Sexual reproduction

This two are that you can find. Some plants and animals can use the two in different moments. 

• Sexual reproduction 

 This is make by meiosis. And need two haploid cells to have the reproduction. The cells that       we need are : Spermatozoid and ovulum. One part of the life cycle of the flower  they need         the pollem (male gametophyte) and the ovulum.

• Meiosis 

  The meiosis is the proces  of  division that make a cell to have the half of the genetic  information and only sexual cells. This are important in reproduction and is n or 1n. their phases are the same of mitosis but two times and in the second no are the interphase.

1. Interphase 
2. Prophase 
3. Metaphase 
4. Anaphase 
5. Telophase
6. Cytosinesis

• The Interphase are the when the Chromosomes duplicate in two.
• In the Prophase the nucleus dissapear.
• In the Metaphase the chromosomes are in the center ready to move to the poles.
• In the Anaphase the chromosomes start to divide and the chromosomes move.
• In the telophase the Cromosomes are in the poles.
• In the Citosinesis is the moment that the cell is divided at this moment the citoplasm is distribuid.

• Haploid Cell 

Haploid  cellls are the  cell that only have the half of chromosomes that a normal cell. This is only in the sexual reproduction and this is n.
