Plants: Structure And Growth Exam 3

Front 1

three categories of tissue systems in flowering plants?

Back 1

ground, vascular, dermal

Front 2

three basic organs of a plant

Back 2

root, stem, leaves

Front 3

check out diagram of a flowering plant yo

Back 3

got it

Front 4

four types of dermal tissue
-functions

Back 4

1. simple epidermis
-barrier, reduce H20 loss
2. specialized epidermal cells
-guard cells in pairs, stoma for gas exchange and water vapor release
3. root hairs - absorption of H20
4. cuticle

Front 5

ground tissue types
-function

Back 5

1.leaves - photosynthesis
2. other plant part - store water, strucure, store sugar in starch

Front 6

vascular tissue types
-function

Back 6

1.xylem (vessels and tracheids) conduct water and dissolved minerals
2. phloem - (sieve tube members, companion cells) - conducts dissolved sugars from leaves

Front 7

a main vertical root that develops from an embryonic root and gives rise to lateral branch roots

Back 7

taproot

Front 8

root system with no taproot, present in most monocots

Back 8

fibrous root system

Front 9

protects the apical meristem as the root pushes through the soil during the meristem
-also lubricates the soil

Back 9

root cap

Front 10

plant tissue that remains embryonic as long as the plant lives, allowing for indeterminate growth

Back 10

meristem

Front 11

zone of the the root where most of the growth occurs as root cells elongate
-pushes the tip further into the soil

Back 11

zone of elongation

Front 12

zone where cells complete their differentiation and become distinct cell types

Back 12

zone of maturation (differentiation)

Front 13

outermost layer of tissue of root

Back 13

epidermis

Front 14

account for much of the absorption by the root's epidermis by increasing surface of epidermis

Back 14

root hair

Front 15

vascular cylinder consisting of a solid core of xylem and phloem

Back 15

stele

Front 16

3 components of stele

Back 16

xylem, phloem, pericycle

Front 17

outermost layer of vascular cylinder

Back 17

pericycle

Front 18

functions of a stem

Back 18

support for leaves, conduction

Front 19

tissues of the stem

Back 19

epidermis, cortex, vascular bundles, pith

Front 20

functions of a leaf

Back 20

photosynthesis, gas exchange, water transport

Front 21

tissue organization in leaves

Back 21

epidermis - cuticle and stomata
mesophyll - palisade and spongy
vascular tissue - veins

Front 22

a microscopic pore surrounded by guard cells in the epidermis of leaves and stems that allows gas exchange between the environment and the interior of the plant

Back 22

stomata

Front 23

a waxy covering on the surface of stems and leaves that prevents desiccation in terrestrial plants

Back 23

cuticle

Front 24

hairlike outgrowths of the shoot epidermis that provide defenses against insects by forming a barrier or by secreting sticky fluids or toxic compounds

Back 24

trichomes

Front 25

three types of transitional meristem

Back 25

protoderm - epidermis
ground meristem - ground tissue
procambium - cambium

Front 26

adds layers of vascular tissue called secondary xylem and secondary phloem

Back 26

vascular cambium

Front 27

replaces the epidermis with the thicker tougher periderm

Back 27

cork cambium
