Cellular Structure and Function
Biology I Factoids
Factoid #41
• Prokaryotic cells have no nucleus and include bacteria.
Factoid #42
• Eukaryotic cells have a nucleus.
Factoid #43
• The nucleus controls the cells activities and is where the DNA is located.
Factoid #44
• The endoplasmic reticulum transports substances throughout the cell.
Factoid #45
• Rough ER has ribosomes attached to it and smooth ER doesn’t have ribosomes attached.
Factoid #46
• The Golgi apparatus is the packaging center of the cell and looks like a stack of sacks.
Factoid #47
• The vacuole stores substances. It is LARGE in plants, but tiny or non-existent in animals.
Factoid #48
• The mitochondria is the site of cellular respiration and is called the powerhouse of the cell.
Factoid #49
• Chloroplasts are the site of photosynthesis and converts water and carbon dioxide into oxygen and high energy sugars.
Factoid #50
• The nucleolus is the dark spot inside the nucleus that makes ribosomes.
Factoid #51
• The cell membrane is made up of phosopholipids and separates the inside of the cell from the outside of the cell.
Factoid 52
• The cell wall is made up of carbohydrates and only found in producer cells.
Factoid 53
• The cytoplasm is the jelly-like interior of the cell where the organelles are found.
Factoid 54
• Ribosomes make proteins.
Factoid 55
• The cytoskeleton is a network of thin protein fibers that help the cell keep its shape and helps the cell move.
Factoid 56
• Plant cells have large vacuoles, chloroplasts, and cell walls, but animal cells do not.
Factoid 57
• Animal cells have lysosomes, centrioles and small vacuoles, but plant cells do not.
Factoid 58
• A group of cells working together for a common purpose is called a tissue.
Factoid 59
• The four tissue types are epithelial, muscular, connective, and nervous.
Factoid 60
• A group of tissues working together for a common purpose is called an organ.
Factoid 61
• The heart, brain, lungs, and stomach are all examples of organs.
Factoid 62
• A group of organs that work together for a common goal is called an organ system.
Factoid 63
• The 11 body systems are:
Muscular, skeletal, digestive, respiratory, nervous, excretory, endocrine, reproductive, integumentary system, lymphatic system, and the cardiovascular system.
Factoid 64
• A group of organs systems that work together is called an organism.
