Unusual flowers

Makaricheva Yu.V.

NOU "Noginsk Gymnasium"

Amorphophallus titanica- the largest tropical flower, and very foul-smelling.

This flower has one of the largest inflorescences in the world - it can reach a height of 2.5 m and a width of 1.5 m. Flowering lasts only 2 days. Initially, amorphophallus grew in Indonesia, on the island of Sumatra. Subsequently, this flower was exterminated by foreigners. Currently, this flower is very rare and can be seen mainly in botanical gardens around the world.


Wolfia

Wolfia is the smallest flowering plant on Earth. Their size ranges from 0.5 to 0.8 mm. These small flowers live on the surface of the water. It was named after the German botanist and entomologist Johan F. Wolf.


Psychotria sublime

People call him “hot lips” for its bright red inflorescences. Psychotria is a tropical flower that loves moisture and warmth. Therefore, its homeland is the tropical forests of Central and South America.


Orchid Kalania

African Hydnora

Passionflower

Passionflower, or Passion flower- genus of the Passionflower family. There are about 500 species. The flower reaches 10 cm in diameter. It grows mainly in Latin America.


Sundew

Sundew is a carnivorous plant. Thanks to the mucus droplets they secrete, they catch insects on which they feed. They grow in swamps, sandstones and mountains.


Nepenthes Attenborough

An unusual flower was discovered in 2000, on the island. Palawan by three scientists Stuart McPherson, botanist Alistair Robinson and Filipino scientist Volker Heinrich, who went here on an expedition to collect this flower. They first heard about it from missionaries who had visited the island earlier. On Mount Victoria, scientists discovered huge “jugs” of these flowers. These turned out to be predator flowers that “feed” on rodents. How these flowers were able to survive to this day is unknown. They are now being studied in MacPherson's laboratory.


Mimosa púdica is a plant that is shy

Mimosa púdica is a very sensitive plant. The fact is that if you touch a mimosa, or it is caught by a gust of wind, the mimosa immediately “pretends” to be dead, all the leaves fall to the ground, and the plant seems to wither. After just a few minutes, the mimosa comes to its senses, only to “wither” again as soon as someone or something touches it. Found in South and Central America.

Common arum - a plant up to 90 cm tall, leaves reach 20 cm in length. Leaf petioles and fleshy stems - with brown spots, which makes them look like snake skin. An inflorescence appears at the top of each stem in early summer. A spathe with a wavy edge reaches a length of 45 cm. It is pale green on the outside, purple-crimson on the inside. A dark purple spadix is ​​the same length as the spathe.

The largest inflorescence in the world, not a flower, Amorphophallus belongs to the lily family. Its flowers are huge leaves dissected in the middle, from which a large cob emerges. The aroma of amorphophallus is usually compared to the smell of rotten eggs, spoiled fish or meat, but it attracts insects that pollinate the Amorphophallus plant was discovered by a Florentine scientist in 1878 in Sumatra. The plant lives for about 40 years and during this time it blooms only a couple of times. Reaches a height of 2.6 m and above; It is a short-lived plant ( most years is in a state of rest). It forms a tuber in the soil; its tuber diameter is half a meter or more; tuber weight – up to 23 kg. summary of presentations

Class: 6th grade Lesson topic: “Flower” The purpose of the lesson is to study the structure and functions of a flower. Lesson objectives - Educational: to develop students’ knowledge about the flower as an organ of seed reproduction angiosperms; study the structural features and diversity of flowers; form the concepts of “both - and unisexual flowers”, “mono- and dioecious plants”. Developmental: develop practical skills in recognizing flowers of various plants; work with a textbook; generalize the knowledge gained, draw independent conclusions. Educational: to cultivate love and respect for nature and flowering plants; develop curiosity and the desire for knowledge. Formed UUD: cognitive - establishing cause-and-effect relationships, generalization, putting forward hypotheses, working with text; regulatory - goal setting, adequate self-assessment of performed actions, self-regulation of emotional state; communicative - formulating one’s own opinion, the ability to listen to the opinions of others, organizing group activities in cooperation, mutual control and mutual assistance.

Equipment: PC, projector, presentations, textbooks, flower models: cherry, potato, pea, blooming houseplants, table “Structure of a flower”, terms on the topic, herbarium material, drawn parts of a flower, test tasks. Lesson type: learning new material. Teaching methods: conversation, problem-search, explanatory-illustrative, research. Lesson type: lesson on learning new knowledge. Educational and methodological literature: teaching materials of the line of V.V. Pasechnik.

A flower is an organ of seed reproduction. A flower consists of a receptacle, perianth, pistil and stamens. The perianth can be simple or double The petals of a flower form a corolla, and the sepals form a calyx Flowers are unisexual (contain both pistils and stamens) and dioecious (contain only stamens or only pistils) Plants on which both staminate and pistillate flowers develop are called monoecious Plants on which they bloom only pistillate or only staminate flowers, called dioecious 2 Conclusions:

Homework. Study paragraph 28, learn the terms, make a model of a flower (bisexual or unisexual).

Reflection. Have you achieved your lesson goal? In what degree? What did you learn new in the lesson? What surprised you?

Slide 3

We all love flowers, they decorate our lives, make it more colorful and bright. Every day hundreds of thousands of flowers are bought and given around the world. And all these flowers were carefully grown by someone to please those who received them.

VIOLET, or VIOLA (VIOLA) family. Violet

Slide 5

Viola is the old Roman name for violet, used by Virgil, Pliny and other authors of that era. Violet or otherwise viola is the favorite flower of various peoples. Pansy - the Russians affectionately call violet. Violets are one of the oldest garden crops. Already about 2,400 years ago, the ancient Greeks and Romans wove violets into wreaths and garlands to decorate rooms during holidays and dinner parties. Annual, biennial and perennial herbaceous plants. The leaves are arranged in a regular order or collected in a basal rosette. The flowers are solitary, the lower petals are larger than the rest, with a spur or sac-like outgrowth at the base, the rest with marigolds, white, blue, yellow, red. The fruit is a capsule. In 1 g there are up to 800 seeds that remain viable for up to 2 years. The genus includes more than 450 species distributed throughout the globe.

Slide 6

ANEMONE, or ANEMONE fam. Ranunculaceae

Slide 7

The name comes from the Greek word "anemos" - wind. Flower petals of most species easily fall off in the wind. The genus includes about 150 species of herbaceous perennial plants, distributed in the temperate zone of the Northern Hemisphere (several species grow in North Africa).
