We base our modern taxonomy on the work of
Gregor Mendel
Luther Burbank
Charles Shuabb
Carl Linnaeus
One problem with Linnaeus' system of naming was that he classified organisms based on
the way they ate
the way they appeared or morphology
the way they reproduced
the way they swam
Many other scientists helped to improve Linnaeus system. The latest one is
Gregor Mendel
Carl Woese
Carl Linnaeus
Mamie Powell
The four main groups of plants (land plants) to be familiar with are Gymnosperms, Angiosperms and (more than one answer)
Animalia
Bryophytes (mosses)
Ferns
Fungi
Some land plant characteristics are they are all eukaryotic, autotrophs, have a cell wall, are terrestrial and (more than one answer)
are embryophytes
produce flowers
exhibit alteration of generations
produce cones or "naked" seeds
Alteration of Generations means that there are two forms of life cycle they are (more than one answer)
gametophyte (haploid)
sporophyte (diploid)
bryophyte
gymnosperm
Plants are able to go through a chemical process to convert CO2 and water into simple sugars. This process is known as
photosynthesis
cell respiration
mitosis
meiosis
Plants, just like all living things go through a chemical reaction in the cell to use the simple sugars to drive the mechanism to produce energy molecules...ATP. This process is
photosynthesis
carbon dioxide
cell respiration
mitosis
The four types of land plants represent "steps" on land that evolved. The first step was to be on land and the plants that represent that step are
Bryophytes (mosses)
Ferns
Gymnosperms
Angiosperms
The second step land plants took was to develop vascular tissue to move water and nutrients thoughout the plant. These plants are
Bryophytes
Ferns
Gymnosperms
Angiosperms
The third step land plants took was to develop seeds. Containers to protect the plant embryo. Plants that represent this step are
Angiosperms
Mosses
Ferns
Gymnosperms
The fourth step land plants took was to develop flowers to attrack pollinators and to form very complex seed containers to supply plenty of food for the embryo. These are known as
Angiosperms
Mosses
Gymnosperms
Ferns
