| cell | the basic unit of all living things |
| cell membrane | the cell part that gives the cell shape and holds the cytoplasm |
| cellular respiration | the process by which food is broken down and energy is released |
| cell wall | the thick, outer covering outside the cell membrane |
| chloroplast | cell parts that contain the green pigment, chlorophyll |
| chromosome | cell parts with information that determines what traits a living thing will have |
| cytoplasm | the clear, jellylike material between the cell membrane and the nucleus that makes up most of the cell |
| diffusion | the movement of a substance from where there is a large amount of it to where there is a small amount of it |
| mitochondria | cell parts that produce energy from food that has been digested |
| nuclear membrane | a structure that surrounds the nucleus and separates it from the rest of the cell |
| nucleolus | the cell part that helps make ribosomes |
| nucleus | the cell part that controls most of the cell's activities |
| organ | a group of tissue that work together to do a job |
| organism | a living thing |
| organ system | a group of organs that work together to do a certain job |
| osmosis | the movement of water across the cell membrane |
| producer | a living thing that makes, or produces, its own food |
| tissue | a group of similar cells that work together to carry out a special job |
| vacuole | a liquid-filled space that stores food, water, and minerals |
| prokaryote | type of cells that lack a nucleus & most organelles, such as bacteria |
| eukaryote | type of cells that have a nucleus, such as plants & animals |
| active transport | movement of materials from low to high concentration, requires cell energy |
| passive transport | movement of materials from high to low concentration, requires no cell energy |
| ribosome | part of cell that makes protein |
| Endoplasmic reticulum | parts of cell that transports materials around cell |
| Golgi bodies | parts of cell that package materials |
| nucleolus | found inside nucleus, makes ribosomes |
| nuclear membrane | surrounds the nucleus, controls what enters nucleus |
| centrioles | parts found only in animal cells, help cells divide |
| lysososome | cell parts that contain enzymes to digest materials |
| cytoskeleton | includes microfilaments & microtubules, help with cell support & movement |
| facilitated diffusion | passive transport where protein molecules help molecules pass through membrane, making it EASIER |
