Some, like mosses and ferns, reproduce by spores. Other plants, lik trees (gymnosperms), form seeds inside of cones. Flowering carded them. plants (angiosperms) like roses, oak trees and corn, form seeds that are encased in fruit. All seeds contain a plant embryo and endosperm, which is a food supply that contains all the neces in the regular trash. sary materials to begin to grow, given appropriate conditions. Seeds are covered by a tough outside coat, called the testa, that protects the seed from predation by bac- teria, fungi, or insects. The testa must be split in order for the plant embryo to germinate, or grow. reproduce by spores. Other plants, like pine and spruce mediately. Make sure note what happened and the date you dis a plant embryo Seeds and soil can be disposed of The embryo has three main parts: the shoot, the root, and the leaves. In angiosperms, the shoot (called the epicotyl) has one or two embryonic leaves (called cotyledons). The shoot is genetically programmed to grow up (away from the soil). The root (called the radicle) develops into the root system of the new plant, and is programmed to grow down (into the soil). The radicle is the first part of the new plant to emerge, breaking the testa open and allowing for the rest of the embryo to grow. When seeds are released from the parent plants, most are dry and almost dormant, but they are defi- nitely alive. Germination will occur given the right conditions of water, oxygen, light, and temperature. These conditions vary according to plant type PROCEDURE You will have to do some research to determine what aspect of seed germination and plant growth you would like to investigate. Your question must be testable: you will be conducting this experiment on your own, outside of lab. 93

Explanation / Answer

Brainstorming for Topic of Seed Germination-

Factors affecting seed germination-

1) Water -Seeds need water for germination

2) Optimum temperature- Seeds germinate in an optimal temperature range, cold temperature    prevents seed germination.

3) Light- Seeds need light to germinate

4) Oxygen- Seed need oxygen to germinate.

5) Soil- type of soil

6) Thickness of seed coat- Thicker seed takes longer to germinate than thinner seeds.

POTENTIAL RESEARCH QUESTION’S

1) How does seed coat affect duration of seed germination?

EXPERIMENT- Take 5 seeds with different type of seed coats. Measure the time taken to germinate by different seeds. Compare the time taken. Conclude whether the seed coat is related to time taken to germinate.

HYPOTHESIS- Seeds with thicker coat will take longer to germinate, because water and other nutrients will take longer to reach embryo. Seeds with thin coat will germinate sooner.

2) How does quantity water affect the germination of seed?

EXPERIMENT- Take 5 seeds of same plant, Give different quantity of water to each plant. Observe what happens to the seed in different quantities of water Let range be 1st seed with no water to 5th seed be completely soaked in water.

HYPOTHESIS- Dry seed will not germinate, Seeds given water in sufficient quantity will germinate. Excess of water might decompose the seed.

3) Is light needed for seed germination? Is artificial light good for seed germination and plant growth.

EXPERIMENT-Take 3 seeds of same plant. Keep one in darkness, Keep one in artificial light, Keep one in Sunlight. Notice which seed will grow best. Make sure all other factors of water, soil etc are same.

HYPOTHESIS- Seeds won’t grow in dark, seeds will glow at a slower rate in artificial light depending upon type of light (wavelength of light). Seed will grow best in sunlight.

4) Is oxygen needed for seed germination.?

EXPERIMENT-Take 5 seeds of same plant and bury them in soil of different depth. Record the growth of each seed and time taken to come out of soil layer. After specific time take out the plants and measure their height, is the growth hindered in seed which are buried too deep.

HYPOTHESIS- Seeds at more depth will not grow or grow very slowly because air is needed for seed germination.

5) Does soil provide any benefit in plant growth? Does a particular soil favor a particular variety of plant. ?

EXPERIMENT-Take 3 different type of soils available near you. Grow 3 seeds of the same plant. Keep all other conditions same. Do all plants grow equally?

HYPOTHESIS- Seed grows properly in nutrient rich soil. Seeds may not grow because of the pH of the soil may be too acidic or basic for the seed.
