ROOTS Flashcards
- ANCHORAGE of the plant in the soil
- conduction of water and minerals upward to the stem
- reproduction in the form of PLANT PROGPAGATION
- absorption of water
ROOTS
Roots function as reproduction in the form of
PLANT PROPAGATION
TWO MAIN TYPES OF ROOT SYSTEMS
FIBROUS ROOT SYSTEM
TAP ROOT SYSTEM
a type of root system that is often found in MONOCOT plants
FIBROUS ROOT SYSTEM
it refers to the fact that most members of this group have ONE COTYLEDON
FIBROUS ROOT SYSTEM
a type of root system that is often found in DICOT plants
TAP ROOT SYSTEM
any member of the FLOWERING PLANTS, or angiosperms, that has a PAIR OF leaves, or COTYLDEONS, in the embryo of the seed
TAP ROOT SYSTEM
FOUR REGIONS OF A TYPICAL ROOT TIP
ROOT CAP
MERISMATIC REGION
REGION OF ELONGATION
REGION OF MATURATION
- THIMBLE-SHAPED cell mass that PROTECTS THE GROWING ROOT TIP by COVERING THE APEX of the root.
ROOT CAP
the root cap covers the ____ of the root
APEX
the location of CELL DIVISION
MERISTEMATIC REGION
is the area of ROOT LENGTHENING. The cell produced from the meristematic region grows in the _______.
REGION OF ELONGATION
this is where the cells that grew in the elongation region FULLY DEVELOPS AND BECOMES ADULT CELLS.
REGION OF MATURATION
EXTERNAL STRUCTURE OF ROOT
PRIMARY ROOT
SECONDARY ROOT
TERTIARY ROOT
– the FIRST ROOT of a plant, originating in the embryo
RADICLE
the first root of the plant is originating in the ____
EMBRYO
produced on the primary root
SECONDARY ROOT
grow in VARIOUS DIRECTIONS and help in FIXING THE PLANT FIRMLY into the soil.
TERTIARY ROOTS
INTERNAL STRUCTURE OF ROOT:
EPIDERMIS
CORTEX
ENDODERMIS
VASCULAR CYLINDER
is the OUTERMOST LAYER that absorbs water and dissolved material from the soil and PROTECTS THE INNER TISSUES OF THE ROOT.
EPIDERMIS
found inside the epidermis, which is COMPOSED OF PARENCHYMA CELLS with large intercellular spaces, secretory cells, resin ducts, and endodermis.
CORTEX
cortex is found inside the ___
EPIDERMIS
is the INNERMOST CELL LAYER that REGULATES ION MOVEMENT into the xylem. The Casparian strip embedded in the cell wall inhibits mineral movement through the wall
ENDODERMIS
The _____ embedded in the cell wall INHIBITS MINERAL MOVEMENT
through the wall
CASPARIAN STRIP
is the INNMEROST LAYER WITH THE XYLEM AND PHLOEM cells for the conduction of materials, parenchyma cells for food storage and support of the other
tissues
VASCULAR CYLINDER
for FOOD STORAGE and support of the other tissues
PARENCHYMA CELLS
for the CONDUCTON OF MINERALS
XYLEM
ARISE ALONG THE STEM or locations OTHER THAN THE BASE OF THE PLANT
ADVENTITIOUS ROOTS
roots that EXTEND OUT INTO THE AIR, unconnected to the ground
AERIAL ROOTS
located on the LOWER PART OF THE STEM of some monocots like corn, GROW DOWN INTO THE GROUND, anchor against the wind
PROP ROOTS
SPONGY OUTGROWTHS from UNDERWATER ROOTS, may extend above water, increase ease oxygen supply to roots
PNEUMATOPHORES
PENETRATE HOST PLANTS to parasitize them
PARASITIC ROOTS
branch roots of plants like sweet potatoes PRODUCE EXTRA PARENCHYMA CELLS for carbohydrate storage
STORAGE ROOTS
produced by certain varieties of fig and tropical trees for SUPPORT.
BUTTRESS ROOTS
tall annual cereal grass
CORN
Zea mays
Poaceae
Boost immune system, SOOTHE ACIDITY
CALAMANSI
Citrus microcarpa
Rutaceae
common name of calamansi
CALAMONDIN
roughly OVAL in shape,
with UNEVEN SIDES
MANGO
Mangifera indica
Anacardiaceae
FLESHY EDIBLE, colorful
roots
CARROTS
Daucus carota
Apiaceae
has anti-cancer, anti-diabetes, and anti-inflammatory
CAMOTE
Ipomea batatas
Convulvulaceae
common name of camote
SWEET POTATO
edible dry seeds
MONGGO
Phaseolus vulgaris
Fabaceae
common name of monggo
COMMON BEAN
branched, fleshy, annual herb, about 1 meter high. Stems are PURPLISH and 4-angled
MAYANA
Coleus blumei
Lamiacaee
represent descending axes of plants which are devoid of leaves
ROOTS
are roots which are SWOLLEN FOR FOOD STORAGE and which show different internal structure from true roots.
TUBEROUS ROOTS
are short, thick, solid, underground stems BORNE USUALLY AT THE END OF SLENDER CREEPING BRANCHES (STOLONS) which arise from the lower region of the aerial stem.
TUBERS
are creeping underground stems of horizontal, VERTICAL OR OBLIQUE GROWTH
RHIZOMES
are short, vertical, underground stems covered with NUMEROUS FLESHY SCALES which comprise the greater bulk
BULBS
are thickened, solid, erect, generally subspherical, underground stems with LEAF SCARS IN THE UPPER SURFACE and ROOT SCARS IN THE LOWER SURFACE.
CORMS
A region of MITOTICALLY INACTIVE CELL called the ___________ is present in the meristematic region.
QUIESCENT CENTER
