structure of flowering plants Flashcards
what is the meristem
region where mitosis can occur
give two locations in plants where meristematic tissue may be found
root tip
shoot tip
give a function for a dermal tissue
forms the outer epidermis for protection
give a function for the ground tissue
carries out photosynthesis
give a function for the root hair
absorption
give one function of vascular tissue in plants
transport
name the two types of vascular tissue present in plants
xylem, phloem
what did you observe under the microscope that showed you it was a dicot stem
vascular bundles in a circle
give two structural features of xylem that allow this upward movement of water
thick walls
presence of lignin
distinguish between monocots and dicots plants, by writing a sentence on leaf vein type
monocots - parallel
dicots - branched
distinguish between monocots and dicots plants, by writing a sentence on organisation of vascular bundles in the stem
monocots - random
dicots - in a circle
indicate two ways plants use to control transpiration
waxy cuticle
action of stomata
give two structural difference between xylem and phloem
xylem - dead, has lignin
phloem - living, has not lignin
in which zone is water absorbed from the soil
differentiation
name the process through which water is absorbed from the soil
osmosis
name the tissue that transports water in roots
xylem
describe the mechanism by which water moves through the tissue to the leaves in a plant
water molecules stick together(cohesion)
water molecules stick to side of xylem(adhesion)
water evaporates(transpiration) and pulls water upwards
what is meant by the term dicot
seeds have two cotyledon
name the part of the microscope you used to bring the section into a sharp focus
fine knob
name the vascular tissue through which the products of photosynthesis are transported in plants
phloem
give two structural features of the phloem
sieve tubes
sieve plates
