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…
Plant Cell Science Project
The following sample plant cell science project experiment is meant to give you ideas on how to perform experiments and arrange your project. Use this project to come up with ideas for your own experiments.

Plant and Animal Cells
The objective of this lab was to learn what a microscope reveals about plant and animal cells. The completion of this lab should teach the participant the differences between plant and animal cells and how to examine samples of the covering tissues of a plant (the onion) and of an animal (the participant) using the epidermis and cells from a cheek swab of epithelial tissue.

Animal and Plant cells
Most cells have some structures in common. They have:
A nucleus to control the cell’s activities
Cytoplasm where many chemical reactions take place
A cell membrane that controls the movement of materials in and out of the cell
Mitochondria where energy is released during aerobic respiration
Ribosome’s are present where protein synthesis takes place
Plant and algal cells also have:
A rigid cell wall made of cellulose for support…

Is this cell a Prokaryote or a Eukaryote cell? (Eukaryotoe cell)
All animal cells are made up of many cells Some animals, like humans, have trliions of cells, while others, like bacteria are made of just cell.
Cells are like little societies in which each orginal performs a Differnet job.

The Nucleolus ( Both Plant and Animal )
The Nucleolus is a structure found inside the nucleus inside an animal cell. It forms around
chromosomal areas in the nucleus of eukaryotic cells and is made up of proteins and ribonucleic
acids. The function of the nucleolus is to create RNA and combine it with proteins to form
incomplete ribosomes. The nucleolus takes up about 25% of the volume of the cell nucleus…
Cells are the basic unit of life and often combine with other cells to form tissues.
3. The image above is of a plant cell. You can tell by the shape of the cell. Plant cells tend to be rectangular shaped while animal cells are circular. Plant cells have a cell wall and have a large central vacuole.
5&7. In the cell cycle, the cell grows and prepares for cell division. The cell is in interphase when it is preparing for division. Cell division involves the splitting of the nucleus…
