DefinitionsCell Wall:A rigid layer of polysaccharides lying outside the plasma membrane of the cells of plants, fungi, and bacteria.Nuclear Membrane:The double membrane surrounding the nucleus within a cell.

Attributes of the Nuclear Membrane• The double -layered membrane surrounding the

nucleus of a eukaryotic cell, separating the nucleoplasm from the cytoplasm.

• All cells are covered by a cell membrane the job of a cell membrane is to keep the cytoplasm inside and allow nutrients in and waste products out.

• The nuclear membrane has to membranes each with a typical unit membrane structure. The space between the outer and inner membranes is also continuous with rough endoplasmic reticulum (ER)

Interesting Facts about the Nuclear Membrane

50% of all protein items found in a cell are in the membrane.

Cholesterol holds the membrane together. The nuclear membrane is made of two layers Membranes can fuse with other membranes The nuclear membrane is also known as a nuclear

envelopes, the perinuclear envelope, nuclelemma and the karotheka.

Nuclear Membrane

Attributes of a Cell Wall Cell walls are made of cellulose they are a feature of a plant

cell. The cell wall is ridged and strong. The fibers of a cell wall are laid down in different directions

to add strength to the cell. Cell walls contain other substances making a tough matrix.

There is a “glue” between the cell walls of adjacent cells. Cell walls work with the vacuole to make a cell turgid and to

help support the plant. The cell wall contains three layers the middle manella, the

primary, and the secondary wall The cell wall is only found in a plant cell

Interesting facts about the Cell Wall When too much water enters or leaves the plant cell

the cell wall can prevent the membrane from tearing. the strength of billions of cell walls in a plant enable a

tree to stand tall and its limbs to defy gravity. Did You Know? When you are looking to dry hay or

sticks you are seeing the cell walls of a dead plant cell It prevents cells from bursting as it absorbs water Allows plants to get tall, holds out thin leaves to obtain

light. Cell walls are important for products such as paper,

wood fiber, shelter, and even roughage in our diet.

Go insane in the membrane Thanks For WATCHING!
