The right option is C: prophase

Prophase is the phase of the cell cycle Ryan is observing.

Prophase is the first stage of mitosis during which the chromatin condenses to form the visible chromosomes. Also, a structure known as mitotic spindle which is composed of long proteins (microtubules) begin to form from the opposite ends of the cell (centrosomes) and a part of the nucleus where ribosomes are produced disappears during this phase.

All eukaryotic cells contain mitochondria. What does this mean?
Nikolay [14]

Answer:

Mitochondria- often called the powerhouses of the cell — enable eukaryotes to make more efficient use of food sources than their prokaryotic counterparts. That's because these organelles greatly expand the amount of membrane used for energy-generating electron transport chains.
