This power point presentation consists of 64 slides including information about plant and other type of cell wall. Most eukaryotic cells have three main components: The Structure and Function of the following organelles will be discussed: Structure: phospholipid bilayer with proteins that function as channels, markers, and receptors, Function: selectively permeable boundary between the cell and the external environment, Structure: the nucleus is a sphere that contains another sphere called a nucleolus, Structure: rigid wall made up of cellulose, proteins, and carbohydrates, Function: boundary around the plant cell outside of the cell membrane that provides structure and support, Structure: gelatin-like fluid that lies inside the cell membrane, Function: -contains salts, minerals and organic molecules, Structure: a network of thin, fibrous elements made up of microtubules (hollow tubes) and microfilaments (threads made out of actin), Function: -acts as a support system for organelles, Structure: consist of two subunits made of protein and RNA, Structure: a system of membranous tubules and sacs, Function: intercellular highway (a path along which molecules move from one part of the cell to another), Rough Endoplasmic Reticulum (rER): prominent in cells that make large amounts of proteins to be exported from the cell or inserted into the cell membrane, Smooth Endoplasmic Reticulum (sER): involved in the synthesis of lipids and breakdown of toxic substances, Function: receives proteins from the rER and distributes them to other organelles or out of the cell, Structure: folded membrane within an outer membrane, The folds of the inner membrane are called cristae, Function: -converts energy stored in food into usable energy for work, Structure: spherical organelles that contain hydrolytic enzymes within single membranes, Function: breaks down food particles, invading objects, or worn out cell parts, Structure: spherical organelles that contain enzymes within single membranes. Some organisms consist of a single cells = unicellular organism, others are . However, animals and protozoans do not have this type of structure.
