Understanding Cells: Structure, Functions, and Types

The cell is the smallest unit of a living organism that can carry out vital functions: nutrition, interaction, and reproduction.

Essential Cell Components

All cells possess a plasma membrane, cytoplasm, and DNA.

• Plasma Membrane: This is a very thin and stretchy cover that separates a cell from its environment. Its primary function is to regulate the movement of substances in and out of the cell. It also detects environmental stimuli and allows cells to communicate.
• Cytoplasm: This is the substance contained inside the cell, in which the cell organelles are found. Metabolic processes occur within the cytoplasm.
• Genetic Material (DNA): A complex chemical substance that contains the information needed

Understanding Cells: The Building Blocks of Life

Cells are the fundamental building blocks of all living organisms.

Cell Structure Essentials

A typical cell consists of several key components:

• Plasma membrane: A very thin, stretchy cover composed of lipids, proteins, and carbohydrates that separates the cell from its external environment.
• Cytoplasm: The jelly-like substance filling the cell, enclosing the organelles.
• Genetic material (DNA): A complex chemical substance containing the genetic information necessary to regulate the cell's functions.

Prokaryotic vs. Eukaryotic Cells

Mendelian Principles of Inheritance

Gregor Mendel

• In the 19th century, he studied inheritance: the passing of characteristics from parents to offspring.
• His work was based on the study of the crossing of different varieties of plants.
• The species chosen was the pea (Pisum sativum).

Method

• Characteristic selection
• Obtaining pure-bred individuals for those characteristics

Parental generation (P)

• Crossing two different pure breeds to obtain descendants

First filial generation (F1)

• Crossing F1 individuals and studying their descendants

Second filial generation (F2)

Believing that the revolution was in danger, the radical revolutionaries, or Jacobins, used this support to increase their powers. The Jacobin leader, Maximilien Robespierre, assumed all powers and established a dictatorship.

A special tribunal, the Committee of Public Safety, was established by Georges Danton and Robespierre. They tried people who were suspected of opposing the Republic, even without proof, sentencing them to death by the guillotine, a famous symbol of the French Revolution. Around 50,000 people were executed. Robespierre... Continue reading "French Revolution: Robespierre, Napoleon, and the Rise of Nationalism" »
