TERM 1
Basic Parts of a Plant ROOTS
DEFINITION 1
Roots- Organ that anchors a vascula r plant (in the soil usually),
absorbs minerals and water, and often stores organic material. The
taproot are in most eudicots and gym nosperms with one main
vertical root developed from the em bryonic root. Taproots often
store organic nutrients that the plan t consumes during flower and
fruit production. In seedless vascular plants and m onocots there
are not taproots the embryonic root dies and the formation of the
roots is considered fibrous root system s. Most importantly the
roots is the main source for plants abs orption of water and
minerals.
TERM 2
Examples of Modified Roots
DEFINITION 2
a)prop root b)storage root c)strangling aerial roots d)Buttress
roots e)Pneumatophores
TERM 3
Basic Parts of a Plant STEMS
DEFINITION 3
Stems- Organ consisting of nodes wh ere leaves are attached along
with internodes. The ax illary bud is used to structure formation of
lateral shoot known as branches. Terminal buds are developing
leaves and a compact series of node s and internodes. The
proximity of the terminal bud is partly responsible for inhibiting
growth called apical dominance. This increases the exposure to
sunlight.
TERM 4
Examples of Modified Stems
DEFINITION 4
a)stolons b)bulbs c)tubers d)rhizomes
TERM 5
Basic Parts of a Plant LEAVES
DEFINITION 5
Leaves- organ used for photosynthetic in most vascular
plants consisting of a blade, petiole. Among angiosperms
grasses and other monocots they lack a petiole; instead a
sheath envelopes the stem.

Basic Parts of a Plant ROOTS

Roots- Organ that anchors a vascular plant (in the soil usually), absorbs minerals and water, and often stores organic material. The taproot are in most eudicots and gymnosperms with one main vertical root developed from the embryonic root.

In seedless vascular plants and monocots there are not taproots the embryonic root dies and the formation of the roots is considered fibrous root systems.

TERM 3

Basic Parts of a Plant STEMS

DEFINITION 3 Stems- Organ consisting of nodes where leaves are attached along with internodes. The axillary bud is used to structure formation of lateral shoot known as branches. Terminal buds are developing leaves and a compact series of nodes and internodes. The proximity of the terminal bud is partly responsible for inhibiting growth called apical dominance. This increases the exposure to sunlight. TERM 4

a)stolons b)bulbs c)tubers d)rhizomes

TERM 5

Basic Parts of a Plant LEAVES

DEFINITION 5

Leaves- organ used for photosynthetic in most vascular

plants consisting of a blade, petiole. Among angiosperms

grasses and other monocots they lack a petiole; instead a

sheath envelopes the stem.

Examples of Modified Leaves

a)Tendrils b)spines c)storage d)Bracts e)reproductive

TERM 7

Characteristics of Leaves

DEFINITION 7

Monocots and Eudicots differ in arrangement of veins. Most

monocots have parallel major veins running length of the

blade. Eudicots are more multi-branched network of major

veins.

TERM 8

Characteristics of Leaves SHAPES

DEFINITION 8 a)simple leaf- a simple leave is a single, undivided blade. Some simple leaves are deeply lobed. Consist of a petiole and axillary bud b)compound leaf- in a compound leaf, the blade consists of multiple leaflets. The axillary bud is not formed at the base and consist of a leaflet petiole and axillary bud. c)doubly compound leaf- each leaflet is divided into smaller leaflets and contain the same parts as a compound leaf with doubled leaflets. Also remember the terms whorled, alternate arrangements, opposite arrangement. TERM 9

Characteristics of Plant Tissue DERMAL

DEFINITION 9

Dermal- It is the outer protective covering forming against

defense of physical damage and pathogenic organism

consisting of epidermis and where some woody plants form a

periderm. The cuticle helps prevention of water loss

TERM 10

Characteristics of Plant Tissue VASCULAR

DEFINITION 10

Vascular- The long distance transport of materials that works

with the xylem and phloem starting at the bottom of the stele

where it forms the vascular cylinder along with bundles.
