Grade 11 Biology | Quick Check for Understanding
| # | Answer | Explanation |
|---|---|---|
| 1 | The series of stages an organism goes through during its life. | A life cycle begins when an organism starts life and continues through growth, reproduction, and death. |
| 2 | Birth | An organism must begin life before it can grow and reproduce. |
| 3 | seed | A seed is the beginning stage in the life cycle of many flowering plants. |
| 4 | egg → larva → pupa → adult | Butterflies undergo complete metamorphosis in this order. |
| 5 | False | Different organisms have different life cycle patterns and numbers of stages. |
| 6 | Seedling | After germination, the seed grows into a young plant called a seedling. |
| 7 | Development | Development includes growth and changes in body form and function. |
| 8 | Metamorphosis | Metamorphosis is a major change in body form during development. |
| 9 | B) Larva | A larva is an organism stage; the other choices are life processes or physical changes. |
| 10 | Resources such as food, water, space, and suitable conditions. | Life cycles depend on environmental resources and conditions for survival and growth. |
| 11 | adult | Adult is the final stage in complete metamorphosis. |
| 12 | Incomplete metamorphosis does not include a pupa stage. | Incomplete metamorphosis usually includes egg, nymph, and adult stages. |
| 13 | True | In incomplete metamorphosis, the nymph resembles the adult form. |
| 14 | B) Grasshopper | Grasshoppers develop from egg to nymph to adult without a pupa stage. |
| 15 | To increase the chance that some offspring survive. | Many offspring may not survive, so producing more can improve survival of the species. |
| 16 | Seed formation | After pollination and fertilization, seeds develop inside the plant. |
| 17 | The process by which organisms produce offspring. | Reproduction passes genetic information to the next generation. |
| 18 | Asexual reproduction | Asexual reproduction produces offspring from one parent without fusion of gametes. |
| 19 | True | Sexual reproduction combines genetic information from two parents, increasing variation. |
| 20 | Asexual reproduction | Runners allow new plants to grow from one parent without seeds. |
| 21 | A) Juvenile stage | Juvenile stages often involve rapid growth and development. |
| 22 | Temperature can speed up or slow down growth and development. | Many organisms develop faster in warmer conditions up to a limit, and slower in cooler conditions. |
| 23 | The eggs may not survive or hatch successfully. | Without enough water, the eggs cannot complete early development. |
| 24 | A) They help organisms reproduce and maintain populations | Life cycles allow species to continue from one generation to the next. |
| 25 | seedling | A seedling is the early growth stage of a plant after germination. |
| 26 | They grow and develop through stages, such as caterpillar to butterfly or tadpole to frog. | Many animals pass through distinct stages as they mature. |
| 27 | To understand growth, reproduction, survival needs, and population changes. | Knowing life cycles helps explain how species live and how their populations are affected. |
| 28 | It helps the farmer target the most vulnerable stage for control. | Understanding the life cycle can make pest control more effective. |
| 29 | A butterfly has complete metamorphosis with a pupa stage, while a grasshopper has incomplete metamorphosis without a pupa stage. | This comparison highlights the key difference between the two life cycles. |
| 30 | Answers will vary; students should name one mastered idea and one topic to review. | Reflection helps students and teachers identify strengths and next steps. |
