Hey little guy they call me the nucleus of an animal cell and lucky you I’m going to be your mentor and I’m going to teach you about me. So welcome as a new Ribosome organelle in the cell world‚ I’m going to make you familiar with your new home. We are going to start off with the Cell Membrane. The Cell Membrane is the selective barrier that’s surrounding the cell. Since you’re a newbie you need to know that the cell membrane allows only certain things to pass into it‚ but that’s only if it’s made

to start class today talking about cells. Believe it or not‚ each and every one of you came in contact with cells over the weekend. The most important thing to remember is this: cells make up living things. They make up us‚ our families‚ our dogs‚ and even the trees that provide shade to your front yard. Today we are going to focus on the cells that make up our bodies. Your skin‚ brain‚ muscles‚ bones‚ and every other part of your body is made up of cells. Cells are the basic building blocks of all

Chapter-8 Cell: The Unit Of Life What is a cell? Cell is the basic or fundamental structural and functional unit of an organism. What is cell biology? The branch of biology that deals with the study of cell structure and function is called cell biology. DISCOVERIES; Who discovered cell? Robert Hooke observed a live cell in 1665. He observed the cell(actually the cell walls) in the slice of cork under his compound microscope ‚coined the term cell‚ recorded his observations in micrographic

Animal Cell Cells are the beginning of everything. Every living thing is composed and made from cells. Cells are the smallest unit of organization that we know of. There are two major categories of cellular organization in eukaryotic cells. Those parts which are “membrane bound”‚ called organelles and those which are not “membrane bound”. Every aspect of the cell is important because each part or organelle’s structure is unique to its function. Non membrane bound organelles‚ are those which provide

ANIMAL CELL PROJECT By: Jonathan Everett Science 2nd Ms. Thompson January 11‚ 2013 Have you ever heard of an animal cell? Well‚ I you haven’t it is a cell that is found in an animal that consist of multiple organelles. Each organelle has a special job that helps the cell function. This paper will help describe each organelle in the animal cell. 1. Endoplasmic Reticulum The Endoplasmic Reticulum is found in both the plant and animal

light microscope when you want to see the cell in the act of moving or dividing. 2. Prokaryotic cells don’t have organelles like eukaryotic cells do. Eukaryotic cells contain its DNA within its nucleus‚ while prokaryotic cells keep it within the nucleoid. Prokaryotic cells are also more minute than the eukaryotic cells. Also although they both contain ribosomes‚ they are composed differently. 3. The central vacuole (takes in water and chemicals)‚ cell wall (allows the plant to be strong enough

of cells and their ultra structure The cell is the basic unit of life. Each cell can be regarded as a metabolic compartment‚ a separate place where the chemical processes of that cell occur. Cells are often designed to perform a particular function. Depending on that function‚ each cell type has an internal structure that suits it for its job. This is known as the ultrastructure of the cell. There are different types of cells inside the human body. They are the epithelial cells‚ muscle cells‚ nerve

Eukaryotic Cells Cells are the basic building block of life. Cells can be either Eukaryotic or Prokaryotic cells. Organism can only contain either one but not both of them. Prokaryotic cells are usually much smaller than Eukaryotic and are less complex. Bacteria are made up of one or more prokaryotic cells. Bacteria are made up of one or more prokaryotic cells. While Eukaryotic cell are found inside plant and animal life. Eukaryotic are more advanced and larger. Prokaryotic cell were the first
