4.6.4: Germination

Germination in Monocots. As the seed germinates, the radicle emerges and forms the first root. In epigeous monocots (such as onion), the single cotyledon will bend, forming a hook and emerge before the coleoptile (Figure 4.6.4.5 4.6.4. 5 ). In hypogeous monocots (such as corn), the cotyledon remains belowground, and the coleoptile emerges first.

1. Introduction. Seeds of many wild species are collected and placed in dry storage because they are needed for habitat restoration projects [].At some point in time, the stored seeds will be sown in the field in an attempt to establish new populations [] or in nurseries to generate plants for out-planting to sites that need to be restored [3,4,5].

Make Apple Seeds Dance – Experiment Exchange

Instructions. Fill the your clear cup or glass about 2/3 full with vinegar. Drop in the apple seeds; they will sink to the bottom. Add about 1 teaspoon of baking soda per cup of vinegar used and stir. (Adding more baking soda will create a big volcanic eruption!

An Easy Kids Science Experiment

Instructions. The day before the experiment, soak 1 seed per child in water overnight. This will soften the seed coat and make it easier to dissect the seed. Talk to your kids about seeds. Show them …

Experiment: Those Swell Seeds | Answers in Genesis

The process of seeds absorbing water is called imbibition. During imbibition, a seed can swell to several times its original size. This swelling can cause tremendous pressure—often over 1,000 pounds per square inch (6900 kPa). Swelling seeds can break rocks and concrete or, in the case of the Cali, rupture a steel cargo ship. This swelling ...

Mendel's Experiments: The Study of Pea Plants & Inheritance

All of the plants in the F1 generation had round seeds.This seemed to suggest that the wrinkled trait had been obliterated by the round trait. However, he also found that, while about three-fourths of the plants in the F2 generation has round seeds, about one-fourth of these plants had wrinkled seeds.Clearly, the wrinkled trait had …

Growing Beans in the Classroom

Directions. Fill the container about halfway with paper towels. Place several beans on the outside of the paper towels in the container so you can watch them grow. Spray the paper towels with water to dampen them. Place the container near a window or on a window ledge. Observe and watch the beans grow over the following days and weeks!

4.3: Weathering

Weathering is the process that changes solid rock into sediments. Sediments were described in the Rocks chapter. With weathering, rock is disintegrated. It breaks into pieces. Once these sediments are separated from the rocks, erosion is the process that moves the sediments. Erosion is the next chapter's topic.
