- 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. Aquatic plants are well adapted to floating on water for their entire life cycle.

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.

The enormous flow of water through the plant isn’t simply waste and the price the plant pays for having stomata open for oxygen and carbon dioxide exchange. Transpiration also: Provides water for photosynthesis (although not that much is needed — only about 1–2% of what is transpired).
In a process called photosynthesis, plants convert light energy, water, and carbon dioxide into oxygen and sugar. They can then use the sugar as an energy source to fuel their growth. Scientists have found an easy way to measure the rate of photosynthesis in plants. The procedure is called the floating leaf disk assay.
Jul 11, 2023 · You will use the "floating leaf disk" method to measure the rate of photosynthesis. To begin, cut several disks from a spinach leaf and put these leaf disks in a cup of water. 1. 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. 2. Where does photosynthesis occur ...
Jun 30, 2019 · Watch spinach leaf disks rise and fall in a baking soda solution in response to photosynthesis. The leaf disks intake carbon dioxide from a baking soda solution and sink to the bottom of a cup of water. When exposed to light, the disks use carbon dioxide and water to produce oxygen and glucose.
