Lab 4: Cell Structures and the Gram Stain Purpose: The purpose of this lab is to familiarize the student with the use of a compound microscope and the Gram Stain test. Students will review a brief video and slides to introduce the compound microscope. Students will also view a video about the Gram Stain procedure and then answer questions related to it. Hypothesis If I look at the slides I will see where the cell wall is and what lies inside it and in the Gram Stain if I watch the video I will

Functionally‚ eukaryotic genomes can be described as much larger and more complex than prokaryotic genomes. This means regulation is a lot more demanding and intensive within the eukaryotic genome. Due to its complex nature‚ eukaryotic gene regulation can bring genetic changes in its product that affect gene expression‚ phenotypic outlook‚ and advances in biotechnology. This can be thought of as an evolutionary advantage to organisms in an unstable environment. Gene regulation in eukaryotes is a

Nucleus- The nucleus is the control center of the cell. This is where DNA is contained. This is like the town hall or the mayor’s office because it is the control center of a town. The nucleus uses DNA like a city uses blueprints to direct the production of protein. Nucleolus- The nucleolus is where ribosome is made and is rich in RNA content. It is located inside the nucleus. A mayor is like this because the mayor makes everything in the town happen. He also works from the town hall‚ or works

the structure of cells related to their function? Cell structures come in various shapes and sizes dependent on their location within an organism and what life sustaining process it carries out. These can range from the globular protein of a red blood cell‚ designed to carry four oxygen molecules at a time to the tail like flagellum of a bacteria designed for mobility and penetration of organs within a body. There are two main types of cells‚ eukaryotic cells which are generally plant and animal

ESSAY ‘The structure and importance of the plasma membrane found within and around all cells’ The plasma membrane surrounds all eukaryotic and prokaryotic cells. Eukaryotic cells have membrane bounded organelles whereas prokaryotic cells do not. The plasma membrane forms the boundary between the cell cytoplasm and the environment. Its function are to allow different environments to be established inside and outside the cell. It also controls the movement of substances into and out of the cell. The cell

1: A BEGINNER’S GUIDE TO THE STUDY OF PLANT STRUCTURE Adonay‚ Jessa and Velos‚ Mary Angelie Biology Program‚ Sciences Cluster University of the Philippines Cebu Lahug‚ Cebu City‚ Philippines ABSTRACT Plants have essential requirements to survive like all other living being. Roots‚ stems‚ leaves‚ and flower serve to help them acquire or provide for these requirements. Plants exposed to different climates pose different arrangement in the structures’ tissues.

between the structure and function of four specialised human cells. The human body is made up of trillions of different cells; all play a huge role in the running and function of the body. They are the foundation of all living things. Each different cell has its own exclusive job. Without cells the human body would simply fail. All cells contain organelles which are the structures of the cells itself‚ organelles have individual functions. This essay will investigate the structure and function

Having the necessary nucleus which holds the cells DNA and produces ribosomes that help in the synthesis of proteins. Surrounding the nucleus is the rough and smooth endoplasmic reticulum. The two help break down and store materials. Rough stores and transports synthesized proteins‚ while smooth stores and transports synthesized lipid‚ steroid hormones
