Chapter 22 B Flashcards
What are the two major groups of angiosperms?
monocots and eudicots.
What are five differences between monocots and eudicots? (moncots)
- Number of cotyledons: Monocots have one
- Monocots have parallel veins
- stem vascular tissue scattered in complex arrangement
- Monocots typically have fibrous roots
- Monocots usually have flower parts in multiples of three
What are five differences between monocots and eudicots? (eudicots)
- Number of cotyledons: eudicots have two.
- eudicots have branched veins.
- stem vascular tissue usually arranged in rings
- eudicots have a taproot.
- eudicots usually have flower parts in multiples of four or five.
What are vascular bundles?
a grouping of xylem and phloem
What is pith?
ground tissue inside a ring of vascular bundles
What is cortex?
ground tissue outside a ring of vascular bundles
What are veins?
collection of xylem and phloem
What are fibrous root systems?
branching root system arising from a plants stem.
What are taproot systems?
large central root and is lateral branches
What are vascular cylinders?
Vascular cylinders are the central part of roots and stems that contain the vascular tissues.
What is endodermis?
the innermost cell layer of root cortex
What is pericycle?
produces lateral roots
What is meristem?
where plants undergo growth
What is apical meristem?
helps plants with primary growth
What is lateral meristem?
helps plants with secondary growth
What occurs in the zones of cell division, elongation, and maturation?
In the zone of cell division, new cells are produced
in the zone of elongation, cells undergo growth
in the zone of maturation, cells find their role
What is the function of the root cap?
to protect cell division
What is vascular cambium?
lateral meristem
Which three tissues does vascular cambium produce?
xylem, phloem, and rays
What is wood?
xylem
What is cork cambium?
produces cork cells
What is the function of bark?
outerlayer of a woody plant, protection
What does bark include?
Bark includes the cork, cork cambium, and phloem.
What are heartwood and sapwood?
Heartwood is nonfunctioning secondary xylem
sapwood is functioning secondary xylem
