Chapter 9 Flashcards
What is Glucose use for?
It is a Carbohydrate that gives the cell energy
What is created during photosynthesis?
Oxygen and Glucose
What traps the sun’s energy in a leaf?
Chlorophyll
What does the Epidermis do?
It protects the leaf, it is the waxy layer covering the leaf
What do the Palisade Tissue cells do?
They’re packed with Chloroplasts and are a main component in Photosynthesis
What do spongy tissue cells do?
Found below the Palisade layer, Gas and Water exchange between the Cells and the environment
What does the Stomata do?
They are small openings in the Epidermal layer (mostly on the underside of the leaf), allow CO2, O2, and H2O to exchange. Guard cells open and close the Stomata
What are Vascular Tube cells? How does Phloem and the Xylem travel?
Arranged Phloem and Xylem in Vascular Bonding roots. Phloem: Carries sugars DOWN to other parts of the plant
Xylem: Carries water/minerals UP to other parts of the plant
What cell uses cellular respiration? What cell uses Photosynthesis?
Animal and Plant, respectively
What do animal cells create through cellular respiration?
They consume oxygen and give out CO2 and water
What do plant cells create during photosynthesis?
They consume CO2 and give out water and oxygen
What are Lenticels?
Small openings in bark that allows for gas exchange
What are the guard cells controlled by?
The amount of water in the guard cell causes the cell to move back or or closer together
What is Turgor Pressure
When the high water pressure within the gaurd cell causes it to swell and press up against the cell membrane. This causes the stomata to open and lets water, which is the process of transpiration
What happens to the guard cells when there is no water? Why do plants wilt?
The plants need turgor pressure to stay rigid and they need water for that, so if there
