Answer (2)
In a multiple-choice format, the answers to the biology questions are as follows: 8(b), 9(b), 10(c), 11(a), 12(b), 13(c), 14(b), and 15(b). Each answer reflects the classification or adaptation relevant to the respective question. These selections are based on common biological understanding of plants and animals.
;
Tomato is a shrub: A tomato plant is considered a shrub because it is a woody, perennial plant that has multiple stems. A shrub is generally smaller than a tree and often grows to a medium height, typical of tomato plants in gardens.
Long legs adaptation in camels: Camels survive in cold deserts due to adaptations like long legs which elevate their bodies to keep them away from the blazing hot ground during the day, and insulated from the cold ground at night. They also have a thick fur layer that provides protection against both heat and cold.
Pea has tap roots: Among the options given, pea plants have a taproot system. Taproots are characterized by a single, large central root from which smaller lateral branches arise. This adaptation helps in anchoring the plant and accessing deeper water sources.
Grass has fibrous roots: Grasses typically have a fibrous root system, which consists of many small branching roots that spread out horizontally and vertically. This root type is effective for absorbing nutrients and water from the upper layers of soil.
Forests and Grasslands are examples of terrestrial habitats: Terrestrial habitats are ecosystems found on land rather than in water. Both forests and grasslands fit this description as they support land-dwelling plants and animals.
Frogs are examples of amphibians: Amphibians are cold-blooded vertebrates that can live both on land and in water. Frogs fit this definition as they are well-adapted to life in both environments through their skin and respiratory systems.
Roots, stems, and leaves help in storage of food: These parts of plants can store nutrients, energy reserves, or water. Roots often store energy in the form of starch, stems can store water in succulent plants, and leaves can store food in the form of starch or glucose.
Climbers are plants that climb with support: Climbers are plants that use other plants or structures to support themselves as they grow upward. This allows them to access sunlight efficiently by extending their foliage beyond ground level.
