ROOT SYSTEM

Question 1

to locate water and minerals, roots permeate the soil. In doing so, they anchor the plant in one place for its entire life.

Answer 1

anchorage

Question 2

roots absorb large amounts of water and dissolved minerals (nitrates, phosphates, and sulfates) from the soil.

Answer 2

absorption

Question 3

the entire mass of underground roots produced by a plant

Answer 3

root system

Question 4

water and minerals upward into the stem and food from leaves to storage regions of roots

Answer 4

conduction

Question 5

roots store large amounts of energy reserves, initialy produced ni the leaves of plants via photosynthesis, and
transported ni the phloem, as sugar, to the roots for storage, usualy as sugar or starch, until they are needed.

Answer 5

storage

Question 6

roots function

Answer 6

anchorage
absorption
conduction
storage
reproduction
photosynthesis

Question 7

first root that comes from a plant

Answer 7

radicle

Question 8

a strongly developed main root which grows downwards bearing lateral roots much smaller than itself.

Answer 8

taproot system

Question 9

has several to many roots of
the same size that develop from the end of the stem, with smaller lateral roots branching off of them.

Answer 9

fibrous root system

Question 10

roots that develop in an unusual place. There are several types of adventitious roots besides those of monocots

Answer 10

adventitious roots

Question 11

These root are thicker in the middle and
tapered on both ends. In this type of roots both hypocotyl and root help in storage of food.

Answer 11

fusiform roots

Question 12

These roots are thicker at their upper side and tapering at basal end.

Answer 12

conical roots

Question 13

These roots become swollen and spherical at upper end and tapered like a thread at their lower end.

Answer 13

napiform

Question 14

formation of adventitious roots, that is, roots that develop in an unusual place

Answer 14

reproduction/propagation

Question 15

erect root that rises up above the soil or water and promotes gas exchange

Answer 15

pneumatophores

Question 16

big roots that look like they arise from the base of the tree trunk provide additional tensile forces to resist uprooting of large tropical trees.

Answer 16

buttress roots

Question 17

Large pillars like roots develop from horizontally spread branches of tree. They grow vertically downward into the soil and support the spreading branches. The main function is mechanical support or pillars

Answer 17

prop/stilt roots

Question 18

these roots arising from nodes attach hemselves to some support and
climb over it

Answer 18

climbing/clinging roots

Question 19

arise from the main stem. These penetrate obliquely down in to the soil and give support to the plant

Answer 19

brace roots

Question 20

They penetrate the tissues of the host and connect to the vascular system, thus becoming part of the host pipelines.

Answer 20

parasitic roots

Question 21

are adventitious parasitic roots

Answer 21

haustorial roots

Question 22

are known from 90 percent of plant species and are a mutualistic association of a fungus with plant root tissue.

Answer 22

mycorrhizal roots

Question 23

spherical structures at the roots of
leguminous plants

Answer 23

nodulea
