Day 27 - Monday, April 19, 2010
Unfortunately, I believe this is close to the end for my plant. The blades of the leaves are slowly dying, becoming very fragile, as well as crinkly and turning purple, yellow and orange. The cotyledons are finally dying off, and the several seed pods that remain are becoming very hard and brittle. Additionally, the shoot of my plant is also becoming very hard and brittle.
Day 21 - Tuesday, April 13, 2010
My plant is continuing to maintain its health, the petioles and blades both flourishing. A few axillary buds were present once again, so they were plucked off the plant. Over night several seed pods have formed and are quickly developing. There are nodes near the bottom of the plant, located near the petioles.
Surprisingly, it appears the leaves of my plant now look similar in shape to a Populus leaf (Poplar tree) however, much more rigid.
Day 20 - Monday, April 12, 2010
A few seed pods are beginning to grow on my plant, signifying it's nearing the end of it's life cycle. The blades of my leaves have continued to stay strong and have grown even larger. However, the withered cotyledons on my plant are beginning to die off. Additionally, I needed to pluck a few axillary buds from my plant to ensure it conserves it's energy in the remaining days of it's survival.
Day 17 - Friday, April 9, 2010
The cotyledons on my plant have started to wither, but hopefully my plant can maintain their survival for a little while more. The blades of my leaves have successfully grown strong again and are no longer shriveled. My plant has produced a few more flowers, with several apical meristems present within the axillary buds.
Day 16 - Thursday, April 8, 2010
My plant has now grown to 15cm tall, averaging a 1cm increase each day over the last two days. I am continuing with the cross pollination and as a result several flowers have now almost fully bloomed.
It appears that the blades of my leaves have begun to droop and wither, possibly due to lack of water, however, hopefully they will continue to survive. Additionally, there doesn't appear to be any young leaves or axillary buds in the process of growing at the moment.
Day 15 - Wednesday, April 7, 2010
Over the last week or so, there has been a huge development in my plant, growing from the previous 4.5cm to 13cm as of today. Along with the massive increase in height, my plant has began to flower beautifully, with several axillary buds still in the process of blooming into additional flowers.
The leaves of my plant still resemble the shape of an Oak trees leaves, growing larger each day to absorb more sunlight for energy. My plant is now starting to form cotyledons which will eventually start to wither throughout the end of it's life cycle.
It was a necessity to pluck off the several axillary buds to conserve the plants energy and allow it to live longer. Today was also the day that cross pollination started, by gluing a dead bee to a skewer and transferring the pollen from another plant onto my plant.
Day 9 - Thursday, April 1, 2010
The plant is now around 4.5cm to 5cm in height with many new developments over night. There is clear vascular/dermal tissue within the stem of the plant, the epidermis producing a waxy surface called the cuticle, protecting the plant from infection.
There is also the development of nodes, and the space in between them; internodes. Additionally, it appears there is now the formation of young leaves, axillary buds, and the continuous growth of the shoot tip (teriminal bud).
Day 8 - Wednesday, March 31, 2010
A new baby leaf is beginning to grow, adding to a total of six developing leaves. Branching off of the shoot, petioles are starting to form. The blades are also evident in the plant, as well as ground tissues.
The leaves are showing signs of having net venation. The leaves also appear to be simple leaves and resemble a Quercus leaf (Oak tree) in terms of shape. (Please refer to: Leaves)

The beginning of a new life...
Brassica Rapa is a flowering plant commonly used in plant growth and genetic experiments. Through artificial selection, scientists have selected traits that allow this plant to complete its life cycle in 35-40 days, allowing us to study it's plant growth in that duration.
During Grade 11 Biology class, we filled film canisters 2/3's of the way with soil and then added water until the soil was damp and dripping through the wick at the bottom. Next, three fertilizer seeds were added on the dampened soil. Additional soil was placed overtop of the fertilizer seeds with more water added to dampen the soil. The Brassica Rapa seeds were finally added to the film cansiter, with additional soil sprinkled over top of them.
This is the life cycle of the Brassica Rapa.
