Question

Bacteria and Archae

Be able to classify Bacteria, Archae and Eukaryotes into the correct domain based on given characteristics.

Know the meaning of the terms thermophile, halophile and methanogen.

Know the importance of bacteria to humans (your gut microbiome affects your health, but bacteria can also be pathogenic, etc)

Protists

You will be given the phylogenetic tree below and asked to use it to classify examples into the correct supergroup of Figure 28.2 (SAR, Unikonta, Archaeplastida and Excavata) based on given characteristics.

Plant Diversity

Know the phylum, domain and supergroup of land plants and its sister taxon.

Describe at least four out of the seven derived traits of land plants.

Describe and draw a general land plant life cycle (know the terms haploid, diploid, gametophyte, sporophyte, spore, meiosis, mitosis)

List an example of nonvascular plants, seedless vascular plants and seed plants.

Compare and contrast information regarding the life cycles of nonvascular plants, seedless vascular plants and seed plants (the comparison chart I gave you in class).

Define xylem and phloem.

Seed Plants

Describe the evolutionary advantage of seed, pollen, flowers and fruit.

Know the importance of seed plants to humans.

Fungi

Describe the body structure of fungi such as cell walls made of chitin, mycelia, hyphae, and haustoria

Know the domain and supergroup of fungi and its sister taxon.

Describe the way that fungi receive nutrition.

Describe the mutualistic relationship between fungi and plants that form lichen.

Know the importance of fungi to humans.

6. “What Plants Talk About”

Describe a characteristic of plants you did not previously know. Only detailed, specific essays of ten sentences or longer will receive full credit. Please do not bring the essay to class, but be prepared to write it.

Answer 1

Bacteria, Archae and eukaryotes are classified by Three domain system of classification.
Three domain system of classification is given by Carl woese in 1990. This system of classification is for giving different class to living organsims.
Three domain system of classification is based on difference in ribosomal RNA structure
As per three domain system of classification
organisms are classified into three domains and 6 kingdoms
Domains

• Archaea
• Bacteria
• Eukarya

Kingdom

• Eubacteria
• Archaebacteria
• Fungi
• Protista
• Animalia
• Plantae

Archaea Characteristics
They are single celled organisms like bacteria and some eukaryotes. They differ from bacteria and eukaryotes in membrane composition and Ribosomal RNA structure.
They have 3 phyla
1) Crenarchaeota
2) Euryarchaeota
3) Korarchaeota

Bacteria characteristics

* Unique Ribosomal RNA structure
* Unique Cell wall and composition.
* They are 5 different types
1) Proteobacteria
2) Cyanobacteria
3) Firmicutes
4) Chlamydiae
5) Spirochetes

Eukarya Characteristics

* Membrane bound nucleus
* Divided into following kingdoms
1) Fungi
2) Protista
3)Animalia
4) Plantae

Thermophile: Organisms which lives in or loves high temperatures.
Halophile: Organisms which lives in or loves high salt concentrations
Methanogen: Organism which produces methane as byproduct in case of less oxygen condition.
