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
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 wa lls
have peptidoglycan and described by shape (coccus, bacillus,
spirillum, spirochete or vibrio)
Protists
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"
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
Ans: phospholipid bilayer with embedded proteins that defines
the boundary of the cell
Cell wall of bacteria
Ans: made of peptidoglycan and help maintain shape and
withstand changes in osmotic pressure
Peptidoglycan of bacteria
Ans: is part of the cell wall.
is made of sugars and proteins.
Flagella of bacteria
Ans: acts as a propeller to move the cell. Stiff, rotating
structure.
Fimbriae of bacteria
Ans: hairlike bristles that allow adhesion to surfaces
Pili of bacteria
