Chapter 3.0 Flashcards
List the process in which sunlight penetrates a plant leaf
Sunlight Chloroplast Stomata Stomata Thylakoid Chlorophyll, Stored as chemical potential energy in the form of glucose Photo pigment
Where are chloroplasts found
In leaves
Glucose is burned in the ________ to produce ______ energy
Mitochondria
ATP energy
Openings on the underside of a leaf
Will stay closed during the day, To prevent the plant from getting dehydrated’s/ transperating
Open at night to let in carbon dioxide
Stomata
List the process in which light strikes a leaf and stimulates the plant
Light strikes a leaf
This stimulates the guard cells
Causing potassium to come into the cell
Lowering the water concentration causing swelling
Pores in tree stems , Which allow for gas exchange
Lenticel’s
Transfer water
Are hollow
Cohesion/adhesion allows the pull up of water into the stem
Xylem cells
Transfer of sugars
In a plant
Uses Sieve of cells, Which are controlled by communication cells
Phloem
Adhesion
The attraction of water to a surface
Cohesion
The attraction of water to each other
Cells in route pump ions into the cell
The water loss in transpiration creates tension pulling water into the stem
Water is moved through this island and replenished by osmosis
Root pressure
Phloem
From photosynthesis
Glucose transported into the sieve cells
The transport of glucose
Phototropism
Growing toward the sun
Hydrotropism
Growing toward water
Gravitropism
Roots growing downward, stems growing up
