Unit2 – Key area 4: Notes for Reproduction - Copy what is in bold and follow instructions DO NOT GLUE THIS SHEET ON YOUR JOTTER Reproduction Read the book 1/ Reproduction in animals In biology, sex cells are called g_________________. _______________ contain and carry only ________ set of the parental chromosomes (half of the genetic material), they are said to be ___________. ________________ is the fusion of the nuclei of the two haploid gametes to produce a z_________ (i.e. the first cell obtained from fertilization). The _____________ will then divide to form the _______________. In land mammals, fertilization takes place ___________________, i.e. the sperm is deposited ____________ the female body. In fish, fertilization takes place ___________________, i.e. the sperm is deposited ______ the eggs, _____________ the female body.. A/ Male reproductive system Copy and label the diagram below + copy and complete the table (make both bigger!). Part Penis Sperm duct Testes Function (In addition, you can also glue if you want the diagram from the hand outs) In males, the __________ is the male gamete. It is produced in the ______________ . It travels in the ___________ __________ before it reaches the _____________ which allows it to be released inside the _____________ of the female. B/ female reproductive system Copy and label the diagram below + copy and complete the table (make both bigger!). Part Vagina Uterus Oviduct (Fallopian tubes) Ovary Function (In addition, you can also glue if you want the diagram from the hand outs) In females, the _______ is produced in the ______________. Once a month, an egg is released in the _________ . It is in the _____________that the ovum meets the sperm and that _____________________ can take place to form the z__________. After the first division, the embryo travels down the oviduct until it reaches the ____________ where implantation (i.e. its burying into tissue) can take place. 2/ Reproduction in plants Read book Copy and label the diagram below + copy and complete the table (make both bigger!). Part Petal Stigma Ovary Nectary Anther Function P___________ is when a pollen grain is transferred from an ___________to a _________. After landing on the stigma, the pollen grain germinates, i.e. it grows a pollen tube which eventually reaches the__________. The male gamete travels down the pollen tube to fuse with the female gamete to form the ________ (Fertilisation) Copy the diagram below
