The document discusses photosynthesis and its key roles:
1) Photosynthesis converts solar energy into chemical energy through a process that occurs in chloroplasts in plants, algae, and some bacteria.
2) It produces organic molecules like glucose from carbon dioxide and water, generating oxygen as a byproduct.
3) Nearly all life on Earth relies on photosynthesis, as photoautotrophs feed themselves and also support heterotrophs like animals and humans.

This document provides an overview of the cell cycle and cell division. It discusses the key roles of cell division in reproduction and growth. The cell cycle consists of interphase, where the cell grows and duplicates its DNA, and mitosis, where the cell divides. During interphase, cells pass through G1, S, and G2 phases before entering mitosis. Mitosis is then described in detail, including the formation of the mitotic spindle and movement of chromosomes. Cytokinesis follows to divide the cytoplasm and form two daughter cells. Meiosis is also introduced as a type of cell division that produces gametes.
Endosymbiotic theory (1)
The document discusses endosymbiotic theory and the evolution of eukaryotic cells. It explains that photosynthesizing cyanobacteria produced oxygen that accumulated in the atmosphere over time. Some prokaryotes survived and adapted to oxygen while others took up residence within larger cells as endosymbionts, providing nutrients and shelter. This led to the distinct features of eukaryotic cells through mergers of the smaller prokaryotes and host cells. Later, photosynthetic eukaryotes were engulfed by other eukaryotes in secondary endosymbiosis events, as evidenced in algae with vestigial nuclei. There is overwhelming evidence that mitochondria and chloroplasts evolved in
difference between prokaryotes and eukaryotes
Prokaryotic and eukaryotic cells differ in several key ways. Prokaryotes are smaller, lack membrane-bound organelles, and have circular chromosomes, while eukaryotes are generally larger with organelles like the nucleus and mitochondria and contain linear chromosomes. Another major difference is that prokaryotes reproduce through binary fission while eukaryotes undergo mitosis or meiosis. Examples of prokaryotes include bacteria while eukaryotes include animals, plants, and fungi.
07 ge lecture presentation
This document provides an overview of cell structure and function from a biology textbook. It begins by establishing that cells are the fundamental unit of life and discusses the use of microscopes like light microscopes and electron microscopes to study cells. It then explains that eukaryotic cells have internal membranes that compartmentalize functions, while prokaryotic cells do not. The document outlines some of the major organelles found in plant and animal cells like the nucleus, mitochondria, chloroplasts, and describes how the nucleus contains most of the cell's DNA and the ribosomes are used to produce proteins from that DNA information.
Endosymbiotic theory
1. The Endosymbiotic Theory proposes that organelles like mitochondria and chloroplasts originated from ancient endosymbiotic relationships between bacteria and host cells.
2. Evidence for this includes mitochondria and chloroplasts containing their own DNA, resembling prokaryotic cells. Their protein synthesis mechanisms also resemble bacteria.
3. Molecular sequencing shows mitochondria being most similar to proteobacteria like Rickettsia prowazekii. Chloroplast sequences are similar to cyanobacteria, supporting an endosymbiotic origin.

This document provides an overview of a slide presentation about the endosymbiotic origins of mitochondria and chloroplasts. The presentation aims to teach students that mitochondria and chloroplasts evolved through endosymbiosis, which helps explain their unique cellular features, such as double membranes, circular DNA, ribosomes, and binary fission reproduction. The slides show how mitochondria likely originated from alpha-proteobacteria and chloroplasts from cyanobacteria, through these ancient endosymbiotic events. References are also provided for further reading on endosymbiotic theory.
Tour of Cell
The document provides an overview of cell structure and function:
1) Eukaryotic cells have internal membranes that compartmentalize functions into organelles like the nucleus, mitochondria, chloroplasts, and components of the endomembrane system.
2) The nucleus contains most of the cell's DNA and directs protein synthesis through its genetic material and ribosomes.
3) Organelles like mitochondria and chloroplasts perform specialized metabolic functions by changing energy from one form to another through cellular respiration and photosynthesis respectively.
Chapter Ten Lecture- Mitosis
- Cells can only grow to a certain size before they must divide, as larger cells have trouble transporting nutrients and waste across their membranes. The rate of transport depends on surface area, which increases more slowly than volume.
- Cell division occurs through mitosis and cytokinesis. Mitosis divides the nucleus, while cytokinesis divides the cytoplasm. This ensures each daughter cell has the proper number of chromosomes and identical copies of DNA from the parent cell.
- The cell cycle, regulated by cyclins, coordinates cell growth and division. Cells progress through interphase (G1, S, G2 phases) before entering mitosis (M phase) to accurately replicate DNA and divide. Tight controls ensure cells only grow and divide
IB Biology 1.2 Slides: Ultrastructure of Cells
Electron microscopes have much higher resolution than light microscopes due to the shorter wavelengths of electron beams. Prokaryotes like E. coli have a simple cell structure without compartments, containing a cell wall, plasma membrane, ribosomes, nucleoid, cytoplasm and other structures. They divide via binary fission. Eukaryotes have a compartmentalized cell structure containing organelles like the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, lysosomes, and vacuoles. Organelles in specialized cells like pancreatic and leaf cells are adapted for their functions like enzyme secretion and photosynthesis.

It describes the four major categories of organic molecules and their structures and functions. It also reviews cell structures, organelles, and the differences between prokaryotic and eukaryotic cells. Genetic concepts like DNA, genes, mutations, and Mendelian genetics are summarized. Finally, it defines evolution by natural selection and provides evidence to support the theory of evolution.
IB Biology Core 2.3: Eukaryotic Cells
This document provides information about eukaryotic cells. It includes diagrams and descriptions of key structures in animal cells like the nucleus, cell membrane, mitochondria, endoplasmic reticulum, Golgi apparatus, lysosomes, and ribosomes. It compares prokaryotic and eukaryotic cells, highlights differences between plant and animal cells, and outlines two roles of extracellular components like bone matrix, basement membranes, and cell walls. The document contains links to additional resources for further information.
The cell
1. Multicellular organisms are composed of cells that are organized into tissues, organs, and organ systems.
2. Cells are the smallest and most basic unit of life, and come in two types - prokaryotic and eukaryotic. Prokaryotic cells like bacteria lack nuclei, while eukaryotic cells contain membrane-bound organelles.
3. Cells carry out essential functions through their organelles, including making energy, synthesizing proteins, and replicating. The cell membrane acts as a selective barrier that controls what enters and leaves the cell.
08 ge lecture presentation
This document provides an overview of cell membranes and their structure and functions. It begins by explaining that the plasma membrane forms the boundary of the cell and is selectively permeable. It then discusses how membranes are fluid mosaics composed of phospholipids and proteins. Various types of membrane proteins and their functions are also described, including transport proteins that allow passive and active movement of substances across the membrane. The document concludes by explaining how membrane structure results in selective permeability and the different mechanisms of passive and active transport.
The cell part 1
This document provides information about cells and their structure and function at various levels of organization:
1. Multicellular organisms are made of cells that group together to form tissues, organs, organ systems, and complete organisms.
2. Cells are the smallest and most basic unit of life, and come in two types - prokaryotic and eukaryotic. Eukaryotic cells contain membrane-bound organelles that carry out specific functions.
3. Key cellular components like the cell membrane, nucleus, and organelles are described. The cell membrane regulates what enters and exits the cell, while the nucleus houses genetic material and the nucleolus produces ribosomes.
Endosymbiotic theory
The endosymbiotic theory proposes that organelles like mitochondria and chloroplasts originated from endocytosis of aerobic bacteria and cyanobacteria by ancient prokaryotic cells. Over billions of years, these engulfed bacteria developed a symbiotic relationship with the host cell and transferred genes to the host genome, eventually evolving into permanent organelles. Evidence for this includes mitochondria and chloroplasts containing circular DNA like prokaryotes and mitochondria having 70S ribosomes and protein synthesis mechanisms found in bacteria. However, the theory does not explain the origin of non-photosynthetic organelles and there are differences between bacterial and mitochondrial membranes.
Bio Ch 6 Pwpt
The document summarizes key aspects of cell structure and function. It describes that eukaryotic cells have internal membranes that compartmentalize functions, while prokaryotic cells do not. The main organelles of eukaryotic cells are then outlined, including the nucleus, endomembrane system, mitochondria and chloroplasts, cytoskeleton, and extracellular connections between cells.
Mitochondria role in signaling and innate immunity
This document summarizes Sandeep Kumar's presentation on the role of mitochondria in signaling and innate immunity. It discusses how mitochondria regulate apoptosis through the intrinsic pathway and the role of mitochondrial proteins like MAVS, BAX and BAK. It explains how mitochondria are involved in antiviral immunity through the RIG-I-MAVS signaling pathway and antibacterial immunity by enhancing mROS production. Finally, it notes that mitochondria function as hubs for innate immune signaling and the release of mitochondrial DAMPs that activate the immune response.
Lecture 1 basic molecular biology
Molecular biology is the study of biology at a molecular level.
In broad sense, the study of gene structure and functions at the molecular level to understand the molecular basis of hereditary, genetic variation, and the expression patterns of genes.The field overlaps with other areas of biology and chemistry, particularly genetics and biochemistry.
Chapter 06 A Tour of the Cell

Lect 4-&-5 cells-bsc-1010_f13_jc
This document provides an outline and overview of key concepts about cells. It begins by defining a cell and describing the main types - prokaryotic and eukaryotic. It then discusses the main components of cells, including the cytoplasm, organelles, cytoskeleton, cell wall, extracellular matrix, and cell junctions. For each topic, it provides brief explanations and examples. Interactive questions are included throughout to test understanding. The goal is to introduce the fundamental building blocks and structures that make up prokaryotic and eukaryotic cells.
Manipulating proteins
1. Immunoprecipitation is a technique used to isolate a protein of interest along with any interacting proteins from a mixture. It involves using an antibody against the target protein to form an immune complex, which is then isolated using a secondary antibody or protein A/G.
2. Immunogold labeling localizes proteins in cells and tissues using antibodies tagged with gold particles and visualized with electron microscopy. It was used in one study to quantify serotonin receptor subtypes in post-mortem brain samples from suicide victims versus controls.
3. Western blotting separates proteins by gel electrophoresis then transfers them to a membrane where antibodies are used to detect specific proteins. It allows visualization and quantification of proteins.

Cell Membrane Structure and Function.ppt
The plasma membrane is selectively permeable and allows some substances to pass through more easily than others. It contains phospholipids arranged in a bilayer with hydrophobic tails interacting in the middle and hydrophilic heads facing outwards. Embedded proteins can be integral and span the entire membrane or peripheral and attach to surface. The fluid mosaic model describes the membrane as a fluid structure with phospholipids and proteins able to move laterally. Transport across the membrane can be passive via diffusion, osmosis, and facilitated diffusion or active via protein pumps and requires cell energy. Endocytosis and exocytosis involve vesicle transport across the membrane.
