Quiz about Living Things
Questions and Answers
- 1.
Green plants make their own _________________
Explanation
Green plants make their own food through a process called photosynthesis. They use sunlight, carbon dioxide, and water to produce glucose and oxygen. This glucose serves as their source of energy, which they use for growth, reproduction, and other metabolic processes. This ability to produce their own food sets green plants apart from other organisms, as they are able to sustain themselves without relying on consuming other organisms for nutrition.Rate this question:
- 2.
Animals lay _________ or produce babies.
Explanation
Animals lay eggs as a means of reproduction. This is a common method among many species, including birds, reptiles, fish, and some mammals. Eggs provide a protective environment for the developing embryo and allow for external fertilization. The process of laying eggs is crucial for the survival and continuation of many animal species.Rate this question:
- 3.
Plants breathe through ___________________ in their leaves.
Explanation
Plants have small openings called pores, also known as stomata, on the surface of their leaves. These pores allow for the exchange of gases, including oxygen and carbon dioxide, between the plant and its environment. Through these openings, plants take in carbon dioxide for photosynthesis and release oxygen as a byproduct. Additionally, the pores also help regulate water loss from the plant through transpiration. Therefore, it can be concluded that plants breathe through pores in their leaves.Rate this question:
- 4.
Animals ______________ in search of food.
Explanation
Animals move in search of food because they need to find sustenance to survive. Moving allows them to explore different areas and habitats where they can find sources of food. Animals have different strategies for finding food, such as hunting, foraging, or scavenging. By constantly moving, animals increase their chances of encountering food resources and meeting their nutritional needs. This behavior is essential for their survival and is a fundamental instinct ingrained in their biology.Rate this question:
- 5.
Both plants and animals _________ in size.
Explanation
Plants and animals both undergo a process of growth in size. This growth involves an increase in the number and size of cells, resulting in an overall increase in the size of the organism. This growth is essential for both plants and animals to develop and mature. Therefore, the correct answer is "grow."Rate this question:

_____________________ is a flower that shows movement.
- 7.
Fish breathe through
- A.
Spiracles
- B.
Fins
- C.
Gills
- D.
Lungs
Correct Answer
C. GillsExplanation
Fish breathe through gills, which are specialized organs that extract oxygen from water. Gills are located on the sides of a fish's head and consist of thin filaments that are rich in blood vessels. As water passes over the gills, oxygen from the water diffuses into the fish's bloodstream, while carbon dioxide is released. This allows fish to extract oxygen from their aquatic environment and is essential for their survival. Unlike lungs, which are used by mammals and some other animals to extract oxygen from the air, gills are specifically adapted for extracting oxygen from water.Rate this question:

__________________ is a characteristic of non - living things.
- A.
Movement
- B.
Reproduction
- C.
Lifeless
- D.
Growth
Correct Answer
C. LifelessExplanation
The characteristic of "lifeless" refers to non-living things. Non-living things do not possess the ability to move, reproduce, or grow. They lack the essential biological processes that are associated with living organisms. Therefore, "lifeless" is the correct answer as it accurately describes the characteristic of non-living things.Rate this question:

Living things move to _____________________________
- A.
Get food
- B.
For clothing
- C.
For fun
Correct Answer
A. Get foodExplanation
Living things move to get food because food is essential for their survival and to meet their energy requirements. Moving allows them to search for sources of food, such as plants or other animals, and to access different areas where food might be available. Movement also helps living things to avoid predators and competition for limited food resources. Therefore, the ability to move is crucial for living things to ensure their survival and obtain the necessary nutrients for growth and reproduction.Rate this question:

A tree has ____________ to fix itself firmly in the soil
- A.
Leaf
- B.
Root
- C.
Flower
- D.
Fruit
Correct Answer
B. RootExplanation
A tree has roots to fix itself firmly in the soil. Roots play a vital role in anchoring the tree and providing stability. They also absorb water and nutrients from the soil, which are essential for the tree's growth and survival. Without roots, a tree would not be able to stand upright or obtain the necessary resources for its sustenance.Rate this question:

A seed grows into a small plant is called _________________________
- A.
Caterpillar
- B.
Kitten
- C.
Seedling
- D.
Tad pole
Correct Answer
C. SeedlingExplanation
A seedling is the correct answer because it refers to a young plant that has grown from a seed. As the seed begins to germinate and sprout, it develops into a seedling. This stage is characterized by the emergence of leaves and the development of a small root system. The term "seedling" specifically describes the early growth stage of a plant, making it the most appropriate choice among the given options.Rate this question:
