An Abiotic factor that our Brussel sprouts depends on for survival is water. Water is a non living factor to the environment and everything in it. Plants and animals depend on it to survive animals to hydrate and help there prey/food grow and plants for the process of photosynthesis. A Biotic factor that some plants depend on for survival is human impact. Some plants depend on human impact get water and to be fed and grow in a healthy environment.

Our plants are engaged in competition because there are multiple plants in one area and some plants are doing much better than others. Our plants are competing for room for their roots to grow, soil nutrients, water, and sunlight. Our plants are in completion with the other plants in it's garden bed competing for resources to survive.

Winners and losers in this completion are determined by what plant grows and what plants don't. The winners and losers aren't always crystal clear even though sometimes they can be. This is true because some plants can grow better than the others but the loser might get just enough nutrients to survive or grow.

An interaction that occurs with our Brussel sprouts is parasitism an example of this in the garden the caterpillars are eating their way through our plant's leaves riddling them with holes. Parasitism is when one organism depends on or lives on another organism and harms or kills the other organism without benefiting it. Different caterpillars harms plants more than others but they all feed on plant leaves in groups eating through the leaves leaving significant damage and in some cases if not controlled will kill the plant.

Both Primary and Secondary Succession is occurring in in the garden. Primary Succession is going on the rock around the garden because there is lichen growing on the surface creating the start of soil. Secondary Succession is happening in the barren garden beds where past projects that have died from previous years once grew. I know this because there is already soil in the bed and an ecosystem is starting to be created because there are patches of weeds starting to grow with insects in the area too.

Blog Post #8- A Matter of Selection (Colin McCombs)

W hile studying our   Brassica oleracea plants in the   WGHS GOLD Main Garden me and my team discovered and observed a lot about the plants. We found that the shape size and texture of the different plants varied in the garden the most. Some of the plants had smooth thick ruffled leaves, some had hairy ruffled leaves ,and some had hairy flat leaves. All of the leaves also varied in size along with texture and collected this data by observing and taking measurements from the Brassica oleracea in the garden.  This is a picture of the plant #1 leaf. From the picture you can see that this leaf is very smooth and thick and doesn't have any hairs or spines. It is a lighter green color with a blue hue and is very ruffled especially around the plant leaves edges. We measured the length of this leaf and it came in at 13.3 cm which is bigger than some of the plants but not as big as the ones you will see later. This is a picture of the plant #2 leaf. This leaf is very ...

1) My groups plant has been getting larger and growing over the course of the past few months. It has been preforming the process of photosynthesis to add biomass and the amount of resources available to the plant. Photosynthesis is one of the main ways a plant comes to thrive in it's environment, this is when plants take sunlight to convert CO2 into O2 and high energy sugar. Despite the fact that it's winter right now and the sun isn't out as much, our plants have still been able to take the available light energy and use it in photosynthesis. Another big process that is occurring to allow our plants to grow is known as Mitosis. Mitosis is the replication and division of cells inside a living organism to allow that organism to grow and stay healthy. Mitosis is also vital to allowing space for new cells to take up a spot in the organism, as the organisms grow and mature they'll need more cells to keep up with the rapid advances in size and functions. This is made especi...

Fertilization occurs in flowering plants through the process of fertilization. The center of the flower has long thin filaments with anthers at the top. This is called the stamen. Four pollen sacks are located in the plants anthers which contain MMCs, Micro Mother Cells. Each of the pollen sacks produces eight pollen grains, the sperm cells from the MMC. Once the pollen grains inside each of the sacks are ready the anthers will burst open vomiting the sticky pollen onto the flowers stamen in a process called dehiscence. The flowers bright colorful pedals lure insects inside to drink its nectar, located at the flowers base. Once the insects climb into the flower the sticky pollen from the anthers gets stuck on its feet, legs, or body. In the process of cross pollination the insect that collects this sticky pollen will transfer it to another flower pollinating it in the process. In the process of self pollination the pollen will be moved from the stamen to the pistol/carpal of the flowe...
