Plant Cell 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 the cell function. All plant cells have a nucleus which consists of a nucleolus, nuclear envelope and nuclear pores. The nucleus is an oval shape which contains the nucleolus and DNA. The process of DNA being altered into RNA takes place within the nucleus; the nucleolus is the site of RNA synthesis and also contains RNA and Protein. The Nuclear envelope consists of two membranes its function is to separate the content within the nucleus from outside of the cell. The nuclear pores control the passage of proteins between the cell’s cytoplasm and plasma of the nucleus. Plants contain certain organelles that animal cells do not contain which is a cell wall which is the cell wall; it functions as the structural support for the plant cell. Other organelles within the animal cell consists of a plasma membrane which is a structure that surrounds all cells, the plasma membrane separates the organelles with in the cell from the Interstitial fluid the plasma membrane also acts as a selective barrier that allows exchanges in and out of the cell. Then there is the Golgi apparatus that consists of flattened membrane stacks which…
1. Nuclear Membrane- To represent this, we used a door because the Nuclear membrane controls what goes in and out of the cell just like a door does.
2. DNA- We used this as an instruction pamphlet to represent DNA because DNA acts somewhat like instructions for the cell’s genetic material. Instructions can be found all around the home for many things such as toys, appliances, and electronics.
3. Nucleolus- We used a mother in a kitchen for this organelle because like an actual mother in a kitchen…
To begin, the outside of the cell is called the cell wall, which helps to keep the shape of the cell and acts as a protective barrier. Right inside of the cell wall is the plasma membrane, which controls the type and mass of materials that come and go out of the cell. After the plasma membrane decides what is needed the vacuole is where the material is stored. The parts responsible for the muscle of a cell is the cytoskeleton which is made up of three protein filaments, microtubules, actin filaments…
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 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…
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…
