PLANTAE
Vocabulary
• Autotroph: An organism that can
make its own food
• Fertilization: Joining of a sperm
and an egg cell
• Phloem: Vascular tubes that carry
food throughout the plant
• Photosynthesis: the process plants
use to produce glucose (food)
for themselves and oxygen
for the air
Vocabulary
• Pollination: the transfer of pollen
from the anther to the stigma in a
flower
• Transpiration: the releasing of
excess water in the form of a gas
from the plants leaves
• Xylem: vascular tubes that
transport water and minerals
throughout the plant
Characteristics
• Multicellular
• Autotrophs or
Producers
______________________
Cell _____
Wall and
• Cells have ____
Chloroplasts
_____________
• Colors can be vibrant to attract
insects and birds for pollination
Structure
A: Leaf
(Fill in Chart)
– Site for photosynthesis
– Called food factories
B: Stem
– Support: for the leaves; used in
transport
– Stores food
• Ex: celery
Structure
(Fill in Chart)
C: Roots
– Anchor: holds plant in soil
– Absorbs: water and minerals
– Some plants store food
• Ex: potatoes, carrots, turnips
Photosynthesis
• Process by which green plants
use carbon dioxide, water, and
light energy from the Sun to
produce glucose (food) and
oxygen
Leaf
• Occurs in the plant’s ______
Photosynthesis
• Provides most of the
atmospheric _____________
Oxygen
O2
• Equation:
Sunlight
6CO2 + 6H2O
C6H12O6 + O2
-------------------
Chlorophyll
• What food do green plants
make? Glucose
• What organelle contains
chlorophyll? Chloroplasts
• What gas in the air is
produced by plants? Oxygen
Transportation
• Phloem-Transports____
Food from
the leaves to the rest of the
plant
• Xylem-Transports Water
____ and
_______________from
the
Dissolved
minerals

Pollination
• _____________transfer of
Pollen from the stamen to the

pistil - How? Wind, insects, birds,
bats, even water
• Fertilization
___________- joining of a
sperm and an egg cell, occurs
after pollination
Flowers
• Once the egg is fertilized, it
develops into a ______
Seed and
the ovary develops into a
______
to protect the seeds
Fruit
•Seeds are dispersed
(Spread) by wind, water,
gravity, and animals
Seeds

•
A Seed Coat :________
protective covering
Food
B-Cotyledon: Stored _______
C-Embryo root
D-First Leaves
Germination – the development of
the seed into a plant
Seeds
• Conifers-seeds are exposed in a
_______
Cone
Flowering plants,
• Angiosperms- _________
Fruit
seeds are protected in a ________
Ecological Succession
• Changes in a community that occurs
over a long period of time
• Going from a state of grasses to a
forest
• Example: Burning of Long Island Pine
Barrens
Review - Motion
• Objects in motion stay in
motion unless acted on by an
outside force
• Friction opposes motion to slow
an object down
• To reduce friction you can add
wheels to an object, make the
surface smooth, or lubricate
(oil, grease, or wax) the
surface
