animal-like protist; a type of protozoa that moves using hairlike cilia
euglena. plant-like: photosynthetic and contains chloroplastsanimal-like: flagella
A moss, liverwort, or hornwort; a nonvascular plant that inhabits the land but lacks many of the terrestrial adaptations of vascular plants; no seeds, vascular tissue, or flowers
-they have pigments like chlorophyll a and phycobilins-they fix nitrogen and produce oxygen
Area on the inside of a stem where new xylem and phloem are made
-Eukaryotic, multicellular (except yeast) heterotrophs -chitin cell walls -no chlorophyll-store energy as glycogen-terrestrial-saprophytic-sexual and asexual reproduction
Domain of unicellular prokaryotes that have cell walls that do not contain peptidoglycan; extremists
Accessory pigment that absorbs blue light, found in red algae and cyanobacteria
unicellular, aquatic and produce flagellated zoospores; they were the first fungi; non-septate
Domain of unicellular prokaryotes that have cell walls containing peptidoglycan
PROKARYOTES ("pro" = before, "karyon" = nucleus) 1. Unicellular: Bacteria and blue-green algae 2. No nucleus; nucleiod region with single circular DNA; single chromosome; 3. Smaller 4. Cell wall in all 5. Ribosomes (70S) 6. No membrane-bound organellesEUKARYOTES ("eu" = true, "karyon" = nucleus) 1. Unicellular or Multicellular: protists, fungi, plants & animals 2. Nucleus; consist of mutiple chromosomes 3. Bigger 4. Cell wall ONLY in fungi & plants 5. Ribosomes (80S) 6. Membrane-bound organelles BOTH 1. Cytoplasm 2. DNA 3. Cell membrane 4. ribosomes5. Activities of living things
the layer of cells that make up the top and bottom surface of the leaf
A small ring of DNA that carries accessory genes separate from those of the bacterial chromosome
the cells that control the opening in a leaf that allows gas exchange
golden algae; A unicellular photosynthetic alga with a unique glassy cell wall containing silica
the openings in a leaf that allows gas exchange to occur
slime molds and water molds examples: oomycetes; a water mold that causes "ick" in fish
characteristic nucleotide sequences in the ribosomal RNA genes, or their products, that can be used to classify or identify certain organisms
