WGU D518 A3 EXAM PREPARATION TEST
BANK WITH CORRECT ANSWERS
●● 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
●● Peptidoglycan of bacteria
Answer: is part of the cell wall.
is made of sugars and proteins.
