GRADED A+ | GUARANTEED 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
Peptidoglycan of bacteria - ANSWER-is part of the cell wall.
is made of sugars and proteins.
Flagella of bacteria - ANSWER-acts as a propeller to move the cell. Stiff, rotating
structure.
Fimbriae of bacteria - ANSWER-hairlike bristles that allow adhesion to surfaces
Pili of bacteria - ANSWER-Appendages that allow bacteria to attach to each other
and to transfer DNA
Chemotaxis - ANSWER-Directional movt from a call in response to chemical
attraction
Phototaxis - ANSWER-movement in response to light using flagella
