Flowering Responses
Thigmotropism
The positive or negative response of a plant to touch
what is ethylene
A gas that is produced by fruits, seeds, flowers, and leaves.
what are the products of phtosynthesis
glucose
oxeygen
what makes mesophyll cells contain that helps make photosynthesis occur
Cholorplasts
Why is photosynthesis important for humans?
Produces the majority of oxygen in the atmosphere
What is Gravitropism
the response of a plant to gravity
what are Plant Hormones
Substances that act as chemical messengers within plants
What are the three things plants need to survive?
Food/sunlight
Water
Oxygen
what are the products of photosyntehsis
Glucose
oxeygen
what are three gasses involved in photosynthesis
water vapor
oxygen
carbon dioxide
Are roots and example of negative thigmotropism
yes becuase they grow away from objects to give them easiest path to soil
Four Types of plalnt hormones
Auxins
Ethylene
Gibberellins
Cytokinins
What are the processes plants use to obtain food and energy
photosynthesis
cellular respiration
What organlee does photosynthesis take place in
choroplasts
what orginell does photosythesis take place in
Chloroplasts
What are the products of Cellular Respiration?
Carbon Dioxide
Water
ATP
what is Cytokinins
Increases the rate of cell division and slows the aging process of flowers and fruits
what's the difference between reactants and products
reactans is what goes in the equation and the product is the end result of the equation
what are the reactants of photosyhtneis
sunlight
carbon dioxide
water
what are the three types of flowering responses
long day
short day
day nuteral
Short-Day Plants
Plants that need 12 or more hours of darkness in order to begin flowering
What is Gibberellins
Present in rapidly growing areas of plants, such as roots and stems
Two examples of vascular tissues
Xylem
Pholem
How does Phloem facilitate photosynthesis / cellular respiration?
By distributing food throughout the plant
How does Xylem facilitate photosynthesis / cellular respiration?
By distributing water throughout the plant
