Bearded iris plants require a lot of sun and a mediocre amount of water. They thrive in neutral pH soil and is quite sensitive to insects/pests. The biggest improvement that can be made in the plant nursery to further their growth is to have the sufficient amount of watering but most importantly, adjust the greenhouse so that there is more sunlight entering the enclosure/ there is more lighting in general (long day setting).
1) Interphase is the longest phase and most of the cells are present in that very stage !!
2) Interphase is the longest phase and Anaphase is the shortest phase !! Interphase is the longest phase as in this phase the cells prepare themselves for dividing and it takes most of the time for gathering energy for division ; in this phase DNA also replicate !!
3)
Interphase: DNA replicates;
Prophase: Nuclear membrane starts disappearing and Centrioles go on opposite poles !! DNA condense to form Chromosome.
Metaphase: Chromosome attach to spindle fibre and starts to move to equitorial plate.
Anaphase: Centromere divide and half the chromatid goes on either pole
Telophase: Nuclear membrane starts to reassemble; Chrmosome goes to normal uncoiled state ; Other organelles starts appearing
Cytokinesis: Cell furrow forms and cell divides into two half.
4) In dividing cell nucleus membrane is absent while in non dividing cell the membrane is intact
5) Tip of the onion root is meristamatic cell which divides but if it is permanent cell ; there would be no division !!
Introduction to the outer condition and conceivable cancer-causing agents and, or the fast rate of mitosis that would enable malignancy to spread rapidly.
The skin has body securing capacities, it shields the interior organs from the introduction of the outer condition. It likewise pieces infections and other hurtful substances.
