Flashcard 1: What is the correct order of a flowering plant life cycle using these steps: seed, seedling, adult plant, flower, fruit?

Answer: Seed → seedling → adult plant → flower → fruit (with seeds). Flowering plants reproduce through seeds in fruits.

Flashcard 2: Identify the correct order for a flowering plant life cycle: seed, adult plant, seedling, flower.

Answer: Seed, seedling, adult plant, flower. Correct sequence from seed to reproductive stage.

Flashcard 3: Which option best compares a butterfly and a grasshopper life cycle: complete or incomplete metamorphosis?

Answer: Butterfly: complete; grasshopper: incomplete. Butterflies have 4 stages; grasshoppers have 3.

Flashcard 4: What is a nymph in insects with incomplete metamorphosis?

Answer: A young stage that looks like a small adult but cannot reproduce. Gradually grows wings and reproductive parts.

Flashcard 5: Which type of metamorphosis has three stages: egg, nymph, adult?

Answer: Incomplete metamorphosis. Grasshoppers and dragonflies skip the pupa stage.

Flashcard 6: What is the larva stage in many insects?

Answer: A feeding and growing stage after the egg hatches. Larvae eat and grow before transforming.

Flashcard 7: Which insect life cycle is complete metamorphosis: egg–larva–pupa–adult or egg–nymph–adult?

Answer: Egg–larva–pupa–adult. Complete metamorphosis has four distinct stages including pupa.
