▶ Student, what do you predict will happen if the roots of a plant are cut?

▶ Student, what link can you make between plant roots and the effects of deforestation?

Plant organs: Root

▶ Student, what do you predict is the function of the stem?

▶ Student, what do you predict will happen to a plant if it’s stem is damaged?

Plant organs: Stem

▶ Student, what do you predict is the role of the leaves?

▶ Student, what do you predict is a reason for why different plants have different size of leaves?

▶ Student, summarize your classmates ideas.

Plant organs: Leaves

▶ Student, can you predict why do plants have flowers?

▶ Student, can you build upon what the previous student said?

▶ Student, how do you predict not having flowers would affect a plant?

▶ Student, summarize what your classmates just mentioned about the role and importance of flowers for a plant.

Plant organs: Flower

Write only what is in red*YOU SHOULD ALREADY HAVE THESE NOTES IN YOUR NOTEBOOK; DAILY HOMEWORK STARTING THIS UNIT IS TO COPY NOTES FROM WEBSITE THE NIGHT BEFORE

A. The Four Plant Organs**Draw the flower and its label on your notebook**

What do you think each of these 4 plant organs DOES for the plant?

Flower: Reproduction

Leaves: Produce Food

Stem: Transport

Roots: Absorb and Anchor

1. Roots

• Absorb nutrients and water

• Anchor the plant

• Store food

• Root hairs increase surface area

A single tap root with hairs

Fibrous Roots

2. Stems• Support the plant

• Connect roots and leaves

• Transport water and minerals up

• Transport glucose and nutrients down

3. Leaves

•Capture as much light energy as possible (this is why leaves are thin and flat)

•Take in CO2

•Make food (glucose) in photosynthesis

4. Flowers

• Reproduction

• Plant Organs– Stem– Leaves– Roots– Flowers

• Plant Tissues– Vascular– Dermal– Ground– Meristematic

Notebook Input Preview

Plant Tissue:• Student, what two tissue are present in the roots

of plants?

• Student, what do you predict is the importance of this tissues?

• Student, what would happen if we cut only the tips of a root?

• Student, can you support or challenge what previous student just said? Why?

• Student where is one of these tissues also found?

• Student, can you predict why this tissue is also found in that location?

Plant Tissue:

• Student, what tissue is found in the leaves of plants?

• Student, what do you predict is the importance of this tissue?

• Student, what can you link this plant tissue to a tissue found in humans? How are they similar?

Plant Tissue:

• Student, what tissue is found in plant stem?

• Student, predict the role of this tissue.

• Student, can you build on what previous student just said?

• Student, make an analogy between this tissue and something else from your daily life.

Plant Tissue:

• Student, why are meristematic tissue found in the root and tip of plants?

• Student, what do you predict would happen if we cut off the tip of a plant?

• Student, make a link between meristematic tissue in a plant and a tissue in the human body.

B. The Four Plant Tissues

•Dermal

•Meristematic

•Vascular

•Ground

Tissue Type

Description Why Does the Plant Need It?

Major Feature(s)

Similar to What in Humans?

Dermal

Meristematic

Vascular

Ground

Draw this table into your notebook:

***Use the information from the following slides to fill-in the table your just drew***

▶ Thick, waxy, tough▶ Protects from damage

and water loss▶ Found on surface of

leaves and stems-called epidermis; waxy covering is the cuticle.

Dermal Tissue

What is this like in humans?

Meristematic Tissue

•Cells continuously divide•Responsible for growth in the plant•Apical meristem at tip of roots protected by root cap•Apical meristem also found at top of stem

Stem cells!These are cells that are no particular body part that can become any body part that is needed.These cells may remain in a non-dividing phase for long periods of time until they are activated by a normal need for more cells to maintain tissues, or by disease, or tissue injury.

What is this like in humans?

▶ A system of hollow tubes, like a pipeline

▶ Transports water and nutrients through roots, stems and leaves

▶ 2 types of vascular tubes:Xylem = waterPhloem = food

Vascular Tissue

What is this like in humans?

Cardiovascular SystemDigestive System

▶Cells that lie between dermal and vascular tissues▶Supports the plant—thick, rigid, structural▶ Storage of sugar in roots

and fruits▶ Site of photosynthesis in

the leaves

Ground Tissue

What is this like in humans?

Fat!

• Plant Organs– Stem– Leaves– Roots– Flowers

• Plant Tissues– Vascular– Dermal– Ground– Meristematic

Notebook Output

• What If…• For each of the following

scenarios, explain in a complete sentence what the consequences would be for the plant.

What if an evil child plucked off all the leaves?

38

What if a beetle eats away at the roots of this plant?

39

What if a clot occurs, blocking the flow of materials in the stem?

▶ The purpose of the Lab Activity is to:◦ Look at REAL roots, stems, and leaves◦ To learn and use new vocabulary about the plant◦Work with your classmates to apply what you

have learned today about these parts, what kinds of tissue they are made of, and what their jobs are in the plant.◦ To have FUN! ☺

LAB STATIONS—30 minutes total

▶ There are 6 Lab Stations– let’s set up our papers now▶ On your own paper…◦ Fold the paper into thirds like in the example◦Write your name at the top right-hand side◦ Label the front sections Station #1, Station #2,

Station #3◦ Label the back sections Station #4, Station #5,

Station #6

LAB STATIONS—30 minutes total

▶ You have 2 minutes at each station to LOOK at the plant part, READ the questions with your team, and TALK to your team.

▶ You have 2 minutes to answer the questions about that part.

▶ You have 1 minute to rotate when time is called and begin the next station.

▶ AFTER stations, I will dismiss groups to pick up their tablets
