3 key differences between plant and animal cells
cell wall chloroplast vaculoe
100
-molecule not required for primary functions to stay alive, but often provide beneficial function (some may necessary in certain species) -restricted in distribution among and with in plants
secondary metabolite -what are major/common functions of these?
100
plant bodies are divided into these two systems
root and shoot
100
apical protoderm, ground, procambium
meristem at shoot/root tips - contains initials and derivatives three primary meristems - partiall differentiated
100
Root cap Region of cell division Region of cell elongation Region of maturation
four regions of longitudinal root structure (know main function of each)
200
the ONE key thing that plant cells have that makes plant cells fundamentally different than animal cells
cell wall
200
three classes of secondary metabolites
alkaloids, terpenoids, phenolics (know example of each)
200
plant organs
roots, stem, leaves (know basic functions)
200
epidermis, ground tissues, primary xylem and phloem
primary tissues
200
epidermis cortex vascular cylinder pith (if present)
transverse structures of root (cross-section) (know primary functions and components of each)
300
cell wall laid down during growth
primary cell wall
300
embryogenesis and seed maturation
two stages of seed development
300
parenchyma, collenchyma, sclerenchyma,
three gound tissues - simple tissues -where are they found? -cell types? -functions?
300
aerial roots, air roots, fleshy roots
specialized root types/modifications -what does each do?
400
cell wall laid down during secondary growth
secondary cell wall
400
photosynthesis first evolved ~ ______ years ago was this a unicellular or multicellular organism?
3.4 billion unicellular
400
primary xylem and phloem
primary vascular tissues - complex tissues -functions -different cell types
400
roots that do most of absorption
fine roots
500
chloroplasts, chromoplasts, leucoplasts
plastids (know primary functions)
500
aspects of plant bodies and function that are different from animals
nutritional mode - absorptive photoautotroph stationary high SA/volume growth in meristems - local and indeterminant primary and secondary growth
500
epidermis, periderm
dermal tissues -functions? -primary or secondary?
500
Suberin bands in transverse and radial cell walls and middle lamella of endodermis
casparian strip - what does this do?
