Crossing-over of chromatid segments during meiosis division I results in the formation of genetic variation.
<span>Crossing-over is an event during the meiosis (during prophase I)<span> and represents the exchange of genetic material between non-sister chromatids of homologous chromosomes. As a result of it, the creation of new combinations of genes on each chromosome occur. The exchange can happen many times within the same pair of homologous chromosomes, creating unique combinations of alleles.</span></span>

Crossing over of chromatid segments during meiosis division 1 results in new gene combinations.  Cross over occurs between prophase 1 and metaphase 1 and is the process where homologous chromosomes pair up with each other and exchange different segments of their genetic material to form recombinant chromosomes. Additionally, it can happen during mitotic division ; which may result in loss of heterozygosity.

<span>AUTOTROPH 1. an organism that can make its own food

Plants like algae are autotrophs. They produce their own food with the use of light, carbon dioxide, water, and other chemicals that are vital in their food producing activity. Aside from plants, there are autotroph organisms. An example of this is phytoplanktons. 

CALVIN CYCLE 2. the dark reaction process of photosynthesis that uses carbon dioxide for the synthesis of carbohydrates

The Calvin Cycle has three phases. These are 1) carbon fixation, 2) reduction reactions, and 3) RuBP regeneration. 
This cycle occurs in the stroma of the chloroplast and it converts carbon dioxide and other chemical compounds into glucose.

CAROTENOID PIGMENT 3. a pigment ranging in color from yellow to red; helpful in capturing the Sun's light energy for use in photosynthesis

Carotenoid is a plant pigment. It produces yellow, orange, and red colors of many fruits and vegetables. Carotenoid pigment is identified as a class of phytonutrients that benefits human health. People who consumes carotenoid rich fruits and vegetables enjoys the antioxidant property of the food as well as the Vitamin A that some carotenoid convert into. 

CHLOROPHYLL 4. a green pigment in plants that serves to trap the Sun's energy for photosynthesis

Chlorophyll is the combination of two Greek words "chloros" and "phyllon" which means green and leaf respectively. This pigment also contributes to human wellness as consumption of plants rich in chlorophyll are proven to be very healthy. These health benefits are 1) helps fight cancer, 2) improves liver detoxification, 3) speeds up the healing of wounds, 4) improves digestion and helps control weight, and 5) protects skin from skin virus like cold sores.

CHLOROPLAST 5. the tiny body that contains chlorophyll; part of the cell in which photosynthesis takes place

Chloroplast is a type of plastid that can be distinguished from other plastids due to its green color. Chloroplast is the only plastid that contains chlorophylls a and b, thus its green color. 

PHOTOSYNTHESIS 6. a process that involves the use of carbon dioxide and water in the production of glucose and oxygen using the Sun's energy

RADIATION 7. transfer of heat or energy through rays of various wavelengths

</span><span>Radiation is defined as energy travelling through space. Sunshine or sunlight is an example of radiation. Its ultra violet rays radiates heat on the earths' surface which in turn helps our autotrophs undergo photosynthesis.
