Cell is the smallest structural and functional unit of living things. An animal cell differs from a plant cell in that animal cells do not have a cell wall or plastids, contain two centrioles in the centrosome, generally lack large vacuoles, and are only able to digest organic compounds rather than produce their own food through photosynthesis like plant cells. The document defines cells and compares the key differences between animal and plant cells.

Cell Organelles Powr Point
Cells come in different sizes and shapes. All cells have a cell membrane which controls what enters and exits the cell, and cytoplasm which is a gel-like material. Only plants, algae, fungi and bacteria have cell walls. The nucleus is the control center of the cell and contains genetic material. Organelles like mitochondria, ribosomes, the endoplasmic reticulum and golgi bodies carry out specific functions within the cell. Mitochondria convert energy from food into a form cells can use, while ribosomes produce proteins and the endoplasmic reticulum transports materials.

Power point presentation of animal cell and plant cell
Plant and animal cells share three basic parts - the cell membrane, nucleus, and cytoplasm. The cell membrane surrounds the cell and separates it from the external environment. The nucleus is located near the center of the cell and controls its activities and facilitates cell division. The cytoplasm is a semi-fluid material found between the nucleus and cell membrane that contains proteins, lipids, carbohydrates, minerals, salts, and water.

Animal cell (project)
The document summarizes key components of animal cells:
- Animal cells contain organelles such as the cell membrane, nucleus, cytoplasm, mitochondria, endoplasmic reticulum, Golgi apparatus, lysosomes, and vacuoles. The cell membrane encloses the cell and is selectively permeable. The nucleus contains DNA and directs protein synthesis. Mitochondria generate ATP to power cellular processes.
- Animal cells differ from plant cells in lacking cell walls, chloroplasts, and having smaller vacuoles. Due to their lack of a cell wall, animal cells can adopt varied shapes while plant cells maintain a rectangular shape.
Cell Biology
The document discusses cell theory and key aspects of cell structure and function:
1) Cell theory states that all living things are made of cells, cells are the basic functional units of life, and all cells come from preexisting cells.
2) A cell membrane surrounds the cell and acts as a selective barrier controlling what enters and exits the cell.
3) The fluid mosaic model describes the cell membrane as a fluid bilayer with embedded proteins that allows for selective permeability and transport of materials.
Cell is the Basic Unit of Life
The word cell is derived from the Latin word “cellula” which means “a little room”
It was the British botanist Robert Hooke who, in 1664, while examining a slice of bottle cork under a microscope, found its structure resembling the box-like living quarters of the monks in a monastery, and coined the word “cells”
Ix ppt CELL- Fundamental unit of life
Robert Hooke first observed "cells" in 1665 when examining thin slices of cork under a microscope. He saw that the cork's structure resembled a honeycomb with many empty box-like cavities. The modern cell theory, developed by Schleiden, Schwann, and Virchow, states that all organisms are composed of one or more cells, cells are the basic units of structure and function, and new cells are produced from existing cells. A cell is surrounded by a membrane and contains a nucleus and cytoplasm, with various organelles that carry out different functions.
Organelles
This document provides information about the structures and organelles found within eukaryotic cells. It discusses the differences between prokaryotic and eukaryotic cells, noting that eukaryotic cells have a nucleus and membrane-bound organelles while prokaryotic cells do not. It then describes the various organelles found in eukaryotic cells and their functions, including the nucleus, mitochondria, chloroplasts, endoplasmic reticulum, Golgi apparatus, ribosomes, vacuoles, and lysosomes. The document concludes by assigning homework to create a drawing of a eukaryotic cell using objects to represent each organelle's job.
Cell Similarities
All cells share several key components: a cell membrane that acts as a barrier between the interior and exterior of the cell and controls what passes in and out, hereditary material in the form of DNA that is copied when cells divide and directs the cell's activities, cytoplasm and organelles that contain the structures and chemicals that allow the cell to function, and they are generally too small to be seen without a microscope.

The slides provide information about Discovery of cell,cell theory,number,size,shape and cell types .Differentiates prokaryotic and eukaryotic cell types and point out major differences in plant and animal cell and also about structure and function of cell organelles
Cells and their organelles
There are two main types of cells: prokaryotic cells which lack membrane-bound organelles and eukaryotic cells which contain organelles enclosed in membranes. Eukaryotic cells can be either animal or plant cells. Both contain organelles such as a nucleus, mitochondria, ribosomes, and endoplasmic reticulum. However, plant cells also contain chloroplasts and have a cell wall and central vacuole, while animal cells do not have these structures. The organelles work together to carry out essential functions like DNA storage, protein production, photosynthesis, and transport within the cell.
Cell: The Basic Unit of Life
1. The history of cell theory began with early observations of cells in the 17th century by Robert Hooke and refinements in the 19th century by Theodor Schwann and Matthias Schleiden.
2. Schwann and Schleiden developed the cell theory which stated that the cell is the basic unit of structure and function in living things.
3. Modern cell theory recognizes that all living things are composed of cells, cells arise from preexisting cells, and the cell is the basic functional unit of life.
Diversity Of Cell Life
1. While all living things are composed of cells that share basic chemistry and genetic code, there are differences in how cells are specialized and how they work together in multicellular organisms.
2. Cells can be unicellular, functioning independently as single-celled organisms, or multicellular, organized into tissues, organs and organ systems. Specialized cells perform different tasks depending on the organism.
3. Osmotic pressure, the pressure caused by water movement across membranes, is regulated to prevent animal cells from bursting through isotonic fluids like blood, while plant cells are protected by cell walls.

Introduction of Human Body & Structure of cell.pptx
Anatomy:
Anatomy is the study of the structure of the body and the physical relationships involved between body parts.
Physiology:
Physiology is the study of how the parts of the body work, and the ways in which they cooperate together to maintain life and health of the individual.
Definition:
Atoms combine to form molecules, of which there is a vast range in the body. The structures, properties and functions of important biological molecules.
Example:
Neon (Ne)
Hydrogen (H)
Argon (Ar)
Iron (Fe)
Calcium (Ca)
Definition:
Cells are the smallest independent units of living matter and there are millions in the body. They are too small to be seen with the naked eye, but when magnified using a microscope different types can be distinguished by their size, shape and the dyes they absorb when stained in the laboratory. Each cell type has become specialized, and carries out a particular function that contributes to body needs.
Cell Wall:
The cell wall is present exclusively in plant cells. It protects the plasma membrane and other cellular components. The cell wall is also the outermost layer of plant cells. It is made up of cellulose. It provides shape and support to the cells and protects.
Cell Membrane:
The cell membrane supports and protects the cell. It controls the movement of substances in and out of the cells. It separates the cell from the external environment. The cell membrane is present in all the cells.
Cytoplasm:
The cytoplasm is a thick, clear, jelly-like substance present inside the cell membrane. Most of the chemical reactions within a cell take place in this cytoplasm. The cell organelles such as endoplasmic reticulum, vacuoles, mitochondria, ribosomes, are suspended in this cytoplasm.
Nucleus:
The nucleus contains the hereditary material of the cell, the DNA. It sends signals to the cells to grow, mature, divide and die. The nucleus is surrounded by the nuclear envelope that separates the DNA from the rest of the cell. The nucleus protects the DNA and is an integral component of a plant’s cell structure.
The nucleolus is the site of ribosome synthesis. Also, it is involved in controlling cellular activities and cellular reproduction.
The nuclear membrane protects the nucleus by forming a boundary between the nucleus and other cell organelles.
Chromosomes play a crucial role in determining the sex of an individual. Humans have 22 pairs of autosomes and one pair of sex chromosomes (XX or XY). Each human cells contain 23 pairs of chromosomes.
The endoplasmic reticulum is involved in the transportation of substances throughout the cell. It plays a primary role in the metabolism of carbohydrates, synthesis of lipids, steroids and proteins.
Golgi bodies are called the cell’s post office as it is involved in the transportation of materials within the cell.
Ribosomes are the protein synthesizers of the cell.
The mitochondrion is called “the powerhouse of the cell.” It is called so because it produces ATP – the cell’s energy currency.
Comparing Plant Cells
The document compares plant and animal cell structures under a microscope. It notes that one substance observed was prokaryotic (the Elodea plant cell), as it lacked a nucleus, while the single-celled organism was eukaryotic as it contained a nucleus. Both cell types contain organelles like the cytoplasm, cell membrane, vacuole and mitochondria. The plant cell was better suited for study due to its large size and visible cytoplasmic streaming.

The document discusses cells and their structures. It notes that all living things are made of cells, which are the smallest unit of life. Cells come in many shapes and sizes and have different organelles that allow them to function. Key organelles include the nucleus, cell membrane, mitochondria, chloroplasts, and vacuoles. Plant and animal cells differ in that plant cells have cell walls, chloroplasts, and usually one large central vacuole, while animal cells lack cell walls and have multiple smaller vacuoles.
Self learning material
This document provides information about cell structure and function from a student's self-learning material. It discusses the variation in number, shape, and size of cells and describes the structure of a generalized cell, including the cell membrane, cytoplasm, nucleus, and various organelles. It compares the structures of plant and animal cells and explains cell division and growth. The key points covered are that cells are the basic structural and functional units of life, they vary in number, shape, and size, and all cells have a basic structure including a cell membrane, cytoplasm, and nucleus despite differences.
Elodea Plant Cell Structure
Elodea is an aquatic plant that is well-suited for studying plant cell structures under a microscope due to its large, bright green leaves and visible cytoplasmic streaming. The cells in Elodea plants are very large, allowing observation of organelles like chloroplasts and observation of their movement throughout the cell via cytoplasmic streaming. This makes Elodea a popular specimen for demonstrating plant cell structure using a standard light microscope.
Module 4-plant-and-animal-cell-discussion
This document provides an overview of cytology, including the objectives to identify cell structures, differentiate organelles in plant and animal cells, and understand the importance of cells. It reviews that cells are the basic unit of life and microscopy is used to view cells. The main types of cells - prokaryotes and eukaryotes - are introduced. Key organelles like the nucleus, cell membrane, and chloroplasts are examined in both plant and animal cell diagrams. The functions of these parts are discussed along with how cells reproduce through cell theory.

- 7. The Difference Of Animal Cell With Plant Cell In animal cell there is no cell wall and plastids. Animal cell have to centrioles in the centrosome, generally do not have vacuoles, if there are only small vacuoles. While in plant cell do not have lysosomes and centrioles. Based on morphology, the most outer layer of animal cell is cell membrane. Meanwhile the most outer layer of plant cell is cell wall. Based on physiology, plant cell has ability to compose simple anorganic compounds to be carbohydrate, lipid, and protein. On the contrary, animal cell only digests organic compounds that come from another plant or animal.
