M5: ROOTS AND PROCESSES Flashcards
stem, roots, leaves
VEGETATIVE ROOTS
non reproductive roots
VEGETATIVE ROOTS
flowers, fruit seeds
REPRODUCTIVE
Anchorage of the plant in soil
ROOTS
Absorbs of waters and minerals
ROOTS
the _____ transports the WATER UPWARD to the shoot
XYLEM
CONDUCTION of water and minerals upward to the stem
ROOTS
REPRODUCTION in the form of PLANT PROPAGATION
ROOTS
how does reproduction takes place in roots
BY PLANT PROPAGATION
STORAGE of food
ROOTS
embryo’s FIRST ROOT
RADICLE
the radicle emerge from the seed through ______
MICROPYLE
located above the radicle
HYPOCOTYL
embryonic stem
HYPOCOTYL
the first leaf
COTYLEDON
supports the cotyledon
HYPOCOTYL
where the SHOOT emerge
PLUMULE
embyronic shoot
PLUMULE
SMALL PORES in the hilum
MICROPYLE
seed scar
HILUM
embryonic shoot ABOVE the COTYLEDON
EPICOTYL
thick MAIN ROOT in the MIDDLE
TAP ROOT SYSTEM
thin, WEB-LIKE
FIBROUS ROOT SYSTEM
Found in DICOT plants
TAP ROOT
- Anchors plant DEEPLY
- Preventing the wind blowing them over
- Food storage
- DROUGHT TOLERANCE
TAP ROOT SYSTEM
single, large taproot EXTENDING FROM STEM
SWOLLEN
LARGER THAN THE AVERAGE ROOT going deeper into the soil
PRIMARY
number of large EQUAL-SIZED taproots
EVEN
mostly found in MONOCOT plants
FIBROUS ROOT SYSTEM
The secondary roots continue to grow & eventually all the roots are of EQUAL OR NEARLY EQUAL SIZE
FIBROUS ROOT SYSTEM
- Absorbs water and nutrients QUICKLY
- Helps prevent SOIL EROSION as they anchor plants to the top layers of soil
FIBROUS ROOT SYSTEM
Main root is used for human and animal consumption
TAP ROOT SYSTEM
Root growth begins with _________
SEED GERMINATION
PRIMARY root growth is controlled by ___________
APICAL MERISTEM
SECONDARY growth is controlled by _________
LATERAL MERISTEM
1st root, embryo
PRIMARY ROOT
from primary
SECONDARY ROOT
various direction
- Anchorage of plants
TERTIARY ROOT
External Structure of a Root
PRIMARY
SECONDARY
TERTIARY
THIMBLE-SHAPE
- protects the growing ROOT TIPS
ROOT CAP
meristematic region
REGION OF CELL DIVISION
root, lengthening
REGION/AREA OF ELONGATION
fully develop and become ADULT CELL
REGION/AREA OF MATURATION
TISSUE of root cap
CALYPTROGEN
○ parenchymal cells
○ GIVE RISE to root cap
CALYPTROGEN
slimy, produce to grow smoothly
MUCILAGE
growth towards sunlight
GRAVITROPISM
statoliths, gravity sensors
AMYLOPLAST
cells divide once or twice per day
APICAL MERISTEM
3 meristematic areas
PROTDERM
GROUND MERISTEM
PROCAMBIUM
forms EPIDERMIS
PROTODERM
forms GROUND TISSUES
GROUND MERISTEM
forms VASCULAR TISSUES
PROCAMBIUM
