Features of Life and the Cell

1. Reproduce: To form offspring similar to the parents.
2. Development: All the changes that occur as a living thing grows.


3. Consumers: Living things that eat, or consume , other living things.

4. Producers: Living that make, or produce their own food

5. Cellular respiration: the process by which food is broken down and energy is released.

6. Cell: The basic unit of all living thing.

7. Adaptation: a trait that makes a living thing betterable to survive.


8. Cell Membrane: the cell part that gives the cell shape and holds the cytoplasm.
                                           

9. Nucleus: the cell part that controls most of the cell´s activities.

11. Nucleolus: the cell part that helps makes ribosomes.
                                    
12. Chromosome: cell parts with information that determines what traits a living thing will have.
                                          
13. Cytoplasm: the clear; jellylikematerial between the cell membrane and the nucleus that makes up most of the cell.
                                          
14. Ribosome: cell parts where proteins are made.
                                  
15. Mitochondria: cells parts that produce energy from food that has been digested.
                                         
                                           
                                         
16. Vacuole: a liquid-filled space that stores food,water, and minerals.
                             
17. Centrioles: cell parts that help with cell reproduction.
                                     
 
18. Chloroplast: cell parts that contain the green pigment, chlorophyll.
                                   
19. Cell Wall: the thick, outer covering outside the cell membrane.
                                    
20. Diffusion: the movement of a subtance from where there is a large amount of it.
                                 
21. Osmosis: the movement of water across the cell  membrane.
                               
22. Tissue: a group of similar cells that work together to carry out a special job.
                                    
23. Organ: a group of tissues that work together to do a job.

                                       
24. Organ System: a group of organs that work together to do a certain job.
                                    
25. Organism: A living thing.
