P1 [pic] Cell membrane - encloses the contents of the cell and regulates the flow of substances into and out of the cell. Mitochondrion - this feature produces a substance called adenosine triphosphate (ATP) which is the carrier of energy in all cells. Centriole - these two features made of hollow tubules play a key role in cell division. Ribosomes - these small‚ granular features of the cell play a key role in the assembly of proteins. Chromosome - During cell division‚ DNA‚ the

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

LAB REPORT 1 - LAB 7 CELL MEMBRANE FUNCTION Marisela Camacho Legarreta June 30‚ 2013 ACTIVITY 1 INTRODUCTION Be aware that all molecules have kinetic energy‚ which means that is an active energy that is always in motion. Molecules move in all different ways and this create an evenly distributed movement which is best known as diffusion. Diffusion is the movement of molecules from a region of their higher concentration to a lower concentration. METHODS Check the reaction of different

Describe the structure and function of the skeleton system’s two distinct are – Axial System and Appendicular skeleton. Axial system The axial skeleton is the portion of the human skeleton that consists of the bones of the head and trunk of an organism. In the human body‚ it consists of 80 bones and is composed of – 29 bones in the head - (8 cranial and 14 facial bones) and then also 7 associated bones (6 auditory ossicles and the Hyoid Bone) 25 bones of the thorax - (the sternum and 24 ribs)

The Structure and Function Relationships of Proteins Proteins are a group of organic compounds whose molecules consist of carbon‚ hydrogen‚ oxygen‚ nitrogen and sometimes sulfur atoms. They are condensation polymers of amino acids that are joined by strong peptide bonds. There are 20 different types of amino acids available‚ and the different combinations of these amino acids give it different structures and specific functions to it. Below in this essay‚ will illustrate the how different structure

Structure & Function of Plants Review: Plant Structure‚ Growth‚ and Development I 1. How does the vascular tissue system enable leaves and roots to function together in supporting growth and development of the whole plant? 2. When you eat the following‚ what plant structure are you consuming? Brussels sprouts‚ celery sticks‚ onions‚ and carrot sticks. 3. Characterize the role of each of the three tissue systems in a leaf. 4. Describe at least three specializations in plant organs and

Animal Cell Organelles & Their Functions 1. Nucleus - The nucleus generally contains the genetic material for the cell. Because it contains the DNA and chromosomes‚ which affect the proteins that determine the activities of the cell‚ the nucleus can be considered to be the cell’s control centre. 2. Cytoplasm - The cytoplasm contains primarily water and protein material. This is where the other cell organelles reside‚ and where most of the cellular activities take place. 3. Cell Membrane - The

healthy and in shape therefore learning more about the muscular system is very interesting. The reproductive system is another wonderful system to study and learn about‚ it is a great part of human life. I find it amazing to learn about the structure and functions of these two body parts and how they actually work together to perform homeostasis. We have so many muscles in our muscular system‚ too many to list. There are three main types of muscles. Cardiac muscles‚ skeletal muscles and smooth muscles
