Aquatic Plant Adaptations and Characteristics

The video tutorial explores the adaptations of aquatic plants, focusing on fixed plants like water lilies and lotus. It categorizes aquatic plants into fixed, floating, and underwater types. The tutorial highlights the adaptations of stems and leaves in fixed plants, such as hollow stems and waxy-coated leaves, which aid in floating and protection. It also explains the unique placement of stomata on the upper surface of leaves to facilitate gas exchange in water.

What defines an aquatic plant?

• A plant that lives and grows in water

• A plant that only grows in deserts

• A plant that grows in soil

• A plant that can survive without sunlight

Where can aquatic plants be found?

• Only in freshwater bodies

• In oceans, rivers, lakes, and ponds

• Only in rivers

• Only in oceans

How are aquatic plants categorized?

• By their color

• By their size

• Into fixed, floating, and underwater plants

• By their age

What is a characteristic of the stems of fixed aquatic plants?

• They are thick and strong

• They are solid and heavy

• They are hollow and light

• They are short and rigid

Why are the stems of fixed aquatic plants hollow?

• To help leaves float

• To store water

• To anchor the plant

• To absorb more sunlight

What adaptation helps the leaves of fixed aquatic plants float?

• Being flat and broad

• Being thick and heavy

• Being narrow and thin

• Being round and small

What is the purpose of the waxy coating on the leaves of aquatic plants?

• To attract insects

• To absorb more water

• To prevent rotting and sinking

• To change color

Where are stomata located on the leaves of fixed aquatic plants?

• On the stem

• On the upper surface

• On the underside

• On the edges

Why are stomata on the upper surface of aquatic plant leaves?

• To attract pollinators

• To avoid water contact

• To store nutrients

• To absorb more sunlight

What would happen if stomata were on the underside of aquatic plant leaves?

• They would help the plant grow faster

• They would be ineffective due to water contact

• They would function better

• They would absorb more carbon dioxide
