Mitosis

What are the type of cells created through mitosis?

Body cells/Diploid cells

What are haploid cells?

Cells that are genetically different with only 23 chromosomes

What are diploid cells?

Cells that are the same genetically with 46 chromosomes

Which statement best describes prophase? The cell grows and dna is replicated. Chromosomes condense and spindle fibers form. .Chromosomes line up in the middle of the cell. The. cytoplasm splits and divides into two cells.

Chromosomes condense and spindle fibers form.

How is prophase 1 unique? Homologous pairs join in the middle of the cell Two daughter cells divide into four New nuclei begin to form around chromosomes Chromosomes crossover and exchange genetic information

Chromosomes crossover and exchange genetic information

What happens during metaphase? The cell grows and dna is replicated Chromosomes condense and spindle fibers form Chromosomes line up in the center and spindle fibers attach to the chromosomes The cytoplasm splits and divides into two cells

Chromosomes line up in the center and spindle fibers attach to the chromosomes

What would happen to skin cells if mitosis did not take place? Skin cells would regrow from other types of cells. Skin cells would be replaced at a slower rate. Skin cells would be replaced with new cells. Skin cells would die and not be replaced.

Skin cells would die and not be replaced.

If pink (P) is dominant to white (p) in flowers, what is the genotype of a white flower?

pp

In this phase a nuclear membrane begins to form around the two daughter nuclei and the chromosomes begin to decondense. cytokinesis interphase anaphase telophase

telophase

In which of these stages is mitosis most important? A tiger cub is born. A tiger cub learns to walk. A tiger cub begins to grow. A tiger cub play-fights.

A tiger cub begins to grow.

In this phase the sister chromotides get pulled away from each other to seperate sides of the cell. Interphase Cytokinesis Anaphase Telophase

Anaphase

Which statement accurately describes the relationship between cytokinesis and mitosis? Mitosis includes interphase and cytokinesis. Cytokinesis occurs before mitosis. Cytokinesis occurs after mitosis. Interphase includes cytokinesis and mitosis.

Cytokinesis occurs after mitosis.

What types of cells are created through meiosis?

Gametes, reproductive cells, sperm and egg cells

What happens during interphase? The cell divides for the last time Chromotine condenses into chromosomes The cell grows and duplicates its DNA The chromosomes cross over each other

The cell grows and duplicates its DNA

An example of mitosis at work is a plant root elongating. absorbing. pointing down. breaking.

elongating

Which best describes the importance of mitosis to living organisms? genetic variation and growth growth and development development and sexual reproduction sexual reproduction and genetic variation

growth and development
