Question

select the true statements. phospholipid tails touch the cytoplasm inside the cell. phospholipid heads touch the intracellular environment. phospholipid heads touch the extracellular environment. the cell membrane is made of two layers of phospholipids.

Explanation:

• Phospholipid tails are hydrophobic and face inward, not touching the cytoplasm directly.
• Phospholipid heads are hydrophilic. They touch both the intracellular (inside the cell) and extracellular (outside the cell) environments which are aqueous.
• The cell membrane is a phospholipid bilayer, meaning it has two layers of phospholipids.

Answer:

Phospholipid heads touch the intracellular environment.
Phospholipid heads touch the extracellular environment.
The cell membrane is made of two layers of phospholipids.
