Unit 6 Mitosis & Meiosis TEST

How is the number of chromosomes in a human sex cell different from the number in a human body cell? 

• A sex cell has 23 chromosomes and a body cell has 46. 
• A sex cell has 46 chromosomes and a body cell has 23.
• A sex cell has chromosomes that are half
• A sex cell has chromosomes that are twice as long as those in a body cell. 

Dante wants to match the types of cells with how they are produced. Which choice correctly matches a type of cell with how it is produced? 

• Egg cell --> meiosis in males 
• Sperm cell --> mitosis in males
• Body cell --> mitosis in females
• Body cell --> meiosis in females

How is meiosis related to sexual reproduction?

• Meiosis allows the offspring produced during sexual reproduction to grow and develop.
• Meiosis joins together the sex cells during sexual reproduction to produce new offspring
• Meiosis produces the sex cells that join to form new offspring during fertilization.
• Meiosis produces the body cells that join to form new offspring during fertilization. 

Which of these choices is made from the process of mitosis?

• Egg
• Sperm
• Sex Cell
• Skin Cell

Which of these choices is NOT a reason for mitosis taking place in a multi-cellular organism? 

• Growth
• Repairing Wounds
• Asexual Reproduction
• Making Sex Cells

During a lab experiment, Rahul looks at six unlabeled slides showing different stages of the cell cycle. The teacher asks Rahul to place the slides in order, starting with Interphase. In what order should Rahul place the slides? 

• Interphase --> prophase --> anaphase --> metaphase --> telophase 
• Interphase --> anaphase --> metaphase --> prophase --> telophase 
• Interphase --> telophase --> anaphase --> metaphase --> prophase
• Interphase --> prophase --> metaphase --> anaphase --> telophase

A group of scientists test three different types of cells – muscle cells, nerve cells, and skin cells – to find out which cell type goes through the steps of mitosis the fastest. The scientists time 100 cell divisions for each type of cell. The temperature and amount of light is the same for all of the cells. What is a or constant in this investigation?

• The speed of the divisions

• The types of cells

• The temperature

• The age of the scientists

What does meiosis create?

• Skin cells
• Reproductive (or sex) cells
• Only egg cells
• Nerve cells

Select the best description of a chromosome.

• material used to form the cell membrane
• tightly wound DNA that is ready for cell division
• long, stretched out strands of DNA
• molecules that form the sex cells

In which phase does a cell spend most of its time?

• interphase

• prophase

• metaphase

• telophase
