1.ORGANS OF ABSORPTION
- A.
  
  ROOT
- B.
  
  STEM
- C.
  
  LEAF
- D.
  
  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.

2.THE HABITAT OF WATER HYACINTH
- A.
  
  TERRESTRIAL
- B.
  
  DESERT
- C.
  
  AQUATIC
- D.
  
  MOUNTAIN
Correct Answer
C. 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
- A.
  
  True
- B.
  
  False
Correct Answer
B. 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.

4.GREEN PLANTS NEED SUNLIGHT
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Green plants need sunlight for photosynthesis, the process by which they convert sunlight into energy. Sunlight provides the necessary energy for plants to produce glucose, which is used as fuel for growth and development. Without sunlight, plants would not be able to produce enough energy to carry out their essential functions and would eventually die. Therefore, it is true that green plants need sunlight to survive and thrive.

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.

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.
