    2.THE HABITAT OF WATER HYACINTH

    • TERRESTRIAL

    • DESERT

    • AQUATIC

    • MOUNTAIN

    Correct Answer
    A. AQUATIC
    Explanation
    The correct answer is "AQUATIC" because water hyacinth is a plant that grows and thrives in water. It is a floating plant that has long roots that hang in the water, allowing it to absorb nutrients and oxygen from the water. Water hyacinth is commonly found in freshwater bodies such as lakes, ponds, and slow-moving rivers. It forms dense mats on the water surface, which can have negative impacts on the ecosystem by blocking sunlight and reducing oxygen levels for other aquatic organisms.

    3.PLANTS CAN LIVE WITHOUT WATER

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Plants cannot live without water as water is essential for their survival. Water is required for various important processes in plants such as photosynthesis, nutrient absorption, and transportation of nutrients. Without water, plants would not be able to produce food, grow, or maintain their structure. Lack of water can lead to wilting, dehydration, and ultimately death of the plant. Therefore, the statement "Plants can live without water" is false.

    1.ORGANS OF ABSORPTION​​​​​​​

    • ROOT

    • STEM

    • LEAF

    • FLOWER

    Correct Answer
    A. ROOT
    Explanation
    The root is one of the organs of absorption in plants. It is responsible for absorbing water and nutrients from the soil. The root system consists of root hairs that increase the surface area for absorption. This allows the plant to take in water and minerals needed for growth and development. The stem, leaf, and flower also play important roles in the plant's overall function, but they are not primarily responsible for absorption.

    6.FIXATION AND ABSORPTION ARE MAIN FUNCTIONS OF ___________

    Correct Answer
    ROOT,root,Root
    Explanation
    The main functions of the root are fixation and absorption. The root anchors the plant in the soil, providing stability and support. It also absorbs water and nutrients from the soil, which are essential for the plant's growth and survival. Therefore, the correct answer is root.

    5.EARTH'S SURFACE IS COVERED BY _______PERCENTAGE OF WATER

    Correct Answer
    75
    Explanation
    The Earth's surface is covered by 75% of water. This means that approximately three-fourths of the Earth's surface is composed of water bodies such as oceans, seas, lakes, and rivers. This high percentage of water coverage is one of the defining characteristics of our planet and plays a crucial role in sustaining life. The presence of such a significant amount of water also influences weather patterns, climate, and the overall balance of ecosystems on Earth.
