Study Sheet
| Question | Answer |
|---|---|
| Who invented the microscope? | Robert Hook built his own microscope in 1590. He was one of the first people to observe cells. |
| What is Cell Theory? | Widely accepted explanation of the relationship between cells and living things. It says all living things are made of cells; cells are the basic units of structure/function of living things, all cells are made from other cells. |
| What are cells? | The basic units of structure and function in living things. They are known as the building blocks of life. |
| What do cells do? | Cells form the part of an organism and carry out all the processes or functions (obtaining oxygen, getting rid of waste and obtaining food). |
| What is a cell's function? | An organism's functions are the processes that enable it to stay alive and reproduce. |
| Why was the invention of the microscope important? | This made it possible for people to discover and learn about cells. |
| Why do we need microscopes? | Scientists continue to make and observe microscopes to observe things they couldn't normally see. They can learn tiny things, like cells. |
| Define structure and function. | Structure is what an object/organism is made of and how its parts are put together. Function is a process that enables an organism to stay alive and reproduce. |
| Why are cells the basic unit of structure and function in organisms? | Cells form the parts of an organism and carry out all of its functions. |
| What did Hooke see when he looked at cork under the microscope? | Hooke saw that the cork was made of many tiny rectangular spaces, which he called cells, because they reminded him of tiny rooms. |
| What are eukaryotic cells? | They have no membrane bound organelles. They are found in protozoa, fungi, plants and animals. |
| What are prokaryotic cells? | These cells contain a nucleus and organelles, and are enclosed by a plasma membrane. |
| What are organelles? | These are tiny cell structures that carry out specific functions within the cell. |
| What is cytoplasm? | A clear, thick, gel-like fluid that fills the cell. It holds the organelles in place. JELLO |
| What is a cell membrane? | A cell structure that controls which substances can enter or leave the cell. It has tiny openings called pores. GATEKEEPER |
| What is a nucleus? | A cell structure that contains the instructions that direct all of the cell's activities. BOSS |
| What is a nuclear membrane? | This protects the nucleus, and acts similar to the cell membrane. SKIN |
| What is the mitochondria? | Rod shaped cell structures that produce most of the energy needed to carry out the cell's functions. Called the "powerhouse" of the cell. |
| What is the endoplasmic reticulum? | 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. Smooth ER has no ribosomes, while rough ER has ribosomes. SUBWAY |
| What are ribosomes? | A small, grain-like structure in the cytoplasm of a cell where proteins are made. They can be attached to the ER. FACTORIES |
| What are Golgi Bodies? | A structure in the cell that receives protein and other newly formed materials from the ER, packages them and distributes them to other parts of the cell. POST OFFICE |
| What are chloroplasts? | A structure in the cells of plants that captures energy from the sunlight and uses it to produce food. SOLAR PANELS |
| What is the cell wall? | A rigid layer that surrounds the plant cell. It gives the cell a box like shape. COOKIE CUTTER |
| What is a vacuole? | A water filled sac inside a cell that acts as a storage area. They store food. A plant cell has one large vacuole. VACUUM |
