CELL OBSERVATION LAB By Alexandra Escaja-Heiss, Ashley Reeves, & Christine Constant Period G1/B3a - Living Systems 10/22/15 Purpose To identify the difference between plant and animal cells, recognize their structures, and to better understand the various functions of those cell organelles. II. Background In 1665 Robert Hooke used an early light microscope to look at a thin slice of cork. Under the microscope the cork looked to have thousands on empty chambers, which

Plant and Animal Cells I. Introduction All organisms in life are composed of at least one or more cells. Cells are the basic units of life. There are three main features of a cell. First, all organisms consist of one or more cells. Second, cells are the smallest units of life and third, cells arise only from preexisting cells. These three facts are referred to as the cell theory. All cells can be categorized into two basic cell types. They are prokaryotic and

A cell is the smallest structural and functional unit of an organism. A cell is very complex but also very interesting. They contain many parts to keep them running. In 1664, english scientist Robert Hooke viewed a thin slice of cork through an early microscope. Cork looked like it was constructed of many tiny rooms, he called these cells. At first scientists thought it was just filled with jelly, so they called it protoplasm. But as microscopes were improving over time, looking at cells became

Although animal cells and plant cells are both eukaryotes, they possess many differences in shape, size, and structure. In this lab, our group investigated the question: Do plant cells always tend to be larger in size compared to animal cells? We did this lab in order to learn more about the differences between plant and animal cells by observing their physical properties. It was hypothesized that if we compare human blood cells to onion root cells, then we will observe that the plant cells are larger

the differences between the structure of animal and plant cells In general both animal cells and plant cells have the similar structures, however they do have some differences. Plant cells have a cell wall, this strengthens the cell,it also gives it shape and protects it from infection. Plant cells also have chloroplasts which absorb light energy,this is vital for photosynthesis. Plant cell also have a vacuole, however unlike the ones found in animal cells they are much larger. Vacuoles store food

The structures within an animal cell are described as follows: Plasma Membrane or Cell Membrane: This is a thin membranous layer which surrounds the cell and acts as a barrier, it works to separate the contents within the cell from its external environment as well as from other cells. It 's structure is important as it provides structural support and protection of components within it as is is made up of a double membrane layer or phospholipid bilayer. It works likes a gatekeeper of pathway so

Cells are the basic unit of structure and function in living things. If something is not made of cells, it is not alive. There are different types of cells. The two major groupings of cells prokaryotes and eukaryote. The two main types of eukaryotes are plant and animal cells. Plant and animal cells have many similarities but a few important differences. Animal cells all share certain characteristics but vary from there. Plant cells all share certain characteristics but vary from there. Cells are

the microstructure of a typical animal cell and the functions of the main cell components. A typical animal cell is seen as a tiny, three dimensional sac which is in fact made up of many components, each as important as the other. The microstructure of an animal cell was in fact uncovered mainly through the use of both cell fractionation and electron microscopy. Each main component has its own, individual function which helps a cell to function and maintains the cell membrane. The components that

Cells and Stem Cells 1. The Diagram of a typical Animal cell (not drawn) 2. In your own words, describe and explain what each part of the cell does Vacuole: Vacuoles are used as storage inside the cell, they are found in both the animal cell and the plant cell, but are larger in plant cells because they have to store lots of water for the actual plant to survive and thrive. Vacuoles store food, water and nutrients to help keep the cell alive. The vacuole can also store the waste that the

Cells are the basic unit of life, every living thing is made up of them (Robson). Cells are the smallest unit of life, they consist of a cytoplasm and a membrane (Wiki). Cells can be unified as either unicellular or multicellular (Wiki). Multicellular cells consist of plant and animal cells, the number of cells in each plant and animals vary from species to species (Wiki). Plant and animal cells have many similarities and differences such as their size, what they are made up of, and their cell walls
