Our idea to help protect the watersheds is to switch fertilizer to bone meal in recreational parks, playgrounds and public places during the spring time. We want to promote this by creating a campaign that not only includes information about what bone meal is, why we should switch to it and how it affects our watersheds. Bone meal is a by-product of the meat industry and is made of processed animal bones. It is a cheaper alternative in comparison to regular fertilizer and is a sustainable resource. There are both positive and negative effects when using bone meal. The watershed we are focusing on is the storm drain pond in Panorama Hills. The storm water that comes from all over the community ends up in the pond. Panorama Hills is a very recreational community; there are trails fairly close to the lake allowing you to walk your dog, most of the time they leave their dogs waste. Panorama Hills has various parks, a lot of people go to those parks and litter, and eventually their litter ends up in the pond. During the warmer months, the pond is either dried up or very murky due to the turbidity of overusing fertilizers and run off from the nearby roads. In winter time, the pond begins to freeze but the water quality is not much better. Unless there are plants inside, the rest of the pond remains black. Although bone meal includes more phosphorus than most eco-friendly fertilizers, you use less of it to get the same results. Our idea is to encourage maintenance workers to switch to bone meal in the spring time because plants absorb bone meal at a slower rate than regular fertilizers, thus using less and getting the same results. Most people use an excess of fertilizer in the spring resulting in runoff that is rich in phosphorous, nitrogen, and potassium. An abundance of phosphorus causes eutrophication in our watersheds. Eutrophication is when there is too much phosphorus in a body of water, causing the algae bloom inside to grow and die rapidly. With all the dead algae on the surface of the water, no sunlight can enter. Without sunlight in the water, it decreases the amount of dissolved oxygen in the water. Without the proper amount of dissolved oxygen in a body of water, organisms cannot survive. Since bone meal uses excess materials in the meat industry that would otherwise go to waste, therefore you’re reusing it and not producing another unnecessary product.
Organic fertilizers are formed from natural resources, such as manure, blood, and compost, as well as bone. These are all the excess products that come…
There are two classes of cells that exist in biology today, there are prokaryotic cells and there are eukaryotic cells. A prokaryotic cell is a cell that has no nucleus which consists of bacteria; a eukaryotic cell is a cell that has a nucleus. There are two types of eukaryotic cells in biology; plant and animal cells. Plant cells have organelles in each cell that helps then function and go through processes such as photosynthesis. Each cell in our body consists of organelles that help…
Both plant and animal cells are eukaryotic cells which mean they have a ‘true’ nucleus. Animal cells can come in an array of sizes and unusual shapes, unlike a plant cell which is typically rectangular or cube shaped.
What can be found in a Plant Cell and an Animal Cell?
Cell Membrane - This surrounds the cytoplasm in the cell, enclosing its contents. It is thin and semi permeable and allows substances to move through it.
Cytoplasm - a gel like substance…
Everywhere around each organelle inside the cell membrane. Protects and provides support to each organelle. It keeps the organelles supported so it is quite important.
Nucleus Quite large Circular Plant/Animal
Usually surrounded by ER Contains materials such as DNA and controls cell activities Very important because it controls the cell
Nucleolus Average Circular Plant/Animal
Inside the Nucleus Produces Ribosomes Not so important
Ribosomes Very small Little dots Plant/Animal…

Plant and Animal Cells
a. Explain that cells take in nutrients in order to grow, divide and to make needed materials. S7L2a
b. Relate cell structures (cell membrane, nucleus, cytoplasm, chloroplasts, and mitochondria) to basic cell functions. S7L2b
1. Cells are the smallest single unit that can maintain life. Within each cell are a collection of organelles that perform specific
functions. In 1855 a scientist named Rudolph Virchow consolidated the published work of other scientists and drew accurate…
between an animal and plant cell.
An animal cell doesn’t have a wall, a plant cell has a wall.
4. Know all the organelles and their function.
a. Nucleolus- Makes ribosomes. B. Mitochondria- Transform’s energy. C. Nucleus- The organelle that holds the cells genetic information. D. Vacuole- The organelle that stores waste. E. Plasma membrane- The flexible boundary between the cell and its environment that controls the amount of nutrients that can enter the cell. F. Cell wall- The rigid structure…
least in some aspects. In fact, as we now see more clearly, properties of living cells and physical laws which apply to all living and non living systems continuously interact and cannot be separated. The history of our understanding of sap ascent in plants, and especially in trees, is a beautiful example for this classical debate.

Attempts to explain water transport in plants started with a search for analogies with blood circulation in vertebrates, a physiological…
Controlling Plant Growth
After elaborate research and carrying out experimentations. I am now able to summarise what I researched and what information I have gathered. I then was able to produce two possible solutions to growing as many plants as possible in a small space.
Firstly, auxins are a type of plant growth substance, or plant hormone, with morphogen-like characteristics. Morphogens are substances that govern the pattern of tissue development (how the tissue grows) via morphogenesis…
Plants – Lecture 1, Revision question answers
Plant cells and tissues
1. a. Describe the structure of a primary cell wall. b. How does a secondary cell wall
a. The primary cell wall consists of strands of cellulose that run parallel to each other to
form the microfibrils. Various molecules including glycoprotein and pectin form crosslinks between the microfibrils.
b. Compared with the primary cell wall the secondary cell wall is thicker and more rigid.
The linking material is lignin which…
