Test: Plants and Animals - Class 5 MCQ

Terrestrial animals primarily breathe through lungs. This respiratory system allows for the exchange of gases necessary for their survival. It is a key feature that distinguishes them from aquatic animals that may breathe through gills or specialized skin.

Amphibians like frogs have a unique respiratory system where they are able to breathe through their skin as well as their lungs. This dual method of respiration allows them to extract oxygen from both water and air, adapting to their semi-aquatic environments.

Herbivores, such as cows and rabbits, primarily obtain their food by consuming plants. Their digestive systems are specialized to break down plant matter and extract nutrients from it, supporting their growth and survival.

Carnivores are characterized by their diet of consuming other animals. This predatory behavior is a crucial aspect of their ecological role, where they help maintain balance in food chains by controlling the populations of other species.

Green plants primarily make their food through the process of photosynthesis. This complex biochemical reaction utilizes sunlight, water, and carbon dioxide to produce glucose, the key energy source for the plant's growth and development.

Plants do not move from place to place like animals, but they do exhibit movements in response to environmental stimuli. For example, roots may grow towards water sources, while leaves adjust their positions to optimize sunlight absorption, showcasing their adaptive behaviors.

Animals have specialized sense organs that allow them to respond quickly and effectively to stimuli in their environment. These sensory adaptations help them detect dangers, find food, and navigate their surroundings efficiently.

Plants primarily reproduce through seeds and various other methods like cuttings, grafting, and layering. This diverse range of reproductive strategies allows for genetic diversity and the propagation of plant species in different environmental conditions.

Unlike animals that typically stop growing after reaching a certain size, plants exhibit continuous growth throughout their lives. This indeterminate growth pattern allows plants to adapt to changing environmental conditions and continue their development over time.

Some plants, such as the bristlecone pine, have exceptional longevity and can live for thousands of years. This remarkable feature highlights the resilience and adaptability of certain plant species to survive and thrive in diverse ecological settings.
