In the process of photosynthesis, not only organic matter is formed, but also free oxygen. Its release into the environment can be seen in the following experiment. Take
To answer the question of what substances organic substances are formed from, we will carry out the following experiment. Place two plants (pelargonium, begonia) in a dark cabinet.
Some plants, such as pelargonium (edged geranium) or chlorophytum, have variegated leaves. Their white areas are formed by cells without chloroplasts. Cut off one leaf of chlorophytum and
You can make sure that starch is formed in the leaves in the light by experiment. Plant in the dark Place the houseplant (pelargonium, begonia) in a dark
Photosynthesis mainly occurs in green leaves. Due to the flat shape of the leaf blade, the leaf has a large contact surface with air and sunlight. Photosynthesis takes
Plants are unique organisms! They are capable of forming organic matter, glucose, from carbon dioxide and water in the light. This amazing process is called photosynthesis. The ability
How plants absorb minerals Algae, as well as some aquatic plants, assimilate minerals throughout the body. Higher plants absorb them from the soil in the form of solutions
Water and mineral salts enter the plant mainly through the roots from the soil. This process is called mineral nutrition. In this process, the root hairs in the
Plants contain organic matter (proteins, fats, carbohydrates), minerals and water. Water Water is essential for all vital processes in the plant organism. Therefore, cells in which vital processes
The seed is a special multicellular structure of a complex structure that serves for reproduction and dispersal of seed plants, usually developing after fertilization from the ovule (modified
