vegetative and fertile shoots
Equisetales are gametophyte dominant
Equisetales don't produce spores
Equisetale sporophytes are nutritionally dependent upon the gametophyte phase

They have lignin in their cell walls.

On your survey, you come across a plant you are not familiar with and must do some research to figure out what it is. To do this, your first step is to determine whether this plant is classified in the class Monocotyledonae or a Eudicotyledonae. Explain how you can tell if this plant is a Monocot or Eudicot by describing the differences in their flowers, seeds, roots, stems, and leaves. 1.arrow_forward
