they can source water whereas fungi can live almost anywhere so long as it has other small organisms nearby. Plants make their own food‚ using water and carbon dioxide to make glucose (energy) and oxygen (a waste product) in a process called photosynthesis. Though very little of it‚ it also lets out some carbon dioxide. This is the reason that it has adapted to live in places with lots of sunlight- so it can absorbed enough of it to make energy. It also grows in ground that has a water source. Different

Gabriela Rios-Martinez March 1‚ 2014 BIO 141 Exam 1 Study Questions Chapter 1: Biology and the Tree of Life (#1 – 4) 1. What is the difference between a hypothesis and a scientific Theory? Between a hypothesis and a prediction? What kinds of hypotheses are useful for scientific investigations that try to explain the natural world‚ and which are not? Give one or more examples of hypotheses that are and are not scientifically useful. (a.) A scientific theory has two components; a pattern

Below are a list of concepts and ideas you need to know for the first Bio 100/107 Test Chapter 1: What is the organizational hierarchy? What is each level? What are emergent properties? At what level does life emerge? Organisms interact with the environment: energy and atoms Unity explains that cells have several common features. What are those features? What is diversity? How does Evolution mediated by Natural Selection explain Unity and Diversity? Chapter 2: Life is composed of atoms

are the basis of all life on Earth. They create sugars‚ and the oxygen that we breathe. This process is also known as chloroplast. The mitochondria work in the opposite direction and breaks down the sugars and nutrients that the cell receives. Photosynthesis is the process of a plant taking energy from the Sun and creating sugars. When the energy from the Sun hits a chloroplast‚ chlorophyll uses that energy to combine carbon dioxide and water. The molecular reactions create sugar and oxygen. Plants

Problem: Why do leaves change color in the fall? Background: Leaves contain many pigments such as chlorophyll b‚ xanthophyll‚ and beta carotene besides chlorophyll a. They are part of the photosystem in the thylakoids. Pigment molecules can be separated by a procedure called chromatography. The procedure uses a special paper and solvent. The chlorophyll molecules adhere to the paper. The solvent molecules move up the paper by capillary action. Each chlorophyll molecule will travel up the paper at

this process‚ also known as photosynthesis to happen it involves three different pigments that give the leaves their color. Trees are autotrophs; this means that they make their own food. The leaves obtain water through their roots‚ but also they need sunlight‚ carbon dioxide‚ and chlorophyll. Chlorophyll is the pigment that gives leaves their green color and makes photosynthesis happen. Without photosynthesis or chlorophyll the leaves would stay the same‚ Photosynthesis (which means putting together

organisms need to survive. Carbon is the basic building block of all living things. It moves through an ecosystem in a cycle called the carbon cycle. In this cycle carbon in the atmosphere is known as carbon dioxide. Plants use it to perform photosynthesis and make food. Animals then eat the plants that contained the carbon. Carnivores then eat the other animals thus releasing carbon in animals. Both plants and animals respire. Carbon dioxide is returned to the atmosphere through respiration and

the structures are called stomata.[1] Leaf transpiration occurs through stomata‚ and can be as a necessary "cost" associated with many processes such as the opening of the pistil and allowing the diffusion of carbon dioxide gas from the air for photosynthesis. Transpiration also cools plants and enables mass flow of mineral nutrients and water from roots to shoots. Water is absorbed at the roots by osmosis‚ and any dissolved mineral nutrients travel with it through the xylem. The rate of transpiration
