27
First root to emerge from seed
Primary roots
28
Primary root enlarges. Can grow to collect water from the deeper part of the soil
Taproot
29
Numerous and are extensively branched. Collect water from a wide area and are excellent for preventing soil erosion
Fibrous roots
30
Hold leaves up to sunlight and transport water and food between roots and leaves
Stem
31
Vascular tissue in stems is arranged in
Vascular bundles
32
Vascular tissue in roots
Central cylinder
33
Have vascular bundles that form a ring that divides the ground tissue into cortex and pith
Dicot stems
34
Have bundles that are scattered throughout the grand tissue
Monocot stems
35
Where leaves are attached at the specific location in the stem
Nodes
36
Trap sunlight for photosynthesis. Store food, protect some plants from animals .
Leaves
37
Structure of leaves
Simple Leaves Compound Leaves The three tissue types Leaf epidermis Stomata Guard Cells Mesophyll Veins
38
Consist of a board flat blade and stemlike petiole
Structure
39

Simple Leaves
40
Have more than one blade (leaflets) per petiole
Compound Leaves
41
The three tissue types
Dermal Ground Vascular tissues
42
Have waxy cuticle and stomata
Leaf epidermis
43
Pores in the epidermis that allows gaseous exchange
Stomata
44
Surround the stomata and regulate the entrance and exit of materials depending on environmental conditions and needs of the plant
Guard cells
45
A region between the two layers of the epidermis
Mesophyll
46
Vascular bundles in leaves
Veins
47
Leaf Type

48
Veins that run parallel to each other
Monocot leaves
49
Can either be pinnate or palmate
Dicot Leaves
50
Feather, with smaller veins branching off a main central vein called midrib
Pinnate leaves
51
Lobed and resemble the fingers and palm of the hand
Palmate leaves
52
Reproductive structure. All blank contain a plant embryo and stored food in a protective seed coat
