Biology Chapter 23 Biology Dynamics Of Life

Front 1

What kind of plant cell is most abundant?

Back 1

Parenchyma

Hint 1

Contain Sap

Front 2

Long cells with unevenly thickend cell walls.

Back 2

Collenchyma

Hint 2

Cells are able to grow.

Front 3

At maturity these cells often die; the cell walls are very thick and rigid.

Back 3

Sclerenchyma

Hint 3

Provide support for the plant.

Front 4

Dermal tissue; functions like the skin of an animal.

Back 4

Epidermis

Hint 4

Flattened cells that cover all parts of the plant.

Front 5

What are the openings in leaf tissue that control the exchange of gasses called?

Back 5

Stomata

Hint 5

Found in the epidermal layer.

Front 6

What controls the opening and closing of the stomata?

Back 6

Guard Cells

Front 7

Trichomes

Back 7

Hairlike projections that give a stem or leaf a fuzzy appearance.

Hint 7

Can secrete toxins to protect plants from predators.

Front 8

Xylem

Back 8

Plant tissue composed of tubular cells that transport water and dissolved minerals from the roots to the rest of the plant.

Front 9

Tracheids

Back 9

Tubular cells tapered at each end.

Hint 9

Adjoining cell walls have pits that transfer water and dissolved minerals.

Front 10

Vessel Elements

Back 10

Tubular cells that transport water throughout the plant.

Hint 10

Wider and shorter than Tracheids.

Front 11

Phloem

Back 11

Tubular cells joined end to end.

Hint 11

Similar to xylem.

Front 12

Sieve tube members

Back 12

Contain cytoplasm but do not have a nucleus or ribosomes.

Front 13

Companion cells

Back 13

Nucleated cells that help with the transport of sugars and other organic compounds.

Hint 13

Use sieve tube members from Phloem to perform their function.

Front 14

Ground tissue

Back 14

Composed of parenchyma cells but it may also include collenchyma and sclerenchyma cells.

Hint 14

Found throughout plant cells.

Front 15

Meristems

Back 15

Regions of actively dividing cells.

Hint 15

Differently shaped parenchyma cells with lare nuclei.

Front 16

Apical meristems

Back 16

Found at or near the tips of roots and stems.

Hint 16

Produce cells that allow roots and stems to increase in length.

Front 17

Vascular cambium

Back 17

Produce new xylem and phloem cells in the stems and roots.

Front 18

Cork cambium

Back 18

Produce cells with tough cell walls.

Hint 18

Cover the surface of stems and roots.

Front 19

Endodermis

Back 19

A layer of cells with waterproof cell walls that form a seal around the root's vascular tissues.

Front 20

Pericycle

Back 20

The tissue from which lateral roots aris as offshoots of older roots.

Hint 20

Next to the Endodermis.

Front 21

The tip of each root is covered by a protective layer of parenchyma cells called what?

Back 21

Root cap

Front 22

Sink

Back 22

Any portion of the plant that stores sugars.

Hint 22

Parenchyma has this.

Front 23

Translocation

Back 23

Shows the movement of materials in the vascular tissues of a plant.

Front 24

Petiole

Back 24

The stalk the directly joins the leaves to the stem.

Front 25

Mesophyll

Back 25

Photosynthetic tissue of a leaf.

Front 26

The loss of water through the stomata is called what?

Back 26

Transpiration

Front 27

The tip of each root is covered by a protective layer of parenchyma cells called what?

Back 27

Root cap

Front 28

Sink

Back 28

Any portion of the plant that stores sugars.

Hint 28

Parenchyma has this.

Front 29

Translocation

Back 29

Shows the movement of materials in the vascular tissues of a plant.

Front 30

Petiole

Back 30

The stalk the directly joins the leaves to the stem.

Front 31

Mesophyll

Back 31

Photosynthetic tissue of a leaf.

Front 32

The loss of water through the stomata is called what?

Back 32

Transpiration
