Deep Thinking
Why is identical DNA important in body cells?
So cells function properly and consistently
What comes after metaphase?
Anaphase
What happens if chromosomes don’t separate evenly?
Cells get unequal DNA
Which process helps replace dead skin cells?
Mitosis
What is mitosis?
Division of a cell into two identical cells
Why is variation important in species?
Helps survival and adaptation
What is the correct PMAT order?
Prophase, Metaphase, Anaphase, Telophase
If a cell skips interphase, what happens?
DNA is not copied correctly
Which process is used in reproduction?
Meiosis
What is interphase?
Stage where cell grows and copies DNA
Why must DNA be copied before division?
So each cell gets complete genetic information
What stage is DNA pulled apart?
Anaphase
What happens if meiosis doesn’t occur?
No reproductive cells are formed
Which process produces genetically different cells?
Meiosis
What are daughter cells?
New cells formed after division
Why do organisms need both mitosis and meiosis?
Mitosis for growth, meiosis for reproduction
Which phase lines up chromosomes?
Metaphase
What if mitosis produced different cells?
Body cells would not function properly
Which process is used during growth?
Mitosis
What are chromosomes?
Structures that carry DNA
Explain why mitosis must produce identical cells
To maintain normal body function
First step of mitosis?
Prophase
What happens if meiosis produces identical cells?
No genetic variation occurs
Which process explains why siblings look different?
Meiosis
What is genetic variation?
Differences in DNA between organisms
