The cellular structure that was visible in the transmission electron micro graph but not visible in the cells when microscope was used is NUCLEOLUS.
The transmission electron micro graph is a microscopy method that involves using electrons beams to form image of specimens. Transmission electron micro graph can be used to view minute structures of the cell because of its higher optical capacity.
The nucleolus was not seen under the microscope because is a very small cell structure.
Calcium can be found in eggs,milk,meat,etc
Calcium is not a rare element

The 3 - carbon molecules formed in the light independent reactions of photosynthesis are important precursors to the main products of photosynthesis namely glucose, starch and cellulose. They are necessary for making these end products
The 3 - carbon molecules that are formed are:
1. 3- phosphoglycerate (3-PGA) - formed in the first stage of light independent reactions when a molecule of carbon dioxide gas is attached to a molecule of ribulose. The newly formed 6 -carbon sugar quickly breaks down into two identical 3 carbon molecules, 3 -PGA.
2. Glyceraldehyde 3 phosphate (G3P) - formed when one phosphate molecule is removed from 3 - PGA.
G3P is then used to make glucose, sucrose, starch, cellulose and other carbohydrates essential for the plant.
