Grade 8 reproduction and growth compare mitosis with meiosis and asexual with sexual reproduction. Students track how DNA is copied, how gametes get half the chromosome number, and how fertilization restores it. Environment can still affect growth even when the genetic instructions are inherited.

What you practice

These are the Grade 8 Reproduction & Growth skills this quiz is built around.

Contrast mitosis (growth and repair) with meiosis (gametes with half the chromosomes).
Compare asexual reproduction, which makes genetically similar offspring, with sexual reproduction.
Describe how plant seeds or animal development depend on both genes and conditions.

A useful tip

Meiosis halves the chromosome number so fertilization can restore the species number. If gametes were diploid like body cells, chromosome counts would double each generation.
