Structure and Function of Plants Review and
Foldable
2
Fold your sheet in half along the crease line.
3
Cut flaps on folds by cutting the first layer
only.

Structures
Functions
Open your foldable and label it like this.
5
Fill in your foldable with the notes provided.
Structure will go on one side and function will
go on the other. Adaptations to the environment
will go on the back.

Flowers
7
Structure Anther Pollen Stigma Style Ovary

• Function
• -produces pollen
• -haploid male gametes (sex cells)
• -Sticky top of style where pollen lands. The
  Style transports it to the ovary.
  ----------Female organ which produces female
  gametes

8
Adaptation to Environment 1. Bright colors and
sweet nectar to attract pollinators. 2.
Development of Fruit for seed dispersal.

Leaves
10
Structure Upper Epidermis Palisade Layer Spongy
Layer Lower Epidermis

• Function
• -contains cuticle prevents water loss
• Light reactions of photosynthesis.
• Calvin cycle (stores CO2)
• Lets CO2 in and O2 and water out (stomata)

11

• Adaptation to Environment
• Thick cuticle in dry climates.
• Few stomata to prevent water loss.
• Reduced surface area to prevent water loss.
  (Cactus)

12
Stems
13
Structure Xylem Phloem
Function -vascular tissue (tubes) that carry
water from the roots to the leaves for
photosynthesis and to other parts of the
plant. -Vascular tissue (tubes) that carry sugar
from the leaves to other parts of the plant.
14

• Adaptation to the Environment
• Stiff cell walls for trunks and branches. Dead
  Xylem becomes the wood on the inside of tree
  trunks.
• Can be modified to store food. Ex. Tubers
  (potatoes) and Bulbs

15
Roots
16
Structure Epidermis and root cap Root hairs Root
tips (apical meristem)
Function -protection and absorption of water and
minerals. -increase surface area for absorption -
tip of root that is growing into the soil (area
of mitosis).
17

• Adaptation to the Environment
• Can be modified to store starch and sugar.
  (Carrots, Beets, Turnips)
• In dry climates root systems can be extremely
  long to reach water.
