1. Bellringer: Is It a Plant? (10 minutes)
How do you DECIDE what makes a plant a plant? Examples: If it has a ________, I know it’s a plant. If it does__________, I know it’s a plant.
STATE which are plants and which are NOT, then EXPLAIN HOW YOU KNOW. Give EVIDENCE for your statements.

2. What Defines a Plant?
Topic 10: An Overview and Classification of Plants
EDGENUITY HOMEWORK: due next class!

3. All Plants Share What Characteristics?
Eukaryotic
Multicellular
Autotrophic (photosynthetic)
Stationary
Cell walls made of cellulose

4. The Body Parts of a Plant (called ORGANS just like in us!)
What do you think each of these 4 plant organs DOES for the plant?

7. Roots The three functions of roots are
Magnified Root Hairs (increase surface area for absorption)
A single tap
root with hairs
Fibrous Roots
The three functions of roots are
absorb dissolved nutrients and water from the soil
anchor the plant
store food
The root cap is the place where the roots are GROWING!

8. Stems The 4 functions of stems are to support the plant
connect the roots and the leaves
transport water and minerals UP the stem
transport glucose and other nutrients that the plant makes DOWN to the roots for storage.

9. Leaves The major functions of the leaf are:
capture as much light energy as possible
take in CO2 /release O2
to make food (glucose) in photosynthesis.
Transpiration

10. 4 Plant Tissues Tissue Type Description Major Feature(s) Dermal
Why Does the Plant Need It?
Major Feature(s)
Similar to What in Humans?
Dermal
Meristematic
Vascular
Ground

11. 4 Plant Tissues Dermal Meristematic Vascular Ground
Dermal tissue – light blue
Ground tissue – yellow
Vascular tissue - purple
Dermal
Meristematic
Vascular
Ground

12. 1. Dermal Tissue Thick, waxy, tough
Protects the outside of the plant from damage and protects it from water loss
Found on the surface of leaves and stems- called the epidermis; waxy covering is the cuticle.

13. What is this like in humans?

14. 2. Meristematic Tissue
A plant continues to GROW as long as it lives because plants have meristems, the only cells that continually divide, generating new cells.
One example of a meristem is a Root meristem, located at the tips of the roots, and the apical meristem in the buds of shoots, provides elongation of the plant down into the soil and up into the air (growth). Growth in length of roots is concentrated near the root’s tip. The root tip is protected by a root cap, which secretes a substance that helps digest the earth as the root tip grows through the soil.

15. Three Types of Meristem Tissue

16. What is this like in humans?
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.

17. 3. Vascular Tissue A system of hollow tubes, like a pipeline
Purple
A system of hollow tubes, like a pipeline
Transports water and nutrients through roots, stems and leaves and glucose throughout the plant
2 types of vascular tubes: Xylem= water (transpiration) Phloem= food

18. Vascular Cambium is meristem (cells that divide) that makes the vascular tissue of the plant: Xylem (water transport) and Phloem (sugar transport)

19. What is this like in humans?

20. 4. Ground Tissue Cells that lie between dermal and vascular tissues
YELLOW
Cells that lie between dermal and vascular tissues
Storage of sugar in roots and fruits
Supports the plant— thick, rigid, structural
Site of photosynthesis in the leaves (parenchyma)

22. What is this like in humans?
Adipose tissue stores fat

23. LAB STATIONS—35 minutes total
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.

24. LAB STATIONS—35 minutes total
There are 7 Lab Stations
You have 3-4 minutes at each station to LOOK at the plant part and to answer the questions about that part.
You have 1 minute to rotate and begin the next station.
If you do not finish you will have to come in at lunch or after school to finish!
