Which words come up
when you think about plants?

Chapter 6: Plants

- structure of plants

- plant lifecycles

- growth and photsynthesis

-pollination

- reproduction

- seed dispersel

- asexual and artificial reproduction

6.1 The basics

root

stem

flower

leaf

fruit

Plants consist of plant cells

Revision plant cell:

cell wall

cell membrane

nucleus

chloroplast

cytoplasm

vacuole

mitochondria

The life cycle of a plant

life cycle of a plant

1. plant grow out of seed

2. root grows bigger 

3. first leaves grow

4. plant grows and develops more roots and leaves

5. plant grows flowers, fruit and new seeds

annual plants: life cycle is one year

annual plants (one year)

biennial plants (two years)

perennial plants (year after year.....)

biennial plants: 

life cycle is two years

perennial plants: year after year...... 

perennial plants (year after year.....)

6.2 Roots

Why do plant have roots?

wild carrot is an example of a plant with:

1. a taproot system
2. fibrous root system

Leek is an example of a plant with:

1. a taproot system
2. a fibrous root system

grass is an example of a plant with:

1. a taproot system
2. a fibrous root system

all these plants
have a:

1. taproot system
2. fibrous root system

Why do plant roots have cells with roothairs? see page 152

Inside a root

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

Use this video to answer exercise 6 in Eduhint

01:20

Read page 156 textbook or part G in Eduhint. 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.

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?

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.

00:33

What needs to be transported in plants?

1. water
2. minerals
3. food products of photosynthesis
4. all are true

00:59

What does phloem transport?

1. glucose
2. water

01:52

Where is are the vascular bundels located in the roots?

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
2. one way only (root to leave)

Photosynthesis

Glucose

carbondioxide

oxygen

Water

sunlight

1. How does pollination work?
   
2. Think 1 minute
   
3. Get ready for the spinner!
4. Answer the question if your name is chosen by the spinner.
