Telophase 1 and Anaphase 1 Concepts

The video tutorial explains telophase 1, focusing on the role of spindle fibers in chromosome movement. It includes a diagram to highlight differences between anaphase 1 and telophase 1. The tutorial describes the formation of haploid daughter cells and compares telophase 1 with mitosis, emphasizing the reappearance of the cell membrane and nucleolus.

What is the primary function of spindle fibers during Anaphase 1?

• To form the cell membrane

• To pull chromosomes towards the poles

• To create the nucleolus

• To divide the cytoplasm

What is a key difference between Anaphase 1 and Telophase 1?

• Chromosomes align at the equator

• Spindle fibers disappear

• Chromosomes are pulled apart

• Cell membrane and nucleolus reappear

During Telophase 1, what structure begins to form as the cytoplasm constricts?

• Cell plate

• Spindle fibers

• Nucleolus

• Furrow

In Telophase 1, what happens to the cell membrane and nucleolus?

• They reappear

• They divide

• They merge

• They disappear

How does the chromosome number in Telophase 1 compare to that in mitosis?

• It is doubled

• It is halved

• It is tripled

• It remains the same

What is the chromosome count in each nucleus after Telophase 1 in human cells?

• 12 chromosomes

• 92 chromosomes

• 23 chromosomes

• 46 chromosomes

What is the result of Telophase 1 in terms of cell type?

• Tetraploid daughter cells

• Haploid daughter cells

• Diploid daughter cells

• Polyploid daughter cells

Which phase is characterized by the reappearance of the cell membrane and nucleolus?

• Prophase

• Metaphase

• Anaphase

• Telophase
