More Questions #4 Who used drops of lake water, scrapings from teeth and gums, and water from gutters for scientific observation? #5 What are cells? #6 True or False, chromatin are genetic material in the nucleus that controls what goes in and what goes out. ___ 3 Times up! It was Anton van Leeuwenhoek Cells are the basic units of structure and function in living things. False! Chromatin are genetic material in the nucleus that controls the activities of the cell.

Ready for more? #7 What is the dense area in a eukaryotic cell that contains nucleic acids, the chemical instructions that direct the cell’s activities? #8 What is the vacuole? #9 Next question. What is the instrument that makes small things look large? ____ 3 What is the nucleus! A sac inside a cell that acts as a storage area. The microscope!

Are you flexing your brain muscles? # 10 A Microscope that uses a beam of electrons instead of light to produce a magnified image is called a(n) ________ microscope. #11 What are the 3 points of cell theory? #12 Cytoplasm is… ____ 3 Electron goes in that blank! (A) All living things are composed of cells (B) Cells are the basics structure & function in living things (C) All cells are produced from other cells. The region between the cell membrane and the nucleus; in organisms without a nucleus, the region located inside the cell membrane.

#13 What are made in the nucleolus? You’re almost there! #13 What are made in the nucleolus? Ribosomes #14 Deal or No Deal? Golgi Bodies are a structure in a cell that receives proteins and other newly formed materials from the endoplasmic reticulum, packages them, and distributes them to other parts of the cell. It’s a deal! #15 What protects the nucleus materials pass in and out of the nucleus through pores in the envelope? The Nuclear Membrane! #16 Mitochondria are… Rod-shaped cell structures that convert energy in food molecules to energy the cell can use to carry out its functions. ___ 4

#27 Endoplasmic Reticulum (ER) is adjacent to what part of a cell? The Nucleus #28 Describe the ER. A cell structure that forms a maze of passageways in which proteins and other materials are carried from one part of a cell to another. #29 What part of the microscope adjusts the amount of light? diaphragm #30 When talking about a lens, what does resolution mean? Resolution is the sharpness of an image Extra credit! What did Hooke put under his microscope when he used it for the first time? Cork Score your self How did you do?
