Kds Coaching answered |
Plants with parallel venation, like grass and wheat, usually have a fibrous root system. This root system consists of many thin roots of similar size spreading out from the base of the stem. In contrast, plants with reticulate venation, like hibiscus, have a taproot system with one main root and smaller side roots branching off. This relationship between venation and root type is a common characteristic used to group plants.
What is the importance of grouping plants and animals?- a)It simplifies the study and understanding of their diversity.
- b)It helps in decreasing biodiversity.
- c)It ensures that only useful species are preserved.
- d)It focuses on individual species rather than ecosystems.

Understanding Adaptations
Adaptations are essential features or behaviors that enable plants and animals to thrive in their specific environments. These adaptations can be structural, behavioral, or physiological and are crucial for survival.
Why Adaptations Matter
- Survival: Adaptations help organisms to survive in their habitats by providing necessary tools for coping with environmental challenges.
- Resource Utilization: Different adaptations allow species to efficiently utilize available resources such as food, water, and shelter. For example, cacti have thick skins to retain water in arid environments.
- Predator and Prey Dynamics: Adaptations can enhance an organism's ability to evade predators or improve its hunting capabilities. For instance, the camouflage of certain animals helps them blend in with their surroundings.
- Reproductive Success: Adaptations can also affect reproduction. Brightly colored flowers attract pollinators, while certain animal behaviors ensure successful mating.
Types of Adaptations
- Structural Adaptations: Physical features of an organism, such as the long neck of a giraffe for reaching high leaves or the thick fur of polar bears for insulation.
- Behavioral Adaptations: Actions taken by organisms to survive. For instance, migratory patterns in birds help them find suitable climates and food sources.
- Physiological Adaptations: Internal processes that enhance survival, like the ability of some reptiles to tolerate extreme temperatures.
Conclusion
In essence, adaptations are fundamental to the survival and thriving of both plants and animals in their respective environments. They enable species to meet the demands of their surroundings, ensuring their continued existence and evolution.

Coders Trust answered |
A camel is perfectly suited for desert life. It has special features like:
- A hump to store fat, which it can use as energy when food is scarce.
- The ability to survive without water for many days because it stores water in its body.
- Long legs and wide hooves to walk on sand without sinking.
- It does not sweat much, so it loses very little water.
Other animals like zebras and frogs need more water, and penguins live in cold places, not deserts.
