Why do floating plants have spongy roots?
Plants float because of the presents of air spaces between the plant cells. Air is more buoyant than the surrounding water, predominantly causing the biological mass of cells containing the air to float on the water’s surface rather than sink.
Photosynthetic organisms capture energy from the sun and matter from the air to make the food we eat, while also producing the oxygen we breathe. In this Snack, oxygen produced during photosynthesis makes leaf bits float like bubbles in water.
During photosynthesis, plants convert light, water, and carbon dioxide from the air into oxygen and sugars. In this activity, you will be able to observe the oxygen production in leaves by doing a floating leaf disk experiment. You can also find out how quickly plants produce oxygen, and what variables affect photosynthesis.

How do plants convert light energy into chemical energy? What happens during the floating leaf disk assay? What environmental factors do you think affect the rate of photosynthesis?
Jul 12, 2023 · Why do some trees appear green in the summer but change colors in the fall? What optimal wavelengths (or peaks) did you observe for both chlorophyll a and b? Do your leaf disks float? Use the information in this diagram of a cross-section of a leaf to explain why a leaf disk would float. Figure \(\PageIndex{1}\): Copy and Paste Caption here.
Oct 31, 2023 · In hot climates, plants such as cacti have succulent leaves that help to conserve water. Many aquatic plants have leaves with wide lamina that can float on the surface of the water; a thick waxy cuticle on the leaf surface that repels water.
In this lab, students explore the process of photosynthesis in spinach leaves. As oxygen is produced, the density of the leaves change and they will begin floating in a sodium bicarbonate solution. The time it takes for a certain number of leaves to float can be used to calculate the rate of photosynthesis. • 1.
