Onion (Allium) root tip mitosis Credit:WIM VAN EGMOND/VISUALS UNLIMITED, INC. /SCIENCE PHOTO LIBRARY
Light micrograph showing a section through a leaf. Each cell contains several round, green vescicles which are known as chloroplasts Credit: JOHN DURHAM/SCIENCE PHOTO LIBRARY
Plant phloem tissue. Light micrograph of a longitudinal section through tissue from a sunflower (Helianthus) plant, showing sieve tubes (horizontal structures) and sieve plates (red areas) in phloem tissueCredit: BIOPHOTO ASSOCIATES/SCIENCE PHOTO LIBRARY

Mitosis in plant root. Confocal light micrograph showing epidermal cells of a plant root. The cell walls can be seen in red. Chromatin in the nucleus (green) of one of the cells has separated (centre left) during the late anaphase stage of mitosis (nuclear division). Fluorescent dyes have been used to highlight the cell structures and proteins. This root is from the Arabidopsis thaliana plant.Credit: DR JOHN RUNIONS/SCIENCE PHOTO LIBRARY
Cell division. Immunofluorescent light micrograph of a human epithelial cell (centre) during the interphase stage of mitosis. Mitosis is the cycle of replication and division by which new body cells are formed. Here, the chromosomes of the parent cell (blue) have begun to duplicate and pair up, and the microtubules (green) have formed. Credit: DR TORSTEN WITTMANN/SCIENCE PHOTO LIBRARY
