Thick outer covering of a plant cell?
the cell wall is a rigid outer layer unique to plant cells. it shapes and protects the cell, unlike animal cells, whose outer most layer is the plasma membrane (a layer that lies beneath the cell wall in plant cells)
Tough outer covering of a bone?
The tough outer covering of a bone is called the periosteum. It is a dense, fibrous membrane that protects the bone and provides a site for muscle attachment. The periosteum also contains blood vessels and nerves that help nourish and communicate with the bone tissues.
What are the key differences between gram-negative and gram-positive bacteria?
Gram-negative bacteria have a thin peptidoglycan layer in their cell wall and an outer membrane, while gram-positive bacteria have a thick peptidoglycan layer but lack an outer membrane. Gram-negative bacteria also have lipopolysaccharides in their outer membrane, which gram-positive bacteria do not have. Additionally, gram-negative bacteria are typically more resistant to antibiotics due to the presence of the outer membrane.
How many molecules thick is a cell membrane?
If I remember my biology correctly, it is two molecules thick. The molecules are polar-nonpolar phospholipids. There are 3 parts to each of these molecules: a hydrophilic (water-loving) head, and two hydrophobic (water-fearing) tails. The outer layer molecules orient themselves so that the head faces outwards - towards the water that our cells are suspended in. Both of the tails face inwards towards the inner layer. The inner layer molecules face the opposite direction, with the hydrophilic heads facing towards the inside of the cell and the hydrophobic tails facing towards the outer layer. Thus the tails of the outer and inner layers are attracted to each other, and keeps the water inside of the cell in, and the water outside of the cell out.
What is a waxy covering on the skin of a leaf?

What is the thick outer covering located outside of the cell membrane?
Protoplasm
What is the outer covering of a leaf?

What is a seals outer covering?

Is hair the outer covering of a seal?
No, hair is not the outer covering of a seal. Seals have a thick layer of blubber under their skin, and their outer covering is made up of a combination of thick, waterproof fur or hair. This fur helps seals regulate their body temperature and stay warm in cold water.
What is the thick outer membrane of the acolyte?
The thick outer membrane of the acolyte is called the plasma membrane. This membrane acts as a protective barrier and regulates the movement of substances in and out of the cell. It is composed of a phospholipid bilayer embedded with proteins that help facilitate various cellular processes.
What is the reason that plant cells have an extra thick outer covering andwhatis the outer covering called?
Plant cells have an extra thick outer covering called a cell wall, which provides structural support to the cell and protects it from mechanical damage. The cell wall is made up of cellulose fibers, which give it strength and rigidity.
What does a cell membrane do in all cells?
cell membrane is the thick outer layer that dicides what enters and exites the cell.
Thick outer covering of a plant cell?
the cell wall is a rigid outer layer unique to plant cells. it shapes and protects the cell, unlike animal cells, whose outer most layer is the plasma membrane (a layer that lies beneath the cell wall in plant cells)
What is the thick outer part of a plant cell that surounds the cell membrane?
The cell wall
Size of the plasma membrane in an animal cell?
The average is 7 nanometres in width (from outside to inside the cell).
Why cant the paramecium changes shape like the ameba?
because it has a thick outer membrane called the pellicle
