Photosynthesis
What is the photosynthesis equation (in words)
water + carbon dioxide + light energy = sugar + oxygen
Define transpiration
Process of water being pulled up the xylem
Which one is primary growth and which one is secondary growth?
Growth where the stems grow thicker
Growth at the tips of plants
Growth at the tips of plants - Primary
Growth where the stems grow thicker - Secondary
What is any movement in a plant, when in response to a stimulus?
tropism
How many Carbons are in glucose?
What structure of the leaf allows gases to pass in and out?
Stomata
What are the two types of vascular tissue?
Phloem and Xylem
What is the growth region of the plant? This is where primary and secondary growth originate in plants
Meristem
Define Geotropism and Thigmotropism
Geo-The response of a plant to the effects of gravity.
Thigmo- plant's movement or growth response to touch
If the circumference of a tree is 31m then what is the diameter of the tree?
C=pi x d
31m = 3.14d
d=9.87m
What is the molecular structure of glucose
C6H12O6
What do the xylem and phloem do?
Xylem carries water and minerals
Phloem carries food
What are the two meristems responsible for primary growth?
Apical meristem
Intercalary meristem
Explain Phototropism vs Heliotropism
Phototropism is a directional response of plants to light while Heliotropism is a very rapid response to sunlight where the plant follows the sun throughout the day
What does the abbreviation ATP mean?
Adenosine triphosphate
What is the molecular equation for photosynthesis
6CO2 + 6H2O → C6H12O6 + 6O2
What is located between the xylem and phloem and produces an increase in the plant's vascular tissue?
Vascular cambium
What plant hormone regulates the length of most plant cells by contributing to the growth and elongation of the plant
Auxin
What are 4 seed dispersal methods
Wind
Water
Animals
Bursting
Where are both meristems found?
Apical - at the tips of stems and roots
Intercalary - between mature tissue in stems near the base of stems and leaf blades
What molecular compound stores energy from photosynthesis?
ATP
What are the three components of the bark? The outer layer in woody stems
Cork
Cork cambium
Phloem
What is located outside the phloem and produces cork tissue?
Cork cambium
Explain Heliotropism with Sunflowers
Sunflowers follow the sun at the start of the day until sunset and then return to the east in preparation for the next day.
Explain roots in terms of Geotropism, and Phototropism. Using "negative" and "positive"
Negative Phototropism
Positive Geotropism
