Looking Inside Cells

Identifiy the definition of cells parts and their functions

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
