PASS
What are characteristics of Prokaryotic Cells "Bacteria"—ANSWER--Single celled, do not have
nucleus, mitochondria or chloroplast, multiple shapes (coccus, bacillus, vibrio, etc) found in
pairs, clusters or chains
What are characteristics of Eukaryotic cells "animal and plant cells"—ANSWER--Have a
nucleus, have membrane bound organelles, single celled or multicellular, larger than
prokaryotes, linear histone wrapped chromosomes
Differences between Prokaryotes and Eukaryotes—ANSWER--All plants and animal cells
(protozoans , algae, fungi) are Eukaryotic.
bacteria and archaea are Prokaryotic
Structures if Eukaryotic: nucleus, membrane organelles in the cytoplasm ( mitochondria,
endoplasmic reticulum, Golgi apparatus, lysomes, and peroxisomes held in place by the
cytoskeleton. Flagella (whip like/flexible) and cilla
Structures of Prokaryotic: cell membrane, chromosomal dna that is in nucleotide,
ribosomes, and cell wall. Flagella (stiff/rotating) pilli, fimbriae and capsules
, Bacteria—ANSWER--Found in every habitat on earth, prokaryotic, cell walls have
peptidoglycan and described by shape (coccus, bacillus, spirillum, spirochete or vibrio)
Protists—ANSWER--A eukaryotic organism that cannot be classified as an animal, plant, or
fungus.
Fungi—ANSWER--Eukaryotic, lives by decomposing and absorbing nutrients. Not
photosynthetic and has cell wall made of chitin
Helminths—ANSWER--multicellular parasitic organisms commonly called worms or flukes
ex: Guinea worm (Dracunculus medinensis)
Viruses—ANSWER--Acellular, consists of proteins and genetic material (dna/rna) never both
Bacterial Structures "prokaryotic"—ANSWER--Nucleoid, ribosomes, endospores, plasma
membrane, cell wall, peptidoglycan, flagella, fimbriae, pilli
Nucleoid of Bacteria—ANSWER--central area in a prokaryotic cell that contains genetic
information, not surrounded by a membrane
Ribosomes of Bacteria—ANSWER--site of protein synthesis. 70S composed of two subunits
(30S small and 50S large and are composed of protein and rRNA components
Endospores of bacteria—ANSWER--form around DNA when stressed, protect until
conditions are good
Plasma membrane in bacteria—ANSWER--phospholipid bilayer with embedded proteins that
defines the boundary of the cell
Cell wall of bacteria—ANSWER--made of peptidoglycan and help maintain shape and
withstand changes in osmotic pressure
