Tree Biology

Front 1

In the CODIT model, the LEAST effective barrier resists the spread of decay in the tree trunk

Back 1

vertically

Front 2

You can tell the yearly extension growth of a twig by

Back 2

measuring between the terminal and bud scars.

Front 3

Specialized zones of intense cell division in plants are known as

Back 3

Maristems

Front 4

Old phloem becomes incorporated in the

Back 4

bark

Front 5

The closure of a would on the trunk of a tree is accomplished by

Back 5

formation of new-tissues by the cambium.

Front 6

The tree root that are PRIMARILY responsible for holding the tree erect are

Back 6

large basal roots

Front 7

Organic compounds more PRIMARILY away from the leaves and downwrd through the tree in the

Back 7

phloem

Front 8

Tap roots

Back 8

initiate root distribution in the soil.

Front 9

Every branch on a tree

Back 9

has a single corresponding root connected to it.

Front 10

Allelopathy occurs when

Back 10

one plant chemically inhibits the growth of another plant.

Front 11

Phototropism in a plant is

Back 11

a directional response to light.

Front 12

A group of cells which provides shoots and leaves is called the

Back 12

apical meristem

Front 13

Osmosis is the movement of

Back 13

materials across a membrane from areas of high concentrations to areas of low concentrations

Front 14

A true statement about roots is that

Back 14

roots grow when and where the environment is favorable.

Front 15

A FALSE statement about respiration is

Back 15

only green plants are capable of respiration.

Front 16

If the terminal bud is removed by pruning

Back 16

growth from lateral buds will be stimulated.

Front 17

New cells forming on the inside of the cambium become known as

Back 17

Xylem

Front 18

It is a FALSE statement to say that bark

Back 18

transpots water

Front 19

In a cross section of a tree, the line of cells that extend across the annual rings are called

Back 19

rays

Front 20

Tree trunks containing wood decay organisms

Back 20

will usually wall of decaying wood

Front 21

Most water and essential elements are absorbed into the tree through the

Back 21

ends of the root and mycorrhizae

Front 22

Stored food for growth and maintenance of a branch comes PRIMARILY from the

Back 22

last few annual rings of sapwood in the branch.

Front 23

The pard of the root that senses and reacts to the surrounding soil environment

Back 23

The root caps and root meristems

Front 24

The PRIMARY function of heartwood is

Back 24

mechanical support.

Front 25

Trees absorb nearly all water and minerals through

Back 25

fine, fibrous roots.

Front 26

The letters of 'CODIT' stand for

Back 26

compartmentalization of decay in trees.

Front 27

Seasonal changes within the bud are sensed by

Back 27

phytochrome

Front 28

In respiration, sugars utilized to generate energy for a tree produce water and

Back 28

carbon dioxide.

Front 29

Specialized zones of intense cell division in plants are known as

Back 29

meristems

Front 30

A tree uses sugars and oxygen to release carbon dioxide and enerhy in a process known as

Back 30

respiration

Front 31

Gas exchange in the bark is through

Back 31

lenticels

Front 32

When transpirational water losses exceed the tree's ability to take up water from the soil, the IMMEDIATE result is that

Back 32

the stomated close

Front 33

The negative pressure gradient created by transpiration allows

Back 33

water to be pulled up through the tree

Front 34

You can tell the yearly extension growth of a twig by

Back 34

measuring between the terminal bud scars.

Front 35

Tree trunks containing wood decay organisms

Back 35

should be left alone
