Jiangsu Education Edition Seventh Grade Biology Volume 1

Description

"Plant Cell Structure and Function" PPT

Part One: Classroom Activities

Activity 1: Observation experiment

Observation: Structure of onion scale leaf epidermal cells

Experimental purpose: Identify the basic structure of plant cells

Experimental equipment: microscope, slide, cover slip, tweezers, dropper, onion (outer skin), absorbent paper

Experimental instructions (steps):

1. Make temporary slide specimens

2. Observe

3. Draw a picture

Activity 2: Build a model

DIY: Make a plant cell model

provide materials

Plastic lunch boxes, plastic bags, water, walnuts, balloons.

discuss:

Which cellular structure can each of the five materials provided above represent?

How can they be combined to construct a plant cell model?

Plant cell structure and function PPT, part 2: summary

Good at summarizing and making continuous progress

The life activities of cells rely on the division of labor and cooperation of various structures in cells, and the life activities of plants are based on the various life activities of cells. Therefore, cells are the basic unit of life activities of plants.

After-school DIY small production

Require:

1. Use your imagination and make plant cell models using common materials around you.

2. Attach a piece of paper to write the name of the cell structure represented by each material.

We will organize a competition and the outstanding works will be displayed in the window of the Biology Corner on the second floor of the school.
