CLASS: 10^th     SUB: Biology (Summer Vacation Homework)          CH: Life Processes

GENERAL INSTRUCTIONS a)      Questions should be attempted in a sequential manner and a line to be drawn after each question. b)      Present your work neatly. c)       Holiday Homework should be done in Bology Class-Work Notebook. It will be marked 10 in Internal Assessment of FA-2 Biology.

READ THE EXTRACTS AND ANSWER THE QUESTIONS WHICH FOLLOW

(A)          Villi

There are several thousand villi in every square centimetre of the lining of the small intestine. The cells in the lining of each villus have folds called microvilli on their outer surfaces. One of these cells is shown magnified in the diagram.

Explain the way in which the structure of the villus enables the products of digestion to be absorbed efficiently.

Mucus is produced by some cells in the lining of the stomach.
One function of mucus is to protect the lining of the small intestine against the action of certain chemicals.

(a) Give the name of one type of chemical present in the stomach which would otherwise damage the lining.

 (b) Suggest one other function of mucus produced in the small intestine.

 

(B) 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 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 colors in the color spectrum, and reflects only green and yellow wavelengths of light. This is why we see leaves as green or yellow - because these colors are reflected into our eyes.

1. What is photosynthesis?

2. Where does photosynthesis occur?

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?

(C) Photosynthesis

Glucose is another name for sugar. The molecular formula for glucose in C₆H₁₂O₆. 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

This formula says that carbon dioxide and water molecules are combined with the energy from sunlight to produce sugar and oxygen. The reactants in photosynthesis (what is used) are CO₂, water and sun. The plant gets water from the ground through its roots. The plant collects carbon dioxide from the air. Much of the carbon dioxide comes from living organisms that exhale it, but some also comes from factory smokestacks and car fumes The products (what is made) are glucose and oxygen. The glucose produced is used by the plant for energy and growth. We also use this glucose by eating plants. The oxygen produced is released into the air for us to breath. Photosynthesis is essential for all life on earth, because it provides food and oxygen.

7. What is the formula for photosynthesis?

8. What three things are used to make glucose in photosynthesis?

9. Where does the water come from?

10. Where does the water enter the plant?

11. What are some sources of C0₂?

12. What type of energy does the plant use to convert C0₂ and H₂0 into sugar?

13. What is produced in photosynthesis?

14. What is the glucose used for?

15. What is the oxygen used for?
