SNC2D1 – Biology E. Wong (Updated Jan 2018)

Name: __________________________ Period: ______ Date: __________________Lesson 8 Plant Tissues & Organs Activity

Learning Goals:

I can explain what specialized cells do and how they are related to plant tissues.

I can use appropriate biology terminology related to stem cells and plant tissues.

Use your textbook pg. 58 to 67 and flower handout to answer the following questions:Station 1: Specialized Cells and Tissues (Textbook pg. 58 – 59)Meristematic cell:1. What are meristematic cells or meristems?

2. What is/are the function(s) of this tissue?

Dermal Tissue:3. What are the general functions of this tissue?

4. Give some specific examples of this tissue and their specific functions.

Ground Tissue:5. What are the general functions of this tissue?

6. Give some specific examples of this tissue and their specific functions.

Vascular Tissue:7. What are the general functions of this tissue?

Transport of Water in Plants (ON Science 10 p.70-75)Learning Goals:

A. I can explain the transport systems in plants.

The Sun causes water to evaporate

SNC2D1 – Biology E. Wong (Updated Jan 2018)

Transpiration (evaporation of water) from leaves creates tension that pulls water up the xylem from the root.

xylem

stoma

xylem

Cohesion: holds water molecules togetherAdhesion: water molecules stick to the wall of xylem vessel

Stored as starch

H2O + dissolved minerals

light

sugar

dissolved sugar

xylem

soil

root hair

Osmosis: high concentration of mineral helps diffusion of water into xylem
