•Prokaryotes = cells that do not have membrane bound organelles (e.g. most unicellular organisms, such as bacteria) and divide by binary fission
•Eukaryotes = cells that contain membrane bound organelles
•Eukaryotes = cells that contain membrane bound organelles
Organelle Functions:
cell membrane - allows substances to pass into the cell and keeps unwanted substances out.
cytoplasm - the jellylike material outside the cell nucleus in which the organelles are located.
Golgi Apparatus - packages and distributes proteins into different categories .
lysosome - Digestion of cell nutrients.
mitochondrion - converts the energy stored in food into ATP (chemical energy) for the cell.
nuclear membrane - the membrane that surrounds the nucleus.
nucleolus - an organelle within the nucleus - where ribosomal RNA is produced.
nucleus - controls many of the functions of the cell and contains DNA (in chromosomes).
ribosome - creates proteins.
endoplasmic reticulum - transports materials through the cell (and sends proteins to the Golgi Apparatus).
vacuole -storage for waste material.
chloroplast (plant only) - where photosynthesis takes place (takes chemical energy from sunlight)
cell wall (plant and prokaryotic only) - gives the cell support and structure. The cell wall also bonds with other cell walls to form the structure of the plant.
pili (Prokaryotic only) -attaches cell's surface to other cells.
flagella (prokaryotic only) - allows locomotion

TOK: The world that we inhabit is limited by the world that we see. Is there any distinction to be drawn between knowledge claims dependent upon observations made by sense perception and knowledge claims dependent upon observations assisted by technology?
Yes, because technology can replace our senses and make our perception have a more clear view of what we are seeing. In this, case, the microscope is replacing our naked eyes, which made it possible for us to understand cells and their inner structures.
