Blogpost #8 - Jolene Hayes

The plant has doubled in size. It is about 18 inches tall, with leaves that are 7-10 inches. It has gotten wider and is now 21 inches wide. The color has changed, too. Before, it was yellow and looked unhealthy. Now, it is turning into more of a grey color. the leaf stems and the stock are a purple color. The plant has a dry texture. I noticed that the leaves have very small thorns on it, which is a defense mechanism to keep bugs away. It is starting to flower a lot more.  These traits (height, color) are examples of natural variations. With selective breeding, the plants get natural variations. The plants genes determine the species but there will still be variations because every plant is different. All of the plants in the garden I saw had different variations. The other plants had different leaves and sizes. Some plants were as small as 8 inches, while others were about 20 inches. With descent with modification, the Brassica plant can have 7 variants. Mutation is one of the causes of variants. To create a stronger or more unique plant, people could use artificial selection. This would make beneficial variations that could be passed on to the next generation of plants.

Blogpost #7 - Jolene Hayes           Flowers in the Aster or Asteraceae family, including every dandelion species, have a flowered head. The base of the dandelion head is made up of involucre which is a bunch of green bracts. Ligules is what  the petals of the dandelion flower are called. The fuzzy ring at the end of a flower is pappus. The pappus develops into a feather like seed. The traits of the pappus are what is needed to seperate the species in this family. There is a very tiny tube inside with nectar. The stigma grows up through the tube where the ovary and pollen are. It is protected by the anthers. The stigma can split in two at the end of it.

Blogpost #6 - Jolene H     There was not very much growth in the plant. It looks similar to last time but there are more holes from the snails and they are starting to turn a bit yellow. It has gotten a bit bigger because of photosynthesis . The cells inside the plant grow larger with the sun and then split up in twos. This is called mitosis . Duplicating takes a lot of energy. The PKG is an enzyme that helps turn the sunlight energy into chemical energy to help biomass . Cellular respiration  is the process of oxidizing food molecules, like glucose, carbon dioxide and water. The released energy is trapped in the form of ATP for use by all the energy consuming activities of the  cell . All these things are needed to keep a plant alive and healthy.
