Bacteria & Archaea
This molecule makes up the bacterial cell wall but is absent in Archaea.
What is peptidoglycan?
Protists belong to this domain.
What is Eukarya?
Plants evolved from this group of green algae.
What are charophytes?
This structure carries the male gametophyte.
What is pollen?
Which domain lacks a nucleus?
What are Bacteria and Archaea?
This bacterial shape is rod-shaped.
What is a bacillus?
These microscopic algae have silica cell walls.
What are diatoms?
This waxy coating prevents water loss in land plants.
What is the cuticle?
Seeds contain these three major components.
What are the embryo, food supply, and seed coat?
Which protist group is most closely related to land plants?
What are charophytes?
Gram-negative bacteria have this extra layer that Gram-positive bacteria lack.
What is the outer membrane?
This group is famous for causing red tides.
What are dinoflagellates?
These molecules protect spores from drying out.
What is sporopollenin?
Gymnosperms differ from angiosperms because they have these instead of flowers.
What are cones?
Seedless vascular plants still require this for fertilization.
What is water?
Horizontal gene transfer involving uptake of naked DNA is called this.
What is transformation?
According to endosymbiotic theory, chloroplasts evolved from this type of organism.
What are cyanobacteria?
Land plants exhibit this life cycle with multicellular haploid and diploid stages.
What is alternation of generations?
Double fertilization occurs only in this group.
What are angiosperms?
A student finds an organism with silica walls that performs photosynthesis. Identify it.
What is a diatom?
Why are Archaea often found in extreme environments but also common in normal habitats?
Because they possess unique membrane lipids and cell wall chemistry, allowing survival in many environments.
Name the four major eukaryotic supergroups discussed in class.
What are Excavata, SAR, Archaeplastida, and Unikonta?
Name all five derived characteristics of land plants.
One sperm forms the embryo while the other forms this tissue.
What is endosperm?
A plant has flowers, fruit, pollen, seeds enclosed within an ovary, and double fertilization. Identify the group.
What are angiosperms?
