Lymphocytes
The only true cell among the formed elements of blood is the white blood cell (leukocyte). Red blood cells (erythrocytes) and platelets (thrombocytes) are not considered true cells because they lack a nucleus and other organelles.
The third tenet is that (currently at least) living cells only come from other living cells. The three general tenets are: 1) All organisms are composed of one or more cells. 2) The cell is the structural unit of life. 3) Cells can arise only by division from a preexisting cell.

No, insect cell has not a cell wall, insect cell has cell membrane. Only plant cell has cell has cell wall.

The White Blood Cells form in the lymphoid organ because the lymph system is not a closed system and contains a fluid called the lymph.

In 1859, the German pathologist R. Virchow made a significant change in the cell theory concerning the formation of new cells. Contrary to the views of Schleiden and Schwann, R. Virchow argued that cells arise only by reproduction (division)
bacteria do not arise spontaneously by boiling the broth & showing that bacteria appear only when living bacteria were already present.
Only women get that

DNA, the genetic material within the nucleus of the cell, is touched upon, but no specific parts of the cell, or"organelles", are explicitly mentioned in the Cell Theory, which states the following: 1. Cells are the fundamental unit of life. 2. All functions of life occur either within the cell itself or in the interface between cells. 3. Cells can only arise from pre-existing cells. 4. Genetic material is passed from mother cell to daughter cell in the form of DNA.

This principle is known as the rule of foreseeability or the principle of direct damages. It states that damages for breach of contract should only be awarded if they are the direct and foreseeable result of the breach. Indirect or consequential damages that are not a natural consequence of the breach are generally not recoverable.
