What gas is needed for germination?
oxygen
Who gases are given out during photosynthesis?
Carbon Dioxide gas is taken in during photosynthesis and oxygen gas is given out whereas during respiration in plants oxygen gas is taken in and carbon dioxide gas is given out.
What are the basic factors in seed germination?
The three factors necessary for germination of a seed are: (1).Water: Seed obtains water from its environment, i.e from the soil, in natural conditions. The water is absorbed all over the surface but mainly through the micropyle. Two main uses of water are: (i) The seed swells and consequently the seed coat ruptures allowing the elongating the radicle to come out and form the root system. (ii). water is necessary for chemical reaction and for the enzymes to act on the food stored in the cotyledons or the endosperm so that it is converted into diffusable form dissolved and utilized by the growing embroyo. (2).Suitable temperature: Both very low and high temperatures are unsuitable for germination.A very low temperature inhibits the growth of the embroyo and a very high temperature destroys its tissues.A moderately warm temperature(25 degrees to 35 degrees centigrade) is usually favourable for germination and it is also called optimium temperature.Seeds of tropical plants need a higher temperature than those of the temperate regions. (3).Oxygen: During germination there is rapid cell division and cell growth for which energy is required.This energy is available only by respiration(for oxidation of food) and hence the need for oxygen(or air).
What gases are not used during respiration?
Cabon dioxideOnly Oxygen gas is needed. No other gas is required
What gas do plant use during photosynthesis?
Oxygen and water. A+. Tony B. Oxygen is given off as a byproduct by plants during photosynthesis. Plants does very well gas during photosynthesis, you might beable to learn this during science class.
What gas is needed for germination?
oxygen
Why is it important to have gas springs on your motocross?
It is important to have gas springs on your motocross to regulate the amount of gas needed during operation. Without the gas springs, the machine would not operate.
Who gases are given out during photosynthesis?
Carbon Dioxide gas is taken in during photosynthesis and oxygen gas is given out whereas during respiration in plants oxygen gas is taken in and carbon dioxide gas is given out.
What gas given off by plants to the during photosynthetic process is needed by living things?
during photosynthesis plants take in carbon dioxide and give out oxygen

What gas that suppots burning rusting and germination of seeds?
Oxygen. It must be present along with fuel and heat for combustion or burning. It combines with elemental iron (Fe) to form iron oxide or rust. Oxygen and moisture are necessary for the germination of seeds.
What is gas needed for?
Oxygen is the gas that is required for respiration.
What gases are not used during respiration?
Cabon dioxideOnly Oxygen gas is needed. No other gas is required
What would happen if you didn't pass gas when you needed to?
If you didn't pass gas when you needed to you would get a pain in your stomach.
What factors affect seed?
Factors affecting seed germinationSeed germination depends on both internal and external conditions. The most important external factors includetemperature, water, oxygenand sometimes light or darkness.[2] Various plants require different variables for successful seed germination, often this depends on the individual seed variety and is closely linked to the ecological conditions of a plant'snatural habitat. For some seeds, their future germination response is affected by environmental conditions during seed formation; most often these responses are types of seed dormancy.Water - is required for germination. Mature seeds are often extremely dry and need to take in significant amounts of water, relative to the dry weight of the seed, before cellularmetabolism and growth can resume. Most seeds need enough water to moisten the seeds but not enough to soak them. The uptake of water by seeds is called imbibition, which leads to the swelling and the breaking of the seed coat. When seeds are formed, most plants store a food reserve with the seed, such asstarch, proteins, or oils. This food reserve provides nourishment to the growing embryo. When the seed imbibes water, hydrolytic enzymes are activated which break down these stored food resources into metabolically useful chemicals.[2] After the seedling emerges from the seed coat and starts growing roots and leaves, the seedling's food reserves are typically exhausted; at this point photosynthesis provides the energy needed for continued growth and the seedling now requires a continuous supply of water, nutrients, and light.Oxygen - is required by the germinating seed formetabolism.[3] Oxygen is used in aerobic respiration, the main source of the seedling's energy until it grows leaves.[2] Oxygen is an atmospheric gas that is found in soil pore spaces; if a seed is buried too deeply within the soil or the soil is waterlogged, the seed can be oxygen starved. Some seeds have impermeable seed coats that prevent oxygen from entering the seed, causing a type of physical dormancy which is broken when the seed coat is worn away enough to allow gas exchange and water uptake from the environment.Temperature - affects cellular metabolic and growth rates. Seeds from different species and even seeds from the same plant germinate over a wide range of temperatures. Seeds often have a temperature range within which they will germinate, and they will not do so above or below this range. Many seeds germinate at temperatures slightly above room-temperature 60-75 F (16-24 C), while others germinate just above freezing and others germinate only in response to alternations in temperature between warm and cool. Some seeds germinate when the soil is cool 28-40 F (-2 - 4 C), and some when the soil is warm 76-90 F (24-32 C). Some seeds require exposure to cold temperatures (vernalization) to break dormancy. Seeds in a dormant state will not germinate even if conditions are favorable. Seeds that are dependent on temperature to end dormancy have a type of physiological dormancy. For example, seeds requiring the cold of winter are inhibited from germinating until they take in water in the fall and experience cooler temperatures. Four degrees Celsius is cool enough to end dormancy for most cool dormant seeds, but some groups, especially within the family Ranunculaceae and others, need conditions cooler than -5 C. Some seeds will only germinate after hot temperatures during a forest fire which cracks their seed coats; this is a type of physical dormancy.Most common annual vegetables have optimal germination temperatures between 75-90 F (24-32 C), though many species (e.g. radishes or spinach) can germinate at significantly lower temperatures, as low as 40 F (4 C), thus allowing them to be grown from seed in cooler climates. Suboptimal temperatures lead to lower success rates and longer germination periods.Light or darkness - can be an environmental trigger for germination and is a type of physiological dormancy. Most seeds are not affected by light or darkness, but many seeds, including species found in forest settings, will not germinate until an opening in the canopy allows sufficient light for growth of the seedling.[2]Scarification mimics natural processes that weaken the seed coat before germination. In nature, some seeds require particular conditions to germinate, such as the heat of a fire (e.g., many Australian native plants), or soaking in a body of water for a long period of time. Others need to be passed through an animal'sdigestive tract to weaken the seed coat enough to allow the seedling to emerge
