Cells were first observed in the late 1600s by Anton van Leeuwenhoek using a single-lens microscope. He discovered microscopic plants, animals, and other organisms that he called "animalcules." The cell theory, developed in the 1830s and 1840s by Schleiden, Schwann, and Virchow, established that all living things are made of one or more cells and that cells are the basic unit of structure and function in living things. Modern microscopes like electron microscopes can magnify specimens up to tens of millions of times using electromagnetic lenses or beams instead of glass lenses.

The document is a guided worksheet about cells that asks questions to help students learn about the key discoveries and scientists involved in the development of the cell theory. It covers topics like when the first microscope was invented, the differences between simple and compound microscopes, early observers of cells like Anton van Leeuwenhoek, later discoveries by Schleiden, Schwann and Virchow, and how different types of microscopes like light and electron microscopes work to produce magnified images of cells.
4. Cell Structure and Function
1) Cell biology is the study of cells, the fundamental unit of life. Key discoveries included Hooke observing cells in 1665 and van Leeuwenhoek improving microscopy. The cell theory established that cells are the basic unit of life.
2) Microscopy revolutionized cell biology by allowing observation of subcellular structures. Light microscopes use visible light while electron microscopes use beams of electrons for higher magnification.
3) Key cellular structures include the nucleus that houses DNA, organelles like mitochondria and chloroplasts that generate energy, and the endomembrane system involved in protein transport and modification.
Cell theory
The development of the cell theory involved contributions from several scientists using microscopes. Robert Hooke first observed cells when examining cork through a microscope in 1665 and coined the term "cell". Anton van Leeuwenhoek later discovered single-celled organisms which he called "animalcules" while examining pond water with a microscope. In the 1830s, Matthias Schleiden and Theodor Schwann concluded that plants and animals, respectively, are composed of cells. Their work established that cells are the fundamental unit of all living things.
Cell Theory
1. The cell theory states that the cell is the basic unit of life, all living things are made of cells, and cells come from pre-existing cells.
2. Anton van Leeuwenhoek invented the first microscope and was the first to observe bacteria and protists. Matthais Schleiden and Theodor Schwann contributed to the cell theory by stating that plants and animals are made of cells, respectively.
3. Rudolph Virchow completed the cell theory by discovering that cells can only arise from pre-existing cells.

The document discusses the cell theory, which has three main parts: 1) the cell is the basic unit of life, 2) all living things are made of cells, and 3) cells come from pre-existing cells. Many scientists contributed to the development of the cell theory, including Anton van Leeuwenhoek who invented the first microscope and observed bacteria and protists, Robert Hooke who observed "cells" in cork, and Theodor Schwann and Matthais Schleiden who stated that plants and animals are made of cells, respectively. Rudolph Virchow further discovered that all cells come from pre-existing cells, cementing the cell theory.
Unit 3 - 7.1 Cell Discovery and Theory
The microscope enabled the discovery that all living things are made of cells. In 1665, Robert Hooke used a simple microscope to observe box-shaped structures in cork that he called "cells". In the late 1600s, Anton van Leeuwenhoek used an improved microscope to observe living organisms in pond water and milk. Over subsequent decades, scientists including Matthias Schleiden, Theodor Schwann, and Rudolf Virchow contributed observations that led to the accepted Cell Theory - that all living things are composed of cells, cells are the basic unit of structure, and cells come from pre-existing cells. More advanced microscopes like electron microscopes have since allowed scientists to study cells in even greater detail.

In biology, cell theory is a scientific theory first formulated in the mid-nineteenth century, that living organisms are made up of cells, that they are the basic structural/organizational unit of all organisms, and that all cells come from pre-existing cells.
Cell theory.pptx
Living organisms have the characteristics of feeding, transporting, respiration, excretion, motion, sensation and reproduction. There are two types of organisms: unicellular organisms which consist of a single cell like amoebas and bacteria, and multicellular organisms which consist of many cells like humans, whales and trees. Cells are the basic unit of structure and function in organisms and they vary greatly in shape, size, and function depending on their role. Scientists like Van Leeuwenhoek, Schleiden, Schwann, and Virchow made important discoveries that led to the development of the cell theory which established that all living things are made up of one or more cells.

Biology (don't know what to name the title )
The document discusses cells and microscopes. It summarizes that cells are the basic units of life and microscopes allow us to study cells. There are two main types of microscopes - compound microscopes, which use two lenses and are used in schools, and electron microscopes, which do not use lenses and can study extremely small objects. The discovery of cells took a long time because early scientists did not have powerful microscopes to observe cells directly.
7.1 cell discovery and theory
The microscope enabled the discovery of cells. In 1665, Hooke observed box-shaped structures in cork which he called "cells". Van Leeuwenhoek later saw living organisms in pond water and milk using an improved microscope. In the 1830s, scientists established that plants and animals are composed of cells, and that cells only arise from pre-existing cells (Cell Theory). Modern compound and electron microscopes allow detailed study of prokaryotic and eukaryotic cell structures and organelles.

Rudolf Virchow later determined that new cells are produced from existing cells, establishing the three main concepts of cell theory - that all living things are composed of cells, cells are the basic functional units of life, and new cells arise from preexisting cells.
Celltheory and its types
Robert Hooke was the first to observe cells in 1665 when he examined a thin section of cork under a microscope. He saw structures that resembled a honeycomb and called them cells. Later, in 1674, Anton van Leeuwenhoek discovered tiny living things in pond water using a microscope. Over time, the observations of many scientists led to the development of the Cell Theory: (1) all living things are made of cells, (2) cells are the basic units of structure and function, and (3) new cells are produced from existing cells.

Algebraic expressions and equations are introduced along with rules for manipulating integers and solving different types of equations.
Mixed Number Notes For Web
The document discusses adding and subtracting mixed numbers. It explains that a mixed number contains a whole number and a fraction. It provides steps for converting between improper fractions and mixed numbers, and guidelines for subtracting mixed numbers from whole numbers or other mixed numbers. Examples are given for adding and subtracting mixed numbers with different denominators or those requiring simplification.
Chemical Compounds In Cells Outline
I. Chemical compounds in cells are made of elements or combinations of elements. Elements cannot be broken down further, while compounds contain two or more elements chemically bonded together. There are organic and inorganic compounds, with organic compounds containing carbon and usually associated with living things. The four main groups of organic compounds are carbohydrates, lipids, proteins, and nucleic acids, each made up of certain elements and serving important cellular functions.
Power Point Verb Tense
The document discusses verb tenses in English. There are three simple tenses: present, past, and future. The present tense follows rules about adding "s" or "es" to verbs depending on their ending when the subject is singular. The past tense typically adds "ed" but has special rules for doubling consonants or dropping "e". The future tense uses the basic verb form with the helping verbs "will" or "shall".
N) Multiply Integers Day 1
The document provides instruction on multiplying integers. It explains that multiplication is repeated addition and presents rules for determining the sign of the product when multiplying integers. Examples are worked through step-by-step using models to represent multiplication as groups of numbers. Practice problems are provided for students to simplify expressions involving integer multiplication.
Moving Cellular Materials Power Point
All cells take in nutrients and expel waste through the cell membrane. The cell membrane is selectively permeable, allowing some substances to pass through passively via diffusion, osmosis, or facilitated diffusion without using energy. Other substances require active transport using transport proteins and cellular energy to move against the concentration gradient into or out of the cell. There are two main types of active transport: endocytosis which surrounds and takes material into the cell, and exocytosis which expels material out of the cell.
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.
A D D I N G I N T E G E R S
This document contains examples and explanations for adding integers on a number line. It includes 4 worked examples of adding integer expressions using a number line. It then provides rules for adding signed numbers and directions for creating a foldable with 3 flaps explaining the rules. There are also practice problems and word problems for students to practice adding integers.
Chapter 2 Study Guides
1) A mixed number has a whole number part and a fractional part, while an improper fraction has a numerator larger than the denominator.
2) To change between mixed numbers and improper fractions, you can multiply or divide the whole number by the denominator and add or subtract the numerator.
3) When adding, subtracting, multiplying or dividing fractions, you often need a common denominator or need to use reciprocals.
Cell Organelle Notes
Cells have a cell membrane that controls what enters and exits. The nucleus is the control center holding genetic material and telling the cell what to do. Organelles like mitochondria and chloroplasts have specific functions - mitochondria convert energy while chloroplasts capture sunlight to make food in plant cells. Cells are the basic units that make up higher levels of organization like tissues, organs, and systems within complex organisms.
Cell Organelle Cloze Notes
The nucleus is the control center of the cell and contains DNA. It is surrounded by a membrane. Ribosomes produce proteins and may be free in the cytoplasm or attached to the endoplasmic reticulum. The endoplasmic reticulum transports molecules through a series of membranes and may be rough or smooth. Mitochondria are the powerhouses of the cell and convert energy. Vacuoles store waste and other materials. Lysosomes break down materials as the cell's waste management system. Microtubules and microfilaments make up the cytoskeleton to support the cell.
Chemical Compounds In Cells Power Point
There are four main types of organic compounds found in cells: carbohydrates, lipids, proteins, and nucleic acids. Carbohydrates provide short-term energy and structural support in plants. Lipids store long-term energy and form cell boundaries. Proteins regulate cell processes and build cell structures. Nucleic acids carry hereditary information and are used to make proteins.
Chapter 1 Study Guide
The document discusses the order of operations (PEMDAS) and provides examples of how to evaluate expressions and solve equations. It explains that parentheses, exponents, multiplication/division from left to right, and addition/subtraction from left to right have precedence based on the PEMDAS acronym. Integers, absolute value, adding, subtracting, multiplying, and dividing integers are also covered along with writing algebraic expressions and solving different types of equations.
P E R F E C T T N E S E Power Point 2
There are three perfect tenses in addition to the three simple tenses of present, past and future. The present perfect, past perfect and future perfect tenses are formed using a helping verb of have and a past participle. The present perfect uses has or have, the past perfect uses had, and the future perfect uses will have to indicate the tense. Examples are provided of how to form sentences in each perfect tense.
Unlike Den. Notes For Web
To add or subtract fractions with unlike denominators, there are 5 steps:
1) Write the problem vertically
2) Find a common denominator that both denominators divide into
3) Add or subtract the numerators
4) Keep the original denominators
5) Simplify the resulting fraction if possible
Examples of adding, subtracting, and finding a common denominator are provided.
Adding And Subtracting Fraction Notes For Web
To add or subtract fractions with like denominators, add or subtract the numerators and keep the same denominators, simplifying the resulting fraction if needed. There are two types of fractions: proper fractions where the numerator is smaller than the denominator, and improper fractions where the numerator is greater than or equal to the denominator. For improper fractions, the answer must be simplified by dividing.
