Brassica Rapa can be described as a flowering plant that is commonly used in genetic experiments aswell as plant growth. Within 35-40 days this plant is able to go through a complete life cycle with the help of artificial slection. This allows students, such as myself, to be able to examine, study, and research the entire life cycle throughout school.
Following the instructions of my grade 11 biology teacher:
1 - A film canister was filled up 2/3 with soil, and watered until the soil was damp and water was dripping through the wick at the bottom.
2 - Three fertilizer seeds were added to the damp soil, followed by more soil placed on top.
3 - More water was added to moisten the soil.
4 - The Brassica Rapa seeds were added on top of the soil, along with loose soil sprinkled on top of the seeds, allowing the film canister to be filled.
This was the beginning of the experiment, and the starting of a new life for my Brassica Rapa.

Helpful Definitions:
Meristems: Area of a plant where some cells retain the ability to repeatedly by mitosis.
Aprical Meristems: Regions at the plants tips of all roots and shoots. Responsible for primary growth that throughout the life of the plant lengthens the shoots and roots.
Lateral Meristems: Cylindrical regions in roots and stems. The increased diameter of roots and shoots is the result of these.
Vascular Cambium: A lateral meristem that is responsible for producing new phloem and xylem tissue within the plant.
Photosynthesis: The process in which plants use chlorophyll to trap the energy from sunlight and use it to produce carbohydrates.
Primary Growth: All growth in the length of roots and stems that occur throughout the plants entire life and all growth in the diameter of roots and stems within the 1st year of the plants life.
Secondary Growth: Plant growth that takes place at lateral meristems which result in increased diameters of roots and stems in the second and subsequent years of a plants life.
Epidermis: The outer layer of a multicellular plant that experiences primary growth.
Periderm: A protective coating that replaces the epidermis in plants that live after its primary growth.
Axillary Bud: A new bud born on the axil of a leaf that will later on branch into a shoot or flower cluster.
Pollination: In flowering plants, pollen is transferred from the anther of the plant to the stigma, often by the wind or by insects such as bees. This process happens in order for plants to develop seeds later on in their life cycle.
Nodes: The location in which leaves are attached to the stem.
Internode: The space between two nodes on the same side of a plants stem.
Simple Leaf: A leaf that is not divided into two or more leaflets.
Compound Leaf: A leaf that is divided into two or more leaflets.
