What are the green bodies observed in the guard cells?
The green bodies observed in guard cells are chloroplasts, which contain chlorophyll and are responsible for photosynthesis in plants. Chloroplasts help to convert light energy into chemical energy, which is essential for the production of glucose and oxygen during photosynthesis.
How will you know when photosynthesis is occurring in your leaf disks?
Photosynthesis in leaf disks can be detected by observing the buoyancy of the disks as they float. When photosynthesis occurs, oxygen is produced as a byproduct, causing the disks to become buoyant and rise to the surface of the water. Typically, this process can be observed through a change in the position of the disks within a given time frame, indicating that photosynthesis is actively taking place. Additionally, an increase in the number of floating disks over time serves as a clear indicator of photosynthetic activity.
Who discovered plastid in cell?
The plastid was discovered by German scientist Andreas Schimper in the late 19th century. He observed these specialized organelles in plant cells and described their role in photosynthesis and other cellular processes.
Why isn't chloroplasts observed?
Chloroplasts may not be observed in certain cells or tissues because they are primarily found in plant cells and some algae, where photosynthesis occurs. Additionally, in non-photosynthetic cells, such as those in roots or certain specialized tissues, chloroplasts are absent. Environmental factors, such as light availability, can also influence chloroplast development and visibility, as they are more prominent in cells exposed to sunlight.
How do you put photosynthesis in syllables?
The correct spelling is 'photosynthesis'.
What did Joseph priestly do in photosynthesis?
He observed and proved that plants release the oxygen we need to breathe.
What are the green bodies observed in the guard cells?
The green bodies observed in guard cells are chloroplasts, which contain chlorophyll and are responsible for photosynthesis in plants. Chloroplasts help to convert light energy into chemical energy, which is essential for the production of glucose and oxygen during photosynthesis.
What is a simple photosynthesis experiment that can be conducted to demonstrate the process of photosynthesis?
One simple photosynthesis experiment is to place a small plant in a clear plastic bag with a small amount of water and seal it. Place the bag in sunlight for a few hours. The plant will release oxygen during photosynthesis, which can be observed as bubbles forming in the water. This demonstrates how plants use sunlight to produce oxygen.
What characteristics of filamentous algae can be observed under a microscope?
Under a microscope, characteristics of filamentous algae that can be observed include long, thread-like structures, cell walls, chloroplasts for photosynthesis, and sometimes reproductive structures like spores or gametes.
Why is oxygen the dependent variable in photosynthesis?
Oxygen is the dependent variable in photosynthesis because its production is directly influenced by the independent variable, which is typically the light intensity, CO2 concentration, or temperature. The amount of oxygen produced by the plant depends on the conditions provided for photosynthesis, making it the variable that is being measured or observed in the experiment.
TW Engelmann was the first to observe that photosynthesis required?
TW Engelmann observed that photosynthesis required light, demonstrating this by exposing algae to different colors of light and noting that oxygen was only produced in response to specific wavelengths in the blue and red regions of the spectrum.
What describes a hypothesis?
State the changed and observed variable. E.g.: the higher the intensity of the light, the higher the rate of photosynthesis. Heehee I'm pretty certain I'm correct. And I'm 12! Haha
Is it possible there is no photosynthesis?
No, photosynthesis is a fundamental process in plant biology where plants use sunlight to convert carbon dioxide and water into glucose and oxygen. Without photosynthesis, plants would not be able to produce energy and oxygen, which is essential for the survival of many organisms on Earth.
The early suggestion that oxygen liberated from plants during photosynthesis comes from water was?
The early suggestion that the oxygen (O2) liberated from plants during photosynthesis comes from water was first published by Melvin Calvin, who also discovered the Calvin cycle. It was confirmed by experiments using oxygen-18 (18O).
Who discovered plastid in cell?
The plastid was discovered by German scientist Andreas Schimper in the late 19th century. He observed these specialized organelles in plant cells and described their role in photosynthesis and other cellular processes.
What bests describes a hypothesis?
it is directly testable APEX
Can we use the before observed in the phrase it is observed?
no
