Plant Health And Disease Flashcards
What are the main organs in a plant
Leaf
Root stem
What pathogens can infect plants
Viral
Bacterial
Fungal
Protist
Equation for photosynthesis
Carbon dioxide + water
——>
Glucose + Oxygen
What affects the rate of photosynthesis
Temperature
Carbon dioxide concentration
What is inverse proportion
Where if 1 variable increases the the other variable decreases
Define mass transport
Bulk movement of materials from exchange surfaces to the cell
Examples of substances the get mass transported
Sugar and water
What are the two vessels in a plant
Phloem
Xylem
Features of a phloem
Movement of sugars
From leaf to root
Process is called translocation
Features of a xylem
Movement of water and minerals
From root to leaf
Process is transpiration stream
Define transpiration
The loss of water from the stomata
Equation of transpiration
Rate=
