Answer: Chlorophyll
Explanation:
Chlorophyll is the photosynthetic pigment found in the chloroplasts of green plants. It helps the plants to trap solar energy radiated from the sun during day light. This energy trapping by chlorophyll occurs during the Light-dependent stage (first stage) of photosynthesis, followed by Light-independent stage (second stage)
Animals with bilateral symmetry can be divided equally along only one plane.

Non-prokaryotic organisms typically have two life cycle stages: trophozoite and cyst is Protozoa.
<h3>What is Protozoa?</h3>
- Protozoa is a group of single celled, non- prokaryotic organisms.
- These may either be free living or parasitic in nature.
- These are heterotrophs and reproduce asexually by binary fission.
- The Protozoa consists of many unrelated or loosely related organisms.
- They are divided into four major groups: Sarcodina, Flagellates, Ciliates and Sporozoans..
- Some protozoa consist of two phases in their life cycle: proliferative stage (trophozoites) and resting stage (cysts).
- Trophozoites consists of the proliferative stage in which the protozoa divides and reproduces.
- The resting cyst form helps the protozoa to survive harsh environmental conditions like harmful chemicals, extreme temperature and nutrient and water deficiency.

The correct answer is: introns
Processing of mRNA is process that occurs only in eukaryotic cells. After the transcription, newly formed mRNA molecule is called and it must be processed into a messenger RNA (mRNA). Processing includes:
• Addition of a 5' cap to the beginning of the RNA
• Polyadenilation- addition of a poly-A tail (tail of A nucleotides) to the end of the RNA
• Splicing- removal of introns and linking the exons
After these steps mRNA is mature and used for the further steps (e.g. translation).
Sometimes some genes are alternatively spliced.
