internal assessment germination

Extracts from this document...

Introduction

aIntroduction During seed germination, food stored in cotyledon of seed will be used as a source of energy and raw materials to build new cells. This leads to the decrease in mass of the seeds. The mass will start to increase once the plant is able to conduct photosynthesis as it will start to form shoots and roots. Aim To determine the relationship between seed germination and changes in mass of the seed. Research Question How does the germination process affect the mass of the seed? Hypothesis If the germination process occurs, there will be changes on the mass of the seed. ...read more.

3) Presence of oxygen - because they are placed at the same spot, they will obtain the same quantity of oxygen. 4) Light intensity - placed at the same place, both of the set is having the same light intensity throughout the experiment. 5) Distance between the seed - in order to make sure the competition rate between the seed is minimum; they are placed at equal distance from each other in both set of experiment. Materials and Apparatus Materials Quantity Red beans 50 Tap water - Cotton wool - Apparatus Quantity Microwave oven 1 unit Beaker, 500ml 2 unit Petri dish 2 unit Electronic balance 1 unit table 1; the materials and apparatus needed Method 1. ...read more.

7. Place the beans from petri dish A and B inside a microwave oven for 20 seconds at 300c. 8. Measure and record their respective mass using an electronic balance. 9. Repeat step 6 - 8 each day. Make sure that the cotton wool inside petri dish A is always moist. Data collection Petri dish condition Dry mass of 3 beans, gram � 0.0001g 1st day 2nd day 3rd day 4th day 5th day 6th day 7th day A Beans are soaked and placed on moist cotton wool B Beans are not soaked, without moist cotton wool.

  2. internal assessment rate of transpiration

    The air spaces are always nearly saturated. The lower the humidity outside the leaf, the steeper the gradient and therefore the faster rate of transpiration. 4. Rate of transpiration is directly proportional to speed of the wind. Referring to graph 3, the higher the wind speeds, the faster the rate of transpiration.

    gibberellic acid to be produced and as the seed absorbs water and swells the testa will begin to crack. Gibberellic acid in tern causes the synthesis of amylase, which breaks down the starch contained within the cotyledon into maltose. The maltose can then be hydrolysed to glucose for respiration of polymerised to form cellulose, necessary for plant walls.
