plant firmly in the soil. 5. What happens in the process of photosynthesis? For the process of the photosynthesis is sunlight necessary. Water from the soil and carbon dioxide from the air are converted into sugars and after carbohydrates. Durning the process oxygen is formed and relased into the air. 6. Name the reproductive organs of a flower. How they function? reproductive organs of the flower are the stamens and the carpel. The stamens produce men sex cells and the carpel produces the female sex cells. 7. Seed function: to develope into to a new plant, to consist of embryo and foodstore. 8. Name the conditions for germination. The conditions that is needed for germination are: * the right temperature in the soil * the right amount of moisture * the seeds must be alive *the right amount of soil aire, oxygen. Sufficent oxygen. 9. Describe the first stage of germination.

Alustatakse tervisebakterite ehk probiootikumide teaduslikke uuringuid. Ija Metsnikov tõestab, et Bulgarian bacillus võtab osa seedimisprotsessist ja tugevdab immuunsüsteemi.

later in the season, and normally unbranched. Sunflower leaves are phototropic and will follow the sun's rays with a lag of 120 behind the sun's azimuth. This property has been shown to increase light interception and possibly photosynthesis. The sunflower head is not a single flower (as the name implies) but is made up of 1,000 to 2,000 individual flowers joined at a common receptacle. The flowers around the circumference are ligulate ray flowers without stamens or pistils; the remaining flowers are perfect flowers (with stamens and pistils). Anthesis (pollen shedding) begins at the periphery and proceeds to the center of the head. Since many sunflower varieties have a degree of self-incompatibility, pollen movement between plants by insects is important, and bee colonies have generally increased yields. In temperate regions, sunflower requires approximately 11 days from planting to
