Biology Unit 2 + Unit 4

Main structure of the cell membrane

• Phospholipids

• Proteins

• Carbohydrates

The mosaic of components:

• Allow the membrane to be fluid

• Allow the membrane to be rigid

• Allow certain molecules to enter and exit

The head of a phospholipid is composed of

• Glycerol

• Phosphate

• Amino Acids

• Fatty Acids

The tails of a phospholipid is composed of

• Glycerol

• Phosphate

• Amino Acids

• Fatty Acids

The tails of a phospholipid is

• Hydrophilic

• Hydrophobic

• Hydrosis

The 4 phases of the cell cycle are in the order of

• G1, Synthesis, G2, Mitosis

• Synthesis, G1, Mitosis, G2

• G1, Mitosis, G2, Synthesis

• G1, G2, Synthesis, Mitosis

During Prophase, the chromosomes

• The chromosomes become visible

• The chromosomes line up at the center

• The chromosomes gather at opposite ends of cell

During Cytokinesis,

• The chromosomes line up at the center

• The cytoplasm pinches in half

• The chromosomes gather at opposite ends

During Telephase,

• The chromosomes gather at opposite ends

• The chromosomes line up at the center

• The chromosomes become visible

The order of Mitosis is

• Anaphase, Prophase, Metaphase, Telephase

• Prophase, Metaphase, Anaphase, Telephase

• Telephase, Anaphase, Metaphase, Prophase

• Metaphase, Prophase, Anaphase, Telephase
