structure of flowering plants

Question 1

what is the meristem

Answer 1

region where mitosis can occur

Question 2

give two locations in plants where meristematic tissue may be found

Answer 2

root tip
shoot tip

Question 3

give a function for a dermal tissue

Answer 3

forms the outer epidermis for protection

Question 4

give a function for the ground tissue

Answer 4

carries out photosynthesis

Question 5

give a function for the root hair

Answer 5

absorption

Question 6

give one function of vascular tissue in plants

Answer 6

transport

Question 7

name the two types of vascular tissue present in plants

Answer 7

xylem, phloem

Question 8

what did you observe under the microscope that showed you it was a dicot stem

Answer 8

vascular bundles in a circle

Question 9

give two structural features of xylem that allow this upward movement of water

Answer 9

thick walls
presence of lignin

Question 10

distinguish between monocots and dicots plants, by writing a sentence on leaf vein type

Answer 10

monocots - parallel
dicots - branched

Question 11

distinguish between monocots and dicots plants, by writing a sentence on organisation of vascular bundles in the stem

Answer 11

monocots - random
dicots - in a circle

Question 12

indicate two ways plants use to control transpiration

Answer 12

waxy cuticle
action of stomata

Question 13

give two structural difference between xylem and phloem

Answer 13

xylem - dead, has lignin
phloem - living, has not lignin

Question 14

in which zone is water absorbed from the soil

Answer 14

differentiation

Question 15

name the process through which water is absorbed from the soil

Answer 15

osmosis

Question 16

name the tissue that transports water in roots

Answer 16

xylem

Question 17

describe the mechanism by which water moves through the tissue to the leaves in a plant

Answer 17

water molecules stick together(cohesion)
water molecules stick to side of xylem(adhesion)
water evaporates(transpiration) and pulls water upwards

Question 18

what is meant by the term dicot

Answer 18

seeds have two cotyledon

Question 19

name the part of the microscope you used to bring the section into a sharp focus

Answer 19

fine knob

Question 20

name the vascular tissue through which the products of photosynthesis are transported in plants

Answer 20

phloem

Question 21

give two structural features of the phloem

Answer 21

sieve tubes
sieve plates
