What are characteristics of Prokaryotic Cells "Bacteria"
Ans: 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"
Ans: Have a nucleus, have membrane bound organelles, single celled or
multicellular, larger than prokaryotes, linear histone wrapped
chromosomes
Differences between Prokaryotes and Eukaryotes
,2 | Page
Ans: 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
Ans: Found in every habitat on earth, prokaryotic, cell walls have
peptidoglycan and described by shape (coccus, bacillus, spirillum,
spirochete or vibrio)
Protists
,3 | Page
Ans: A eukaryotic organism that cannot be classified as an animal, plant,
or fungus.
Fungi
Ans: Eukaryotic, lives by decomposing and absorbing nutrients. Not
photosynthetic and has cell wall made of chitin
Helminths
Ans: multicellular parasitic organisms commonly called worms or flukes
ex: Guinea worm (Dracunculus medinensis)
Viruses
Ans: Acellular, consists of proteins and genetic material (dna/rna) never
both
Bacterial Structures "prokaryotic"
, 4 | Page
Ans: Nucleoid, ribosomes, endospores, plasma membrane, cell wall,
peptidoglycan, flagella, fimbriae, pilli
Nucleoid of Bacteria
Ans: central area in a prokaryotic cell that contains genetic information,
not surrounded by a membrane
Ribosomes of Bacteria
Ans: 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
Ans: form around DNA when stressed, protect until conditions are good
Plasma membrane in bacteria
