Plant Reproduction and Development Chapter 27 Flowers Basic Concepts reproductive structures of angiosperms monoecious vs dioecious monoecious each flower has both male and female structures. What is asexual reproduction. ?. Asexual reproduction. is a mode of reproduction by which offspring arise from a single parent, and inherit the genes of that parent only, it is reproduction which does not involve . The process of making new individuals (offspring) from existing individuals (parents).. ASEXUAL REPRODUCTION. :. Asexual . reproduction is reproduction . without gametes. .. Gametes are the male and female sex cells. . Aphid’s(. macrosiphummiscaniti. ). Kingdom-. animalia. Phylum-. arthopoda. Class- . insecta. Order- . hemiptera. Suborder-. sternorrhynch. Superfamily-. arphidoidea. A. phid’s :– Plant lice or Green flies or White flies.. 1. Make a Venn Diagram. 2. Asexual Reproduction. Sexual Reproduction. Both. Types of reproduction in living organisms. Asexual Reproduction. Requires only one parent. Offspring have 100% the same chromosomes as the parent.. Modern cell theory. Keep in mind that:. All living things are made up of one . or . more cells.. The . cell . is . the basic unit of life.. All cells come from preexisting cells. Just as cells reproduce as part of the Cell Cycle, living organisms reproduce as part of the life cycle.. Reminder:. Mitosis. Meiosis. Forms sex cells (sperm and eggs). ½ the number of chromosomes compared to the parent cell. Genetically identical to parent cell. Responsible for growth, differentiation, and asexual reproduction. Reminder:. Mitosis. Meiosis. Forms sex cells (sperm and eggs). ½ the number of chromosomes compared to the parent cell. Genetically identical to parent cell. Responsible for growth, differentiation, and asexual reproduction. Sexual vs. asexual reproduction. Sexual reproduction in plants. Gametophytes and sporophytes. Gymnosperms and angiosperms. Asexual reproduction in plants. Asexual reproduction using fragments. Asexual reproduction using special structures. Binary Fission. Bacteria reproduce by a process called binary fission. Binary fission: a copy of their single chromosome is produced and then the cell divides in half so that one half gets one chromosome and the other half gets the other chromosome. Introduction to asexual and sexual reproduction in plants. Year 5. Age 9-10 . For parents. Thank you for supporting your child’s learning in science.. Before the session:. Please read slide 2 so you know what your child is learning and what you need to get ready.. B1.7.2. Friday 9. th. January 2015. All cells (excepts sperm/egg) contain . ___ chromosomes.

Longest phase. Growth and development of cell. Interphase. Cell prepares to divide. Spindle Fibers appear. This fusion of gametes is called fertilisation. . Sexual reproduction allows some of the genetic information from each parent to mix, producing offspring that resemble their parents, but are not identical to them. In this way, sexual reproduction leads to variety in the offspring. Animals and plants can reproduce using sexual reproduction.. Katerina . Dadakova. , Department . of. . Biochemistry.
