There are 2 types of reproduction (in which a new organism gets chromosomes from its parent/ parents which contain a set of instructions called GENES) called Asexual reproduction and Sexual reproduction.
• It involves ONE parent, whose organism cells divide by Mitosis, the divisions create a new set of cells which conform an organism which will be EXACTLY THE SAME
• They reproduce using stem tubers, the tubers are planted underground, where many new plants will grow as whenever there is a bud a new plant can grow
1st the organism produces GAMETES, sperm in case of male and eggs in case of female.
2nd The two gametes join their nuclei and fuse together to create a new cell called ZYGOTE. (This process is called fertilization)
-It divides again and again and becomes an organism with a combination of genes from both parents, so the offspring is different from all the other organisms , even their parent’s one
– They are made of the division of ordinary cells called MEIOSIS. As they are an ordinary cell divided, they do not have 46 chromosomes as normal, they have 23 as when the two gametes join they can create a cell with the common number of chromosomes.
Cells are divided into :
– Haploid Cells -> Cells with 23 chromosomes
-Diploid Cells -> Cells with 46 chromosomes
