The seeds contain a plant embryo and stored food. The cells of the embryo begin to grow when the external conditions are favourable and water is available. Enzymes break down the stored food and respiration produces ATP. Describe an experiment, using growing mung bean seeds, to investigate the effect of temperature on the rate of respiration. (5)

The seed germination is the process in which embryo found in the seed develops into plumule and radicle. Seeds absorb water and which swells the inactive tissues and start the cell division. The ...

Introduction. You might already know that if you plant a seed it will grow into a plant. But did you know that inside of every seed is a baby plant? The inside of a plant seed has three main parts: the embryo is the baby plant, the endosperm is food for the baby plant, and the cotyledon(s), which look like leaves and contain the endosperm. All of the parts of the …

Digestive fluids may alter the seed coat or endocarp, thus affecting germination patterns. Digestive enzymes and stomach acids serve to break foods down (Sturkie 1976), including seeds. Seed treatment may also be affected by symbiotic bacteria and protozoa, which can digest structural polymers of the cell wall during fermentation …

The evolution of root systems about 430 million years ago greatly changed how plants interacted with rocks. Roots can effectively break up rocks and promote …

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.

Methods. We dug up the 16th bottle in April 2021 and attempted to germinate the 141-year-old seeds it contained. We grew germinants to maturity and identified these to species by vegetative and ...

Seeds & Germination Background Information. Definitions. A seed is a small embryonic plant enclosed in a covering called the seed coat, usually with some stored food. It is the product of the ripened ovule of gymnosperm and angiosperm plants which occurs after fertilization and some growth within the mother plant.

Leaching in cement-based materials and dissolution in rocks are important problems in civil engineering. In the past century, concrete damage caused by leaching have occurred worldwide. And, rock dissolution is usually the main cause of karst rock erosions. This paper provides a review of the causes, influencing factors, and effects on …

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 ...
