Observe plant structures (cambium, guard cells, phloem, xylem, seed, and stomata), organs (roots, stems, leaves, flowers, fruits, cones), and tissues (meristematic, ground, dermal, and vascular) and relate them to physiological processes (photosynthesis, cellular respiration, transpiration, and reproduction).
Essential Question: How have the structures and functions of plants enabled them to survive?

Ground tissues are like:
Vascular tissues are like:
Human Body
Tissue in most plants containing undifferentiated cells (meristematic cells), found in zones of the plant where growth can take place.
1. Compare dermal, ground, and vascular tissues of plants.
2. What is cuticle? What is its role?
3. What are guard cells and stomata?
4. An important concept in biology is that form follows function. In other words, the structure of an organism, or part of an organism, depends on its function. Apply this concept to plants, and explain why plants have different types of cells and tissues
Have you ever seen
a tree “move” a block
of cement on the
sidewalk or push
through a fence?
What does that
suggest about the
roots and stems of a
woody plant?
A. FUNCTIONS OF ROOTS1. Anchor & support
plant in the ground
2. Absorb water &
minerals
3. Hold soil in place
Fibrous RootsRoot Hairs
1. Root Hairs:
increase surface
area for water &
mineral
absorption
2. Meristem:
region where
new cells are
produced
through cell
division.

Xylem
Phloem
A. FUNCTIONS OF STEMS
1.Support system for plant body
2.Transport system carries water & nutrients
3.Holds leaves & branches upright
THE STRUCTURE OF A STEM
Xylem- transports water and
mineral salts from the roots to
the stem and leaves. It also
provides strength to the plant.
Phloem- transports
manufactured food from the
leaves to the roots.
The vascular cambium grows additional xylem
and phloem as the plant grows in thickness.
sugars
phloem xylem
water
Sugars move from their source,
such as photosynthesizing
leaves, into the phloem.
1
The sugars move into the
sink, such as root or fruit,
where the are stored.
3
Water moves from the
xylem into the phloem by
osmosis, due to the higher
concentration of the
sugars in the phloem. The
water flow helps move
sugars through the
phloem.
2
A. FUNCTIONS OF LEAVES1. Main photosynthesizing organ
of the plant.
2. Broad, flat surface increases
surface area for light
absorption.
3. Have systems to prevent
water loss
4. System of gas exchange
Elephant Ear Plant
B. LEAF STRUCTURES
1.Cuticle: waxy layer; covers upper surface Protects leaf against
water loss
2.Veins: transports water, nutrients and food Made of xylem and
phloem
3.Mesophyll: contains cells that perform photosynthesis
b/c they contain Chloroplasts.

Guard Cells
4. Stomata: openings
in leaf’s surface;
when open: • GAS EXCHANGE:
Allows CO2 in & O2
out of leaf
• TRANSPIRATION:
Allows excess H2O
out of leaf
Stoma
1. Transpiration: loss
of excess water from
plant leaves.
-Caused by cohesion and
adhesion in xylem and
by the opening and
closing of stomata!
C. PLANTS FIND A USE FOR TRANSPIRATION
BA
Significance:
a. helps pull water and
nutrients up stem
from roots.
b. part of the water
cycle, trees transpire
water back into the
atmosphere.
c. Helps determines the
balance of water
within the plant.

• Plants reproduce sexually.
• There must be sperm (pollen) and an egg.
• Pollination is when pollen meets the female reproductive parts of the same species.
• Plants can be classified by how they spread their seeds.
• Angiosperms- a seed plant that has seeds enclosed in some type of fruit.
• Ex: Apple plant
• Gymnosperms- a seed plant whose seeds are not enclosed in fruit.
• Ex: pine trees

1. There are 3 types of plant tissue (dermal, vascular and Ground) made from many different types of plant cells.
2. Plants have three main goals:1 absorb and transport materials, 2 turn sunlight into food for the plant, 3 reproduce to make more plants. Different structures that allow them to carry out these different life processes.
3. In order to survive, plants must keep the correct balance of water.
Explain the processes in which plants move materials through their bodies?
