Seed of various plants can be broadly divided into two groups. Those which germinate in autumn and winter, and those which germinate in spring and summer. Seed which normally germinates in spring and summer requires relatively warm germination temperatures (22 - 24 degrees Centigrade), while winter germinating seed requires temperatures between 18 and 20 degrees Centigrade. A number of seed types also have something called dormancy, this prevents seed which is dispersed at the end of the growing season from germinating immediately. For example, a plant flowers and produces seed in Summer. The seed is dispersed and drops to the ground. The seed may require a period of extreme cold or chilling before it will germinate. This prevents the seed from germinating and the the young plant being killed by low winter temperatures. The reverse is true of Winter seed.

What growth temperature is the temperature at which an organism exhibits the highest growth rate?
optimal
What affects the growth of bacteria?
The rate of bacterial growth may be affected by environmental factors both physical and biochemical. The physical factors include temperature, light, oxygen concentration, moisture, pH, hydrostatic pressure, osmotic pressure and radiation. The biochemical factors or nutritional factors include availability of carbon, nitrogen, sulfur, phosphorus, trace elements and in some cases, vitamins.
Classmate suggests that temperature might affect the rate of mitosis in plant cells Design an experiment to test this hypothesis?
Temperature affects the rate of cell progress that is the mitotic rate to quite some extent. With the increase in temperature(3-25 degrees C) the mitotic cycle rate increases linearly.
In what ways could you adjust incubation temperature to grow an orgainsm at less than its optimal growth rate?
lower it below or raise it above the the optimum temperature
What do all plants need?
they need sunlight, water, soil, a suitable temperature, and protection. Using music will increase the rate of the plants growth
What is an example of an idependent variable?
Temperature is typically an independent variable used a lot of experiments. Say, for example, you are trying to see how temperature affects the growth rate of bacteria. You would know the values of temperature being used in the experiment because you are either increasing the temperature or decreasing it. The growth rate of the bacteria would be dependent on the temperature because increases and decreases in temperature could affect growth rate. In essence, the independent variable is typically the component you control in an experiment.

What affects both the rate of solution and the solubility of a solid in a liquid?
Temperature affects both the rate of solution and the solubility of a solid in a liquid
What affects the rate of diffusions?
Temperature, Concentration and size of molecules :)
which of the following affects the rate of constant of a reaction?
The temperature of the system
Which factor affects both the solubility of a substance and the rate at which it dissolves?
temperature
what tools show how air temperature affects the rate of evaporation of water?
thermometer
What was the temperature and cloud cover on December in Kansas city?
Cloud cover does not have a temperature. It affects the rate of heating or cooling.
How does temperature affect the growth rate of salmon?
Temperature affects the growth of salmon because.... if you give it sunlight and plenty of water it will grow. If it is cold then it probably will not grow at all. It is like plants and trees, salmon needs sunlight and if you water well enough then it will grow as you planned!!!!!!!!!!! thanx for asking this question...... i was happy enough to answer it for you.
How does temperature affects the rate of industrial reaction?
It depends. A higher temperature will speed up an endothermic reaction, but slow down an exothermic reaction.
