Exercise 21 Flashcards
Monocots
- one cotyledon
- floral parts in threes
- parallel leaf veins
- vascular bundles spread out
Dicot
- two cotyledons
- floral parts in fours or fives
- netlike leaf veins
- vascular bundles arranged in a ring
Monocot roots
fibrous roots
Dicot roots
Taproot
Tissue Systems
- Dermal
- Vascular
- Ground
Endodermis
control water intake
Guard cells
cells that open and close
Vegetative organs
not associated with sexual reproduction
Morphology
each organ is distinguished by its shape and form
Two large assemblages of flowering plants
dicotyledons (dicots) and monocotyledons (monocots)
Cotyledons
the leaves that are formed within the seed (dicots have two seed leaves, monocots have one)
Root system
the portion usually below ground
What does the plant consist of?
A root system and shoot system
Taproot system
consists of one large primary root, from which lateral roots arise
Nodes
points of attachment
The regions between the nodes
internodes
Axillary bud
give rise to branches and/or flowers
Terminal bud
contains an apical meristem that accounts for increases in length of the shoot system
Simple leaves
each leaf has one undivided blade
The study of a plant’s structure is
morphology
A plant with two seed leaves is
a dicotyledon
A taproot system has
a taproot and lateral roots
What structure is not part of the shoot system
lateral roots
