Slide 1 - Slide

What are we going to learn today?
Today we will learn:
How a new plant originates out of a seed.
What types of plants we can distinguish based on their seeds.
What asexual and artificial reproduction is. 

Slide 2 - Slide

Seeds
Seeds are found in the fruit of the plant. When they germinate, the new plant grows out of the seed. It needs a lot of water and the right temperature to make that happen. 

Slide 3 - Slide

Seeds
Seeds are build out of a some parts. The outside of the seed is called a seed coat. To geminate, a seed needs a lot of food, which it fortunately already has. That food is stored in the cotyledon
There is also a tiny plant already in the seed, which is called the embryo plant

Seeds
We can make two groups of plants based on how the seed is build. Some seeds only have one cotyledon (monocots), and some plants have two (dicots). The plants within those groups also look a lot different. 

Slide 7 - Slide

Monocots vs. dicots
First, study figure 6.63 on page 173. Close your book afterwards. In duo's, you will take turn with drawing and guessing. The person who is drawing, has 20 seconds to draw a characteristic for either a monocot or a dicot. After this, the other person has to guess whether a monocot or dicot is drawn, and explain why they think that. After this you will change the roles.

Asexual reproduction 
Reproducing using flowers is a form of sexual reproduction. You need two sex cells: the egg cell and the pollen. Some plants can also reproduce by just growing, or storing certain parts of the plant. This is called asexual reproduction.
