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).

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.

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.
