What will happen if chloroplast is taken out of cell and illuminated?
weqwewe [10]
Photosynthesis is an important process in plants in which they produce glucose which serves them as food. This process occurs in the green leaves of the plants, thanks to the green pigment chlorophyll in the organelles known as chloroplasts.
If the question is what will happen to the plant, it will no longer have green leaves, and the rate of photosynthesis will be significantly decreased, but not stopped because there will probably be other pigments (non-green) able to <span>absorb sunlight.
</span> If the question is what will happen to <span>chloroplast if it is taken out of the cell and illuminated, i</span>ts pigment chlorophyll will absorb red and blue light,and reflects green light.

During this phase of mitosis, the mitotic spindle forms and the nuclear envelope fragments.
Arisa [49]

Mitotic spindle forms and the nuclear envelope fragments at the prophase stage of mitosis.

<h3>What are the stages of mitosis?</h3>

Mitosis has 4 main stages that are more or less in a continuous spectrum. These stages are:

  • Prophase
  • Metaphase
  • Anaphase
  • Telophase

The prophase stage is characterized by the dissolution of the nuclear envelope, the condensation of chromatin materials, and the onset of spindle formation.

The metaphase stage is characterized by the alignment of chromosomes at the equator and the engagement of each chromosome by spindle fibers at the centromere.

The separation of sister chromatids characterizes the anaphase through the shortening of the spindle fibers from the opposite ends of the cell.

The telophase is characterized by the completion of the migration of sister chromatids to the poles.

Thus, the mitotic spindle forms and the nuclear envelope fragments at the prophase stage of mitosis.
