To our knowledge, a method for chloroplast counting using maceration has not yet been applied to leaves with thick, lignified cell walls, such as coniferous needles. These cells have a lot of chloroplasts in them, which is why theyre the main sites of photosynthesis in the leaf (since chloroplasts conduct photosynthesis). Because no sunlight reaches these areas, chloroplasts would be useless. Chemical reactions take place here, Organelle which contains chlorophyll band allowing for photosynthesis, Contains DNA and controls the activities of the cell, Gel like ground substance with enzymes. It can be influenced by internal factor Based on the above-presented lines of evidence, we conclude that the presented optical disector method for chloroplast counting, using stacks of confocal microscopic images acquired from thick tissue sections accompanied by SUR sampling, is a very efficient method for estimating chloroplast number per mesophyll cell. Hayashida Gundersen for the plant Beneath the palisade mesophyll are the spongy mesophyll cells, which also perform photosynthesis. Gases dissolve as they move through and out of this water. Why not for side collisions and rollovers? Chloroplasts are also found in photosynthetic tissues that do not appear green, such as the brown blades of giant kelp or the red leaves of certain plants. Methods based on these principles were then improved (Possingham and Smith, 1972), and modified protocols have been widely used, e.g. This complex is usually located close to the cell nucleus. .
