Students sequence the stages of various life cycles on an educational worksheet.

The task involves sequencing the life cycles of different organisms in the correct order. Below, I will explain how to solve each sequence step by step.

1. Plant Life Cycle

The images show the stages of a plant's life cycle. The correct sequence is:

1. Seed: The starting point of the plant's life.
2. Sprout (Germination): The seed begins to grow roots and a shoot.
3. Young Plant: The sprout develops into a young plant with leaves.
4. Mature Plant: The plant grows fully and produces flowers or fruits.
5. Flower/Fruit: The mature plant produces flowers or fruits, which contain seeds for the next generation.

Correct Order:
Seed → Sprout → Young Plant → Mature Plant → Flower/Fruit

2. Frog Life Cycle

The images show the stages of a frog's life cycle. The correct sequence is:

1. Egg: Frogs lay eggs in water.
2. Tadpole: The eggs hatch into tadpoles, which are aquatic and have tails.
3. Tadpole with Legs: As the tadpole grows, it develops hind legs and then front legs.
4. Froglet: The tadpole loses its tail and becomes a froglet, transitioning from an aquatic to a semi-aquatic lifestyle.
5. Adult Frog: The froglet matures into an adult frog, capable of reproduction.

Correct Order:
Egg → Tadpole → Tadpole with Legs → Froglet → Adult Frog

3. Chicken Life Cycle

The images show the stages of a chicken's life cycle. The correct sequence is:

1. Egg: Chickens lay eggs, which are the starting point of their life cycle.
2. Chick: The egg hatches into a chick.
3. Juvenile Chicken: The chick grows into a juvenile chicken.
4. Adult Chicken: The juvenile chicken matures into an adult chicken, capable of laying eggs.

Correct Order:
Egg → Chick → Juvenile Chicken → Adult Chicken

4. Human Life Cycle

The images show the stages of a human's life cycle. The correct sequence is:

1. Baby: Birth marks the beginning of human life.
2. Toddler: The baby grows into a toddler, learning to walk and talk.
3. Child: The toddler develops into a child, growing physically and mentally.
4. Teenager: The child enters adolescence and becomes a teenager.
5. Adult: The teenager matures into an adult, capable of reproduction and independent living.

Correct Order:
Baby → Toddler → Child → Teenager → Adult

5. Butterfly Life Cycle

The images show the stages of a butterfly's life cycle. The correct sequence is:

1. Egg: Butterflies lay eggs on leaves.
2. Caterpillar: The eggs hatch into caterpillars, which are worm-like larvae.
3. Pupa (Chrysalis): The caterpillar forms a chrysalis, where it undergoes metamorphosis.
4. Butterfly: The adult butterfly emerges from the chrysalis.

Correct Order:
Egg → Caterpillar → Pupa → Butterfly

Final Answer

Here is the complete solution for all sequences:

1. Plant Life Cycle: Seed → Sprout → Young Plant → Mature Plant → Flower/Fruit
2. Frog Life Cycle: Egg → Tadpole → Tadpole with Legs → Froglet → Adult Frog
3. Chicken Life Cycle: Egg → Chick → Juvenile Chicken → Adult Chicken
4. Human Life Cycle: Baby → Toddler → Child → Teenager → Adult
5. Butterfly Life Cycle: Egg → Caterpillar → Pupa → Butterfly

Boxed Final Answer:
\[
\boxed{
\text{1. Seed → Sprout → Young Plant → Mature Plant → Flower/Fruit} \\
\text{2. Egg → Tadpole → Tadpole with Legs → Froglet → Adult Frog} \\
\text{3. Egg → Chick → Juvenile Chicken → Adult Chicken} \\
\text{4. Baby → Toddler → Child → Teenager → Adult} \\
\text{5. Egg → Caterpillar → Pupa → Butterfly}
}
