The chemical formula for photosynthesis is 6CO2 + 6H20 + (energy) → C6H12O6 + 6O2. In English this is carbon dioxide + water + sunlight "yields" glucose and oxygen. This is how plants and photosynthetic organisms release oxygen.
The chemical formula for cellular respiration is pretty much the reverse of that. C6H12O6 + 6O2 --> 6CO2 + 6H2O + ATP. This translates to glucose + oxygen “yields” carbon dioxide, water and ATP (usable energy). This is why we (and animals) breathe out carbon dioxide.
Glucose is a type of simple sugar.
As for mitosis, it is the division of somatic (typical tissue cells) cellular reproduction. A single cell with “2n” number of chromosomes (diploid) creates two identical copies of itself (daughter cells, also 2n and diploid) to perform the same function as the original cell. The chromosomes are exactly the same.
a. Interphase – The DNA of the parent cell is replicated.
b. Prophase – The chromosomes condense and are visible; nuclear envelope breaks down.
c. Metaphase – The chromosomes align at the metaphase plate (made up of two sister chromatids), located center cell, attached to spindle fibers which attach to centrosomes
d. Anaphase – The chromatids are pulled apart toward opposite poles of the parent cell
e. Telophase – Chromosomes are now at opposite poles and decondense, while the nuclear envelopes rebuild and spindle fibers break down
f. Cytokinesis – In animals, a cleavage furrow aids in separating the diploid daughter cells; in plants, a cell plate separates the daughter cells. There are now two cells where originally was only one.
