Answer 1

$\huge{ \underline{ \bold{Answer:}}}$

✏ What is cell membrane made up of ?

→ All living cells are made up of tiny organelles. Cell membrane is composed mainly of phospholipids and proteins.

✏ How many parts does nucleus have?

→ The nucleus has 4 different parts.

$\bold\star{Nucleur \: Membrane}\star$

⋆NucleurMembrane : Nucleus has double layered covering called membrane. It has numerous minute pores. These pores allow the transfer of materials from inside the nucleus of the cytoplasm.

$\bold\star{Nucleolus}\star$

⋆Nucleolus : It is sperical in shape. It is first recognised by Fontana. It plays a vital role in making proteins in the cell.

$\bold\star{Chromatin}\star$

⋆Chromatin : This helps in division of cells.

Answer 2

$\huge\boxed{Hola!!!}$

● What is cell membranes made up of?

✔It is made up of phospholipids

( phosphate + water )

It is also consists of proteins and glycoproteins.

● What are the parts of Nucleus?

✔✔It consists five parts

The parts and its function are listed below-

✌Nuclear membrane ✌

It plays an important role in trransport of material from cytoplasm to the nucleus.

✌Nuclear pores ✌

The materials exchanged between nucleus and cytoplasm must traverse the nuclear pore complexes.

✌Nucleoplasm ✌

It is nucleus sap that contains DNA , RNA,proteins, enymes etc.

✌Nucleolus ✌

It helps in mitosis, exchange of genetic material and protein synthesis.

✌Endosomes✌

They are like nucleolus but smaller in size, showing changeable structure.
