What adaptation helps the fleshy stems of plants found in the desert survive the hot conditions?
  • The fleshy stems of plants found in the desert can store water and help them tolerate the hot conditions.
  • The fleshy stems of plants found in the desert can absorb sunlight to make food quickly.
  • The fleshy stems of plants found in the desert can grow very tall to avoid heat.
  • The fleshy stems of plants found in the desert can produce flowers to attract pollinators.
In order to survive in extremely cold regions with frequent snowfall, what adaptation do some trees have?
  • Some trees have the ability to let the snow slide off easily due to their conical shape and sloping branches.
  • Some trees have brightly colored leaves to absorb more sunlight.

What are the differences you observe between hot desert camels and cold desert camels, and what advantages do these differences provide to these camels?
  • Hot desert camels have long legs and wide hooves for walking on sand, while cold desert camels have shorter legs and narrower feet for mountainous regions.
  • Hot desert camels have short legs and narrow feet for walking on rocks, while cold desert camels have long legs and wide hooves for sand.
  • Both types of camels have the same leg and hoof structure for all terrains.
  • Hot desert camels have furrier bodies for cold, while cold desert camels have less fur for heat.
The long legs and wide hooves of camels in the hot desert help them walk on the sandy desert without sinking into the sand.
  • True
  • False
Camels in the cold desert have taller bodies and longer necks than those in the hot desert.
  • True
  • False
In deserts, food is not available easily. Camels store food in their humps. Camels found in the hot desert have ___ hump each.
  • one
  • two
  • three
  • four
Fill in the blank: Camels found in the cold desert have ___ humps each.
  • two
  • one
  • three
  • four
In deserts, food is not available easily. Camels store food in their humps. Camels found in the hot desert have one hump each that helps them to survive during the scarcity of food. Camels found in the cold desert have two humps each. These two humps shrink in late winters because there is not much food available in the cold desert and they have to use food stored in their humps during that time. Moreover, they grow long hair from head to neck, which help them survive the cold winters of Ladakh.
  • True
  • False
Camels can survive for many days without drinking water because they do not lose much ___ from their bodies.
  • water
  • heat
  • food
  • energy
Maya talks about seeing plants with beautiful bright flowers, rhododendrons, in the Shola forests of Nilgiris. Here, rhododendrons are of shorter height and have smaller leaves to survive through the heavy winds on mountain tops. However, Pema, who is from Sikkim, has observed rhododendrons in the nearby mountains to be taller. So, even plants such as rhododendrons may exhibit different features in different regions to survive the conditions of those regions.
  • Tall height
  • Short height and small leaves
  • Large leaves
  • No flowers
