Transcript of Mrs. Beck's 7th Grade Science Project

Cell Wall Ribosomes are in the cells central cytoplasm. The ribosomes main function is arranging strands of amino acids for use. If you want to COMPARE a ribosome in everyday life you'd compare it to cereal. Because the cereal floats on the milk just like the ribosome floats on the cytoplasm. One of the many organelles is ribosomes. The cytoplasm is where pretty much all the work is done. Nutrients are absorbed, transported, and processed within the cytoplasm. Plants and Animal Cells
Katelyn Vallejo Cells are everywhere. They are in every living thing. Plant cells are a eukaryote cell. Meaning they contain more than once cell. Mrs. Beck 6th Period Cytoplasm Endoplasmic Reticulum The endoplasmic reticulum has two parts. The rough ER has many ribosomes lining it's inside. The rough ER makes things for the cell to use or send to other cells. The smooth ER's job is to remove toxins from the system. So in other words, it takes bad stuff out of the body. The cell wall helps protect the body from foreign objects. It also takes in nutrients for the cell. It only allows certain things to come into the cell, let's waste out, and keeps the foreign objects out. Chloroplasts Chloroplast is only found in plant cells. Chloroplasts also gives plants their green color. The Nucleus The nucleus is the "control center" or the "brain" of the cell. It's a eukaryotic cell. It stores genetic information of the organism. It also controls other cell activity. Lysosomes: Lysosomes are membrane enclosed organelles. they function as a digestive system. They're main use is for digestion. They are like the clean up crew of the cell. Vacuoles: Vacoules are found in plant cells. They are used for temporary storage or some material. Other functions include removing unwanted debris and isolating materials that might be harmful to the cell. Compare a vacuole to a storage house. Because it stores all the water and waste in the cell. Cell Membrane The Cell Membrane is like a barrier. It helps maintain the shape of the cell. But that's not it's major function. It protects substances. I would compare a Cell Membrane to a security alarm. It can't go through the Cell Membrane. The Mitocondria: The Mitocondria is known as the "powerhouse" of the cell. It provides and generates the energy of the cell. It has many, many other smaller roles/functions. They are found in most eukaryotic cells. Think of a grocery store. The Mitocondria would be the money. Because it keeps the store(cell) going. Golgi Body: The Golgi Body stores, packages, and distributes proteins. The proteins are made in the Endoplasmic Reticulum. That's the main function. And that's all you really need to know. The most simple explanation is it packages proteins and sends it to other parts of the cell. I'd compare it to a bagging station at the grocery store. -Golgi Body -Cytoplasm(lighter green) -Endoplasmic Reticulum -Vacuole -Cell Membrane -Cell Wall -Lysosomes -Nucleus -Mitocondria -Ribosomes -Chloroplasts
