FACT IDEA LEARNING ISSUE ACTION PLAN

1. Farmers worry about the crops will not yield as usual because of the draught.

1. During draught, plant experienced extreme water deficiency.

2. Farmers use alternative ways to make sure that crop production not decrease because of draught.

1. Why the crops will not yield when draught season coming?

2. How yielding process of the plant occur?

3. What are the alternative ways to overcome the decreasing of yield?

1. Research from internet.

2. Search Botany books.

3. Refer lecture note Plant Physiology.

FILA CHART

ANSWER LEARNING ISSUES :

1. Why the crops will not yield when draught season coming?

• During draught, plant experienced extreme water deficiency. • As we know, plants need water to grow. • Without water, plants could not use energy from the sun to

photosynthesis.• Many other process also cannot take place when have lack of water. • Without water, plants would be unable to grow taller.  • Water is also needed to carry other nutrients from the roots to the

leaves and flowers.• Water is so important that plants that are native to desert conditions

will go to extraordinary lengths to hoard their water.• Example :   Cacti are filled with water, which is why most cacti are

covered with prickly spines to ward off any potential usurpers.

2. How yielding process of the plants occur?

•

2. What are the alternative way to overcome the decreasing of yield?

Farmer plant another plants that can stand with high temperature like bromeliads and cactus.

Farmer build many reservoirs by damming rivers and large-scale irrigations to make sure that there are the continuity of water supply for crops.

Build green house to provide and control the temperature surrounding for plant growth and development.

What is green house?????A greenhouse is a structure with a glass or plastic roof

and frequently glass or plastic walls for the cultivation and exhibition of plants under controlled conditions

Purpose of green house

• Not to imitate mother nature.• Take a good look around• Bugs eating the plants, unfavorable heating

conditions, and competition for nutrients are not in the plants' best interest.

• To improve upon nature and grow a plant to its optimum capacity.

Uses of green house• Protect crops from too

much heat or cold• Shield plants from dust

storms and blizzards• Help to keep out pests• Light and temperature

control allows greenhouses to turn inarable land into arable land

• For growing flowers, vegetables, fruits, and tobacco plants

• Crops for commercial production.

Let see the video!!!!

Farmer find out another place that suitable for plant growth that have enough water.
