Definitions
What are Flowering Plants?
Plants that produce flowers in order to reproduce.
Where are Cytokinins produced?
They are produced in the roots of plants and carried throughout plant by Xylem
Is Phototrpoism a negative or positive tropism?
Positive
Xylem transports ___ from the roots of plants to cells within plants?
Water
What is Thigmotropism?
The positive or negative response of a plant to touch.
what is Photoperiodism?
A plant's response to the number of hours of darkness in its environment
What do Gibberellins increase?
They increase the rate of cell division and cell elongation, causing the plant to grow quickly
what are Photoreceptors?
Chemicals in plants that allow it to detect light
What is Photosynthesis?
A series of chemical reactions that converts light energy, carbon dioxide, and water into glucose and oxygen.
When vines wrap around objects is it negative or positive?
Positive.
What is Gravitropism?
The response of a plant to gravity
what are three types of flowering responses?
Long-day
Short-day
Day-neutral
what are the Potential Stimuli?
Light
Touch
Gravity
what does Phloem do?
*What is plant food called?
Moves food from food-making cells to all plant cells
Glucose
What plants are known to wrap around or cling to structures?
Vines
What do Auxins do?
Increase plant growth and play a part in positive phototropism.
What is he difference between Short-Day Plants and Long-Day Plants?
Short-Day Plants need 12 or more hours of darkness in order to begin flowering, whilst Long-Day Plants need less than 10-12 hours of darkness.
What is the difference between a positive and negative Tropism?
Growth towards the stimulus is positive and Growth away from the stimulus is negative.
What are the reactants of photosynthesis?
Light energy (sunlight)
Carbon Dioxide
Water
what are Tendrils?
Structures on plants that allow them to wrap around or cling on to objects
What are Plant Hormones?
Substances that act as chemical messengers within plants
What does Ethylene do?
* what can happen if it gets too much exposure to Ethylene?
Responsible for the ripening of fruit
Too much exposure to ethylene can lead to rotting
Which part of the plant typically goes through negative phototropism?
Roots because it grows away from the light.
what are Reactants?
What are Products
Materials that change to form a new substance
What is created when reactants are transformed
what are the Reactants and Products of Cellular Respiration?
Reactants:
Glucose (food)
Oxygen
Products:
Carbon Dioxide
Water
ATP (energy)
