Reproduction & Development — Drills · Grade 10 Science
Chapter: Cell Division, Reproduction & DevelopmentWhat these drills covers
By the end of Reproduction & Development you should be able to:
- I can connect meiosis and fertilization with chromosome-number continuity.
- I can describe development as regulated division, differentiation, and organization.
2 questions, written answer, each with a worked explanation.
Vocabulary used: gamete, zygote, development.
Problem 1
Why should a reproductive model state which organism it describes?
Answer and explanation
Different groups have different life cycles, chromosome stages, and routes for making gametes.
Problem 2
Connect meiosis, fertilization, and development in three sentences.
Answer and explanation
Meiosis produces haploid gametes in the animal model. Fertilization combines gametes to form a diploid zygote. Regulated division, differentiation, and organization develop tissues and organs.
