Bio Sat Flashcards
Describe mycorrhizae
Symbiotic structures that live in plant roots,increase uptake of nutrients
Verterbrate order of evolution
Bony fish Amphibians Reptiles Birds Mammals
Plant tissue that under goes mitosis constantly
Cambium
Dead vascular tissue
Xylem, transports wAter
P^2+2pq+q^2
P-homozygous dominant
Q-homozygous recessive
Pq-heterozygous
Microvilli?
Small intestine-located on each ‘villus’ to absorb nutrients, contains capillaries
Grasshopper classification Phylum? Nitrogenous waste disposal? Circulation? Nervous system?
Phylum-Arthropoda
N waste-malphighian tubes
Circ-open circulatory system
Nervous-brain+ventral nerve chord
Nephridia
Earthworm waste disposal
Hydra
Phylum?
Phylum Cnidaria,
Cnidocytes/nematocysts=stinging cells
Tissue layers in organisms
Ectoderm
Endoderm
Mesoglea
Bryphophytes?
Plants that lack vascular tissue, No roots Tiny Primitive Ex. Mosses
Tracheophytes
Sub division?
Vascular tissue Seedless plants:ferns Sub div: Gymnosperm:conifers Angiosperms: flowering plants
Monocot vs eudicot
Monocot: single cotyledon(seedl leaf),scattered vascular bundles,parallel leaf veniation,3s of florals, fibrous roots
Eudicot?
2 cotyledon,ring vascular bundles, netlike leaf venation, 4s or 5s floral,taproots
Wheat corn oats grass rice
MONOCOTS
Daisies, roses carrots trees
Dicot EUDICOTS
Meristem tissue
Tissue that continuously divides
Parenchyma cells
Plant cells containing many plastids for storage
Caspirian strip?
Wrapped around each endoderm cell that surrounds the vascular cylinder
Plasmodesmata
Interconnection between plant cells
Rhizobium
Symbiotic bacterium growing on roots of legumes to fix nitrogen
Xylem cells?
Tracheids, vessel elements
Phloem cells
Phloem cells?
Sieve tube elements and companion cells
