Number of indoor plants on the second floor. O 11 office - 10 flowers O 10 office - 1 flower O 12 office - no flowers O 9 office - 50 flowers O 8 office - 92 flowers O 7 office - 7 flowers O Recreation - 9 flowers O Laboratory - 12 flowers O Teacher's room - 8 flowers.

From the graph we built, it can be seen that on the second floor of the school the largest number of flowers in room 8, and there are no flowers in room 12 - which is not entirely correct, since each school room should have at least 2-4 indoor plants, the benefits of which we will say below.

Chlorophytum. O An unpretentious herbaceous plant with succulent tuberous roots and a short stem, from which linear or broadly lanceolate soft leaves extend in an arcuate manner. The leaves are green, but variegated forms are more commonly cultivated. O The most famous is chlorophytum crested, or tufted, which is sometimes called "viviparous corolla". The linear leaves of Chlorophytum fasciculata are collected in a rosette, long peduncles grow from their axils, bearing several flowers on top, after flowering in the axils of underdeveloped leaves located on peduncles, numerous children appear - young plants consisting of a bunch of leaves and roots.

O Chlorophytum is unpretentious, grows well in a bright room, although it also tolerates some shading (it is undesirable only for variegated forms, which lose their decorative effect with a lack of light). The soil for chlorophytum should be loose, make up a mixture of sod, humus, peat soil and sand. The plant responds well to fertilization. Water abundantly in summer, moderately in winter. Transplanted in spring. The dishes should be free, as with their thick roots, chlorophytum can break a cramped pot. Chlorophytum reproduces by children.

Importance of plants in school. O Plants decorate the school premises. O Plants have a beneficial effect on the nervous system, improve mood and improve health. O Plants increase indoor air humidity, which is especially important in winter; they protect against dust and microscopic harmful particles, ionize the air and enrich it with oxygen.

Conclusions: O Our group examined the number of flower pots on the 2nd floor of the school; O Based on this, we built a graph of the number of flower pots in different rooms; O They also gave a description of one type of houseplant, in our case it was chlorophytum; A We have achieved our goals and completed our research work.
