6. Cell structure Flashcards
Cell def.
Basic unit of structure and function in an organism
Cell organelles
A cell component that performs a specific function for the cell
List organelles
Mitochondria Chloroplast Vacuole Ribosomes Nucleus Cell membrane and wall
Diagram and label
- Plant
- Animal
Plant: cell wall and chloroplast and vacuole
Function of cell membrane
Semi permeable
Separates the cell from the outside
Cell wall function
Rigid shape and defined shape
Gives support and strengthens the cell
Function and appearance of Cytoplasm
Appearance: clear jelly like fluid
Function: Holds all organelles and keep them in the cell.
What is Protoplasm?
All living parts of the cell
Mitochondria function and where there are a lot and a little in animal and plants.
Respiration, provides energy
Loads: Meristems(plant) Muscle cells(animal)
Little: ground tissue(plant) Fat tissue (animal)
Diagram of mitochondria
Outer and inner membrane
Lumen
Cristae
Ribosomes structure and function
Red circular dots
Function: to make protein
Chloroplast function and structure
Photosynthesis
Lamella
Granium- light stage of photosynthesis(contains chlorophyl)
Stroma- dark stage
Outer membrane
Vacuole what are they and their function
Membrane bound sacs within the cytoplasm.
Contains fluid called cell sap.(salts,sugar and pigments)
Function: storage, support, waste disposal, protection and growth.
Nucleus function and parts. Diagram
Controls activities of cell.
Nucleolus: makes ribosomes Double nuclear membrane: semi permeable Nuclear pore: passageway Chromatin: contains DNA Nucleoplasm: holds parts of nucleus together.
Cell membrane diagram
Phospholipids
Phosphate head
Lipid tail
Proteins
Phospholipids form a bilayer.
