Answer (2)
The lotus plant has broad, flat leaves with a waxy coating, which helps it float on water. Aquatic plants are mentioned broadly, including examples like water lilies and mangroves for different environments. Fleshy desert plants like cacti store water and nutrients, adapting them to survive in harsh conditions.

I. Multiple-Choice Question:
Which of the following is the feature of a lotus plant?
The correct answer is: a. The leaves are broad and flat with waxy coating
Lotus plants have large, circular leaves that are broad and flat. These leaves often have a waxy coating to help them repel water, which is essential for floating on water surfaces.
II. Fill in the Blanks:
Plants that grow in plains have many branches .
Plants growing in plains generally spread out widely and develop many branches as they have ample space and resources like sunlight and nutrients.
The plants growing in water are called aquatic plants .
Aquatic plants are adapted to live in water environments, and they can be either fully submerged or floating on the surface.
The fleshy stems of desert plants store water and nutrients .
Desert plants, such as cacti, have adapted to survive in dry conditions by storing water and essential nutrients in their thick, fleshy stems.
Underwater plants have thin and ribbon-like leaves.
These features help them move with water currents and maximize absorption of sunlight while minimizing water resistance.
Cactus is an example of a desert plant.
The cactus has adaptations like thick skin and fleshy stems that help it survive in arid desert conditions.
III. Answer the Following in One Word:
What are plants bearing cones called?
Conifers
Conifers are gymnosperms, and they produce seeds not in flowers but in cones.
Give one example of a floating aquatic plant.
Water lily
Water lilies are common examples of floating aquatic plants, known for their beautiful flowers.
Name the plant growing in marshy or swampy areas.
Mangrove
Mangrove plants are well adapted to grow in marshy and swampy areas and play important roles in coastal ecosystems.
Give an example of a plant growing in the coastal areas.
Coconut
Coconut trees are often found growing in coastal areas and are well adapted to survive in sandy, salty environments.
What protects aquatic plants from getting rotten?
Waxy coating
The waxy coating on leaves of many aquatic plants is crucial in preventing excess water absorption, thus protecting them from rotting.
