Shows the process of human reproduction from conception to birth, filmed by Lennart Nilsson using endoscopic cameras placed inside the womb. (bufvc.ac.uk)
Spermatozoa , in simplest terms are male haploid gamete cells that form specifically for the reproduction process in the male body. (kelleemaize.com)
In this type of reproduction two haploid cells originated by meiosis, the gametes, that are united during the fertilization. (sd43.bc.ca)

During Interphase, the cell is preparing for the mitosis. (scienceabc.com)

However, if simplified, mitosis can be defined as the exact duplication of a cell where the daughter cells will have the same genetic information as the parent cell. (vedantu.com)
In meiosis, the daughter cells will only have half of the genetic information of the original cell. (vedantu.com)
Each of the four resulting daughter cells has a different genetic makeup. (scienceinschool.org)
Meiosis I - This process gives us two haploid daughter cells. (scienceabc.com)
This linkage ensures their correct segregation to the daughter cells later on. (scienceblog.com)

Eukaryotic cells are defined by their structural complexity, comprising numerous membrane-bound organelles that compartmentalize different cellular processes. (ashdin.com)
Known as the "powerhouses of the cell," mitochondria are responsible for energy production through cellular respiration. (ashdin.com)
Lysosomes contain enzymes that break down cellular waste, foreign substances, and damaged organelles in a process called autophagy. (ashdin.com)
