Cell Theory
|
-all living things are made up of cells
-cells are the smallest unit of life -all cells come from other cells |
|
|
What are the two types of cells?
|
Prokaryotic and Eukaryotic
|
|
|
Cell
|
Smallest unit of life that is capable of carrying out life functions
|
|
|
Prokaryotic cells
|
-do not have structures
-surrounded by membranes -few internal structures -usually in 1-celled organisms. |
|
|
Eukaryotic cells
|
-contain organelles surrounded by membranes
-in most living organisms |
|
|
Cell Membrane
|
controls passage of material in cell
only lets certain members in cell |
|
|
Nucleus
|
-control center of the cell
-contains DNA code coiled into chromosomes |
|
|
Cytoplasm
|
Where the organelles live
|
|
|
Mitochondria
|
-processes energy for the cell.
-involved in cellular respiration -uses ATP |
|
|
Body(of cell)
|
- contains protein
-packaging transport center of cell |
|
|
Ribosomes
|
-synthesizes proteins
-present in cytoplasm -present within endoplasmic reticulum -no membrane present |
|
|
Endoplasmic Reticulum
|
-covered with ribosomes
-produces protein --transports materials throughout cell |
|
|
Lysosome
|
-breaks down material for digestion
-contains enzymes for digestion cell breaks down if this explodes |
|
|
Chloroplast
|
-contains chlorophyll
-makes plant green -found in plant cell -uses sunlight to make ATP (energy) and sugars |
|
|
Golgi Apparatus
|
-Modify proteins made by the cells
-Package & export proteins |
|
|
Vacuole
|
-Stores food,water, and toxic wastes
-Store large amounts of food or sugars in plants |
|
|
heterotrophic
|
organisms that can't make their own food
|
|
|
autotrophic
|
organisms that can make their own food
|
|
|
what organelles are only found in animal cells?
|
centrioles & lysosomes
|
|
|
what organelles are only found in plant cells?
|
Cell wall and chloroplasts
|
|
|
name levels of organization from smallest to largest
|
cell-----tissue------organ------organ system-----organism
|
|
|
who discovered the cell?
|
Robert Hook
