Welcome!
Today's lesson:
Introduction
Why biology?
Heredity and evolution
Discussing phenotype and genotype (paragraph 5.1)
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?
