From the beginning of the 20th century, the microscope allowed research in cell structure, the general functional unit of living beings. Advances in cytology gradua

The Two Phases of Sporophyte Developmentwo phases: first, a phase of ., similar to that found in animals, during which the original zygote segments and proliferation builds the first organs of the young sporophyte. Incapable of living alone during this period, the embryonic sporophyte is a parasite of the organism on which it was born; it is said to have an . life.

The Differentiation of Plant Cellsous cells or striated muscle cells. So, they can conceive that plant cells sufficiently rich in living material can dedifferentiate and produce young cells again, whereas a real dedifferentiation does not commonly exist in animals.

Parenchymast when they are most active. Due to this distribution, parenchyma have been compared to the . of animals. This comparison is quite inadequate if we consider that parenchyma along with meristems are the main sites of the . of the plant. Therefore, they are the first to be discussed.

Phloemfferentiated for this function or “conducting tissues” are divided into two types: . and . or .. The terms phloem and xylem, introduced by . (1858), appear to be the most convenient and their generalized use is justified.

Xylem (Vascular Tissue)o phloem which conducts the products elaborated in those organs where the syntheses occur and in those where organic substances are stored. However, this specialization of conduction does not exclude the fact that the xylem may also store elaborated organic substances such as starch.
