|
Cell wall (define) |
made of carbohydrate cellulose |
|
|
Middle lamella (define) |
- outermost later of the cell - pectin layer |
|
|
Plasmodesmata (define) |
channel (in cell walls) through which single stranded cytoplasm flows |
|
|
Pits (define) |
- cell wall that only has one layer - very thin region of cell wall, arranged in pairs (adjacent cells) |
|
|
Amyloplast (define) |
- small organelle - enclosed by membrane - contains starch granules |
|
|
Vacuole (define) |
a vesicle in the cytoplasm (enclosed by membrane) containing fluid/ cell sap |
|
|
Tonoplast (define) |
vacuholar membrane |
|
|
Cell wall (function) |
Provides structural supports |
|
|
Middle lammella (function) |
- Acts as an adhesive sticking adjacent plant cells together - gives plant stability |
|
|
Plasmodesmata (function) |
- allow transport of substances - allows communication between cells |
|
|
Pits (function) |
- allows transport of substances BETWEEN cells |
|
|
Chloroplast (function) |
site of photosynthesis > creates food (glucose) for plant |
|
|
Amyloplast (function) |
- storage of starch grains - convert starch into glucose > when plant needs energy |
|
|
Vacuhole (function) |
- Keep cells turgid - involved in breakdown & isolation of unwanted chemicals in cells |
|
|
Tonoplast (function) |
Controls what enters & leaves the vacuhole |
|
|
Similarities between an animal & plant cell |
Contain some of the same organelles: cell membrane, nucleus, mitochondria, ER, GA, ribosomes, cytoplasm, vacuhole |
|
|
Difference between an animal & plant cell |
- starch instead of glycogen - contains amyloplast, middle lamella, pit, chloroplast, permanent vacuhole, plasmodesmata, cell wall (animal cell x contain these things) |
|
|
Chloroplast (structure) |
- small flattened organelle - double membrane bound - thylakoids membranes in stroma - grana > stacks of thylakoids membrane - Lamellae > thin, flat piece of thylakoids membrane linking grana |
|
|
Where does photosynthesis occur |
- photosynthesis in chloroplast - light dependent reaction > grana - light independent reaction > stroma (think fluid) |
