Cell Division

During anaphase, a stage in the cell cycle, 

• the membrane surrounding the nucleus dissolves. 
• the mitochondrion processes nutrients.
• the nucleus repairs damaged strands of DNA.
• paired chromosomes separate at protein structures.

In tomato plants, the pollen cells contain only 12 chromosomes compared to the leaf cells that contain 24 chromosomes. What can be a reason for fewer chromosomes in the pollen cells? 

• The pollen cells undergo faster replication.
• The pollen cells are formed by mitotic division.
• The pollen cells are formed by meiotic division. 
• The pollen cells do not undergo replication.
