Textbook Question
Chapter 25, Problem 11RQ
Which of the following features does not support the inclusion of Charophytes in the Plantae kingdom?
- Charophyte chloroplasts contain chlorophyll a and b
- Charophyte plant cell walls contain plasmodesmata to allow transfer between cells within multicellular organisms
- Charophytes do not exhibit growth throughout the entire plant body
- Charophytes are multicellular organisms that lack vascular tissue.

Students have asked these similar questions
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
The Riccia is a bryophyte because:
It has multicellular sex organs
with a sterile jacket and lacks
vascular tissues
Its sporophyte lacks
differentiation and has a single-
layered jacket
It occurs mostly on land and has
more motile sperm
It has a heteromorphic alternation
of generation and lacks leaves
Next
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
