Julia Babin Ms. Bukola 11/6/2012 Bio Lab W 8 Cell Structure and Function Prokaryotic cells do not contain a nucleus. Eukaryotic cells do contain a nucleus. Organisms are eukaryotic except Bacteria and Achaea. Organelles are small membranous bodies‚ each with a specific structure and function. Prokaryotes do have cytoplasm‚ which is the material bounded by a plasma membrane and cell wall. This contains ribosomes‚ small granules that coordinate the synthesis of proteins

Cell Organelle Worksheet Organelle Nucleus Where found (plant/animal/both) In animals it’s in the center of the cell while in plants it’s found in the cytoplasm. What it does in the cell (functions) It maintains the integrity of the genes and controls the activities of the cell. Something that performs the same function in the “real world” It works like a CPU sending out messages. Organelle Nucleolus Where found (plant/animal/both) For both animal and plants it’s within the nucleus of the

The cell wall is the tough‚ flexible but sometimes fairly rigid layer that surrounds some types of cells. It is located outside the cell membrane and provides these cells with structural support and protection. Just as the wall of the factory is for the factory. The wall also is the structure and strength. The cell membrane that separates the interior of all cells from the outside The cell membrane is selectively permeable to ions and organic molecules and controls the movement of substances

background knowledge relating to the current cell theory‚ the differences between prokaryotes and eukaryotes‚ and the structures and functions found within cells. Once this knowledge is known‚ a person is then able to give their opinion in the debate. In the 1800s‚ the cell theory was developed. This theory states that cells are found in all living things making them the basic units of life and that all cells come from other cells. In order to be classified as a cell‚ the object in question must be able

The Cell Theory The Cell Theory‚ formed by Anton van Leeuwenhoek‚ Robert Hooke‚ Matthias Schleiden‚ Theodore Schwann‚ and Rudolf Virchow‚ refers to the idea that cells are the basic unit of structure in every living organism. The theory justifies three principles: all living organisms are composed of one or more cells; the cell is the most basic unit of structure‚ function‚ and organization in all organisms; and all cells come from pre-existing‚ living cells. The formation of the cell theory

A Cell Compared to a Hospital Cameron Browne The main organelle is the nucleus. I think the nucleus is like the hospital administration because the nucleus is the core of the cell that handles everything‚ and the hospital administration handles everything that goes on in the hospital. Without the “cores” for both the hospital and the cell‚ neither could properly functions. The nucleolus is the center of the nucleus‚ and it basically sends out all of the other organelles that work within the

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

the size of cheek cell and onion cell DCP: Introduction: In this experiment‚ Onion cells (Allium cepa) Cheek cells (Homo sapiens) were measured and compared. The aim of this experiment is to find out how both cells differ by comparing their size. Onion cells (Allium cepa) is plant cell and Cheek cells (Homo sapiens) is an animal cell. Hypothesis: The size of an animal cell (Homo sapiens) should be smaller than a plant cell (Allium cepa). Because a plant cell has cell wall which is to maintain
