Life Cycles Challenge Practice
| # | Answer |
|---|---|
| 1 | A life cycle is the series of stages a living thing goes through from beginning to adulthood and, in many cases, to reproduction. |
| 2 | Examples include a butterfly, frog, plant, bird, or human. |
| 3 | The first stage is often an egg or a newborn young. |
| 4 | The child stage comes after the baby stage. |
| 5 | Plants need water, sunlight, air, and nutrients from soil. |
| 6 | Metamorphosis is a major change in body form during a life cycle, such as from caterpillar to butterfly. |
| 7 | A butterfly goes through those stages. |
| 8 | The larva stage is the caterpillar stage. |
| 9 | The pupa stage is the chrysalis stage. |
| 10 | The tadpole stage comes after the egg stage. |
| 11 | A tadpole has a tail and no legs at first, while an adult frog has legs and no tail. |
| 12 | Germination is when a seed begins to grow into a new plant. |
| 13 | The root usually grows first. |
| 14 | Roots absorb water and hold the plant in the ground. |
| 15 | Pollination is the transfer of pollen from one flower to another flower or to another part of the same flower. |
| 16 | Insects, wind, birds, and other animals can help with pollination. |
| 17 | Flowers help plants reproduce and make seeds. |
| 18 | A seed is the part of a plant that can grow into a new plant. |
| 19 | Egg, larva, pupa, adult. |
| 20 | Seed, sprout, young plant, mature plant. |
| 21 | A mature plant can produce flowers, fruits, or seeds. |
| 22 | Reproduction is when living things produce offspring. |
| 23 | It allows a species to continue from one generation to the next. |
| 24 | An offspring is a child or young member of a living thing. |
| 25 | A frog changes form greatly, but a human grows from baby to adult without metamorphosis. |
| 26 | A plant begins as a seed and grows roots and leaves, while an insect begins as an egg and may change form. |
| 27 | It suggests that the stages repeat in a pattern. |
| 28 | The teenage or adolescent stage usually comes after childhood. |
| 29 | The juvenile, child, or adolescent stage comes before adulthood. |
| 30 | Young animals often need help for food, protection, and survival. |
| 31 | A generation is a group of living things born around the same time, or the people or organisms in a family line at one stage. |
| 32 | A seed germinates, grows roots and a shoot, develops leaves, and becomes a mature plant. |
| 33 | A seedling or young plant is one stage before flowering. |
| 34 | The flower can produce fruit and seeds. |
| 35 | The larva, or caterpillar, stage eats the most food. |
| 36 | It is important because the caterpillar grows quickly and stores energy for later stages. |
| 37 | They help us understand how living things grow, change, and reproduce. |
| 38 | Both involve clear stages of growth and change over time. |
| 39 | A frog begins as an egg, becomes a tadpole, grows legs, and changes into an adult frog. |
| 40 | A plant grows from a seed into a mature plant, then makes flowers, seeds, and new plants. |
