Peduncle: Flower stock
Receptacle: The part of a flower are attached to the stalk.
Sepal: The outer parts of the flower that enclose a developing bud.
Petal: The parts of a flower that are often conspicuously colored.
Stamen: The pollen producing part of a flower.
Anther: The pollen is produced in this part of the stamen.
Pistil: The ovule producing part of a flower. The mature ovary is a fruit, and the mature ovule is a seed.
Stigma: The part of the pistil where pollen germinates.
Ovary: The enlarged basal portion of the pistil where ovules are produced.

Progress of the Seeds (Days 1 - 8)
Day 1
On the first day there was no germination of the seeds and because of the dry soil, the seeds were watered.
Day 2
All the seeds had germinated except for one in the cold water tray. The soil was still damp from watering it the day before.
Day 3
All the seeds have sprouted and the soil was watered due to dryness.
Day 4
All the seeds had sprouted and the soil was still damp. It was discovered that the stem for the cold water seeds were growing at a different rate due to a difference in height. The hot water seeds' stems were relatively the same height.
Day 5
The soil was slightly dry and the decision was made to change the experiment to salt water (which replaced hot water), and cold water, because of the possibility of killing the plants due to the high temperature of the water. The hot water seeds had grown to 1 cm and were basically the same size for all. Three of them had true leaves showing. For the cold water seeds, they were all different sizes ranging from 0.5 cm to 1.5 cm. There was only one stem that had a true leaf.
Day 6
The soil was damp. The salt water plants all had the presence of true leaves and not grown. However the cold plants had grown to the height of 0.5 cm to 2 cm.
Day 7
The salt water plants had grown to a height of 2 cm. They had been watered the night before. The cold plants now have a range of height between 1.5 cm to 2 cm.
Day 8
All of the results are basically the same as Day 7 and the soil was damp. The leaves had grown in size for both collections of the plants.

Getting to Know the Pansy
Violas were first cultivated by Lady Mary Elizabeth Bennet. Today there are more than 125 species of the flower.
Taxonomy of the pansy is:
Kingdom - Plantae
Class - Magnoliapsida
Order - Violales
Family - Violaceae
Genus - Viola
Species - Tricolour
Sub-Species - Viola Trihortensis
The pansy has many medicinal uses for asthma, epilepsy, skin disease, and eczema. It is also edible. Providing food for herbivores and pollinating insects is one of the pansy's role in the environment. Its predators include aphids, snails, and slugs.
There are two top petals which overlap and there are two side petals. The last part of the anatomy of the pansy includes a bottom petal which has a slight indentation.

Charles Darwin
Born ; February 12 1809 in England
Died ; April 19 1882 at the age of 75 in UK
Darwin's interest in nature made him leave his medicinal studies and pursue his studies in natural science at the university of Edinborough.
He is known for the voyage of the Beagle, the voyage began December 27th 1831 and lasted almost 5 years where he went to the islands of the Galapagos. Discovered all species come from a common ancestor, the scientific theory of branching patterns of evolution as the result of natural selection (over production, competition, variation, survival of the fittest, and the origins of new species), where species evolved to survive and thrive in their environment while the others died off.
