Internal Structure of a Leaf for Photosynthesis
What do you call on the single layer of cells that covers the leaves, flowers, roots and stems of plants?
epidermis
In which part of the leaf the photosynthesis occurs?
chloroplast
What is photosynthesis?
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
What are the products of light reaction of photosynthesis?
NADPH, ATP and oxygen
Which part of the leaf transports photosynthetically prepared food materials from the leaves to the storage organs and later from storage organs to the growing regions of the plant body?
phloem
What are the structures that can be found inside the chloroplast?
thylakoids, grana and stroma
What is the product of photosynthesis which is vital to humans and animals?
oxygen
What is the product of dark reaction?
glucose
What is the difference between phloem and xylem?
Xylem transports and stores water and water-soluble nutrients in vascular plants. Phloem is responsible for transporting sugars, proteins, and other organic molecules in plants.
What colors of white light absorbs by the chlorophyll and will be used in photosynthesis?
red light and blue light
What are the raw materials for photosynthesis?
sunlight, chlorophyll, water and carbon dioxide
What is the difference between light and dark reaction of photosynthesis?
The light reaction is the initial stage of photosynthesis which traps light energy to produce ATP and NADPH, whereas dark reaction is the second step of photosynthesis which utilizes the energy from ATP and NADPH to produce glucose.
