Unit 13 Review - Plants
Instructions: Below is a chart of words and their definitions. You may use these for three things:
1. Make flashcards with the definitions and vocabulary
2. Cut out the boxes, shuffle them, spread them out face up, and match the definitions with the
vocabulary words (you may wish to take a picture of them first so you can check your answers)
3. Cut out the boxes, shuffle them, spread them out face down, and play memory (you may wish to
take a picture of them first so you can check your answers)
Botany
Meristem
the scientific study of plants and their
relationships
Have a circulatory system
Most plant
No circulatory system and reproduce
with spores
EX: Moss
areas of rapidly dividing cells
Apical Meristem
occurs at tips of roots/ shoots
Lateral Meristem
increases diameter of stems/ stalks
Cuticle
Monocot Cotyledon (sprout)
waxy protective layer on the surface of
the leaves, shoots, etc.
contains a fat layer called cuticle for
protection from drying out
Carries mainly water with dissolved
nutrients away from the roots.
carries food, ex: sugars, made in the
leaves to the roots.
tissue that is not meristem, epidermal,
vascular used for Photosynthesis,
storage, and support
One cotyledon (sprout)
Dicot Cotyledon (sprout)
Two Cotyledons (sprouts)
Monocot Flowers and structures
Flowers and structures in 3 parts
Dicot Flowers and structures
Flowers and structures in 4-5 parts
Vascular Plants
Non-vascular Plants
Epidermis
Xylem
Phloem
Ground Tissue
Monocot leaves
Veins in leaves are parallel
Dicot leaves
Veins in leaves are net/web-like
Monocot vascular tissue
Vascular tissue in bundles throughout
ground tissue
Vascular tissue arranged in a ring
Dicot Vascular Tissue
Root Cap
Tap Root
Fibrous root
Adventitious Root
Protects apical meristem cells
underneath, as the cap is pushed
through the dirt
main root that is larger and grows
faster than the branch roots
all roots about the same size
Blade
roots that form on any plant part other
than the roots
Wide, flat part of leaf
Simple Leaf
blade is undivided
Compound Leaf
Blade is divided into leaflets
Transpiration
moisture is carried through plants
from roots to stomata (small pores) on
the underside of leaves, where it is
released as vapor to the atmosphere
Promotes cell growth in a specific
direction. Makes cells on dark side of
plant grow to push it towards the light
regulate growth
influence various developmental
processes, including stem elongation,
germination, dormancy, flowering, sex
expression, and leaf and fruit
development
promotes cell division (cytokinesis),
thus making plants bigger. Growth of
new shoots
Stimulates seed germination
(sprouting)
Auxin
Gibberellins
Cytokinins
Ethylene
Phototropism
Gravitropism
Thigmotropism
Stamen
Anther
Filament
Pistil
Stigma
Style
Ovary
Ovule
Cross Pollination
Only hormone found as a gas
causes complex carbohydrates to
break down into simple sugars, thus
speeds up ripening
growth toward a light source
growth towards gravity or away from
gravity.
growth towards point of contact.
Male reproductive organ with 2 parts:
Anther and Filament
Where meiosis occurs to produce
pollen
a stalk that supports the anther
Female reproductive organ with 3
parts: stigma, style, and ovary
receives the pollen from the anther
Supports the stigma and the pollen
grows a tube down through this
Contains ovules and becomes the fruit
after fertilization
The unfertilized seeds
Dicot roots
Pollen is received from a different
plant
Taproot system
Monocot roots
Fibrous root system
Stoma
Openings on the underside of the leaf
that allow gas exchange
