1. Plants Part 1: Introduction to Organs, Tissues and Processes

2. A. The Four Plant Organs **Draw the flower and its label on your notebook**
Flower: Reproduction
What do you think each of these 4 plant organs DOES for the plant?
Leaves: Produce Food
Stem: Transport
Roots: Absorb and Anchor

3. 1. Roots Absorb nutrients and water Anchor the plant Store food
Root hairs increase surface area
A single tap
root with hairs
Fibrous
Roots

5. 2. Stems Support the plant Connect roots and leaves
Transport water and minerals up
Transport glucose and nutrients down

6. 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

7. 4. Flowers
Reproduction

8. table should be in your notebook:
Tissue Type
Description
Why Does the Plant Need It?
Major Feature(s)
Similar to What in Humans?
Dermal
Meristematic
Vascular
Ground

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

10. Dermal Tissue Thick, waxy, tough Protects from damage and water loss
Found on surface of leaves and stems-called epidermis; waxy covering is the cuticle.

11. 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

12. Vascular Tissue A system of hollow tubes, like a pipeline
Transports water and nutrients through roots, stems and leaves
2 types of vascular tubes: Xylem = water Phloem = food

13. What is this like in humans?
Digestive System
Cardiovascular System

14. Ground Tissue 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
