Here are the key differences between prokaryotic and eukaryotic cells:
Prokaryotic Cells:
- Lack a nucleus and other membrane-bound organelles
- Have circular DNA located in the nucleoid region
- Typically smaller than eukaryotic cells
- Include bacteria and archaea
Eukaryotic Cells:
- Have a clearly defined nucleus enclosed in a nuclear membrane
- Contain membrane-bound organelles such as the mitochondria, chloroplasts, Golgi apparatus, endoplasmic reticulum, etc.
- Have linear DNA packaged with histone proteins into chromosomes within the nucleus
- Include plants, animals, fungi, protists

Organelles from cells
Prokaryotic organelles include the plasma membrane, which controls what enters and exits the cell, the nucleoid which contains DNA, ribosomes which assemble proteins, the cell wall which protects the cell, and flagella which aid movement. Eukaryotic organelles include mitochondria which generate energy, the nucleus containing genetic material, the endoplasmic reticulum which transports materials, the Golgi apparatus which packages proteins, microtubules which transport vesicles and organelles, vacuoles which store materials, and lysosomes which break down waste.
Plant cells
The document defines and describes the key organelles and structures found within plant cells, including the cell wall, cell membrane, chloroplasts, golgi bodies, mitochondria, nuclear membrane, nucleus, ribosomes, rough endoplasmic reticulum, smooth endoplasmic reticulum, and vacuoles. The cell wall provides structure and support, while the cell membrane regulates what passes in and out. Chloroplasts use sunlight for photosynthesis, and mitochondria generate energy. The golgi body packages proteins and carbohydrates, and the nucleus contains DNA and controls cell functions. Ribosomes produce proteins, and the endoplasmic reticulum transports materials through the cell.

Here is a draft paragraph you could write as a cell:
As a cell, I am the basic unit of structure and function that makes up complex organisms. Cells come together to form tissues, which then make up organs. Groups of organs working together are called organ systems. There are two main types of organisms - unicellular organisms that are single cells, and multicellular organisms made of many cells like humans. I am produced through cell division, where my parent cell divides into two new daughter cells. My main structures include a cell membrane that encloses my cytoplasm, a nucleus that controls my functions, mitochondria that provide me energy, and a vacuole for storage. Together with other cells, I form the basic tissues, organs
Ths general biology unit 3 cell processes cell membrane transport notes_v1516
Cell membranes allow transport of molecules into and out of cells through diffusion, facilitated diffusion, osmosis, and active transport. Diffusion and facilitated diffusion move particles from high to low concentration without energy, while osmosis moves water molecules and active transport moves particles against concentration gradients, requiring ATP energy. Cells regulate transport to take in useful nutrients and remove waste.
Biology Unit 2 Notes: Cell Membrane Transport
This document discusses cell membrane transport, including the types of transport mechanisms cells use to move nutrients and molecules in and out. It describes diffusion, facilitated diffusion, and osmosis as passive transport mechanisms that move particles down concentration gradients without requiring energy. Active transport is defined as the active movement of particles against a concentration gradient, which does require energy in the form of ATP. Different osmotic environments are also defined based on the relative concentration of water inside and outside the cell.
Unit 2 Cells, Tissues & Membranes
This document contains lecture slides about cells, tissues, and membranes. It begins by defining cells and tissues, with cells making up tissues and carrying out life's functions. Tissues are grouped into four primary types - epithelial, connective, nervous and muscle. Epithelial tissues line and cover surfaces, and are classified based on cell layers and shapes. Connective tissues are found throughout the body and bind other tissues together. They include bone, cartilage, fibers and adipose tissue. The document then goes into detail about the structures and functions of cells, membranes, organelles and other cellular components.
Animal cells
The document summarizes several key organelles in cells:
- The cytoplasm contains organelles and allows substances to pass in and out of the cell. The nucleus is the largest organelle and contains the cell's genetic information.
- Mitochondria convert food into energy for the cell's use, with more in cells requiring greater energy. The endoplasmic reticulum helps produce and transport proteins, with ribosomes attached in some areas.
- The Golgi complex sorts and ships proteins from the endoplasmic reticulum. Lysosomes digest unneeded proteins and lipids for the cell.

CELL STRUCTURE AND TRANSPORT.pptx
This document discusses cell structure, function, and cellular transport. It begins by defining the cell and outlining the three main points of the cell theory: 1) all living things are made of cells, 2) new cells are produced from existing cells, and 3) the cell is the basic unit of structure and function. It then describes the structure and functions of key cellular components like the plasma membrane, nucleus, cytoplasm, organelles, and ribosomes. The final section discusses cellular transport mechanisms, distinguishing between passive transport (diffusion and osmosis) which moves substances down concentration gradients without energy input, and active transport which requires ATP and transports substances against gradients.
Cells 2013 14
The cell is the basic unit of all living things. Cells contain organelles that allow them to carry out life functions like respiration, protein production, and waste removal. Plant and animal cells differ in structures like the presence of a cell wall and chloroplasts in plant cells. Cells come together to form multicellular organisms through different levels of organization - tissues, organs, organ systems - allowing complex life forms to develop, function and reproduce.

Cells are the basic structural and functional units of all living organisms. The cell theory states that all living things are composed of cells, cells are the basic units of structure and function, and cells only come from pre-existing cells. Cells fall into two main categories - prokaryotes like bacteria that have no organized nucleus, and eukaryotes like plants and animals that have organized nuclei. Eukaryotic cells contain organelles like the nucleus, mitochondria, chloroplasts and more that carry out specialized functions, while prokaryotes lack these structures. Plant and animal cells share some components but differ in structures like plant cells having cell walls and chloroplasts for photosynthesis while animal cells do not.
STRUCTURE OF CELL
Cells are the basic structural and functional units of living organisms. A cell contains a nucleus that holds genetic material and membrane-bound organelles suspended in cytoplasm. There are two main types of cells - prokaryotes and eukaryotes. The cell is surrounded by a membrane and contains a nucleus that houses DNA, organelles like mitochondria and lysosomes, and cytoplasm within which various chemical reactions take place.
