leaves and to conduct materials from one part of the plant to another. 8. The
primary function of the petals of the flower is undoubtedly to attract insects and
birds to plants for pollination purposes. 9. The main purpose of this book is to
consider the role of photosynthesis in the life of plants. 10. At this stage
different organs begin to take form. 11. One of the main functions of the nucleus
is to regulate normal vital activity of the cell. 12. We have to read much to
become good specialists.

1. It is difficult to give a simple definition of life. 2. After the division it is
impossible to define which of the cells obtained is maternal and which is the
daughter one. 3. It is worth while to pause for a moment to see what happens
inside an organism when it grows.
D
1. The flora of lichens and mosses, the first of the individual groups to be dealt
with, is large and diverse. 2. The size to be attained by a newly-born cell is that
of the parent cell. 3. The new materials to be added into the cell are distributed
in the living protoplasm and become a part of its finely organized structure. 4.
They have an excellent laboratory to work in. 5. Each group of cells in many
celled bodies has definite functions to be performed. 6. All the functions to be
performed by an organism should be correlated and contribute to the activities of
the whole. 7. This is one of the important items to be insisted upon. 8. The only
tissue to be affected by the lack of glucose is the central nervous system.
Ex. 8. Analyze the sentences below and put the Absolute Participle
constructions in brackets.
1. There being no normal conditions for the development of the cell, it stops its
existence. 2. All living matter consists of protoplasm, lifeless matter having no
protoplasm. 3. Cells will not carry on actively their metabolic processes, with
nucleus having been removed. 4. The term tissue includes living cells and
structures produced by them, the cell wall, the hard material of bone and the
fibers of tendons being examples of it. 5. In the early stages of an embryo the
cells are much alike, their differentiation taking place much later.

Ex. 9. Read the text and tell what definitions of organ and tissue it
gives, what types of tissues are mentioned in it.

In the early stages of an embryo the cells are usually much alike. But later
they start specializing to carry on a particular function. This is the stage when
