8. PLANT CELL

9. Cell wall-protections & gives shape Cell membrane-regulates balance between cell & the environment Cytoplasm-constanly moving gel mixture inside cell membrane that contains heridity material Nucleus- controls all the activities of the cell and contains heridity material.(proteins & DNA)

10. Mitochondrion-breaks down lipids & carbohydrates. Ribosome- structure in which cells make their own protein Endoplasmic reticulum(ER)- moves materials around in a cell. (smooth & rough) Golgi bodies-package cellular materials and transport them within or out of cell.

11. Osmosis-a type of passive transport that occurs when water diffuses through a cell membrane. Diffusion-a type of transport when molecules move from an area where there are more of t them to fewer of them.

18. The study of heredity started with the work of Gregor Mendel and his pea plant garden Mendel was an Austrian Monk that lived in the mid 1800’s

19. Mendel’s cross between tall pea plants yielded all tall pea plants. His cross between small pea plants yielded all small pea plants. Mendels’ cross between tall pea plants and small pea plants yielded all tall pea plants. X = x = X =

20. Mendel then crossed these second generation tall pea plants and ended up with 1 out 4 being small. x =

21. Mendel’s work led him to the understanding that traits such as plant height are carried in pairs of information not by single sets of information. -Carrying the information are chromosomes. -Chromosomes are made up of sections called genes. -Genes are made up of DNA

22. DNA D.N.A. - Deoxyribonucleic Acid Molecule made of: 1. Deoxy Sugar 2. Combination of four nitrogen bases Either:a. Guanine b. Cytocine c. Thymine d. Adenine The sum total of combinations that these four bases are capable of creating are greater than all the stars visible in the night time sky

23. DNA DNA is found in all living cells –It controls all functions inside a cell –It stores all the genetic information for an entire living organism –Single cell like an amoeba –Multi cell like a human

24. Genetics Small sections of DNA are responsible for a “trait”. These small sections are called “Genes”. –Gene - A segment of DNA that codes for a specific trait –Trait - A characteristic an organism can pass on to it’s offspring through DNA Gene

26. 1. Predict the offspring from a cross between a purebred tall pea plant and a hybrid tall plant. Use T for tall and t for short. (a) Give the genotypes. Purebred Tall = ____ Hybrid Tall = ____ (b) Create a Punnett square to determine the genotypes for the offspring. (c) What is the probability that a plant would be tall? _______ % (d) What is the probability that a plant would be short? _______ % 2. Predict the offspring from a cross between two hybrid tall pea plants. (a) Give the genotype for a hybrid tall plant. ______ (b) Create a Punnett square to determine the genotypes for the offspring. (c) What is the probability that a plant would be tall? _____ % (d) What is the probability that a plant would be short? _____ % (e) If you were to plant 100 seeds from this cross, how many would you expect to be tall?
