About Plants Part 3

At least some factory cells contain photosynthetic organelles (plastids plastids) which enable them to make food for themselves. With sun, water, and carbon dioxide, the plastids make sugars, the basal crumbs bore by the factory. Free oxygen (O2 O2) is produced as a by- product of photosynthesis. (7 7)

Thereafter, in the cell cytoplasm, the sugars may be turned into amino acids for proteins, nucleotides for DNA and RNA, and carbohydrates alike as brio. This process needs certain minerals nitrogen, potassium, phosphorus, iron and magnesium.

The roots of shops perform two main functions. First, they anchor the shop to the ground. Second, they absorb water and polychromatic nutrients dissolved in water from the soil. Shops use the water to make food. The water also provides the shop with support. Mills that involve water go really limp and their stems can not support their leaves. Mills which specialise in desert areas are called xerophytes or phreatophytes, depending on the type of root growth.

Water is transported from the roots to the rest of the mill through special vessels in the mill. When the water reaches the leaves, some of it evaporates into the air. Multifold mills need the help of fungi to make their roots work duly. This mill-fungi symbiosis is called mycorrhiza. Rhizobia bacteria in root lumps help some mills get nitrogen.
