knowledge The questions assume that the student has an understanding of photosynthesis. Advance preparation and materials Plants. Dig up small plants (e.g. garden weeds) 10-20 cm tall and wash as much soil as possible off their roots. Select those whose root system can be fitted into a 5 or 10 cm3 syringe barrel; remove leaves as necessary from the bottom 2 cm of the stem and keep the plants in the shade in a jar of water until needed. Syringe barrel. The narrow pattern of a 10 cm3 syringe
Premium Photosynthesis Root Plant
basic organs of a vascular plant are the stems‚ leaves‚ and roots. The stems consist of nodes‚ where leaves attach‚ and internodes between the nodes. The stem is responsible for elongation of the plant and acts as a central axis for other organs to attach to. The roots help to anchor the plant as well as absorb water and nutrients from the soil. In addition‚ roots often form mycorrhizae with fungi‚ providing further advantage. Some roots are specially designed to store nutrients for later use of

captured from the air by species of bacteria that lie in the water‚ soil‚ or grow on the roots of some plants. These bacteria convert the nitrogen into a form usable by plants. The process of bacteria converting nitrogen into a form usable by plants is called nitrogen fixation. Rhizobium is a species of bacteria that performs nitrogen fixation. Its presence can be proven by the appearance of nodules or bumps on the root of the plant. It helps the plant by giving it usable nitrogen and in return the bacteria
Premium Plant Legume Plant morphology
A tissue can be simple or complex depending upon whether it is composed of one or more than one type of cell. Tissues are further arranged or combined into organs that carry out life functions of the organism. Plant organs include the leaf‚ stem‚ root‚ and reproductive structures. The first three are sometimes called the vegetative organs and are the subject of exploration in this chapter. Reproductive organs will be covered in Chapter 5. The relationships of the organs within a plant body to

xylem in the roots is transported upwards through the stem to the leaves‚ which is a process also known as transpiration. The phloem transport sugars to the whole of the plant. Sugars are made in leaves of the plant during photosynthesis. Sugars that are transported to other cells can be used as food to provide energy for the cell. The process of breaking down sugars to create energy is called respiration. Plants that live on land need to obtain their water and minerals through root systems. There
