Eukaryotes have organelles because it has to carry out so many complicated activities to do in the body. One example of an organelle is the endoplasmic reticulum. The ER is a series of membranes extending throughout the cytoplasm of eukaryotic cells. The rough endoplasmic reticulum has ribosomes. The rough ER is the location

Just like Disneyland‚ inside the entrance gates are all the attractions and entertainments. Next‚ we can talk about the cilia and flagella of the cell. This organelle helps propel the cell into action. This kind of

The Nucleus: In the kingdom the nucleus is the king. The nucleus is a membrane-bound organelle found in the center of the cell that contains all of the genetic information‚ and DNA and controls the rest of the cell. To the kingdom the nucleus is the king because of how he controls the kingdom and is responsible for the wealth of the town through his actions. Additionally not all cells have a nucleus. Just as not all kingdoms have a king. The Nuclear Envelope: The nuclear envelope is similar to

The nucleus is the largest and most prominent organelle‚ occupying about 10% of the total volume of a cell and can have a varying number of nuclei. It could be uni-nucleate – single nucleus; bi-nucleate – two nuclei or even multi-nucleate. The nucleus separates itself from the surrounding cytoplasm by the double membrane around it called the nuclear envelope‚ this helps to regulate the flow of certain substances going in and out of the nucleus. At varying points around the nucleus‚ the two membranes

thing that can be alive‚ and all living things are made of cells! Cells are made of tiny organelles that work together to help the cells live‚ just like organs in our body keep us alive. You must also remember that there are two types of cells. Eukaryotic and Prokaryotic. The differences are simple; Eukaryotic cells are more complex and have more organelles while Prokaryotic cells are simple and have little organelles. Also‚ Eukaryotes (eukaryotic cells) have one or more cells while Prokaryotes (prokaryotic

a) Using a human cell of your choice‚ describe how organelles work together to make and secrete a protein (LO1. AC 1.1) An epithelial cell in the thyroid gland‚ called a thyrocyte forms spherical follicles that produce a protein called thyroglobulin. This is a globular protein that has a functional role in metabolism. The protein is used by the thyroid gland to produce thyroid hormones; thyroxine (T4) is an example of one of the hormones created. Thyroxine is formed by iodine binding to tyrosine

Playdough to create a plant and an animal cell. Students will use several different colors to make the organelles for each cell. This activity could be incorporated into a unit on cell structure and function. The organelles for both cells will be color coded to help identify the structures. Along with colors‚ each organelle will have a specific shape. The shapes will resemble that of the actual organelle. A cell diagram will be given to each student to use throughout the activity. Prepare each lab

Caroline Moore How to identify the organelle: The cytoplasm lies directly outside the nucleus‚ filling up the “empty space” outside of the Nucleus- (the pink sphere in the middle of the cell in the diagram on the right). Function of the organelle in an animal cell: Cytoplasm is the jelly-like part of the cell. It is where the nutrients are used. It is used to provide support for the other organelles in the cell like the nucleus and cytoskeleton. The cytoplasm
