FC: Cellular Organelles
1: Structure & Function Of Organelles By: Bianca N.
2: Cell Membrane
3: What's a Cell Membrane? The Cell Membrane is the outer layer of protection of a cell. It is very important because it protects the cell from the environment. | function: It controls the movement of materials into and out of the cell. It is semi-permeable, so water can move into and out of the cell. Nutrient particles and gas exchange occur where some molecules enter and waste products leave through the cell membrane.
5: What is it? Mitochondria are the power producers of a cell. | What is their function? They convert the chemical energy stored in food into compounds that are more convenient for the cell`s use.
6: Plant Cell Wall
7: What is it? It is a strong supporting layer around the cell membrane. Animal cells do not have cell walls. | Its Function... is to support, shape, and protect the cells. Most cell walls are porous to allow water, oxygen, carbon dioxide, and other substances to pass through easily.
9: What is it and where is located? Chloroplast are located within any plant ells the are able to conduct photosynthesis. If a structure on a plant is green, then it contains chloroplast. It is a placid that contains chlorophyll. | Function: Its function is to oxidize carbon dioxide and glucose when light is present to create water and oxygen. This process of making their own food is call photosynthesis.
11: What is it? threadlike structure of DNA and protein that contains genetic information; in eukaryotes, chromosomes are found in the nucleus; in prokaryotes, they are found in the cytoplasm. | Function Chromosomes carry portions of the hereditary information of an organism. They are considered the building blocks of the human body. Chromosomes functions are based on the precise structure of the organelle that carries out that function.
13: Structure: The nucleus is surrounded by a nuclear envelope composed of two membranes. The nuclear envelope is dotted with thousands of nuclear pores, which allow material to move into and out of the nucleus. A steady stream of proteins, RNA, and other molecules move through the nuclear pores to and from the rest of the cell. | Function: The nucleus is the center control of a cell. It contains nearly all the cell`s DNA and, with it, the coded instructions for making proteins and other important molecules.
14: Structure Of Ribosomes
15: What is it? Ribosomes are small particles of RNA and protein found throughout the cytoplasm in all cells. | Function: Proteins are assembled in ribosomes. Ribosomes produce proteins by following coded instructions that come from DNA. Ribosomes turn out proteins on orders that come from its DNA. Cells that are especially active in protein synthesis often contain large numbers of ribosomes.
17: What is it? Vacuoles are large, saclike, membrane- enclosed structures in a cell. | ITS Function: Vacuoles store materials like water, salts, proteins, and carbohydrates.

23: "I believe a leaf of grass is no less than the journey work of the stars." | Walt Whitman
