There are plants in which flowers develop one at a time at the ends of the shoots or in the axils. These are single flowers. And other plants have flowers collected in inflorescences.

Inflorescence- this is a shoot of a plant, flower bearer and bearing no leaves.

Inflorescences there are simple And complex. Inflorescences are usually collected small flowers, which makes them highly visible to pollinating insects.

Cabbage, lily of the valley, bird cherry have inflorescence brush. In such an inflorescence, individual flowers are located one after another on clearly visible pedicels extending from a long common axis.

Simple ear form flowers without pedicels (that is, sessile), located on the common axis of the inflorescence, like those of plantain. Inflorescences of wheat, rye, barley are called complex ear. In this inflorescence, several spikelets sit on a common axis, each of which is formed by several flowers (in rye, for example, two).

cob differs from the spike by the thick, usually fleshy axis of the inflorescence.

Simple umbrella- an inflorescence in which the pedicels extend from the top of the inflorescence axis. Primrose has such an inflorescence.

The inflorescence is a simple umbrella. Example -

Simple inflorescences can be grouped into complex inflorescences. Carrots and parsley have umbrella inflorescences, consisting of several simple umbrellas. This inflorescence is called complex umbrella.

Objectives: Develop knowledge about the diversity of flowers; reveal the content of the concept of “inflorescence”, introduce students to the most common types of inflorescences and explain their biological role.

Equipment: Tulip and narcissus flowers, tables “Simple and complex inflorescences”, herbarium specimens of plants.

The inclusion of game moments and elements of entertaining biology in educational activities makes the lesson effective and also contributes to the development of cognitive interest. At the same time, lessons are freed from the monotony of monotony and acquire an emotional overtones.

10. Flowers collected in the inflorescence of the basket, as a rule: a) small, sessile; their calyx is modified into a tuft of hairs or is absent; b) small, with very short pedicels; their calyx consists of small sepals; c) small, sessile, without perianth.

11.A complex shield is an inflorescence formed by: a) only simple shields; b) only simple umbrellas; c) not only with simple shields.

When summing up the lesson, the teacher talks about the biological role of inflorescences.

Small flowers are collected in groups - this promotes their pollination, and, therefore, the formation of fruits and seeds.
