Cell walls of _________________________
Carry out photosynthesis using _________________________
Life cycle
o Gametophyte (_____) > gametes (_____) > fertilization > zygote >
sporophyte (_____) > meiosis > spores (_____) > mitosis > gametophyte
Evolved from _________________________
3 types of tissues
o _________________________ tissue – outer covering
 In leaves covered by _________________________ - waxy layer
o _________________________ tissue – conducts nutrients through plant
 _________________________ - conducts water
 Composed of dead cells called ____________________
and _________________________that act as pipes.
 _________________________ - conducts food
 Composed of _________________________ - contain
openings to allow sugars through
 Also, _________________________ - surround for support
o ________________________ tissue – btw others
 _________________________ - site of most photosynthesis
 ________________________ - flexible walls, help support - celery
 _________________________ - thick, rigid, strong
Structure
o _________________________ – underground organs that absorb water
and minerals, anchors, prevents erosion
 2 types
 ____________________ - one main root – carrots, radishes
 ____________________ - many similar branches
 Structure
 _________________________ - outer layer
o Covered in _________________________ increase surface area for absorption
 _________________________ - middle – ground tissue
 _________________________ - inner
o Aka _________________________
o Contains ________________ & _______________
 Root cap – covers _________________________
o _________________________ - bundles of photosynthetic vascular tissue
 Structure
 ____________________ - flattened section
 ____________________ - attaches to stem
 Specialized ground tissue
o _________________________ - absorbs light
o _________________________ - connects to the
outside via ____________________ (openings) to
allow carbon dioxide in and oxygen out
 _______________ cells – control
opening/closing of ____________________


Functions
 _________________________
 _________________________ - loss of water through
leaves
 _________________________
o _________________________
 3 functions
 Produce ____________________,
____________________, & _______________
 Hold ___________________ up to ___________________
 _____________________ substances between
 Structure
 _________________________ - where leaves attach
 _________________________ - region btw
_________________________
 ______________________ - at ______________________
- tissue that can produce new stems and leaves
 ____________________ growth – occurs in meristematic tissue at
the _________________________ - increase in _______________
 ____________________ growth – increase in _______________
 Occurs in lateral meristematic tissue _______________________ & _____________________
Groups
o _________________________
 Vascular tissue _______________________ – results in small size
 Flagellated _______________ - must stay close to _____________
 No true ____________________ or ____________________
 _________________________ - dominant life cycle
 Ex. ____________________________________________
o _________________________
 Vascular tissue _________________________
 Appearance of true _________________ and _________________
 _________________________ - dominant life cycle
 Ex. _____________________________________________
o _________________________
 Appearance of _________________________ (embryo of a plant
encased in a protective covering with a food supply) which are
produced in _________________________ - plants were able to
reproduce without water
 Male gametophyte - _________________________



Ex. ____________________, ____________________,
____________________
_________________________
 Aka _________________________
o ________________________
 Aka _________________________
 _________________________ - embryonic seed leaves
 _________________________ - 1 seed leaf, parallel veins
o Vascular bundles in stem are __________________
 ______________________ - 2 seed leaves, branched veins
o Vascular bundles in stem are __________________
 May be subdivided based on _______________ characteristics
 _______________ or _______________
 Life spans
 ____________________ - complete a life cycle 1 year
 ____________________ - complete a life cycle in 2 years
 ____________________ - live for more than 2 years
Alternation of Generations
o _______________ (1N) > _______________ (1N) > fertilization > zygote
(2N) > _______________ (2N) > meiosis > _______________ (1N) >
_______________
o Gymnosperms
 Gametophytes are found in ____________________
 __________ cones – male
 __________ cones - female
 _______________ is carried by wind from male to female
o Angiosperms
 Gametophytes are found in ____________________
 Structure
 ____________________ - outermost petals – green –
enclose bud before opening
 ____________________ - brightly colored – attract
pollinators
 ____________________
o ____________________ - thin stalk
o ____________________ - produce male
gametophytes (____________________)
 ____________________
o Aka ____________________
o ____________________ - top – sticky
o ____________________ - stalk
o ____________________ - contains female
gametophytes – becomes ___________________
 Life cycle - _________________________
 ____________________ sticks to ____________________

____________________ forms and grows down style to
ovary
____________________ fertilizes egg = embryo
____________________ joins with other cells to form the
____________________ (food supply)
Seeds
o May be dispersed by ____________________, ____________________,
or ____________________
o May remain ____________________ until conditions are right
o ____________________ - early stage of growth
Plant hormones
o ____________________ - chemical substance that control’s a plant’s
growth, development, and responses
o ____________________ - part affected by a particular hormone
o ____________________ cause:
 ____________________ - growth toward light
 ____________________ - cause branches to grow up and roots to
grow down
 _________________________ - delay the appearance of new
lateral buds (which grow into side branches)
o ____________________ - stimulate cell division, growth of lateral buds,
and sprouting
o ____________________ - promotes overall growth
o ____________________ - stimulates fruits to ripen
Plant responses
o ____________________ - response to an external stiumulus
o Types
 ____________________ - response to gravity
 ____________________ - response to light
 ____________________ - changes in growth in response to touch
 Vines
 ____________________ - response to touch
 Mimosa, venus fly trap
____________________ - timing of seasonal activities
o ____________________ - pigment responsible
o ____________________ - flower when days are short
 Ex. Poinsettias
o ____________________ - flower when days are long
____________________ - period when growth/activity decrease or stop
o Usually during ____________________ for deciduous plants
