Please start the chapter on Cancer p 1.29 in the textbook. Also start on p1.30 with the Meristematic tissue.

As always do a mindmap/summary after completion. Activity will follow

4 June

Please study the work on p1.31 regarding the permanent tissue. Make sketches of the epidermis, structure of the root hair, and guard cells of a stoma in your workbook.

Also start with p1.32 Parenchyma, Schlerenchyma and Collenchyma. Draw the sketches with labels in your workbook. Do not start vascular tissue yet. We’ll do that tomorrow.

8 June

Page 1.32 – Vascular tissue.

Xylem Vessels – draw the basic structure of the xylem vessel (p1.33 top left). Take note that Xylem works like a drinking straw as water and mineral salts moves upwards in the Xylem . Also draw the 3 different types of xylem and the Tracheid.

Phloem – page 1.33 – draw the structure. Companion cells p1.34. Functions of phloem. Take note of the difference between functions of Xylem and Phloem. Like a highway everything traveling upwards can only be transported via Xylem. Everything traveling down can only be transported via the Phloem.

Below is a powerpoint of the work for today and last week. Please complete the class activities in the document, I will put the answers up tomorrow.

9 & 10 June

Sorry everyone. Yesterday I was unable to load anything. Therefore I’m loading yesterday and today’s work.

Animal tissues page 1.34 – Epithelial tissue – please make drawings of Squamous-, Cuboidal-, Columnar- and Cilliated epithelium. study specifically their functions. Do the class activity in the powerpoint presentation

Animal tissues p1.35 – Connective tissue. No drawings needed, but please study sketches on p 1.36 and 1.37. Make sure you are able to identify the structures on these sketches and can label them. Do the three class activities in the presentation below of Areolar- and Dense connective tissue and Cartilage

11 June

Animal tissues p1.37 – Connective tissue continued. Study the sketches of bone and blood on p1.37 and 1.38. Use the presentation to fully understand the differences in blood molecules and their functions. Complete class activities.

12 June

Animal tissues p1.39& 140 – Muscle tissue and Nerve tissue. Draw the sketches of Striated muscle fibre, Smooth muscle tissue, Cardiac muscle tissue, Sensory neuron, Motor Neuron. Complete class activities.

15 June

Mark all class activities of the past week. All answers will be below. On page 1.41-1.45 you will find indigenous knowledge systems(IKS) and biotechnology. Please make a summary of the work for yourself as they ask a lot of general knowledge questions of this work.

29 June

Sorry for the long absence everyone. I hope this gave everyone the opportunity to review what we have done so far and those who are behind to catch up.

We start on p1.45 with Organs

Make a sketch of the external structure of a leaf p1.46 as well as a sketch of the internal structure of a leaf in your book.

Do a mindmap of the internal structure of a leaf’s organs

30 June

Page 2.2. Draw the sketch on page 2.2 of the external structure of the root. On page 2.3 draw the cross section through a part of the dicotyledonous root showing the various tissues.

1 July

Page 2.4 draw the cross-section through a part of a young dicotyledonous stem showing various tissues.

Be able to identify the vascular bundle from the sketch you’ve made.

P2.6 draw all 3 sketches to indicate the progression of the secondary thickening

P 2.7 draw the cross section through a 6 year old stem (only the labeled sketch

2 July

P2.8-2.10 Uptake of water and mineral salts by the plant. Make a mindmap of each of the 3 stages from all todays work.

P2.9 Draw the route of water movement with lables

P2.10 Transpirational pull – no sketches to be drawn however you should be able to describe the process in both pictures.

6 July

P 2.11 Translocation of manufactured substances. Please make sure that you understand the process of transpiration. Also what effects the rate of transpiration. Today’s work ends on p2.13. you will se on the presentation that i swapped wilting and guttation.

Tomorrow we will be starting with p 2.15 Support systems in animals. Please make sure you bring your books to school.

7 July

8 July

I am putting up all the work that needs to be done until next week Tuesday.

Page 2.19 different specialized vertebrae. Take special note of the atlas and axis, how they fit together and their functions. You have to know the functions of the vertebra. The rib cage you don’t need to draw but you have to be able to label and name the functions

Page 2.20 The appendicular skeleton you have to be able to: Label of pectoral girdle and back view of pectoral girdle, draw the back view of the pectoral girdle in your book. Label the upper limbs describe the parts and name the functions, draw the upper limbs in your book.

Page 2.21 You have to be able to: Name pelvic girdle parts and describe, also describe the difference between a male and female pelvic girdle. Draw only one of the two pelvic girdles in your book. Name the parts of the lower limbs and draw the lower limbs in your book.

12 August

We are taking a look at page 2.34 – 2.35. You have to identify and specify which specialised conductive tissue play a role in which part of heart.

We are also taking a look at the structure of the lymphatic system p2.35-2.37. There is a whole lot of new terminology being used. make sure you understand the process and can describe it as well. At the end of the presentation is a table comparing blood, tissue fluid and lymph, make sure to copy this table into your workbooks.

Complete the activity that follows. Question 4 is a insight question. Remember we’ve already done plant tissues and now we’ve done animal tissues. I’ll Give you 2 days to answer this question. thereafter I’ll upload the corrections, please make sure you at least attempt this and then do corrections.

The work that is part of the pick up and go to be collected this afternoon, is revision. Start answering this after you are done with today’s work.
