Cell organelles(chpt6)
The document summarizes the structure and function of eukaryotic cells and their organelles. It discusses that cells have three main jobs: 1) make energy through cellular respiration and photosynthesis using mitochondria and chloroplasts, 2) make proteins using instructions from DNA and structures like the nucleus, ribosomes, ER and Golgi apparatus, and 3) make more cells through DNA replication and cell division aided by the nucleus and centrioles. The organelles each have specialized structures and functions that allow the cell to carry out these essential life processes.
Cell organelles
The document lists and describes 9 major cell organelles:
1. The nucleus, which contains DNA and RNA and controls the cell.
2. The endoplasmic reticulum, which has two kinds - rough and smooth - and is involved in protein transport and lipid/toxin processing.

The main organelles such as the cell membrane, nucleus, mitochondria, lysosomes, vacuoles, endoplasmic reticulum and Golgi apparatus are introduced along with their functions. It also summarizes that cells must generate energy, build proteins, transport materials and replicate to carry out the functions of life.
Lesson 2.1
This document discusses cell structure and function. It introduces the cell theory that all organisms are composed of cells, cells are the smallest living things, and cells only arise from pre-existing cells. It then describes the common structures of animal and plant cells including the nucleus, cytoplasm, plasma membrane, organelles like the endoplasmic reticulum, Golgi apparatus, lysosomes, mitochondria, chloroplasts, and cell wall. The functions of these structures are also outlined.
CELL
The document summarizes key aspects of animal and plant cell structure and function. It notes that cells were discovered in 1665 and range between 1-100 micrometers. It describes that animal cells are enclosed by a plasma membrane and contain a nucleus and organelles, while plant cells have a cell wall in addition.

Agribonds for finance –comoros perspective
The document discusses using agricultural bonds (agri-bonds) to finance development in the agriculture sector in Comoros. Comoros has a small population and economy but relies on imports for 40% of its food. It aims to boost domestic food production through partnerships with organizations like the UN Food and Agriculture Organization. The writer proposes creating an agri-bond issued by the Islamic Development Bank to raise capital from multilateral organizations, private sector players, and individuals via mobile money. The funds would support small producers through advisory services and market access to diversify production, boost food security, and reduce poverty in Comoros. Repayments from crop sales would repay the bond holders over time.

Cells are the basic building blocks of all living things. They come in two main types - prokaryotic and eukaryotic. The main parts of a cell include the plasma membrane, cytoplasm, and organelles. The cytoplasm contains cytosol and various organelles that carry out important functions. Organelles can be non-membranous like the cytoskeleton or membranous like the nucleus, endoplasmic reticulum, Golgi apparatus, lysosomes, and mitochondria. The plasma membrane separates the intracellular and extracellular environments and regulates what enters and exits the cell.
Cellstructure
This document provides an overview of cell structure and function. It discusses that cells are the basic unit of life and have organelles that each perform essential jobs. The three main jobs of cells are to generate energy through cellular respiration and photosynthesis using mitochondria and chloroplasts, produce proteins using the nucleus, ribosomes, ER and Golgi apparatus to carry out DNA instructions, and replicate by dividing DNA and organelles between new daughter cells using the nucleus and centrioles. By understanding the roles of different organelles, we can see how cells perform all the necessary functions of life.

The document discusses the structures and functions of eukaryotic cells. It describes organelles such as the nucleus, mitochondria, chloroplasts, endoplasmic reticulum, Golgi apparatus, lysosomes, peroxisomes, cytoskeleton and centrioles. These organelles allow cells to carry out specialized functions like protein production, energy production, transport of materials, waste disposal, structure and cell division. The endosymbiotic theory is presented to explain the origins of mitochondria and chloroplasts from ancient bacteria.
Understanding the prokaryote, plant and animal cell
Prokaryote cells contain structures like capsules, flagella, cell walls, and plasmids that help with protection, locomotion, and carrying genetic material. Animal cells contain organelles like the nucleus, mitochondria, Golgi bodies, and endoplasmic reticulum that allow functions like DNA control, energy production, protein packaging, and transport. Plant cells share some organelles with animal cells but also contain chloroplasts and cell walls which enable photosynthesis and provide structure.
Eykaryotes
There are two main types of cells - prokaryotic and eukaryotic cells. Prokaryotic cells like bacteria do not have a nucleus or membrane-bound organelles. Eukaryotic cells have a nucleus enclosed in a nuclear envelope and membrane-bound organelles like the mitochondria and chloroplasts. Mitochondria and chloroplasts were originally free-living bacteria that were engulfed by early eukaryotic cells in a process called endosymbiosis, providing both cells with evolutionary advantages. Eukaryotic cells have complex internal structures like the nucleus, endoplasmic reticulum, Golgi apparatus and lysosomes that allow them to produce proteins, package and transport materials within the cell.

This document summarizes several key cellular organelles: the endoplasmic reticulum, Golgi body, lysosomes, mitochondria, nucleus, and ribosomes. It describes the endoplasmic reticulum as a structure that stores calcium and aids in protein synthesis and lipid metabolism. The Golgi body processes and sorts proteins from the endoplasmic reticulum for transport. Lysosomes function as the cell's digestive system to degrade internal and external materials. Mitochondria generate the chemical energy stored in ATP. The nucleus contains the cell's DNA and controls gene expression and protein synthesis. Ribosomes are the sites of protein synthesis by reading mRNA sequences.
