Samuel 10/5 - Mind Map of the new terms
Organisms
Multicellular organisms
Chicken and human
Internal fertilization
Sexual reproduction
Mitosis
Bacteria
Asexual reproduction
Single-celled organism
Flowers
Coral
In the ocean
Have more than one cell
Single-celled organisms
Consist of only one cell
Body cell
Each contrasts from the another due to the different amount of proteins it creates
Gamete
Ovum/egg
The final result of mitosis
It makes it harder for the sperm to "come in"
Sperm
It moves itself
Processes
Sexual Reproduction
Unique Offspring
Asexual Reprodustion
Doesn't need another organism
Identical cell is produced
Mitosis
"Performed" by body cells
Cellular Differantiation
The idea that every protein has something to do while in the organism
Gametogenesis
The process of creation of sex cells
Meiosis
Crossing over can be observed
Stages of meiosis
Cytokynesis
The formation of eggs is called Oogenesis
The creation of sperm is called Spermatogenesis
4 cells with 23 chromosomes are made
Prophase 1
Condensed chromosomes
Crossing over
Interphase
the whole DNA is reproduced
Metaphase 1
The chromosomes are located in the middle
Anaphase 1
The homologous chromosomes direct to converse poles
Telophase 1
2 new cells with 23 chromosomes develop
Prophase and Metaphase 2
Chromosomes direct towards the middle and liquefy
Anaphase 2
Chromosomes move apart
Telophase 2
2 new cells with 46 chromosomes form
Male Reproductive System
Testes
The sperm and testosterone is formed there
It is stored in the epididymis
The sperm afterwards goes to the vas deferens; this happens during ejaculation
Fluids are added in the prostate gland
They go out of a man's body firstly through the penis and then the urethra
External fertilization
Fertilization
Internal fertilization
Gametes "meet" inside an organism
Sperm and ovum/egg produce zygote
Sperm and egg "see" each other outside an organism
Types of cells
Prokaryotic
Don't have nucleus
Are Bacterias
Eukaryotic
Contain nucleus and membrane-bound organelles + mitochondria
Are flowers and animals
Female Reproductive System
Zygote
it's a fertilized egg
Ovary
the place where the egg grows
Afterwards, the egg goes to the fallopian tube because of the process of ovulation
Then, it goes to the uterus
It settles into the uterine lining for about 9 months
The fetus "visits" the vagina to grow there
Diploid
It's a cell that has crossed chromosomes. To be more specific, it has 23 pairs of them.
