Slide 9 - Drag question

The plant absorbs sunlight through the palisade cells.
The plant absorbs water and nutrients through the roothair cells.
The plant transports water and nutrients up through the xylem vessels.
The plant transports sugars and nutrients down through the phloem vessels.
The plant absorbs carbon dioxide through the stomata cells.
The plant releases oxygen through the stomata cells.

Slide 10 - Drag question

Today:
- limiting factors
- enzymes
- geotropism
- phototropism



Slide 11 - Slide

LIMITING FACTORS:
  • CARBON DIOXIDE
  • WATER
  • SUNLIGHT
  • CORRECT TEMPRATURE FOR ENZYMES

Slide 12 - Slide

WHAT ARE ENZYMES?
  • ENZYMES ARE A CATALYST
  • THEY ARE LITTLE CHEMICAL FACTORIES THAT ARE USED TO SPEED UP CHEMICAL REACTIONS
  • OPTIMUM TEMPRATURE IS BETWEEN 25-40 DEGREES CELCIUS

Slide 13 - Slide

Slide 14 - Slide

Slide 15 - Slide

Slide 16 - Slide

CONTROLLING LIMITING FACTORS:

  • IN FIELDS THESE ARE DIFFICULT TO CONTROL
  • THIS IS WHY WE USE GREENHOUSES
  • MORE CONTROL OVER ALL THE LIMITING FACTORS;
  • ESPECIALLY TEMPRATURE AND WATER SUPPLY

Slide 17 - Slide

geotropism:
  • this is how gravity affects the growth of plants

  • roots are positively geotropic
  • plants are negatively geotropic

Slide 18 - Slide

phototropism:
  • this is how sunlight affects the growth of plants

  • leaves are positively phototropic
  • roots are negatively phototropic

Slide 19 - Slide

Auxin:
  • this is a plant hormone that stimulates growth in certain places of the plant.
