☀️Structure Of Flowering Plant Flashcards
Root functions
Store food
Absorb minerals
Root types
Tap roots
Fiberous roots
Tap roots
Main root thats develops from the redical
Eg of tap root
Carrot
Fiberous root
Equal sized roots arising from the stem base
Eg of fiberous root
Grass
Name the two zones
Zone of protection
Zone of cell production
Zone of elongation
Zone of differentiation
Zone of protection
Protects cells as they push through soil
Zone of cell production
Cells in it are constantly dividing by mitosis to produce new cells for root growth
Meristem
A plant tissue capable of mitosis
What do meristems allow plants to do
Grow
Meristem found..
Stems and leaves
Apical meristem found..
Root tip and shoot tip
Zone of elongation
Plant growth regulators stimulate the cells to grow longer
Zones of differenciation
Develop into the following tissues
Dermal tissue
Vascular tissue
Ground tissue
Dermal tissue
Protects plant
Vascular tissue
Xylem and phloem
Ground tissues
Found between dermal and vascular tissue
Herbaceous plants
Do not contain wood
Woody plants
Contain wood
Node
Point on a stem at which a leaf is attached
Internode
Region on a system between two nodes
Bud
Potential growth
Lenticel
Opening on a stem for gas exchange
Stem function
Supports leaves and flower for height
Transports water and minerals from roots to leaves
Petiole
Stalk of the leave
Sessile
leaves that do not have a petiole
Venation
Patterns of veins on leaves
Parallel ventation
Found in monocots eg grass
Eg of monocotyledons
Grass
Net venation
Veins form a branching netowork
Found in most dicots eg rose
Eg of dicotyledons
Rose
Leaf function
Photosynthesis
Transpiration
Gas exchange
Dermal tissue forms..
Covering layer on a plant
Another word for dermal tissie
Epidermas
Dermal tissue function
Protect
D.T secondary function
Coated with a waxy cuticle to prevent water loss from the plant
Ground tissue function
Photosynthesis
Vascular tissue consists of
Xylem and phloem
Vacular tissue function
Transports materials throughout the body
What are the 2 cells in xylem called
Tracheids and vessels
Xylem vessels
Are more prutine than vessels. They are the only type of xylem found in coniferous trees
Coniferous
Pine
Xylem vessel
Wider than tracheids and their walls break down to form a continuous tube
What is phloem mainly composed of
Sieve tubes and companion cells
Phloem is a..
Loving tissue that transports water
Phloem walls are made of
Cellulose
Location of phloem
Roots
Stems
Leaves
Flowers
Lignin
A strengthening material found in some plant cell walls
Cotyledon
A seed leaf
Flowering plant
Are subdivided into monocots and dicots
Dicot plant
Carrot
