Making exercises paragraph 5.1

Slide 1 - Slide

Who am I?
Marijn Durinck
26 years old, 198cm tall
Hiking, exploring nature 
Playing music (guitar, bass, piano)
Playing games 

Slide 2 - Slide

''Why do we need to learn this?''
Discovering what bring you joy/what you're good at
Influence on your curriculum
Knowledge to understand the world around you (now or later). 
Fun and safe time 

Slide 3 - Slide

What do I expect from you?
I can't reach these goals on my own so I expect you to:
Bring your book and notebook
Make homework
Start of the lesson 
Quiet during explanation (fingers)
Phones

Slide 4 - Slide

Who are you?
I will check the presence by calling out everyone's name. When you hear your name, please stand up, introduce yourself and answer the following questions (rest of the group is quiet):
Which day of the holiday would you like to repeat?
What is the most delicious thing you have eaten this holiday?

Slide 5 - Slide

What are we going to learn today?
Today we will be learning:
How the genetic material in a cell is build up. 
What a genotype and phenotype is. 
What the difference is between these two is. 


Slide 6 - Slide

Cell -> DNA
A human body cell has a nucleus where the genetic material is stored. This genetic material is organized through 46 strings, called chromosomes. These chromosomes consist of DNA. All this genetic material is called you genotype.

Slide 7 - Slide

Fertilization and cell division
Sex cells (sperm and egg cells) have 23 chromosomes. During fertilization these two will merge together so an new body cell of 46 chromosomes is made. Then a cell divides and creates new body cells (embryo). 

Slide 8 - Slide

How your genotype is determined

Slide 9 - Slide

Amount of chromosomes in other species

Slide 10 - Slide

Your phenotype
Your appearance is called your phenotype. This is partly determined by your genotype, but not entirely. You can dye your hair, put on make up or undergo plastic surgery. This changes your phenotype, but not your genotype. 

Slide 11 - Slide

Your phenotype changes

Slide 12 - Slide

Get to work
Start with the exercises of paragraph 5.1, which includes exercise 5. This will be homework for the next lesson. 

Slide 13 - Slide

Has the genotype of phenotype changed?

Slide 14 - Open question

Someone got skin cancer for lying in the sun for too long. Has the genotype or phenotype changed?

Slide 15 - Open question

A pollen (sex cell) of a tree has 64 chromosomes. How many chromosomes do the body cells have?

Slide 16 - Open question

What changes throughout your life?
A
Phenotype
B
Genotype
