CELLS AND ITS ORGANELLES
CELL: THE FUNDAMENTAL UNITS OF LIFE
1. All organisms are made up of cells
2. The cell is the simplest collection of matter that can be alive
3. Cell structure is correlated to cellular function
4. All cells are related by their descent from earlier cells
CELL STRUCTURE
the cell structure comprises individual components with specific functions
essential to carry out life’s processes.
these components include - cell membrane, cytoplasm, nucleus, and cell
organelles
TOPIC 2: Cells and its Organelles 1
, What is an ORGANELLE?
organelles are the different
structures inside a cell that each
have different jobs or functions to
complete within the cell.
CELLS STRUCTURE
cells are similar to factories with different laborers and departments that
work towards a common objective. Various type of cell perform different
functions
TOPIC 2: Cells and its Organelles 2
, TYPES OF CELL
EUKARYOTIC PROKARYOTIC
are characterized by having: are characterized by having:
a nucleus no nucleus
DNA in a nucleus that is bounded by a coiled DNA in an unbound region
a membranous nuclear envelope called the nucleoid
with membrane-bound organelles no membrane-bound organelles
cytoplasm in the region between the cytoplasm bound by plasma
plasma membrane and the nucleus membrane
are generally much larger than the surface of prokaryotic cells may:
prokaryotic cells
be surrounded by a chemically
complex cell wall
have a capsule surrounding the cell
wall
have short projections that help
attract to other cells or the substrate
