What are the reactants and products of photosynthesis?
Reactants: Carbon dioxide (CO₂) and water (H₂O)
Products: Glucose (C₆H₁₂O₆) and oxygen (O₂)
What is the function of phloem in vascular plants?
Phloem transports organic nutrients, particularly sugars produced during photosynthesis, from the leaves to other parts of the plant.
What is the role of roots for plants?
Roots anchor the plant, absorb water and nutrients from the soil, and store food.
What cell organelle is ATP produced in?
mitochondria.
How do the roots, stems, and leaves interact?
Roots absorb water and nutrients, stems transport these to the leaves, and leaves perform photosynthesis to produce food, which is then transported to other parts of the plant.
What is the function of xylem in vascular plants?
Xylem transports water and dissolved minerals from the roots to the rest of the plant and provides structural support.
What is the role of ATP in biological processes?
ATP (adenosine triphosphate) acts as the primary energy carrier in cells, providing energy for various cellular processes such as muscle contraction, active transport, and biosynthesis of macromolecules.
What is the difference between aerobic and anaerobic respiration?
Aerobic respiration requires oxygen and produces more ATP, while anaerobic respiration does not require oxygen and produces less ATP.
What parts of the flower are the male reproductive organs? What are their functions?
The male reproductive organs are the stamens, which consist of anthers (produce pollen) and filaments (support the anthers).
Where does cellular respiration occur in a cell?
mitochondria of eukaryotic cells.
What is the process that breaks down glucose?
Glycolysis is the process that breaks down glucose into pyruvate, yielding ATP and NADH.
What parts of the flower are female? What are their functions?
The female reproductive organs are the pistils, which consist of the stigma (receives pollen), style (connects stigma to ovary), and ovary (contains ovules).
Where is energy stored in ATP?
high-energy phosphate bonds, particularly the bond between the second and third phosphate groups.
What is the purpose of colorful petals?
attract pollinators such as bees, butterflies, and birds, aiding in the process of pollination.
What stage of cellular respiration is the majority of ATP produced in?
electron transport chain stage of cellular respiration.
What happens to the products of photosynthesis?
Glucose is used for energy and growth, while oxygen is released into the atmospher.
What is the difference between alcoholic fermentation and lactic acid fermentation?
Alcoholic fermentation produces ethanol and carbon dioxide, while lactic acid fermentation produces lactic acid.
What do aerobic respiration and lactic acid fermentation have in common?
Both processes begin with glycolysis, where glucose is broken down into pyruvate.
What part of a leaf allows for gas exchange?
Stomata
What are the reactants and products of cellular respiration?
Reactants: Glucose (CH.O.) and oxygen (O.)
Products: Carbon dioxide (CO,), water (HO), and ATP.
What happens to plants when they close their stomata?
gas exchange is reduced, which can limit photosynthesis and reduce water loss.
