Photosynthesis

Answer Key:

All organisms use energy to carry out their life functions. Some organisms obtain this energy from sunlight. The process by which this energy transfer takes place is called photosynthesis. Photosynthesis involves a biochemical pathway in which the product of one reaction is consumed in the next reaction. Autotrophs are organisms that carry on photosynthesis and includes plants and other organisms containing the green pigment chlorophyll. Autotrophs use carbon dioxide and water to make oxygen and the simple sugar glucose. The pigment chlorophyll absorbs light energy from the sun during the light reactions. Accessory pigments also in the chloroplast absorb other wavelengths of light that chlorophyll does not absorb. These accessory pigments are responsible for other colors we see in plants such as red, orange, and yellow. Chloroplasts are surrounded by a double membrane. Inside chloroplasts is a system of membranes arranged as stacks of flattened sacs called granum. Each sac in the stack is called a thylakoid. The thylakoids are surrounded by a solution called the stroma. The dark reactions of photosynthesis take place in the stroma. Most chloroplasts are found in the leaves of plants. The underside of a leaf contains openings called stomata where gases such as oxygen and carbon dioxide enter and leave. These openings or stomata are closed during the hottest times of the day by cells called guard cells.

Name:

Evolution

True/False Indicate whether the sentence or statement is true or false.
	1.	The theory of evolution states that species change over time.
	2.	The inheritance of acquired characteristics was one mechanism of evolution supported by Darwin.
	3.	Darwin observed that the plants and animals of the Galapagos Islands were the same as those on islands off the coast of Africa with similar environments.
	4.	The book Principles of Geology by Charles Lyell described how changes in land formations can cause species to evolve.
	5.	In his “Essay on the Principle of Population,” Malthus said humans were the only population that could continue to grow in size indefinitely.
	6.	The two major ideas that Darwin presented in The Origin of Species were that evolution occurred and that natural selection was its mechanism.
	7.	The environment dictates only the direction and extent of evolution.
	8.	The environment selects which organisms will survive and reproduce by presenting challenges that only individuals with particular traits can meet.
	9.	The way an embryo develops is not important in determining the evolutionary history of a species.
	10.	Within populations, divergence leads to new species.
