Plant Characteristics
Provides support and protection.
What is the cell wall.
Series of chemical reactions that convert light energy, water, and carbon dioxide into the food-energy molecule glucose and give off oxygen.
What is photosynthesis?
Organelle where photosynthesis occurs.
What is the chloroplast?
Growth away from a stimulus is considered _________.
negative.
Any changes in an organism’s environment that cause a response.
What are stimuli?
Store a watery liquid called sap.
What is the Vacuole?
Series of chemical reactions that convert the energy in food molecules into a usable form of energy called ATP.
What is cellular respiration?
Products of photosynthesis.
What are Oxygen and Glucose?
The growth of a plant toward or away from light.
What is phototropism?
Special structures that respond to touch
Near the top surface of the leaf which are packed together.
What are palisade mesophyll cells?
Waxy, protective layer on their leaves, stems, and flowers
What is the cuticle?
What are the reactants of photosynthesis.
What are carbon dioxide, sun, and water.
Response of a plant to touch.
What is thigmotropism?
Hormones responsible for phototropism
What are auxins?
Have open spaces between them, and gases needed for photosynthesis flow through the spaces.
What are spongy mesophyll cells?
Organic compound made of chains of glucose molecules found in the cell wall.
What is cellulose?
Describe the first step of photosynthesis.
Light is captured for energy.
Plants that flower when exposed to less than 10-12 hours of darkness
What are long day plants.
Which 2 hormones increase the rate of cell division?
What are gibberellins and cytokinins?
What are 3 adaptation plants had to make to live on land.
Cellulose, vascular tissue, seed dispersal, cuticle. stomata(water & gas exchange)
Composed of tubelike cells that transport water and nutrients in some plants.
What is vascular tissue?
Describe the second step of photosynthesis.
Sugars are made.
Describe all the ways in which the plant responds to gravity.
Against above ground and roots grow with gravity.
What are 2 hormones/ chemicals that could be used to better transport produce long distances.
What are cytokines and ethylene gas?
