Q4. ACTIVITY 1

Think about:

I) How you will exercise and how long for, how you will measure your pulse and when you will need to take

you pulse. How will you know what your recovery rate is?

II) How much time does it take for a person’s heart to return to its resting heart rate after vigorous exercise?

Do this activity with a member of your family

Procedure – Determining resting heart rate:

1. Sit at ease for two minutes.

2. Take your pulse. (Or your partner can take your pulse.) Count the number of beats for 15 seconds and

multiply by 4. Do this three times. Record this data in the data chart on the next page.

Q6. READ THE EXTRACTS AND ANSWER THE QUESTIONS WHI CH FOLLOW

(A) Chloroplasts

Photosynthesis is a process in which sunlight energy is used to make glucose. The site of photosynthesis is

in the chloroplast - an organelle found in the leaves P"'I C." Chloroplast of green plants. The main functions

of chloroplasts are to produce Food (glucose) during photosynthesis, and to store food energy.

Chloroplasts contain the pigment, chlorophyll. Chlorophyll absorbs most of the colours in the colour

spectrum, and reflects only green and yellow wavelengths of light. This is why we see leaves as green or

yellow - because these colours are reflected into our eyes.

3. What are chloroplasts and where are they found?

4. What are the two main functions of chloroplasts?

5. Why do most leaves appear green?

6. What is the primary pigment found in the chloroplast?

Photosynthesis

Glucose is another name for sugar. The molecular formula for glucose in C6H1206. Plants make sugar by

using the energy from sunlight to transform CO2 from the air with water from the ground into glucose. This

process, called photosynthesis, occurs in the chloroplast of the plant cell. During this process, oxygen (02) is

created as a waste product and is Released into the air for us to breath. The formula for photosynthesis is:

C02 + H20 + sunlight ---- C6H1206 + 02
