The volvox is a type of green alga that lives in freshwater ponds. Each spherical alga is actually a colony consisting of up to 20,000 cells. Volvox Cells
Volvox Colony
A colony of volvox behaves like one single organism, with an anterior and posterior end. In one of the regions, the eyespots are more developed.
This helps the colony swim toward a light source. How is the volvox similar to a multicellular organism?
O A. The cells provide structural support to the whole colony.
O B. The cells in the colony are all capable of photosynthesis and can make food.
O c. The thousands of cells making up the colony have identical characteristics.
0. D. The individual groups of cells within the colony perform different functions.

interphase

the period of cell growth when the cell synthesizes new molecules and organelles. the cell is not dividing and it constitutes the majority of the time spent in the cell cycle

prophase

changes occur in the nucleus and cytoplasm. the chromatin condenses to form structures (sister chromatids) visible with a light microscope and the mitotic spindle begins to form, but the nucleus is still in tact

prometaphase

the nuclear envelope fragments and the spindle microtubules attach to the kinetochores of the sister chromatids

metaphase

all the cell's duplicated chromosomes are lined up at an imaginary plane equidistant between the poles of the mitotic spindle

anaphase

begins when sister chromatids separate from each other and ending when a complete set of daughter chromosomes arrives at each of the two poles of the cell

telophase

the daughter nuclei form at the two poles of a cell

cytokinesis

the division of a cytoplasm to form two separate daughter cells. usually occurs during telophase during mitosis. this and mitosis make up to mitotic (m) phase of the cell cycle
