virus, algae, fungi, protozoa, bacteria
how are prokaryotes and eukaryotes similar?
both have cell membranes both have ribosomes
how are prokaryotes and eukaryotes different?
Prokaryote: No nucleus, single loop chromosome, binary fission , smaller
Eukaryote: Nucleus with two pairs of chromosomes, asexual and sexual reproduction,
multicellular, larger
What are viruses?
noncellular, need host for replication
what is algae
uni or multi, fresh and ocean water, photosynthetic, simple reproductive structures,
categorized based on pigmentation, storage, and cell comp
what is protozoa
single celled eukaryotes, similar to animals in structure and nutrition, typically in water,
asexual some sexual, locomotion from pseudopodia cilia flagella
What is fungi?
eukaryotic, single celled, food from other organisms, cell walls, molds and yeasts
what is bacteria
, prokaryotic, chemotrophs, single celled, shape cell wall motility
what are the bacterial shapes
coccus, bacillus, spiral
what are common cell components
macromolecules, proteins, carbohydrates, lipids
what are the bacterial cell components from inside out
nucleoid, cytoplasm, inner cell membrane, cell wall, sometimes periplasm, sometime capsule,
sometimes flagella
what types of nutrients are required for a microorganism to grow
water, energy source, carbon source, nitrogen, minerals, vitamins
what are energy sources
chemotrophs (break chemical bonds) or phototrophs (photosynthetic pigments)
what are carbon sources
hetrotrophs (organic carbon, carbs, proteins, fats, DNA, amino acids) or autotrophs (obtain
carbon by fixing co2)
