Answer 1

$\huge\mathfrak\pink{Answer}$

I think you study in LPS

1. In biology, the smallest unit that can live on its own and that makes up all living organisms and the tissues of the body. A cell has three main parts: the cell membrane, the nucleus, and the cytoplasm. ... Parts of a cell. A cell is surrounded by a membrane, which has receptors on the surface
2. The nuclear envelope, also known as the nuclear membrane, is made up of two lipid bilayer membranes that in eukaryotic cells surrounds the nucleus, which encases the genetic material. The nuclear envelope consists of two lipid bilayer membranes: an inner nuclear membrane and an outer nuclear membrane.
3. a rigid layer of polysaccharides lying outside the plasma membrane of the cells of plants, fungi, and bacteria. In the algae and higher plants it consists mainly of cellulose.
4. A vacuole is a membrane-bound organelle which is present in plant and fungal cells and some protist, animal, and bacterial cells.

Answer 2

1- “A cell is defined as the smallest, basic unit of life that is responsible for all of life's processes.”

2- A nuclear membrane is a double membrane that encloses the cell nucleus. ... The nuclear membrane includes an array of small holes or pores that permit the passage of certain materials, such as nucleic acids and proteins, between the nucleus and cytoplasm.

3- A cell wall is a structural layer surrounding some types of cells, just outside the cell membrane.

4- Vacuoles are membrane bound transparent organelle present in both animal and plant cell. They are small and many in animal cells whereas large and one in most of the plant cells..
