What makes bacteria different from the protists listed above?

(Hint: Look at the characteristics you just listed)

______protist are eukaryotic; bacteria are all prokaryotic ______

Objective 5: You will be able to identify the parts of a plant and identify the adaptation this part provided that enabled plants to survive on land.

Assignment: State the adaptation that each plant part provides for the

plant’s survival on land.

Plant Parts

1. Cuticle – waxy layer that holds in moisture (keeps it from drying out)

2. Stomata – Pore like opening to allow for gas exchange

3. Vascular Tissue – movement of liquids through the plants

a. Xylem – Up à Roots to leaves; carries water

b. Phloem – Down à Leaves to roots; carries sugar

4. Leaves – Trap sunlight – site of photosynthesis

5. Roots –anchor plant to ground & absorb (take in) water and minerals

6. Stems – support leaves and flowers

7. Flowers – attract pollinators for reproduction

Assignment: Provide examples of each plant type listed below.

Plant Types

8. Nonvascular: mosses and liverworts

9. Vascular Seedless: Ferns

10. Gymnosperms: Pine Trees (produce cones)

11. Angiosperms: Any flowering plant (produces seeds)

Objective 6: You will, when given data be able to construct, read and interpret a graph.

Assignment: Complete the following graphing exercise.

Figure 2

Objective 7: You will, when given data be able to identify methods of reproduction for all kingdoms.

Assignment: Complete the following reproduction table.

Methods of Reproduction

Complete the following chart using the organisms listed below. Use each organism once.

Method of Reproduction / Page number
in book / Organism
Regeneration / 1.  Starfish
Conjugation / 2.  Paramecium
Alternation of Generations / 3.  Azalea (plant)
Binary Fission / 4.  Bacteria
Budding / 5.  Hydra
Metamorphosis / 6.  Grasshopper & Butterfly
Spores / 7.  Bread Mold

Organisms Word Bank:

Butterfly, Grasshopper, Bread Mold, Starfish, Azalea (flower), Bacteria, Paramecium, Hydra

Objective 8: You will be able to complete a punnett square to find the genotypic and phenotypic ratio and probability.

Hitchhiker’s thumb

Normal thumb Hitchhiker’s thumb

Being able to bend the top portion of the thumb backward is a recessive trait called a hitchhiker’s thumb. The dominant trait is to have a normal thumb. Diagram a cross for two individuals that are heterozygous.

1.  What is the parents’ genotype? Hh and Hh

2.  What is the parents’ phenotype? Normal

3.  What is the genotypic ratio? 1:2:1 à 1 homozygous dom: 2 hetero: 1 homozygous recessive

4.  What is the phenotypic ratio? 3:1 à 3 normal (dominant expression): 1 hitchhikers

5.  What is the probability of producing a child with a hitchhiker’s thumb?
25% or ¼

Folded hands

When folding your hands, if the left thumb crosses over the right thumb you show the dominant trait. If the right thumb crosses over the left thumb you show the recessive trait. Diagram a cross for one parent who is heterozygous for crossed thumbs and the other crosses the right thumb over the left thumb.

1.  List the genotypes for the parents. Rr X rr

2.  What is the genotypic ratio? 2:2à 1:1 à 50-50 shot

3.  What is the phenotypic ratio? 2:2à 1:1 à 50-50 shot

4.  What is the probability of producing a child who crosses the right thumb over the left thumb? 50%

Objective 9: You will be able to label diagrams showing the central dogma of protein synthesis.

Protein Synthesis is divided into two processes.

Words to use: Nucleus, Ribosome, Transcription, Cytoplasm, Translation

41. Process 1- ______Transcription_____-mRNA is made by copying the code from a DNA molecule.

42. This process occurs in the ____nucleus______.

43. Process 2-______translation______- a protein is assembled from amino acids.

44. This process occurs in the ______cytoplasm______at a ______ribosome______.
