A planarian is free-living flatworm that lives in fresh water. Planarians are organisms that live in freshwater. Planarians are part of the metazoan phylum. Animals in the metazoan like jellyfish have the ability to regenerate (Raymond 511-512). Planarians are closely related to animals like jellyfish and starfish. These animals shared the same special ability to regenerate; starfish are able to regenerate their arm when it is cut off. Jellyfish are able to regenerate their stinger when cut off (Li

Animal Cell Cells are the beginning of everything. Every living thing is composed and made from cells. Cells are the smallest unit of organization that we know of. There are two major categories of cellular organization in eukaryotic cells. Those parts which are “membrane bound”‚ called organelles and those which are not “membrane bound”. Every aspect of the cell is important because each part or organelle’s structure is unique to its function. Non membrane bound organelles‚ are those which provide

October 2014 Cell Division Mitosis Abstract Mitosis and Meiosis: Cells can be divided in unicellular organisms or in multi-cellular organisms. DNA controls the cell division. Bacteria reproduce by a process called binary fission. Bacteria have one chromosome that’s attached to the cell membrane. The chromosome replicates and the two copies separate as the cell grows. Over a period of time this one cell makes two cells. Eukaryotes do the process of mitosis. In mitosis‚ each daughter cell gets about

Negative feedback in living organisms Negative feedback is a principle which is used by the body in order to return systems to its normal level; it does this by turning the corrective measures off. Homeostasis uses the principle of negative feedback in order to maintain a constant internal environment. There are a number of different examples of negative feedback such as thermoregulation‚ regulation of blood glucose and the regulation of water potential. The control of the heartbeat can also use

structure of these cells is a flying disk shaped like a donut‚ this is so maximum haemoglobin can be carried allowing maximum amount of oxygen to be transported. Sperm cells A sperm cell is the male reproductive cell that carries the male portion of chromosomes and deoxyribonucleic acid (DNA) information to be fused with the female egg or ovum. The sperm cell carries various amount of heredity information inside the cell nucleus. There are various ways in which sperm can be transmitted to the

Chapter 3 Cell Structure and Function Section 3.1: Cell Theory: Cells are the smallest building unit of living organisms that can carry out all processes required for life. Almost all cells are too small to see without the aid of a Microscope. Although glass lenses used to magnify images for hundreds of years‚ they were not enough to reveal individual cells. The invention of Compound microscope was in the late 1500s by the Dutch eyeglass maker Zacharias Janssen. In 1665‚ the English scientist
