What is the cell membrane made of?
|
phospholipids, cholesterol, proteins and carbohydrates.
|
|
The phospholipid membrane allows (blank) to easily pass in and out of the cell through diffusion.
|
lipid-soluable material
|
|
The presence of (blank) decreases the fluidity as a type of sealer for the membrane, thus making it more stable.
|
Cholesterol
|
|
The Cell Wall or membrane is made up of a (blank).
|
phospholipid bilayer
|
|
The phospholipid bilayer has two basic parts: name them
|
The hydropholic (water-loving) head and the hydrophobic (water-hating) tail.
|
|
(Blanks) have several functions. Some form pores or openings to permeit passage of materials; other are enzymes that also help substances enter the cell.
|
Proteins

|
The name for energy production within the cells is (blank).
|
Cellular Respiration
|
|
One cell with 46 chromosomes splitting into two identical cells with 46 chromosomes eacy is called.
|
Mitosis
|
|
Cells, such as sperm and egg cells, divide into two haploid cells.
|
miosis
|
