They could improve the experiment that they made by adding another variable such as: watering the plants with fresh water. This way they could have a better comparison how plants grow based on the type of water they are exposed with.

When the food is scarce, cellular slime molds aggregate into a mass of cells that behaves as a single unit called a slug.
<h3>What is the importance of slugs in slime molds?</h3>
- While feeding, the cellular slime molds live as individual, singled-celled organisms. But when the food is scarce and they have to move to new places in search of food, they aggregate in groups of tens of thousands to form multicellular group called slugs.
- In slug some of the cells contribute to a 2–3 millimeter long stalk, which dries up and dies in the process of formation.
- In the presence of excess food, slime molds are present as independent amoeboid cells.
- It is now observed that in the presence of a food source, some farmer amoebae stop feeding and pocket their food for movement in multicellular migration.

Mitochondrial DNA (mtDNA) typing is used in forensic science for it serves as an important tool in determining the recovered damaged, degraded or small sample source of the DNA. Mitochondrial DNA is a small genome that is found in the mitochondria, just outside of the nucleus of the cell. Usually, hair, bones, and teeth are the most common samples that are being examined for mtDNA.
Plant cells are a form of eukaryotic cells with true nucleus and organelles. Various types of plant cells are -xylem cells, phloem cells ,parenchyma cells, collenchyma cells and sclerenchyma cells. These cells distinguish plants from animal kingdoms.
In desert plants like cactus, they have an exquisite set of adaptations for optimal water management. They have thickened stem tissues with thin-walled parenchyma cells so a lot of water can be stored in stems.
