Question: What Do Bubbles Mean In Photosynthesis?

What does the number of bubbles tell about the rate of photosynthesis of a plant?

More oxygen bubbles are produced when the light is closer to the beaker.

So a greater light intensity gives a greater rate of photosynthesis..

What are the bubbles really showing photosynthesis Virtual Lab?

The bubbles are produced when water plants perform photosynthesis. Oxygen is created and you can see the plant “breathe it out” as tiny bubbles. The bubbles will be coming from the bottom of the stem. Your job is to count how many bubbles are produced for each test for 30 seconds.

How do you show that oxygen is produced during photosynthesis?

Expose the apparatus to the sunlight. After few hours, gas bubbles will form and collect in the test tube. Test the gas in the test tube. A glowing splinter bursts into the flame shows the presence of oxygen.

What is the relationship between sodium bicarbonate and photosynthesis rate?

The more sodium bicarbonate present, there is a greater amount of carbon dioxide present, which in result will increase the speed of photosynthesis.

What is your hypothesis for this experiment the rate of photosynthesis?

The hypothesis tested was: If the plants are at a lower temperature, the rate of photosynthesis would be more rapid. … The independent variable in the experiment was the temperature of the chamber. The dependent variable was the carbon dioxide concentration over time.

What does a low number of oxygen bubbles indicate about photosynthesis?

These bubbles can be counted and the rate of bubbling can serve as an indication of the rate of photosynthesis. When the light intensity is increased, the rate of bubble production should increase. … The rate of photosynthesis should decrease and therefore the amount of oxygen bubbles should decrease.

Does elodea produce oxygen?

A pure carbon dioxide environment makes the Elodea produce more oxygen than Elodea grown in a normal atmosphere environment. All materials a plant needs to undergo photosynthesis and produce oxygen are carbon dioxide, sunlight, and water.

Which colors of the light spectrum are most important for plant growth Virtual Lab answers?

Lab 1: Glencoe Photosynthesis Lab If red and blue are absorbed more by the plant then red and blue will be the most effective and green will cause the least plant growth.

Where does the light reaction of photosynthesis take place quizlet?

Where does the light reaction of Photosynthesis take place? In the thylakoid membrane.

What do plants do with extra glucose?

What do plants do with the extra glucose that they produce? They use it to produce carbohydrates , proteins, and fats. These are used as sources of stored energy.

What molecules make up the bubbles you count?

They might just as well have been bubbles of nitrogen or carbon dioxide, or some other gas from some other process that was occurring in the plants instead of photosynthesis. Nevertheless, since the plants were exposed to light, the bubbles were most likely made of oxygen.

What are the bubbles really showing?

The bubbles show the rate of photosynthesis by counting the amount of oxygen released (the bubbles). The more bubbles released, the faster the rateof photosynthesis.

How will photosynthesis affect oxygen levels quizlet?

Photosynthesis increases if the amount of oxygen is decreased. A high level of oxygen is a limiting factor. A plant deficient in chlorophyll will absorb less light, which will lower the rate of photosynthesis.

How will cellular respiration affect oxygen levels?

Cellular respiration can occur both aerobically (using oxygen), or anaerobically (without oxygen). During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts. In cellular respiration, glucose and oxygen react to form ATP.

What three things are used to make glucose in photosynthesis?

Rather, plants use sunlight, water, and the gases in the air to make glucose, which is a form of sugar that plants need to survive. This process is called photosynthesis and is performed by all plants, algae, and even some microorganisms.

What is an example of photosynthesis?

An example of photosynthesis is how plants convert sugar and energy from water, air and sunlight into energy to grow. The water from the leaves evaporates through the stomata, and filling its place, entering the stomata from the air, is carbon dioxide. Plants need carbon dioxide to make food.

What are the 4 factors that affect photosynthesis?

Photosynthesis is affected by light, temperature, water, and CO2. Stomata affect the process of transpiration and do not affect photosynthesis.

What is the define of photosynthesis?

Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.

Why do bubbles tell you how fast photosynthesis is occurring?

Why do the bubbles tell you how fast photosynthesis is occurring? The bubbles are oxygen that we are measuring. Since the plants need CO2 to create oxygen, the more bubbles there are, the faster photosynthesis is occurring.

Why is the number of oxygen bubbles considered a measure of the rate of photosynthesis?

Dependent Variables Rate of Photosynthesis/ Number of Oxygen Bubbles The rate of photosynthesis is measured by the counting of number of released bubbles which is oxygen. … If the water amount increases, then the photosynthesis rate will increase. After a period of time photosynthesis rate remains constant.

What is the relationship between oxygen and photosynthesis?

Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.
