Chapter 01 - Exploring Life Cells are an organism’s basic unit of structure and function. The cell is the lowest level of structure that is capable of performing all the activities of life. For example, the ability of cells to divide is the basis of all reproduction and the basis of growth and repair of multicellular organisms.

The Structures of Life Proteins are worker molecules that are necessary for virtually every activity in your body. They circulate in your blood, seep from your tissues, and grow in long strands out of your head. Proteins are also the key components of biological materials ranging from silk fibers to elk antlers.

- Every cell in your body contains organelles (structures that have specific functions). Just like organs in the body, each organelle contributes in its own way to helping the cell function well as a whole. The nucleus, mitochondria and chloroplasts are all organelles.

Lysosome Structure The human body comprises of about 50 to 75 trillion cells. The cell is the smallest unit of life and is often called the building block of life. A single cell is made up of many different organelles, that have specific functions, such as the nucleus, Golgi bodies, mitochondria, peroxisomes and lysosomes.ysosome Structure. Lysosomes are actually membranous sacs filled with enzymes. They are found in all eukaryotic cells and act as 'garbage disposal' or the 'digester' of the cell.

Maintaining Life: Necessary Life Functions Like all complex animals, humans must maintain a core set of necessary life functions to survive. These include maintaining boundaries, movement, responsiveness, digestion, metabolism, excretion, reproduction, and grow.In order to survive, humans also need nutrients, oxygen, water and an appropriate atmosphere.ithout these features, humans wouldn’t be able to perform necessary life functions to survive. Responsiveness. Responsiveness is defined as the ability to sense changes in the environment and then respond to them (also called excitability). Responsiveness is an extremely important necessary life function.

Human skeletal system Protection of the heart, lungs, and other organs and structures in the chest creates a problem somewhat different from that of the central nervous system. These organs, the function of which involves motion, expansion, and contraction, must have a flexible and elastic protective covering.

The Cardiovascular System: Mechanics and Dynamics Explain that cells take in nutrients in order to grow, divide and to make needed materials. S7L2a b. Relate cell structures (cell membrane, nucleus, cytoplasm, chloroplasts, and mitochondria) to basic cell functions. S7L2b 1. Cells are the smallest single unit that can maintain life. Within each cell are a collection of organelles that perform specific functions.

5. The human skeleton is wonderfully made in such a way, that it can support the body in the erect position and enable the body to move freely. Structure and Functions of the Skeleton The skeleton is composed of 206 separate bones in the adult, and the cartilages and ligaments, which help to unite the bones at the joints.

How Many Organs Are in the Human Body The body's functions are conducted by organs. Each organ is a recognizable structure (for example, the heart, lungs, liver, eyes, and stomach) that performs specific functions. An organ is made of several types of tissue and therefore several types of cells (see Cells). For example, the heart (see Heart) contains muscle tissue that contracts to pump blood, fibrous tissue that makes up the heart valves, and special cells that maintain the rate and rhythm of heartbeats.

Competency 046: Structure and Function of Living Things How Structure Complements Function in Tissues, Organs, Organ Systems, and Organisms. The beginning teacher analyzes how structure complements function in tissues, organs, organ systems, and organisms. The cell is the basic unit of all forms of life. However, there are several levels of cell organization within many multicellular organisms. Cells are arranged in hierarchical levels of organization.

What are vestigial structures? give an example? Vestigial structures are different parts in an organisms body that are no longer necessary for their survival, but were necessary for their ancestors. An example of a vestigial structure would be the small leg bones found deep within the body of some whales. Although whales no longer need legs for support, as they live in the oceans, their ancestors did have legs.

Human body Plant and Animal Parts: Students learn that all living things have basic needs, and they meet those needs in various ways. Just as humans have external body parts that perform different functions to meet their needs, animals and plants also have body parts that perform different functions to meet their needs. A magnifier is a tool that reveals further details of plant and animal parts that are not easily seen with the unaided eye.

Life Support System These people have one or more failing organs or organ systems, and would not be able to survive without assistance. The organs and organ systems that often fail and require life support are breathing (respiratory system); heart and blood pressure (cardiovascular system); kidney (renal system); and intestines (gastrointestinal system).
