Lab Practical Flashcards
zone of inhibition
- distance between edge of disc and nearest bacterial growth
- larger ZOI = stronger anti-bacterial properties
immune structures in the body
- bone marrow
- leukocytes (white blood cells)
- thymus
- lymph nodes
- spleen
- tonsils
neutrophils
- multi lobed nucleus
- light pink background
- most abundant WBC
eosinophils
- two lobed nucleus
- redder back =ground
basophil
- dots covering cell
- two lobed nucleus
- purple speckled background
lymphocytes
- smaller with large dark nucleus
- light blue background
monocytes
- kidney/ heart shaped nucleus
- blue background
platelet
-small dot in-between red blood cells
reticular fibers in a lymph node
- allow filtration of lymph stem and pathogen debris
- thread-like
erythrocytes
- red blood cells
- most important for oxygen transport
stems
- modified asexual reproduction
- ex. onion
roots
- modified for storage
- ex. carrot
leaves
- modified for storage
- ex. celery
calyx
-whorl of sepals
corolla
-whorl of petals
carpel
- inside stick
- made up of: ovary, style, stigma (top)
stamen
- thin inside string with bulb on top
- made of: filament, anther (top)
sepal
- green leaflike bottom part
- connected to form calyx
petal
- each segment of the corolla
- modified leaves
receptacle
- contains ovary
- sits in calyx/ whorl of sepals
lip
-enlarged petal
fruit
- mature ovary containing seeds
- evolved to protect or disperse seeds
- thickened ovary walls (pericarp)
what is the pericarp of a fruit made of
- exocarp (outermost)
- mesocarp
- endocarp (surrounding seed)
simple fruit
- each flower contains one ovary
- can be either fleshy, dry, nut,
fleshy
- soft, fleshy ovary wall/ pericarp
- ex. berry (grape, tomato), hesperidium (lemon, lime), pepo (cucumbers), pome (apple, pear), drupe (nectarine, cherry)
dry fruits
- pericarp splits open along definite seams
- legume (bean pod), achenes
nut
- larger, one-seeded fruit with very hard pericarp (usually enclosed in husk)
- ex. acorn, chestnut, walnut
aggregate fruits
- cluster of many ripened ovaries (fruits) produced by a single flower
- ex. raspberries, blackberries
multiple fruits
- cluster of many ripened ovaries (fruits) produced by many flowers crowded together
- ex. pineapple
xylem
- larger holes/ white spaces on outside of slide
- vascular tissue in plants that
- sap movement via transpirational pull (up from roots to leaves)
- cohesion tension pulls water from soil into roots xylem
phloem
- smaller holes/ white spaces on inside of slide
- sap movement via pressure flow (down from leaves to roots)
- sugar passes through sieve-tube members
active transport of sucrose (translocation)
- from source cell -> companion cell -> phloem
- down the phloem through sieve tubules/ pores
- phloem -> companion cell -> sink (root cell)
transpiration
- high rate potential inside the leaf, low water potential outside leaf
- water leaves menisci (space inside leaf) and goes into air
primary growth
-growing longer or taller roots or shoots
