Biology

Biology plus kids have a 16 page EOC review packet. Coach P has been absent for 2 days and their assignment has been to create 2 questions from each page for a total of 32 questions. Any help with this is appreciated!!😀

Biology

Biology Plus students were given a Cell Vocabulary sheet with questions and answers. Please start reviewing the words with them in preparation for EOC. Thanks

The students were instructed to find definitions of the following words:

1. Allele- one of two or more alternative forms of a gene for a particular trait

 

2. Dominant- gene that produces the same phenotype in the organism whether or not its allele identical

3. Genetics- science of heredity

 

4. Phenotype- observable characteristic that is expressed as a result of an allele pair

 

5. Genotype- an organism’s allele pairs

6. Heterozygous- organism with two different alleles for a specific a trait

 

7.  Homozygous- organism with two of the same alleles for a specific trait

 

8. Hybrid- organism heterozygous for a specific trait

 

9. Recessive – a specific trait that is hidden

Bell Work- Describe what is happening to the cell during:

Telophase- Start to see 2 cells forming; cell “pinches” in the middle. The “pinched” part is called a cleavage furrow. Cell still together;

Cytokinesis- 2 cells separate when their cytoplasm divides. 2 cells

 

Students took the Standardized Test Practice in the Biology book on pg 264.

If they have a phone or computer going to “student.loretto.org” can access the book.  For this particular lesson they googled- “chapter 9 student.loretto.org”.

Photosynthesis Notes Continued:

 

What are the 2 types of reactions in photosynthesis?

1. The first reaction is called Light-Dependent (occurs in the thylakoids).

 

Note:  Light-Dependent- needs sunlight

 

2. The second reaction is Light- Independent(occurs in the stroma).

 

Note: Light-Independent- Alone; by itself; Light –independent- doesn’t need sunlight. The 2nd reaction does not need sunlight. The reaction can happen without light. 

 

What do electron carriers do?

Sunlight makes electrons in the chlorophyll (located in the thylakoids) very excited!

 

What does the NADPH do?

The NADPH carries the very excited high-energy electrons to reactions in the cell.

 

Cycle?

The Calvin Cycle uses ATP and NADPH from light-dependent reactions to produce high-energy sugars (FOOD)

Bell Work- What is the important molecule that is produced by Photosynthesis?

Glucose = sugar (C6H12O6) ; Oxygen also.

 

Students did a read aloud and then answered 3 questions.

1. What do you call the folded part inside the Mitochondria?

Cristae- layered structures created by the inner membrane, which is folded over many times.

 

2. Why are Mitochondria important?

Mitochondria are the powerhouse of the cell. Mitochondria are the working organelles that keep the cell full of energy.

 

3. What type of cells need many Mitochondria?

Muscle cells need many mitochondria because they need a lot of energy.

Biology Plus Notes- January 6, 2016

 

Bell Work- 

1. In what cell part does Photosynthesis occur? 

Chloroplast

 

Questions 2-7 will be answered in the article they will read today.

2. What do the Chloroplasts do with light energy?

Chloroplasts work to convert light energy of the sun into sugars that can be used by cells.

 

3. What is something that plants release?

Plants release oxygen.

 

4. How many membranes does a Chloroplast have?

Chloroplasts have 2 membranes that protect the inner parts of the chloroplasts.

 

5. What do Chlorophyll molecules do?

Chlorophyll molecules sit on the surface of each thylakoid and capture light energy from the sun.

 

6. What do the lamellae do for the Chloroplast?

Lamellae act like the skeleton of the chloroplast, keeping all of the sacs a safe distance from each other and maximizing the efficiency of the organelle.

 

7. What is the whole purpose of Photosynthesis?

Photosynthesis is the process of a plant taking energy from the Sun and creating sugars.

Bell Work- Write a paragraph describing your break. What did you do? Who were you with? Did you get anything nice?

Students then shared their paragraphs.

 

Topics to be covered during 2nd semester:

1. Photosynthesis (Chloroplast)

2. Mitochondria (Cellular Respiration)

3. Mitosis (cell division)

4. Meiosis (sex cells division)

5. Genetics

 

During 2nd period Coach P will start notes.

Biology Plus Notes- Dec. 11, 2015

 

Every student has a Biology Review.  They need to try to answer questions 1-30 (skip 28-29).  They can go to Ferrell Blog for a Biology EOC Review. 

 

Students are working on answering questions 1-30 now. Some completed this yesterday. 

Coach P is giving the answers. He is explaining all the questions.  Students should be copying the notes as Coach P is writing them on the board. (Josh is not cooperating!)

1. A.  Combine- put together; Compound- more than one part;

2.  A.  Valence- Outer energy level

3.  A. Mono-1, saccharide-sugar= carbohydrates

4.  A. Stores and transmit heredity- DNA, RNA, Nucleic acids

5.  C.  Poly=many; simple=NAH; glycerol is not made of fatty acids; RNA is made of nucleotides. Amino acids are not made of proteins. 

6. A. Product

7. D. If something combusts, something is burned.  

8. B. Enzymes work outside of the cell. Enzymes speed up chemical reactions. 

9.  A.  A substance that accelerates the rate of a chemical reaction- Catalyst= speed up

10.  B. Enzymes speed up

Bell work- Use your cell diagram (pictures) to do the following:

I am an organelle that “traps” energy from sunlight. 

I have a pigment inside which makes me appear green.

What organelle am I? 

Chloroplast

 

Plants absorb nutrients from the soil to make their food.  

Chloroplast traps energy from the sun. 

Photosynthesis= Glucose

 

Exam Review:

Golgi Body (Golgi Apparatus) (looks like a wifi symbol)-packages and distributes proteins. It is like UPS, Fed Ex… Golgi is away from the nucleus.  More than one can be in a cell. 

 

Note: Students should have 13 cell parts and functions on their sheet. 

 

Centrioles- Centrioles are only seen in the animal cells.  The Centrioles work in cell division. 

They are cylindrical (shaped like a soda can).  

 

Nucleolus makes the ribosomes that make the proteins in the nucleus. 

 

Note: Animal cells are circles.  Plant cells are rectangles.

 

Cytoskeleton: Cyto = cells; Skeleton=Bones

Cytoskeleton is the bones of the cell. It gives the cells structure. They are pieces inside the cell responsible for keeping the cell shape and structure.

 

Cell Wall: Only in plants and bacteria; The cell wall is rigid (stiff, firm) outer covering which protects the cell and provides structure. That is why plants stay still. They don’t run away from predators. They need to stay still and protect themselves.

Bell Work- The students copied a diagram of the 2 major types of cells: Prokaryotic and Eukaryotic.

Prokaryotic cells- Bacteria and Archea

Eukaryotic cells- Plants, Animals, Fungi, and Protists

 

Biology Plus Notes- Dec. 8, 2015

 

Bell Work- What does the Golgi Body do for a cell?

Golgi Body packages proteins into vesicles (bubbles) to move to other parts of the cell. 

 

Students should have definitions for the following:

Cell Parts: Functions (jobs)

1. Nucleus- “Brain” – controls other cell organelles

2. Endoplasmic Reticulum- ER are both Smooth – storage lipids, steroids and Rough-  rough have ribosomes and helps assemble proteins.  

3. Vacuole- “Bubble”- stores water, food, and nutrients

4. Chloroplast- Traps energy from sunlight for photosynthesis

5. Cytoskeleton- helps support structure of the cell

6. Golgi Body- Packages proteins into vesicles (bubbles) to move to other parts of the cell.

7. Nucleolus

8. Cell Membrane

9. Centrioles

10. Mitochondria

11. Lysosome

12. Ribosome

13. Cell Wall

 

 

Biology

Students continued labeling and coloring the plant and animal cell diagrams

Biology

Biology Plus Notes- Dec. 4, 2015

 

Bell Work- What are the main functions of the Lysosomes in a cell? Lys- to loosen; to cut

Inside the lysosome there are enzymes; the lysosome is like a bubble. The lysosome takes the enzyme out.

The lysosomes break down foreign objects or broken cell parts.

 

Students were given computers. They did a search for “plant cells.”  

Plant cells are like a rectangle. They are green. It is green because of the chloroplast.  Every time the chloroplast is drawn, it needs to be green.

 

The students were computers and diagrams of plant and animal cells. They were to label the parts of the cells and color them.
