6.1 The basics

Aim:

What are the main structures of a plant?

What do we mean by ‘the life cycle of a plant’?

Can you recall the Dutch names for these plant parts?

Watch the video on the next slide and describe the life cycle of a plant in two sentences. You do not need to watch the whole video - it is good for practicing your English listening skills.

HW: Complete 6.1 q1-10

For now:

Cut and paste the cards of

the life cycle of a bean in the right order

Mark the following parts in the last picture: leaf, stem, roots, flower

6.2 Roots

Aim:

    What are roots and what functions do they have?
    Which types of root systems are there?

Why do plant roots have cells with roothairs? look it up on page 152

You can skip page 153!

do not learn!!

Review 6.1 Basics & 6.2 Roots

Practise the concepts in Quizlet for 5 minutes

or

Complete the 6.1&6.2 conceptlist in your notebook or make your own flashcards

! Skip ‘The inside of a root’ p. 153 (xylem, phloem etc)

What have I learnt?

Close your books and answer out loud (or teach your peer/brother/sister):

    What are roots and what functions do they have?
    Which types of root systems are there?

HW: Complete 6.1&6.2 q 1-15

and send a picture of your workbook to [e-mail]

or

complete in Bricks online (q1-5&7)

6.3 Stems

    Aim: What is (the anatomy and) the function of stems?

A daffodil is an example of a woody plant

1. true
2. not true

Tekst

How do herbaceous plants get their strength and stay upright?

1. from woody stems
2. from the sun
3. from the pressure of water
4. from the roots

Heartwood provides support and does not transport water

Sapwood transports water and minerals

Xylem = 'tubes' that transport water and minerals

Phloem = 'tubes' that transport sugars (glucose)

Cambium produces

1. xylem
2. phloem
3. both

Bark of a tree is made of

1. cork
2. phloem and cork
3. xylem
4. sapwood

Annual rings of a tree are made up of

1. sapwood
2. heartwood
3. sapwood and heartwood
4. early (spring) wood and late (summer) wood

The oldest annual rings of a tree are located in the center of a trunk

1. true
2. not true

HW: Complete 20 to 27

and send a picture of your workbook to

00:28

Use this video to answer question 24.1 in your workbook

01:20

Read page 156. What is the name of the structure in the stem that transports food and water?

1. the highway
2. the tube
3. the vascular bundle
4. the stem

01:42

Why is this color change occurring?

1. vascular bundles transport water only
2. vascular bundles transport water and dissolved substances like dye

02:26

The rest of the video is about transpiration throught the leaves. This will be covered in 6.4 The leaves. You can see 'stomata' on page 160.

02:54

Xylem is extension material - you do not need to know this!

You do not have to learn page 155 Transport function of stems

The end of 6.3 - What have you learned about the function of stems?

Garden Cress Experiment

Read the task sheet for the experiment here

What is your hypothesis for this experiment? Write it as: “If [fill in answer to research question], then [fill in result in your experiment that comes with that answer]”. or: I expect .... because ....

00:18

Let's focus on english vocabulary

While watching this video I would like you to write down three new english scientific words that  are new to you. Try to find the meaning by listening to the context of the video. If you are still not sure make sure to ask me for the meaning.

02:51

Write down the three new words and their meaning you have learned by watching this video.

1. in a ring towards the outside
2. in the center

01:57

sucrose and amino acids are products of photosynthesis

02:07

Transport in the xylem is

1. both ways
