Quiz 3

Question 1

Cells

Answer 1

smallest living organism

Question 2

tissue/tissue systems

Answer 2

groups of cells that share a similar function

Question 3

organs (root)

Answer 3

RAM, plant grows down towards water

Question 4

organs (shoot)

Answer 4

SAM, plant grows up towards light

Question 5

apical meristem

Answer 5

clusters of cells at the tips of plant roots and shoots that are responsible for the growth of new organs and the extension of the plant’s body

Question 6

dermal tissues

Answer 6

refers to the plant epidermis, the outer layer of tissue that surrounds the primary body of vascular plants

Question 7

ground tissues

Answer 7

the tissue in a plant that is not vascular or dermal, and makes up the majority of the plant’s body, made up of three types including parenchyma, collenchyma, and sclerenchyma

Question 8

collenchyma

Answer 8

tissue strengthened by the thickening of cell walls, as in young shoots

Question 9

paranchyma

Answer 9

tissues that are formed by living cells with thin cell walls that can carry different functions depending on the needs of the plant

Question 10

sclerenchyma

Answer 10

strengthening tissue in a plant, formed from cells with thickened, typically lignified, walls.

Question 11

vascular tissues

Answer 11

a complex tissue found in plants that transports nutrients and water throughout the plant body and provides mechanical support

Question 12

xylem

Answer 12

moves water from the roots upward to the leaves or shoots to be used in photosynthesis, and also delivers dissolved minerals and growth factors to cells through passive transport

Question 13

phloem

Answer 13

he vascular tissue in plants that conducts sugars and other metabolic products downward from the leaves.

Question 14

Roots

Answer 14

anchor plant to soil, support, medicine, water + nutrients from soil

Question 15

root hairs

Answer 15

increase surface area of roots to improve ability to extract materials from soil

Question 16

stem

Answer 16

support for branches, leaves, and reproductive structures, more water through vessels (xylem, phloem) storage organs

Question 17

modified stem

Answer 17

storage, protection, photosynthesis, support, propagation and perennation

Question 18

rhizome

Answer 18

horizontal, underground (ginger)

Question 19

bulb

Answer 19

large, globe shaped, onion

Question 20

tuber

Answer 20

potato

Question 21

stolon

Answer 21

good at cloning itself, strawberry, horizontal growth above ground

Question 22

leaves

Answer 22

main organ of photosynthesis

Question 23

dicot

Answer 23

2 cotyledon (true wood)

Question 24

monocot

Answer 24

1 cotyledon

Question 25

cotyledon

Answer 25

a seed leaf, or embryonic leaf, that is a key part of a plant’s seed embryo (each half of a bean is one)

Question 26

epidermis

Answer 26

the outermost layer of cells covering the entire plant body, including leaves, stems, roots, flowers, and fruits

Question 27

vascular bundle

Answer 27

monocot, a strand of tube-like tissues in plants that transport essential substances throughout the plant

Question 28

petiole

Answer 28

the stalk that joins a leaf to a stem; leafstalk.

Question 29

blade or lamina

Answer 29

site of photosynthesis

Question 30

leaf margin

Answer 30

the outer edge of a leaf blade

Question 31

bud

Answer 31

new developing tissue, “the bud defines the unit of a leaf”

Question 32

simple leaf

Answer 32

A simple leaf has a single lamina, or blade (rubber tree)

Question 33

compound leaf

Answer 33

A compound leaf has a blade that is divided into multiple leaflets, each with its own small petiole (ivy)
