The cell is the structural and functional unit of all living beings. The cell was discovered by the British scientist Robert Hooke in 1665. He was the first to see tiny blocks in slices of cork through a microscope. He gave them the name "cells" which means "small rooms" in Latin.

Later, it was discovered that all plants and animals consist of cells. In the 1830s German researchers, Matthias Schleiden and Theodor Schwann, came to the conclusion that plant cells and animal cells have the same structure and that the cell is the basic unit of any living tissue. Their discovery led to the creation of The Cell Theory which states that:

• The cell is the unit of structure, physiology, and organization in living things.

• All cells are basically the same in structure, chemical composition and vital functions.

• All new cells come from pre-existing cells by division.

Every living being has from one to trillions of cells. Tiny amoebas are one-celled organisms and a human body contains trillions of cells. Cells form different tissues and organs and therefore have different purposes. For example, blood cells and muscle cells don't look like each other very much (see picture 1) because their functions are different. However, according to The Cell Theory their structures are quite similar and they consist of the same basic elements.

• The structure of plant cells differs a lot from the structure of animal cells.

• If an organism has only one cell, it can still be defined as a living being.

• The Cell Theory states that epithelial (skin) cells are absolutely identical to osteocyte (bone) cells.

4 Работайте в парах. Прочитайте информацию и отметьте утверждения ниже как верные или ложные. Прокомментируйте свое решение.

Ответ:

1. The structure of plant cells differs a lot from the structure of animal cells. - False

Перевод: Строение растительных клеток сильно отличается от строения клеток животных. - Ложь

Comment: The text states that "plant cells and animal cells have the same structure" and that "All cells are basically the same in structure".

Комментарий: Текст утверждает, что "клетки растений и клетки животных имеют одинаковое строение" и что "все клетки в основном одинаковы по строению".

2. If an organism has only one cell, it can still be defined as a living being. - True

Перевод: Если организм состоит только из одной клетки, его все равно можно определить как живое существо. - Истина

Comment: The text mentions that "Tiny amoebas are one-celled organisms", confirming that single-celled organisms are living beings.

Комментарий: В тексте упоминается, что "крошечные амебы являются одноклеточными организмами", подтверждая, что одноклеточные организмы являются живыми существами.

3. The Cell Theory states that epithelial (skin) cells are absolutely identical to osteocyte (bone) cells. - False

Перевод: Клеточная теория утверждает, что эпителиальные (кожные) клетки абсолютно идентичны остеоцитам (костным клеткам). - Ложь

Comment: The text states that "All cells are basically the same in structure" and that "their structures are quite similar", not "absolutely identical". It also notes that different cells have different purposes and don't look like each other very much.

Комментарий: Текст утверждает, что "все клетки в основном одинаковы по строению" и что "их структуры довольно схожи", а не "абсолютно идентичны". Он также отмечает, что разные клетки имеют разное назначение и не очень похожи друг на друга.
