Name: Date: Hour: Mrs. Zajaczkowski.............Biology…….… The Internal Environment of Organisms Cell Organelle Chart Organelle Cell membrane Cytoplasm Nucleus Ribosomes Chromatin Found B, P, A Structure Made of fat and protein molecules Constantly moving and fluid-like because it’s made of liquid fats (unsaturated) Jellylike fluid that is mainly made of water. Round and surrounded by a membrane that protects DNA and lets messages go in and out of the nucleus. Acts as a filter and passageway for things moving in and out of the cell. Goal – Keep the bad stuff out, let the good stuff in. B, A. P A, P B, A, P B, A, p Consists of RNA and proteins The smallest organelles. Look like snowmen Consists of DNA bound to proteins When cell is ready to divide, chramatin condenses into chromosomes Endoplasmic reticulum Function A, P A series of interconnecting tubes around the nucleus. Rough ER (RER) has ribosomes. Smooth ER (SER) has no ribosomes. Suspends and supports the cell’s organelles Place where many of the cells most important chemical activities occur. Manages cell functions; the DNA inside the nucleus is the instruction manual for the cells’ activities. Without the nucleus the cell will be unable to create new cells and will eventually die. DNA RNA amino acids proteins Instructions, messenger, building blocks These proteins are used in your cells’ membranes for building muscles, creating blood cells, enzymes, etc. Contains genetic information that is passes from one generation to the next RER- Helps the ribosomes finish making the proteins. SER- makes molecules of fat (LIPID) to be used in the cells membranes and throughout the body. Golgi apparatus Lysosome Mitochondria Cytoskeleton Vacuoles Chloroplasts Cell wall A, P A series of flattened membranes with vesicles extending from all sides usually near cell membrane. Contains several different enzymes similar to enzymes in digestive systems. Breaks down material from damaged organelles, some food molecules and any toxic substance in the cell. Has a highly folded inner membrane that surrounds a fluid called the matrix. The place where the energy stored in glucose molecules is finally released so it can be used to power all the cell’s functions. Takes proteins and fats made by SER and RER and stores packages and sends them whenever needed. The cell’s own UPS service (what can Golgi do for you?) A A,P A, B, P Comes in 3 different shapes -like pasta- and is made of protein. Like a freeway system used to relay messages throughout the cell. Gives support to the cell and its organelles and assists in cell division. Contains water, food, waste, and/or pigments A storage bin for the cell It stores water and/ or pigments. Has internal membrane structure that looks like stacks of pancakes Place where photosynthesis occurs. When energy from the sun is used to make glucose. Made of carbohydrates Has large holes throughout its surface Provides structure, shape, and stability for the plant, It’s like a skeletal system for the plat. Because of the holes in its surface it lets most things pass through it. Even things harmful to the cell. A, P P P
