There are currently three hundred and ninety thousand, nine hundred varieties of plants on our planet. However, plant species can be divided into twelve categories:

Cruciferous. This category includes organisms that are pollinated by insects. It includes approximately three thousand organisms. Virtually all species of grasses are included in this category. Among the most prominent representatives are white cabbage.

Rosaceae. Counts about three thousand representatives. A distinguishing feature is the leaflets. Common plants, examples: plums, wild apple, rose.

Solanaceae. Fruits with a capsule or berry. Contains more than two thousand species. Potato and tomato, for example.

Cereals. One of the most common. Includes more than ten thousand species. Examples: wheat, bamboo, cane.

Gourds. A flowering plant with just over six hundred species. Examples: pumpkin, cucumber, watermelon.

Onions. Perennial herbs. Onions are loved throughout the world, with the exception of Australia. Prominent representatives: onions, ramson, leeks.

Pines. Leaves in the shape of spirals. Trees are monoecious. Examples: spruce, cedar fir.

Cypress. Interestingly, female cones are larger than male cones. Widespread throughout most of the globe. Examples: cypress, juniper, sequoia.

Complexiflowered. Counts twenty-seven thousand species. Broad in application: from ornamental purposes to the production of goods. Examples: sunflower, apothecary chamomile, ragweed.

Lilacs. Pollination by insects and wind. There are more than four thousand representatives of the species. Examples: lily, cankerwort, clintonia.

Aquaria. For the most part originally grew in the tropics. Now used in the decoration of aquariums. Examples: anubias, ammania gracilis, barclaya longifolia.

Carnivores. Perhaps the most interesting category. They feed on insects and small animals, not sunlight. Examples: venus flycatcher, cephalot, roridula.
