Let's remember previous learned concepts...

Life Cycle • All living organisms go through stages in their lives. Example of stages: birth and dead. • In between these two stages many or few changes happen. • The process happens again in the next generation, and so on. • A life cycle describes all the stages in a living organism’s development from one generation to the next.

Reproduction • A cycle has no beginning and no end. • However, in living organisms, the stages include birth, and later, may include reproduction. • Reproduction is a process that a living organism uses to produce more of its own kind. • The changes between birth and reproduction varies from one organism to another.
8
How do Organisms Reproduce? • All organisms reproduce, but not through the same way. • Animals reproduce in two basic ways: sexually and asexually. • Asexual reproduction occurs when one cell divides into two cells, with the same amount and type of information. • Sexual reproduction occurs when a sperm cell from a male and an egg from a female join to make a fertilized egg.
9
MITOSIS
SEXUAL REPRODUCTION SEXUAL REPRODUCTION MEIOSIS
10
Asexual Reproduction • Asexual reproduction is much simpler, it doesn’t involve a sperm and egg. • Many invertebrates use asexual reproduction to produce offspring. • If a piece of a sponge falls off, it can grow into a new adult sponge, this is called regeneration. • Others like anemones and sea corals reproduce asexually by splitting in half. • Hydras, form a bud (budding) that falls off to become a new hydra.

Cell Cycle • Cells also have cycles, different stages happening in a specific sequence and under certain conditions. • As any other life cycle, it starts by birth (New cell), growth (G1), preparation (S), development and maturation (G2) and reproduction (Cell Division).
13
14
15
MITOSIS
• All cells use mitosis at one point or another. • Mitosis is a type of cell division where two cells (daughter cells) are generated from one single cell. • The daughter cells are identical copies of the original one, with the same genetic information. • The daughter cells are clones. • Mitosis has 4 stages: PROPHASE, METAPHASE, ANAPHASE and TELOPHASE. • These stages are continuous and are regulated by proteins and specific events in and out of the cell.
16
17
MEIOSIS • Meiosis is a type of cell division, however, it is used only by organisms that go through Sexual Reproduction. • Meiosis is a process with 2 divisional stages, each of these stages contain the same sub‐stages as in Mitosis: Prophase, Metaphase, Anaphase and Telophase. • These stages and sub‐stages are usually not continuous, but they are sequential.
18
19
Growth and Development • After birth, humans go through infancy and childhood, followed by adolescence and finally, adulthood. • Many other kinds of animals develop into completely different forms as they grow through their life cycle, this is called metamorphosis. • Examples: tadpoles develop legs and lungs while becoming frogs; butterfly larvae form a cocoon, from where a butterfly arises.

Group Assignment • The Class will be divided in 10 groups of 3 students each, selected randomly. • There are 10 different topics, one topic will be randomly assigned to each group. • Each group must investigate its topic and present a 3‐ minute video or 15‐slide presentation, as visual support. • Each member of the group must give a 2‐minute oral presentation. Reading during the presentation is not allowed. • Deadline: Monday, August 17th.
