B. Is carbon dioxide needed for photosynthesis?
1. Destarch the plant (remove previously made starch from plant)
2. a. cut the leaf in 2
b. 1 part in a box with CO2 absorber and 1 part in box with a CO2 provider
3. Test for starch (BEWI)
C. Is chlorophyll needed for photosynthesis?
1. Destarch the plant (remove previously made starch from plant)
2. Use a variegated leaf
3. Test for starch (BEWI)
B E W I
1. Put leaf in boiling water to destroy the cell membrane and denature enzymes
2. Ethanol in a hot water bath to remove chlorophyll
3. Warm water to soften the leaf
4. Add drops of iodine solution
Explanation:
Electron microscopes use _beam of electrons___ in order to allow for higher magnification and more detail when viewing specimens.
Explanation:
A beam of electrons has a shorter wavelength than normal light used in light microscopes, by approximately a factor of X 100000. Therefore, electrons microscope have the inherent attribute of having a very high resolution. They have been used to discover very small organelles in cells such as the ribosomes and mitochondria that cannot be clearly viewed even with the highest resolution in light microscopes.

Answer:
so what’s the question?
Answer:
Organization and effectiveness of cellular tasks
Explanation:
Cell is the fundamental unit of all living organisms where all biochemical processes responsible for the functioning of the living organism occurs. However, each cell is made up of smaller compartments or areas that run a specific biochemical process called ORGANELLES.
An organelle can be likened to a section of a house, where different activities are conducted. This enables the cellular processes to be organized and effective due to the fact that each organelle/compartment has its own specific task. The work/processes that are key to the survival of an organism are specifically allocated to organelles in a cell. For example, ribosomes conduct protein synthesis, mitochondrion performs energy production etc.
In a nutshell, this small areas or organelles in the cell makes the biochemical process easy, organized and effective.
