Science: Order And Reality, 2.8 Transport System

Front 1

stems

Back 1

supports the leaves and flowers of a plant; also used for transporting substances and for storing food

Front 2

woody plants

Back 2

plants that live several years and develop a large amount of wood in their stems

Front 3

herbaceous plants, herbs

Back 3

non-woody plants

Front 4

vines

Back 4

any plant with a long, thin stem that grows along the ground or has tendrils that twine around a wall or other support

Front 5

taproot system

Back 5

the primary root grows straight downs and remains larger than the secondary rootlets

Front 6

fibrous root system

Back 6

the primary root remains small and man slender secondary rootlets grow from it

Front 7

vegetative reproduction

Back 7

plant reproduction without flowers, seeds, or fruits'

Front 8

root cap

Back 8

the tip of the root which is made up of several layers of dead cells and new growth cells that form immediately behind the cap

Front 9

cambium

Back 9

a woody dicot has a layer of cells between its transport tubes

Front 10

cambium cells

Back 10

carry on cell division and make it possible for the root to grow in diameter

Front 11

primary growth

Back 11

growth in length

Front 12

secondary growth

Back 12

growth in diameter

Front 13

root hairs

Back 13

tiny hairs which develop from the sides of the root and forces their way between soil particles to absorb water and dissolved minerals

Front 14

osmosis

Back 14

the continuous movement of water from a solution of higher water content through a semipermeable membrane into a solution of lower water content

Front 15

semipermeable membrane

Back 15

a membrane that will allow some molecules to pass through but not others

Front 16

cortex

Back 16

the inner portion of the root which consists of storage cells surrounding the root's transport system

Front 17

xylem tissue

Back 17

carries water and nutrients from the root hairs upward through the root hairs upward through the root and stem to the leaves

Front 18

the two types of vascular tissue which the plant's transport system consists of

Back 18

xylem tissue and phloem tissue

Front 19

phloem

Back 19

carries glucose from the leaves back to the stem and roots

Front 20

aids the rise of water through the xylem

Back 20

capillary action and root pressure

Front 21

root pressure

Back 21

the upward force that results as water enters the roots by osmosis

Front 22

capillary action

Back 22

the tendency of water molecules to move up through the xylem tissue in response to surface tension

Front 23

transpiration

Back 23

evaporation from the leaves
