Web31 okt. 2024 · Cell division and cell enlargement is used by multicellular organisms to grow and reproduce. Plants can also grow via differentiation into branches, leaves, etc. From the moment of fertilisation cell division begins, when the zygote replicates itself exactly through mitosis. How does cell division increase the potential for growth? WebThe 40 weeks of pregnancy often are grouped into three trimesters. Here’s how the trimesters are defined: First trimester (first day of LMP to 13 weeks and 6 days): The time when fertilization and major organ development occurs. Second trimester (14 weeks and 0 days to 27 weeks and 6 days): The time of rapid growth and development.

Web14 nov. 2014 · Plant cell walls enlarge more rapidly at low pH (‘acid growth’), a process that is mediated by nonenzymatic proteins named α-expansins. Several classes of enzymes modify the structure of pectins and hemicelluloses in the cell wall, but it is not clear whether such activity modulates growth in most cases.
