The chromosomes are separated by a structure called the mitotic spindle.
A chromosome is a lengthy DNA molecule with component or all of the genetic material of an organism. In maximum chromosomes the very lengthy skinny DNA fibers are lined with packaging proteins; in eukaryotic cells the maximum vital of those proteins are the histones. These proteins, aided by chaperone proteins, bind to and condense the DNA molecule to keep its integrity. These chromosomes show a complicated third-dimensional structure, which performs a large position in transcriptional regulation.
Chromosomes are generally seen below a mild microscope best for the duration of the metaphase of molecular division.

In order for plants to produce energy and maintain cellular function, their cells undergo the highly intricate process of photosynthesis. Critical in this process is the stoma. Stomata (multiple stoma) are located on the outermost cellular layer of leaves, stems, and other plant parts. An open stoma facilitates the process of photosynthesis in three ways. First, it allows light to enter the intercellular matter and trigger the process. Second, it allows for the uptake of carbon dioxide, a key chemical in producing plant energy. Third, it allows for oxygen to be expelled into the outside environment, a byproduct of photosynthesis that is no longer needed by the cell.
Answer:
Chloroplasts
Explanation:
Chloroplasts are found in cells of leaves and green parts of the stem. They contain green pigment called chlorophyll which makes photosynthetic cells to appear green. They are sites of photosynthesis. Chlorophyll traps light energy from the sun. The energy is used to drive the manufacture of sugars from carbon dioxide and water, a process called photosynthesis.
