CELL MEMBRANE
Describe the cell membrane.....
A double layered structure that surrounds the cell.
Membranes are selectively permeable. Some substances can pass through it and some cannot.
List six organelles found in both plant and animal cells.
ribosomes, nucleolus, nuclear membrane, golgi complex, cytoplasm, nucleus, cell membrane, mitochondria, endoplasmic reticulum

What is the function of the mitochondria?
1) Mitochondria are the units made up of DNA that control cell activities. They are called the super heros of the cell.
2) Mitochondria are the organelles involved in cellular respiration. They are called the powerhouses of the cell.
3) anaerobic respiration or fermentation does not require oxygen
4) either alcohol or lactic acid
