The image on the right shows the cell structure of the epidermis of an onion (screen magnification 100X). This layer is only one cell thick and therefore the individual cells and the cell membranes can be clearly seen, as well as the nucleus which is the small dark spot in most cells.

Where in the cell are the chloroplasts located? Scattered Inside the cytoplasm.

Answer Expert Verified. The organelles are the chloroplasts. To this phenomenon where the cytoplasm moves in a direction within the cell we call cyclosis, or cytoplasmic streaming.

The other, much more complex, type of cell is called the eukaryotic cell. Like prokaryotic cells, eukaryotic cells have cell membranes, cytoplasm, ribosomes, and DNA. However, there are many more organelles within eukaryotic cells.

Archaea: Structure, Characteristics & Domain The cell is the smallest living organism that contains all the features of life, and most all life on the planet begins as a single-cell organism.

Atoms cannot be created or destroyed. Atoms of different elements may combine with each other in a fixed, simple, whole number ratios to form compound atoms.

According to Dalton’s Atomic Theory, Atoms of one element cannot be changed into atoms of a different element by chemical reactions and atoms can neither be created nor destroyed in chemical reactions. The basic unit of matter is known as atoms.

Do atoms reproduce? In the sense that living organisms reproduce, no, atoms do not reproduce. Some atoms are radioactive and decay into other atoms. Some emit “alpha” particles when they decay.

When we die, our atoms will disassemble and move off to finds new uses elsewhere – as part of a leaf or other human being or a drop of dew. Atoms themselves, however go on practically forever.

As it turns out, atoms do have a finite lifespan, because protons have a finite lifespan. Eventually, protons will decay into short lived subatomic particles. This will happen in 10^32 years. Or 100 nonillion years.

There can’t be an infinite number of any material object: not atoms, not subatomic particles, not quarks. The existence of empty space means that the number of material objects of any kind is finite. Originally Answered: Are atoms limited in the universe?

As we know through thermodynamics, energy cannot be created nor destroyed. It simply changes states. The total amount of energy in an isolated system does not, cannot, change. We can gain energy (again, through chemical processes), and we can lose it (by expelling waste or emitting heat).

Therefore they can not die. As far as we know, the electron is a fundamental point particle with no internal structure, so there is no way for the electron to fall apart in smaller pieces.

Protons—whether inside atoms or drifting free in space—appear to be remarkably stable. We’ve never seen one decay. However, nothing essential in physics forbids a proton from decaying. In fact, a stable proton would be exceptional in the world of particle physics, and several theories demand that protons decay.

That is the question asked by a physicist in Germany, who has calculated the lower limit for the lifetime of the photon to be three years in the photon’s frame of reference. This translates to about one billion billion (1018) years in our frame of reference.

No. Stable atoms do not decay. The only problem is that it is very difficult to tell whether a particular isotope is stable or just extremely long at decaying. Bismuth-209 used to be thought of as stable.
