This chapter

Small test: report on research on plants (1x)

Big test: test in the test week (3x)

From now on..

No more PIF words! :)

You may ask the Dutch translation but you don't have to study them!

Learning objectives

• You can name the parts of a plant and their function.

• You can name the parts of a plant cell and name the most important functions.

• You can explain how plants stay upright.

• You can describe how water is transported in the plant.

• You can explain how trees lose their leaves and why.

• You can explain why flowers and fruits get their colour.

What part of a bean plant do you eat?

1. Flower and leaf
2. Stem
3. Fruit and seed
4. Roots

Hyacinths and pansies

1.What are the characteristics of the flower, leaf and stem?

2.Which part of the plant is not visible in the pictures?

Organs

• Roots = absorption of water and minerals (nutritional salts) from the soil.
  
• Stem = transport of water and nutrients
  
• Leaves = making nutrients
  
• Flower = reproduction

Details 

Cell = smallest building block of plants

Tissue = a group of cells with the same shape and function

Plant cell

• Cell wall = solid (stevige) layer
  
• Cell membrane = regulates what substances enter and leave the cell
  
• Cytoplasm = viscous (stroperige) fluid
  
• Cell nucleus = control center of the cell
  
• Vacuole = Vesicle with water for firmness/turgidity (stevigheid)
• Leafy green granules = Green structures that make nutrients.

How do plants keep upright?

Herbaceous plants: need water for firmness.

Woody plants: have ligneous cells (houtcellen) for strength; continue to grow. 

Lignin = houtstof

What?	Make 5.1: assignments 3-12
How?	In your workbook (or computer). Use the information from your textbook.
Help?	You may gently consult with your neighbor. Raise your hand if the two of you can't figure it out.
Time?	10 minutes
Finished?	Make a diagram of the parts of the plant cell like the one on the next slide (but in English!).
Product	You have practiced 5.1.

Let's discuss the lesson!
