Term | Definition |
Six Characteristics of living things | * maintain homeostasis
*respond
* require energy
*grow and develop
*can reproduce
*have one or more cells |
Homeostasis | Maintain a stable internal invironment |
Cell Theory | 1)All organisoms are made of one or more cells
2)a cell is the smallest living thing
3)All new cells come from pre-existings cells |
The four things all cells have | *DNA *CELL MEMBRANE *CYTOPLASM *RIBOSOMES |
Selectively Permeable | Some things can go through and some things can go out. |
The Cell Membrane allows this in? | nutrients-water-O2 |
Diffusion | The movement of particles from an area of low concentration to high concentration |
cell membrane | Selectively Permeable |
Ribosomes | It provides protien |
Golgi body | Packages molecules that are ready to be sent out |
Lysosomes | They clean the cell they are like the janitors |
Cell Wall | It protects the cell |
mitochondria | Transforms energy that's in food into energy the cell can use |
central vacuole | stores food, water, and waste products |
The Rough ER | this is where proteins are made. It transports things through the cell |
The Smooth ER | It detoxifies harmful substances that enter the cell. |
chloroplast | Demonstrates photosynthesis |
cytoplasm | Contains nutrients and holds the organelles in place |
nucleus | Gives instructions to the cell |
Prokaryotic Cell | less complex,smaller, bacteria is made of this cell, first living organism on the planet. |
Eukaryotic Cell | More complex, Animals and plant's are made of this, has organelles,DNA is found in the nucleus. |
This transports materials within and without the cell | water |
The three unique things about plant cells are this | These are the three things that are unique about plant cells, they have chloroplast, they have a central vacuole, and they have a cell wall. |
