COMPLETE QUESTIONS AND SOLUTIONS
◉ 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.
