Biology is the science of life and living organisms. Aside from instruction relevant to this, students are given the chance to learn complex laboratory techniques (e.g., DNA extraction) as well as develop mindful opinions about controversial topics in biology (e.g., stem-cell research and genetic modification).

B1 cells are a sub-class of B cell lymphocytes that are involved in the humoral immune response. They are not part of the adaptive immune system , as they have no memory, but otherwise, B1 cells perform many of the same roles as other B cells: making antibodies against antigens and acting as antigen-presenting cells .
Cell biology (also cellular biology or cytology) is a branch of biology that studies the structure, function, and behavior of cells. [1] [2] All living organisms are made of cells. A cell is the basic unit of life that is responsible for the living and functioning of organisms. [3] Cell biology is the study of the structural and functional ...
These cells may be cells isolated from a donor organism (primary cells) or an immortalised cell line. The cells are bathed in a culture medium, which contains essential nutrients and energy sources necessary for the cells' survival. [8] Thus, in its broader sense, "tissue culture" is often used interchangeably with "cell culture".
He coined the term cell (from Latin cellula, meaning "small room" [41]) in his book Micrographia (1665). [42] [40] 1839: Theodor Schwann [43] and Matthias Jakob Schleiden elucidated the principle that plants and animals are made of cells, concluding that cells are a common unit of structure and development, and thus founding the cell theory.
Undifferentiated cells have not completed differentiation or specialization, thus retaining their cell potency and oftentimes being highly proliferative. [19] This is often the final cell state after the dedifferentiation process is completed and maintained, as cells become less specialized.
In cell biology, an organelle is a specialized subunit, usually within a cell, that has a specific function.The name organelle comes from the idea that these structures are parts of cells, as organs are to the body, hence organelle, the suffix -elle being a diminutive.
