Photosynthesis
The process in plants where glucose is produced from sunlight in the leaves, converting light energy into chemical energy within the chloroplasts.
Factors affecting photosynthesis
Temperature, light intensity, and carbon dioxide concentration influence the rate of photosynthesis.
Practical investigating photosynthesis
Experiments using water plants like Elodea to observe oxygen bubbles released during photosynthesis and investigating factors like light intensity and carbon dioxide concentration.
Starch production experiment
A method to test for starch in leaves by using iodine solution, where the presence of blue-black color indicates starch production due to photosynthesis.
Leaf structures
Components like waxy cuticle, upper epidermis, palisade mesophyll, spongy mesophyll, lower epidermis, guard cells, and stomata play roles in photosynthesis and gas exchange in plants.
Mineral ions
Magnesium is essential for chlorophyll production, while nitrate is needed for amino acid synthesis in plants. Deficiencies can lead to yellowing of leaves and stunted growth.
