the fate of the products of photosynthesis Flashcards
What is the main photosynthetic organ in a flowering plant?
The leaf is the main photosynthetic organ in a flowering plant.
In what part of a leaf does photosynthesis take place?
in the chlorophyll-containing cells of the leaf
Where is most chlorophyll in chloroplasts located in the structure of a leaf?
chlorophyll is contained in chloroplasts, and these are mostly located in the ground tissue or mesophyll of the leaf.
What are the products of photosynthesis
The products of photosynthesis are oxygen and glucose.
What is the trip oxygen must take in order to get into the atmosphere?
Oxygen produced in photosynthesis can diffuse into the air spaces of the leaf. Oxygen can then diffuse out through the stomata into the atmosphere.
What can the oxygen produced in photosynthesis be used for internally?
some of the oxygen formed in photosynthesis can be used in leaf cells for respiration.
What is the main carb produced in photosynthesis? What is this immediately used for?
- Glucose is the main carbohydrate produced in photosynthesis. Glucose may be used immediately for respiration (continued overleaf)
what is glucose converted to for storage?
Glucose may be converted to starch for storage.
Where is some of the starch stored in leaf cells?
Some of this starch is stored in leaf cells, especially the spongy mesophyll cells.
What can some of the glucose be converted to (another carb)?
Some of the glucose may be converted to another carbohydrate called sucrose (which is table sugar).
How is sucrose transported around the plant?
Sucrose enters phloem sieve tube cells in the leaf and is then transported throughout the plant. The solution of sugary water carried in phloem is called phloem sap.
What is phloem sap?
the solution of sugary water carried in phloem
What is the main function of phloem?
Phloem carries food to all parts of the plant.
List some growth areas of plants
Growth areas can include buds, leaves, stems, roots or flowers.
What can food produced by plants be used for in the plants?
The food can then be used for respiration, to form new structures in the plant or it can be stored as starch.
