Hace 4 días · Observe the images of the root cap tip. Locate a good example of a cell in each of the following stages: interphase, prophase, metaphase, anaphase, and telophase. Draw the dividing cell in the appropriate area for each stage of the cell cycle, exactly as it appears.
Hace 2 días · Examine the stages of mitosis using a microscope to view cells in an onion root tip. Materials. Onion; Knife; Microscope slides; Stains (e.g., acetocarmine) Microscope; Notebook for observations; Instructions. Cut a small piece from the tip of an onion root. Place the root tip on a microscope slide. Apply a few drops of stain to the root tip ...
Hace 2 días · The interphase accounts for most of the cell’s time and will be the predominant phase of mitosis in the onion root. The results showed that the number of cells going into the mitotic phase decreases as one moves up the onion root. Root tip 1 had a mitotic index (62.76%) and root tip 2 (50%). Introduction Figure 1: Different regions on the ...
Hace 5 días · Transcription factors in coordination with phytohormones form an intricate regulatory network modulating vital cellular mechanisms like development, growth and senescence in plants. In this study, we have functionally characterized the transcription factor OsNAC121 by developing gene silencing and overexpressing transgenic rice plants, followed by detailed analyses of the plant architecture ...

Hace 5 días · Abstract. Organoids and organs-on-chips are two rapidly emerging 3D cell culture techniques that aim to bridge the gap between in vitro 2D cultures and animal models to enable clinically relevant ...
Hace 5 días · Bunching onions, scientifically known as Allium fistulosum, are a remarkable variety of onion that do not form a bulb as their more common counterparts do.These onions are characterized by their long, slender white bases and vibrant green, hollow stalks. Unlike the bulbous varieties, the entire length of bunching onions, from the fibrous roots to the tips of their leaves, is edible, offering a ...
