Looking Inside Cells
Identifiy the definition of cells parts and their functions
| Question | Answer |
|---|---|
| What is an organelle? | An organelle are tiny structures inside of cells that carry out specific functions in a cell such as producing energy , build and transport needed materials, and store and recycle wastes. |
| Does a cell wall produce energy , build and transport needed materials , and store and recycle cells? | No, it doesn't. A cell wall is a rigid layer of non-living material that surrounds PLANT cells . It helps protect and support the cell, but it's stiff and many materials can pass through it |
| What is a nucleus? | The nucleus is a large, oval structure that acts as the brain of the cell. |
| What's a cell membrane? | It's the outside boundary that separates the cell from its environment and its main function is to control what substances come into and out of a cell |
| What is chromatin and what is its function? | Chromatin is thin strands in the nucleus , which contains genetic material, and it gives instructions for cell function |
| What's Cytoplasm? | It's the region between the cell membrane and the nucleus, and many cell organelles are found here. |
| What is Mitochondria? | Rod- shaped organelles that produce energy. |
| What's the Endoplasmic Reticulum? | A maze of passageways that carries proteins and other materials from one part of the cell to another. |
| What are ribosomes? | Grainlike bodies that also produce proteins. |
| What are Golgi Bodies? | Collections of sacs and tubes that distribute proteins and other materials throughout the cell. |
| What are Chloroplasts? | In plants and some other organisms, they're large , green structures that captures energy from the sunlight and uses it to produce food for the cell. |
| What are vacuoles? | A large sac that stores food and other materials in the cell. |
| What are lymosomes? | Small , round structures that break down food and recycle old cell parts. |
| What are organisms whose cells lack a nucleus ? | Prokarotes |
| Those cells who have a nucleus are...? | Eukaryotes |
| Section 2 Chemical Compounds in Cells | |
| What is any substance that cannot be broken down into similar substances? | An Element |
| What's the smallest unit of an element? | An Atom |
| What forms a compound? | When two or more elements combine chemically. |
| A molecule is...? | The smallest units of compounds |
| What is a organic compound and what does it include? | A compound that contains carbon. They include carbohydrates, lipids, proteins, and nucleic acids. |
| What's a carbohydrate and what is it made up of? | A carbohydrate is an energy-rich organic compound made of the elements carbon , hydrogen , and oxygen and in some cases , sulfur. |
| What are amino acids? | Proteins molecules that are made up of smaller molecules. |
| What is a type of protein that speeds up a chemical reaction in a living? | An enzyme. |
| What lipids and what are some examples? | Lipids are energy-rich organic compounds made of carbon , hydrogen, and oxygen. Some examples are fat , oils, and waxes. |
| What are very large organic molecules made up of oxygen, hydrogen, nitrogen , and phosphourus. | Nucleic Acids. |
| What type of nucleic acids is passed from parent to offspring and provides directions for coding | DNA , Deoxribonucleic |
| What type of nucleic acid carries , transmit , and transfers directions from the DNA | RNA |
