Question

the cell membrane, also referred to as the plasma membrane, is a structure that surrounds all cells. the purpose of the cell membrane is to assist the cell in maintaining homeostasis (stable internal conditions) by controlling what enters and exits the cell. stop and watch watch the following video: https://youtu.be/iadrqvizhzy the cell membrane is made of phospholipids. take a look at the structure of a phospholipid. these phospholipids form what’s referred to as a phospholipid bilayer, where the hydrophilic heads face the water that surrounds the cell and the hydrophobic tails are away from water that surrounds the cell. the phospholipid bilayer of the cell membrane is described as a fluid mosaic. label each image below with the following identifying terms: plant cell, prokaryotic cell, animal cell. what does the term hydrophilic mean? what does the term hydrophobic mean?

Explanation:

1. The round - shaped cell with a nucleus is an animal cell. Animal cells are eukaryotic and usually have a round or irregular shape.
2. The cell with a cell wall and a large central vacuole is a plant cell. Plant cells have these characteristic structures for support and storage.
3. The cell with no nucleus and a simple structure is a prokaryotic cell. Prokaryotes lack a membrane - bound nucleus.
4. Hydrophilic means having an affinity for water. Hydrophilic substances can dissolve in water or interact with water molecules.
5. Hydrophobic means having a repulsion for water. Hydrophobic substances do not dissolve in water easily and tend to avoid water.

Answer:

1. First cell: Animal cell
2. Second cell: Plant cell
3. Third cell: Prokaryotic cell
4. Meaning of hydrophilic: Having an affinity for water
5. Meaning of hydrophobic: Having a repulsion for water
