What reading level is A Course of Practical Instruction in Botany volume 2 book?
To quickly assess the difficulty of the text, read a short excerpt:
According to circumstances, the following reproductive organs may or may riot be found : 1. Swarm-spores, each of which is formed from the contents of a single cell of the thallus, by contrac- tion, and escape through a hole in the cell-wall into the water : the swarm-spores are spherical primordial cells ; they move for a time by means of a pair of cilia.
2. Antheridia, which are formed by division of cells of the disk into four : the contents of these escape as ciliated antherozoids. In other... species they may be formed from terminal cells of the filaments (G. Pulmnata).
3. Oogonia, flask-shaped cells, with long tubular necks : each oogonium contains one ovum.
4. The fructification, which results partly from the maturation of the oogonium after fertilisation (oospore), partly from its investment by filaments which grow from surrounding cells, forming a sheath one layer of cells in thickness, and of a brown colour when ripe. In this state the winter is passed.
5. In specimens observed in spring the general out- line of the thallus will be seen as before, but the cells, excepting those of the fructification, have lost their COLEOCH^TE.
