Question

draw the first stage in mitosis, prophase.

Explanation:

To draw prophase (first stage of mitosis):

1. Nuclear Envelope: Start by lightly sketching the nuclear membrane (a circle or oval) beginning to break down (show some irregularities or partial dissolution).
2. Chromosomes: Draw condensed, visible chromosomes (thick, X - shaped structures as they have replicated and are composed of two sister chromatids). Place several of these within the area where the nucleus was.
3. Centrioles (in animal cells): If representing an animal cell, draw two pairs of centrioles moving towards opposite poles of the cell (small cylindrical structures).
4. Spindle Fibers: Sketch the beginning of spindle fiber formation, with fibers extending from the centrioles towards the chromosomes.

For a plant cell, omit centrioles and adjust the cell shape (more rectangular) with a cell wall, and still show the nuclear envelope breakdown, condensed chromosomes, and spindle fiber formation from the cell poles.

Answer:

(Here is a textual description of the drawing steps as above. To create the actual drawing, follow the steps: draw a cell outline, then the breaking nuclear envelope, condensed chromosomes, centrioles (if animal) or spindle from poles (if plant), and spindle fibers.)
