Photosynthesis is process by which green plants and certain other organisms use the energy of light to convert carbon dioxide and water into the simple sugar glucose. In so doing‚ photosynthesis provides the basic energy source for virtually all organisms. An extremely important byproduct of photosynthesis is oxygen‚ on which most organisms depend. Photosynthesis occurs in green plants‚ seaweeds‚ algae‚ and certain bacteria. These organisms are veritable sugar factories‚ producing millions of

ANIMAL CELL PROJECT By: Jonathan Everett Science 2nd Ms. Thompson January 11‚ 2013 Have you ever heard of an animal cell? Well‚ I you haven’t it is a cell that is found in an animal that consist of multiple organelles. Each organelle has a special job that helps the cell function. This paper will help describe each organelle in the animal cell. 1. Endoplasmic Reticulum The Endoplasmic Reticulum is found in both the plant and animal

Introduction: On this Earth‚ every living species needs energy to live. Energy is a product of photosynthesis‚ which is the process that converts energy in sunlight to chemical forms of energy that can be used by biological systems2. Many organisms are not able to use the energy obtained from sunlight directly; however‚ plants are able to use this energy and convert it into chemical energy by converting CO2 (carbon dioxide) and H2O (water) to organic materials3. The energy source for photosynthesis

fixing carbon dioxide into carbohydrates occurs in the light independent process. a) light dependent; b) light independent; c) ATP synthesis; d) carbon photophosphorylation; e) glycolysis • 5. Carbon dioxide enters the leaf through stamata . a) chloroplasts; b) stomata: c) cuticle; d) mesophyll cells; e) leaf veins • 6. The cellular transport process by which carbon dioxide enters a leaf (and by which water vapor and oxygen exit) is diffusion . a) osmosis; b) active transport; c. co- transport; d)

Photosynthesis Chapter Outline CHAPTER OUTLINE Photosynthetic organisms are autotrophs. What is light? Pigments absorb light‚ which drives photosynthesis. Photosynthesis requires both photochemical and biochemical reactions to produce sugars. Chloroplasts are the site of photosynthesis in plants. The light reactions of photosynthesis produce ATP. The light reactions of photosynthesis also produce NADPH. Perspective 10.1 The Evolution of the Light Reactions The biochemical reactions convert

The Nucleus: In the kingdom the nucleus is the king. The nucleus is a membrane-bound organelle found in the center of the cell that contains all of the genetic information‚ and DNA and controls the rest of the cell. To the kingdom the nucleus is the king because of how he controls the kingdom and is responsible for the wealth of the town through his actions. Additionally not all cells have a nucleus. Just as not all kingdoms have a king. The Nuclear Envelope: The nuclear envelope is similar to

if light and healthy pigments were necessary for the occurrence of the photosynthesis. Different tubes were used‚ some containing healthy chloroplasts‚ and other containing unhealthy chloroplasts. They were exposed to light or hidden from it‚ by being wrapped with foil. The results showed that the tube which was exposed to light and containing healthy chloroplasts had the higher rate of photosynthesis.

place inside the cells. In contrast‚ The site of photosynthesis is chloroplast‚ while the sites of cellular respiration are cytoplasm and mitochondrion. The chloroplast‚ which has two membranes around a central aqueous space‚ is found mainly in mesophyll cells forming the tissues in the interior of the leaf. The chloroplast is made of grana‚ thylakoid‚ and stroma. Chlorophyll‚ which is a green pigment‚ is located in the chloroplasts. The mitochondrion also has two membranes‚ the outer membrane and
