Answer 1

•1.All plants have a similar structure. Every plant is made up of parts called organs. Each organ has its own name: root, stem, leaf, flower, fruit with seeds

•2.The main functions of K.: provision of mineral and water nutrition (absorption and transport of water and mineral substances); fixing the plant in the soil; accumulation of nutrients; synthesis of some substances; vegetative reproduction; symbiosis with bacteria and communication with other soil organisms

•3.Photosynthesis is a complex chemical process of converting the energy of visible light into the energy of chemical bonds of organic substances with the participation of photosynthetic

•4.The stem is the axial part of the shoot, which connects all its components (leaves, buds) into a single whole. The main function of the stem is conducting. It moves water and nutrients dissolved in it from the root to above-ground organs and organic substances from leaves to all organs.

The market today sets strict quality requirements, but our seeds are already being bought in Europe. Ukrainian producers produce and deliver there only high-quality seeds and bear full responsibility for the sold seed material. In general, a lot has been done both by the state and by the participants of this market regarding the entry of domestic seeds into the international market.

•6.Plant reproduction is a set of processes that lead to an increase in the number of individuals of a certain species; asexual, sexual and vegetative reproduction occurs in plants (asexual and sexual reproduction are combined into the concept of generative reproduction). The study of various aspects of reproduction is the subject of reproductive biology[1].
