Why hydrilla plants are used in the experiment?

Because hydrilla is a small plant and hence easy to handle and also it is a aquatic plant so it is able to breath in water whereas land plants are not. Explanation: hydrilla is an aquatic plant. So, it makes it easier to setup the experiment.

What are the characteristics of hydrilla?

Hydrilla is a hardy, fast-growing, herbaceous perennial with long, slender stems that can grow to some 7 metres (23 feet) in length. The leaves grow in pairs or in whorls of three to eight and are small, lance-shaped or oblong, and distinctly toothed.

What special feature of hydrilla makes it an invasive species of plant for the American continent?

HYDRILLA IS BEST KNOWN FOR ITS TENDENCY TO COMPLETELY TAKE OVER A WATER BODY. DENCE INFECTIONS OF HYDRILLA CAN SHADE OR CROWD OUT ALL NATIVE AQUATIC PLANTS, AFTER WATER CHEMISTRY, CAUSE DRAMATIC SWINGS IN DISSOLVED OXYGEN LEVELS, INCREASE WATER TEMPERATURES AND AFFECT THE DIVERSITY AND ABUNDANCE OF FISH POPULATION.

What type of photosynthesis have we found in hydrilla?

The submersed monocot, Hydrilla verticillata (L.f.) Royle, is a facultative C4 NADP-malic enzyme (ME) species (Bowes et al. 2002). In nature it typically exhibits C3 photosynthesis.

What is the conclusion of Hydrilla experiment?

Result of the experiment

Now a glowing splinter is introduced into the test tube by removing the thumb from the mouth of the test tube. The glowing splinter immediately burst into a flame indicating that the gas collected in the test tube is oxygen.

What is Hydrilla experiment?

Hydrilla experiment is performed to show that oxygen is produced during the process of photosynthesis. Aim : to demonstrate that oxygen is produced during the process of photosynthesis. ... Material required : hydrilla plant , test tube , barker, water , funnel.

What is the difference between hydrilla and elodea?

closer, Brazilian elodea leaves have smooth edges and no spines on the midrib of the leaf and whorls of four to six leaves, whereas hydrilla has serrations on the leaf edge and spines on the midrib of the leaf and whorls of five leaves. Native elodea has whorls with three leaves.

How does hydrilla affect the ecosystem?

Hydrilla poses serious ecological threats. Its ability to grow in various conditions gives it an advantage that allows it to out-compete native plants. Infestations of hydrilla can be harmful to fish populations as well. Large infestations can cause oxygen depletion zones which can lead to fish kills.

How did the hydrilla become invasive?

Hydrilla was first brought to the United States intentionally to sell as an aquarium plant. Today it is spread primarily by human activities. ... Hydrilla has been spread by careless pet owners dumping plants from aquariums into ponds and streams.

What would have happened if hydrilla had a strong and stiff stem and huge leaves?

ANSWER: The hydrilla are aquatic plant. The strong stem of hydrilla would have resulted in less stability in floating and also would have restricted photosynthesis reaction based on huge leaves.

What is the adaptation of hydrilla?

The main adaptations that give hydrilla an advantage over other native plants are: It is a submerged hydrophyte found attached to the substratum by adventitious roots in freshwater ponds. It can grow at low light intensities until it nears the water surface, where it gets sunlight.

Why would we use an aquatic plant elodea SP for this experiment instead of a terrestrial plant?

A water plant such as elodea (the type you commonly see in aquariums) does the process of photosynthesis just as plants that grow in the air do, but you can actually see the bubbles that indicate photosynthesis is occurring--they form on the leaves before they float to the surface, enabling an easy measurement of ...

Does hydrilla produce carbon dioxide?

Hydrilla, like all plants, gives off CO2 and uses oxygen during the night time (although the opposite is true during the day), which can bring oxygen levels to dangerously low levels for fish.

What is photosynthesis explain with equation?

The process of photosynthesis is commonly written as: 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.
