Cycle 4: July the 29th to August the 5th

Hi guys:

This cycle we will compare Aerobic and anaerobic respiration processes and we will have a Quiz related to Respiration and photosynthesis concepts ( in the second class of the cycle).




If you really want to understand Cell Respiration, check this animation and answer the questions within all the four short presentations.

Print and bring the worksheet

Cycle 3: July the 22nd to 28th

Hi guys:

In this cycle we will work on Celluar respiration and we will compare it to Photosynthesis.

Follow the instructions

1. Watch this video to start with the concept basis: Notes are no necessary.



2. Read the following information and draw (or print), and color chloroplast and mitochondria as the text ask to you. For points


CHLOROPLASTS AND MITOCHONDRIA


Chloroplasts are double membrane organelles with a smooth outer membrane and an inner membrane folded into disc-shaped sacs called thylakoids.  Color and label the outer membrane light green.  Thylakoids, containing chlorophyll and other accessory pigments (red, orange, yellow, brown), are in stacks called granum (grana, plural). Color and label the grana (STACK) dark green in Figure 1.  Grana are connected to each other by structures called lamellae, and they are surrounded by a gel-like material called stroma.  Color and label the lamellae brown in figure 1.  Color and label the stroma light blue in Figure 1.

FIGURE 1-CHLOROPLAST




Mitochondria are the powerhouses of the cell because they “burn” or break the chemical bonds of glucose to release energy to do work in a cell.  Remember that this energy originally came from the sun and was stored in chemical bonds by plants during photosynthesis. Glucose and other carbohydrates made by plants during photosynthesis are broken down by the process of aerobic cellular respiration (requires oxygen) in the mitochondria of the cell.  This releases energy (ATP) for the cell.  The more active a cell (such as a muscle cell), the more mitochondria it will have.  The mitochondria are bout the size of a bacterial cell and are often peanut-shaped.  Mitochondria have their own DNA and a double membrane like the nucleus and chloroplast.  The outer membrane is smooth, while the inner membrane is convoluted into folds called cristae in order to increase the surface area

    Color and label the outer membrane pink and the cristae red on figure 2.  This greatly increases the surface area of the membrane so that carbohydrates (simple sugars) can combine with oxygen to produce ATP, adenosine triphosphate (the energy molecule of the cell).  The electron transport chain takes place across the membranes of the cristae (crista, singular).  Inside the folds or cristae is a space called the matrix that contains enzymes needed for the Kreb's Cycle?  Color and label the matrix yellow on figure 2.

3. Finally, print the Worksheet for this cycle, please.

Cycle 2: july 15th to 21st

Hi guys:

This is our second cycle:

In this week we will design a power point presentation about comparisons between organ systems in different groups of organisms.


Watch this video and learn why is important understand tissues and body systems characteristics, and why is important stablish comparisons between them. Notes are not necessary.



In this Cycle we will design a Photo album in which you are going to:


Understand the basic function of some body system.
Sketch some systems in some vertebrate classes.
Find the common elements of the system that are in all classes.
Find the elements that are unique to a particular class.

Understand how do the body features help this creature survive in his ecological niche?

We are going to work in the computers in a Power point presentation to answer the previous
questions and using some body system´s images


Let´s make a short exercise: Observe the image and answer the questions in your notebook


Why does a frog have no ribs?
Why are the toes and fingers (phalanges) so long?

Why is the trunk so short and the legs so long?




See you on class!!!!
