BISC 101 EXAM UPDATED QUESTIONS WITH
COMPLETE SOLUTIONS.
What is a shoot system
- stems and leaves
-absorbs light and c02
-photosynthetic
-reproductive shoots bears flowers for reproduction
what is the root system
-absorbs water and minerals from soil
-non-photosynthetic
-anchors vascular plants in soil
-storage organ (tap root)
the vascular system
-connects 2 systems carrying water/minerals from roots to leaves(xylem) and photosynthates in
both directions between roots and shoots(phloem)
what is prop roots and buttress roots
-provide structural support
-holds up trees in shallow, unstable
Storage roots
store food and water
,pnemataphores
project above surface of swamps to obtain 02
aerial roots
sent out by strangler fig seedling growing at top in tree tops
rhizomes
horizontal shoots which grow underground
shoot or stems
bulbs
vertical underground shoots consisting of enlarged leaf base
-shoot or stem
stolons
horizontal shoots that grow allow surface giving rise to new plants (asexual reproduction)
-shoots or stem
tubers
enlarged ends of rhizomes or stolons
-shoot or stem
trendrils
in climbing plants
ex. peas
-leaves
, spines
provides protection
ex. in cacti
-leave
storage leaves
stores water
ex. in succulent, fleshy plants
reproductive leaves
small adventious plantlets fall off leaf and take root
bracts
flower like, modified leaves
what is dermal tissue
-plants outer protective covering
-in non woody plants it has a one layer epidermis which can have a waxy cuticle that reduces
water loss
-woody plants have periderm
what is vascular tissue
- carries out long distance transport
-phloem and xylem
what is ground tissue
