Cell |
Basic unit of life |
|
|
Cell Theory |
1) All living things made of cells 2) Cells are basic unit of function and structure in living things 3) Cells come from existing cells |
|
|
Nucleus |
Large membrane-enclosed structure that contains the cell’s genetic material |
|
|
Eukaryote |
Cells that contain nuclei and membrane bound organelles |
|
|
Prokaryotes |
Cells that don’t contain nuclei or membrane bound organelles |
|
|
Organelles |
Smaller parts of a larger cell that have specialized functions |
|
|
Cytoplasm |
The portion of the cell located outside of the nucleus |
|
|
Nuclear Envelope |
The double membrane protecting and surrounding the nucleus |
|
|
Chromatin |
The granular material inside of the nucleus |
|
|
Chromosomes |
During cell division, the chromatin in the nucleus condensed into these |
|
|
Nucleolus |
The small, dense region inside the nucleus. Where the assembly of ribosomes begins. |
|
|
Ribosomes |
Small particles of RNA and proteins that focus on protein synthesis |
|
|
Endoplasmic Reticulum |
Internal membrane system where the lipid components of the cell membrane are assembled. |
|
|
Golgi Apparatus |
Modifies, sorts, and packages proteins and other materials from the ER for storage in the cell or secretion outside of the cell. |
|
|
Lysosomes |
Small organelles that are filled with enzymes. They breakdown molecules so they can be used by the cell or secreted outside the cell. |
|
|
Vacuoles |
Saclike structures that provide storage inside of the cell |
|
|
Mitochondria |
Converts chemical energy stored in foods into compounds that can be used by the cell. Major source of energy for the cell. |
|
|
Chloroplasts |
Organelles that capture sunlight and convert it into chemical energy during photosynthesis. |
|
|
Cytoskeleton |
Internal organization of tubules and filaments that support the shape of cells. |
|
|
Centrioles |
Near the nucleus and helps organize cell division. |
