LIVING BEINGS

Nota:

• Responsible for providing the organism with energy and they form part of some cell structures.
• GLUCOSE, CELLULOSE

Nota:

• Responsivle for provding the organism with energy and they form part of some cell structures. The act as an emergency energy reserve.
• CHROLESTEROL

Nota:

• They contribute to the growth of the organism, they repair tissues.
• COLLAGEN AND MYOS IN

Nota:

• They constitute the genetic material of the cells that intervene in the formation of proteins

Nota:

• Living beings consist mainly of water. Cells carry out all their functions in water.

Nota:

• Mission: To form part of the organism's structure and to regulate some functions.

Nota:

• Oxygen and carbon dioxide participate in the nutrition of iving beings.

1. They are the fundamental unit of live of a living being.
2. It constitutes the base of their structure
3. Living beings only one cell: Unicellular and more than one: Pluricellular
4. Their structure contains:
   1. CYTOPLASM

      Nota:

      • It is a liquid in wich various organuls and molecules float.
   2. CELL MEMBRANE

      Nota:

      • It is the outermost layer that surrounds and protects the cell.
   3. NUCLEUS

      Nota:

      • It is found in the cytoplasm and contains the information necessary to enable the cell to reproduce and carry out this functionns.
      1. THERE ARE TWO PRINCIPAL TYPES OF CELLS:
         1. PROKARYOTIIC CELLS

            Nota:

            • Are the most simple and primitive that exist. They dont have nucleus. The have nucleoid, aribonsomes, cell wall and capsule.
         2. EUKARYOTIC CELLS
            1. Animal cell
            2. Plant cell
