Cells VII. Find Russian equivalents for the following word combinations were discovered in 1665 by the English scientist and inventor Robert Hooke. Hooke designed his own compound light microscope to observe structures too small to be seen with the naked eye. Among the first structures he examined was a thin piece of cork (the outer surface of bark from a VII. Find Russian equivalents for the following word combinations tree). Hooke described the cork as being мейд of hundreds of little boxes, giving it the appearance of a honeycomb. He called these little boxes cells. It soon became clear that virtually all living things are мейд of cells, and that these cells have certain features in VII. Find Russian equivalents for the following word combinations common.

The cell theory

The concept that cells are the basic units of life became embodied in a theory called the cell theory, which embraces the following main ideas:

·cells form the building blocks of living organisms

· cells arise only by the division of existing cells

· cells contain inherited information which controls their activities

· the VII. Find Russian equivalents for the following word combinations cell is the functioning unit of life; metabolism (the chemical reactions of life) takes place in cells

· given suitable conditions, cells are capable of independent existence.

A typical animal cell

The structure of a typical animal cell:

· the cell has a cell surface membrane which encloses the cell contents

· the VII. Find Russian equivalents for the following word combinations contents consist of a central ball-shaped nucleussurrounded by material calledcytoplasm

· the nucleus contains a fibrous material called chromatin

· this condenses to form chromosomes during cell division

· chromatin contains DNA, the material which controls the various activities inside the cell

· scattered within the cytoplasm are mitochondria, small rod-like structures. They have been described VII. Find Russian equivalents for the following word combinations as the “power-houses” of the cell because they supply energy.

· smaller dots within the cytoplasm are particles of stored food. Many consist of glycogen, which is a food storage polysaccharide.

A typical plant cell

Like an animal cell, a typical plant cell has a cell surface membrane, cytoplasm, and a VII. Find Russian equivalents for the following word combinations nucleus. However, plant cells differ from animal cells in several ways:

· most plant cells have a large sap-filled cavity called the vacuole.Sap is a watery fluid containing salts and sugars. The vacuole surrounded by a membrane called the tonoplast.

· the cytoplasm contains starch grains, the food storage VII. Find Russian equivalents for the following word combinations products of plants

· many plant cells have chloroplasts in the cytoplasm. These contain the pigments used in photosynthesis. Chlorophyll, which is green, is the main pigment. Chloroplasts occur only in the parts of plants exposed to light – the green parts. They are absent from underground structures such as VII.
