Energy Processing
A series of chemical reactions that convert light energy, water, and carbon dioxide into the food molecule glucose and gives off oxygen
Photosynthesis
Any changes in an organism's environment that cause a response.
Stimuli
Occurs when the life cycle of an organism alternates between diploid and haploid generations
Alternation of generation
A series of chemical reactions that convert the energy in food molecules into usable forms of energy called ATP
Cellular Respiration
A response that results in plant growth toward or away from stimulus
Tropsism
The daughter cells produced from haploid structures
Spores
What is the role of the xylem? What is the role of the phloem?
Xylem - transport water
Phloem - transport liquid sugar
A plant's response tp the number of hours of darkness in its environment
Photoperiodism
Name the 4 hormones that were listed in the book.
Auxins, Ethylene, Gibberellins and Cytokinins
Occurs when pollen grains land on a female reproductive structure of a plant that is the same species as the pollen grain
Pollination
What are the small openings found on the bottom of the leaf called?
Stomata
Substances that act as chemical messengers within plants
Plant hormones
What are the 3 types of Photoperiodism's and how many hours of darkness do they represent.
Long-Day (10-12 hours of darkness)
Short-Day (12 or more hours of darkness)
Day-Neutral (does not depend on amount of darkness)
Embryo
What are the 2 types of mesophyll and what are their roles in the leaf?
Palisade - Packed together to expose cells to light
Spongy - Open spaces between cells to allow for gases to pass through
Name the 3 types of tropisms and what stimulus they are in response to.
Phototropism - light
Thigmotropism - touch
Gravitropism - gravity
Made up of an embryo, its food supply, and a protective covering
Seed
Draw and label a flower.
Make sure to include: pistil, sepal, ovules, petal, stamen, anther, filament, ovary, style, stigma
