Tis close match of each mouse to its environment is vital for survival since hawks herons and other sharp-eyed predators periodically scan the landscape for food.
Evolution is the fundamental principle of biology and the core theme of this book. Although biologists know a great deal about life on Earth many mysteries remain. When questions occur to you as you observe the liv- ing world you are already thinking like a biologist. This mouse has a much darker back side and face than mice of the same species that inhabit sand dunes.
The community in our forest ecosystem includes many kinds of trees and other plants various animals mushrooms and other fungi and enormous numbers of diverse microorganisms which are living forms such as bacteria that are too small to see without a microscope. Each of these forms of life is called a species. We can also see the scale of the entire biosphere which consists of all life on Earth and all the places where life exists: most regions of land most bodies of water the atmosphere to an altitude of several kilometers and even sediments far below the ocean foor.
A deciduous forest is an example of an ecosystem as are grasslands deserts and coral reefs. An ecosystem consists of all the living things in a particular area along with all the nonliving components of the environment with which life interacts such as soil water atmospheric gases and light.
For example our forest includes a population of sugar maple trees and a population of white-tailed deer. A community is therefore the set of populations that inhabit a particular area. Each campbell biology in focus 3rd edition pdf download the maple trees and other plants in the forest is an organism and so is each deer frog beetle and other forest animals.
The soil teems with microorganisms such as bacteria. Imagine zooming in from space to take a closer and closer look at life on Earth. It is spring in Ontario Canada and our destination is a local forest where we will eventually narrow our focus down to the molecules that make up a maple leaf.
Figure campbell biology in focus 3rd edition pdf download. A maple leaf is an example of an campbell biology in focus 3rd edition pdf download a body part that carries out a particular function in the body, campbell biology in focus 3rd edition pdf download. Stems and roots are the other major organs of plants. The organs of complex animals and plants are organized into organ systems each a team of organs that cooperate in a larger function.
Organs consist of multiple tissues. Each tissue is a group of cells that work together performing a specialized function. The leaf shown here has been cut on an angle. The honeycombed tissue in the interior of the leaf left side of photo is the main location of photosynthesis the process that converts light energy to the chemical energy of sugar.
The pores through the epidermis allow entry of the gas CO 2 a raw material for sugar production, campbell biology in focus 3rd edition pdf download.
Some organisms are single cells while others are multicellular. A single cell performs all the functions of life while a multicellular organism has a division of labor among specialized cells. Here we see a magnifed view of cells in a leaf tissue. As tiny as these cells are you can see that each contains numerous green structures called chloroplasts which are responsible for photosynthesis.
Chloroplasts are examples of organelles the various functional components present in cells. This image taken by a powerful microscope shows a single chloroplast. Our last scale change drops us into a chloroplast for a view of life at the molecular level.
A molecule is a chemical structure consisting of two or more units called atoms represented as balls in this computer graphic of a chlorophyll molecule. Chlorophyll is the pigment molecule that makes a maple leaf green and it absorbs sunlight during photosynthesis. Within each chloroplast millions of chlorophyll molecules are organized into systems that convert light energy to the chemical energy of food.
Viewed this way we see that at each level novel properties emerge that are absent from the preceding one. Tese emergent properties are due to the ar- rangement and interactions of parts as complexity increases. For example although photosynthesis occurs in an intact chloroplast it will not take place in a disorganized test-tube mixture of chlorophyll and other chloroplast molecules. Isolated components of living campbell biology in focus 3rd edition pdf download acting as the objects of study in you through photographs illustrating the hierarchy of biologi- cal organization.
Reductionism is a powerful strategy in biology. For example by studying the molecular structure of DNA that had been extracted from cells James Watson and Francis Crick inferred the chemical basis of biological inheritance. Emergent properties are not unique to life. Compared to such nonliving examples however the unrivaled complexity of biological systems makes the emergent proper- ties of life especially challenging to study.
T o fully explore emergent properties biologists today complement reductionism with systems biology the explora- tion of a biological system by analyzing the interactions among its parts.
A single leaf cell can be considered a system as can a frog an ant colony or a desert ecosystem. By examining and modeling the dynamic behavior of an integrated network of components systems biology enables us to pose new kinds of questions. Consider the leaf in Figure 1. More generally analyzing a biological structure gives us clues about what it does and how it works, campbell biology in focus 3rd edition pdf download. Conversely knowing the function of something provides insight into its structure and organization.
Many examples from the animal kingdom show a correlation between structure and function including the hummingbird Figure 1. In fact the activities of organisms are all based on the activities of cells. For instance the movement of your eyes as you read this sentence results from the campbell biology in focus 3rd edition pdf download of muscle and nerve cells, campbell biology in focus 3rd edition pdf download.
Even a process that occurs on a global scale such as the recycling of carbon atoms is the cumulative product of cellular functions including the photosynthetic activity of chloroplasts in leaf cells. All cells share certain characteristics. For instance every cell is enclosed by a membrane that regulates the passage of materi- als between the cell and its surroundings.
Nevertheless we rec- ognize two main forms of cells: prokaryotic and eukaryotic. Te cells of two groups of single-celled microorganisms—bacteria singular bacterium and archaea singular archaean—are prokaryotic.
All other forms of life including plants and ani- mals campbell biology in focus 3rd edition pdf download composed of eukaryotic cells. A eukaryotic cell contains membrane-enclosed organelles Figure 1.
For example the chlo- roplast in Figure 1. In contrast to eukaryotic cells a prokaryotic cell lacks a nucleus or other membrane- enclosed organelles. Furthermore prokaryotic cells are gener- ally smaller than eukaryotic cells as shown in Figure 1. This model shows each atom in a segment of DNA. Made up of two long chains of building blocks called nucleotides a DNA molecule takes the three-dimensional form of a double helix.
Single strand of DNA. These geometric shapes and letters are simple symbols for the nucleo- tides in a small section of one chain of a DNA molecule. Genetic information is encoded in specific sequences of the four types of nucleotides. Their names are abbreviated A T C and G. DNA Structure and Function Each time a cell divides the DNA is frst replicated or copied and each of the two cellular ofspring inherits a complete set of chromosomes identical to that of the parent cell. Each chro- mosome contains one very long DNA molecule with hundreds or thousands of genes each a stretch of DNA arranged along the chromosome.
Transmitted from parents to ofspring genes are the units of inheritance. Each of us began as a single cell stocked with DNA inherited from our parents. Te replication of that DNA during each round of cell division transmitted copies of the DNA to what eventually be- came the trillions of cells of the human body.
As the cells grew and divided the genetic information encoded by the DNA di- rected our development Figure 1, campbell biology in focus 3rd edition pdf download. Te molecular structure of DNA accounts for its ability to store information.
A DNA molecule is made up of two long chains called strands arranged in a double helix. Each chain is made up of four kinds of chemical building blocks called nucleotides abbreviated A T C and G Figure 1.
Te way DNA encodes information is analogous to how we arrange the letters of the alphabet into words and phrases with specifc meanings. Te word rat for example evokes a rodent the words tar and art which contain the same letters mean very diferent things. We can think of nucleotides as a four-letter alphabet. Specifc sequences of these four nucleotides encode the information in genes. In cells that are preparing to divide the chromo- somes may be made visible using a dye that appears blue when bound to the DNA Figure 1.
