Below are sample questions representative of the exercises included on this worksheet and related 3.33 Identify Life Cycle Stages in Images skill assessments:

Problem 1Difficulty: Mastery
Student A says, 'A picture of a hen on eggs is stronger evidence for reproduction than a picture of a single adult hen.' Student B says, 'Both pictures show reproduction equally well because both hens are adults.' Which student has the better claim?
AStudent A is correct: eggs or newborns are stronger clues for reproduction than adult size.
BStudent B is correct: any large organism must be in reproduction.
CBoth students are correct because adult size and eggs mean the same thing.
DNeither student can use picture clues to identify stages.
Solution & Explanation:Eggs give direct picture evidence of offspring, so they show reproduction more clearly than adult size alone.
Problem 2Difficulty: Mastery
A tomato life cycle strip shows birth first and reproduction third. Which picture should go in the second position between them?
Aa leafy young tomato plant
Ba wilted brown tomato plant
Ca tomato plant with flowers and fruit
Da seed just cracking open
Solution & Explanation:The second position should show the plant growing bigger before it begins reproduction.
Problem 3Difficulty: Mastery
Why is a picture of a single adult plant or animal sometimes not enough to call the stage reproduction?
ABecause adult size alone does not prove the organism is making young or seeds.
BBecause all adults must be in the birth stage.
CBecause only dead organisms can reproduce.
DBecause size is the only clue that matters in life cycles.
Solution & Explanation:Reproduction needs direct evidence such as eggs, babies, flowers, fruits, or seeds, not just adult size.
