Green plants and certain other animals use a process called photosynthesis to convert light energy into chemical energy. Sunlight is the primary, non-recyclable, and easily accessible component of photosynthesis.
In the electromagnetic radiation that the Sun emits, sunlight is included. Water (H2O) and carbon dioxide (CO2) are ingested by plants during photosynthesis from the soil and atmosphere. In contrast to carbon dioxide, which is reduced within the plant cell and obtains electrons, water is oxidised within the cell of the plant. Due to this, carbon dioxide and water are converted into glucose and oxygen, respectively.
We can therefore conclude that green plants and some other animals convert light energy into chemical energy through a process known as photosynthesis. The most important, easily accessible, non-recyclable element in photosynthesis is sunlight.

The alternation of generations
in the life cycle of a plant includes the diploid and haploid multicellular
stages. diploid and haploid are copies of the chromosomes. The spores in the
plant is unicellular and when they start dividing through mitosis, it produces
identical cells. These identical cells are all haploid. Haploid stages contain
one set of chromosome from either of the parent. These identical cells create a
multicellular system called the gametophytes. A gametophyte is the haploid
multicellular stage in the life cycle of a plant. The gametophyte makes the
gametes. These gametes are responsible for sexual fertilization. It takes place
when a sperm (male gametes) from the male fuses into the egg cell (female
gametes) of the female. The formation of both
male and female gametes creates a diploid zygote. Diploid stages
contain one set of chromosome from each parent. This is where the sporophyte
comes in. A sporophyte is the diploid multicellular stage in the life cycle of
the plant. It now contains the two sets of chromosomes from each parent.
The type of
cell division that produces gametes with half the normal chromosome number is
the meiosis. Meiosis is the type of cell division used in sexual reproduction.
It will occur in the testes and ovaries.

Channel protein is important because it is embedded in the membrane and it also covers the membrane. This is important because the channel must transport the micromolecules and ions in and out of the cell. Carrier proteins are important because the carrier must transport the molecule in and out of the cell.
