Which of the following happens during the inter phase
The cell grows.
Centrioles appear.
Spindle fibers begin to form.
Centromeres divide.
All of the above.
During the interphase of the cell cycle, several activities occur that are necessary to prepare the cell for cell division. Out of the options given, the correct answer is that the cell grows.
Explanation on how to get the answer:
1. The cell grows: During interphase, the cell undergoes growth and increases in size. This is the longest phase of the cell cycle, where the cell prepares itself for division by duplicating its DNA, organelles, and cytoplasm.
2. Centrioles appear: Centrioles are small cylindrical structures involved in cell division, specifically in the formation of the spindle fibers. However, centrioles do not appear during interphase. They are already present in the cell and participate in cell division during the subsequent phase, called mitosis.
3. Spindle fibers begin to form: Spindle fibers are protein structures that play a crucial role in cell division. They are responsible for separating the chromatids (the duplicated chromosomes) during mitosis. However, spindle fibers do not begin to form during interphase. They are formed during prophase, which is the first stage of mitosis.
4. Centromeres divide: Centromeres are structures that hold the sister chromatids (duplicated copies of chromosomes) together. However, centromeres do not divide during interphase. The division of centromeres occurs during the later stages of cell division, which is referred to as anaphase of mitosis or anaphase II of meiosis.
To summarize, out of the given options, only the cell growth occurs during the interphase of the cell cycle.
