Has cell wall

(y/n)

Has

Nucleus

(Y/n)

Has DNA

(Y/N/

sometimes)

Describe defining structures and characteristics of each group of organism

Made of cells

(y/n)

Has

Nucleus

(Y/n)

Has DNA

(Y/N/

sometimes)

Describe defining structures and characteristics of each group of organism

Bacteria

Present nad made up of peptidoglycan

True membrane bound nucleus absent

DNA present as a thread like structure called nucleoid that floats freely, also circular DNA is present known as plasmid.

Microscopic, simple, membrane bound organelles are absent, ribosome 70s, dna complexed with histone is absent, diameter ranges from 0.2-2 micrometres, growth by binary fission,flagella is used for locomotion, bot harmful and friendly assosciation with human

Single celled organism called as unicellular

Archaea

Cell wall composed of

Pseudomurein instead of peptidoglycan

absent

Histone assosciated dna is present

Same as bacteria, present in extreme environment and not infect human

prokaryotic

Algae

Cell wall components are cellulose, alginic acid.

present

Chlorophyll bearing, thalloid body, non vascular( xylem, phloem absent),embryonic development absent, locomotion by flagella, both sexual and asexual reproduction. Eg. Volvox, spirogyra, etc

multicellular

Protozoa

absent

present

Aquatic, free living, parasitic, heterotrophic, locomotion by cillia, flagella,pseudopodia, reproduction by both sexual and asexual, infects human like malaria, amoebiasis,etc

unicellular

Viruses

Absent, protein coat is presemt

no

ssDNA, ds DNA or ssRNA and ds RNA

Simple, and active inside host body, link between living and non living, all virus contains nucliec acid covered bya protein capsid called nucleocapsid, cause diseases in animal, bacteria and plants eg. HIV, TMV,etc

Nor unicellular

nor multicellular

Viroids

no

ss RNA

Smaller than virus

and infectious

particle

Prions

Protein present

no

NO

Similar to a virus

Lacking nucleic

acid,An infectious

particle

Cells and Viruses Observe and draw the following cells. Plant cell (slide) – Note cell wall, chloroplast What does this tell you about the functions of this cell? Pancreatic cell (slide) – Note large amounts of endoplasmic reticulum and ribosomes. What do these structures reveal about its function? Virus (Electron micrograph) – Note the lack of organelles. Why do viruses need to infect a host cell to reproduce? Table 1 Drawing of Cell Include total magnification Organelles observed Summarize your...

1. The part of the cell cycle where DNA is duplicated inside the nucleus in preparation for cell division? 2. Most of the cell's life cycle spent in which phase? 3. During this part of the cell cycle phase, no nuclear envelope is visible and chromosomes align in the center of the cell and attach the the spindle by their centromeres? 4. Chromosomes are separated and pulled apart during this period of the cell cycle?

1.How do reproductive cloning and therapeutic cloning differ? a. The DNA in the nucleus of cells produced for therapeutic cloning is genetically identical to the donor genome, whereas in cells produced for reproductive cloning it is not. b. Reproductive cloning requires a supply of fertilized donor egg cells, whereas therapeutic cloning requires unfertilized egg cells. c. Therapeutic cloning requires nuclear transplantation, whereas reproductive cloning does not. d. Embryos are placed into foster mothers during reproductive cloning but not during therapeutic...

A laboratory drying oven has a composite wall made of Plane Wall 1 and Plane Wall 2 as shown above. A thin film heater (surface heat source, thickness negligible) is sandwiched between the two plane walls 1 and 2. Plane Wall 1 has a thickness L1 = 0.02 m and a thermal conductivity k1 = 0.05 W/m·K, while Plane Wall 2 has a thickness L2 = 0.01 m and a thermal conductivity k2 = 0.1 W/m·K. During steady state operation,...
