Photosynthesis- Ideas for Teaching, Resources for Lesson Plans, and Activities for Unit Planning
They start out as tiny seeds ( curled up in a ball) Then they germinate (start growing into a plant) It rains (use hands) The sun shines (Hold arms out like sunbathing) The plant uses the "chlorophil" in it's body to make food and grow (get bigger) As I said, I think that there is probably more to it, but you get the idea. I use a chemical equation: water and carbon dioxide in the presence of chlorphill and sunlight yields oxygen and glucose I always teach photosynthesis and respiration together so we can discuss how they are opposite processes
The cyclical nature of the two processes can be constructed visually, and the photosynthesis and respiration equations can be balanced in a descriptive and numerical format
PICTURE endosymbiosis Theory that attempts to explain the origin of the DNA-containing mitochondria and chloroplasts in early eukaryotes by the engulfing of various types of bacteria that were not digested but became permanent additions to the ancestral "eukaryote". epithelial tissue Cells in animals that are closely packed in either single or multiple layers, and which cover both internal and external surfaces of the animal body

The electrons and hydrogen ions are used, and some of the oxygen may get used for respiration, but a lot of them just go back out to the atmosphere where you and I may breath them with our very own gas exchange systems. One of the hard to understand aspects of light, is that it appears to travel as either a wave or a particle depending on how you happen to be looking at it
Autumn Leaves and Fall Colors - Why do autumn leaves change color?
Did you ever wonder how and why a fall leaf changes color? Why a maple leaf turns bright red? Where do the yellows and oranges come from? Table of Contents Why Do Leaves Change Color? Photosynthesis Autumn Preparations for Winter Learn More: Surviving Winter Easy Reading Projects To answer those questions, we first have to understand what leaves are and what they do
What Is the Function of Chlorophyll? Chlorophyll is the green pigment inside of the leaves of plants that captures sunlight, and its function is to pass down excited... Other People Are Reading What Is the Function of Chlorophyll in Plant Cells? What Happens When a Chlorophyll Molecule Absorbs Light? Features You can find chlorophyll inside cellular structures called chloroplasts, the tiny pill-shaped organelles responsible for photosynthesis
Photosynthesis produces oxygen that escapes the plant via stomata, which are openings in the leaves that the plant opens and closes to regulate levels of gas and water
A series of metabolic pathways (the Krebs cycle and others) in the mitochondria result in the further breaking of chemical bonds and the liberation of ATP. Immediately after exposure to 14CO2, the plant's photosynthetic tissue is killed by immersing it in boiling alcohol, and all of the biochemical reactions cease
It contains enzymes and produces and digests lipids (fats) and membrane proteins; smooth ER buds off from rough ER, moving the newly-made proteins and lipids to the Golgi body and membranes stroma - part of the chloroplasts in plant cells, located within the inner membrane of chloroplasts, between the grana. Rough ER transport materials through the cell and produces proteins in sacks called cisternae (which are sent to the Golgi body, or inserted into the cell membrane)
PHOTOSYNTHESIS
Biologists see the same principles in operation! This food produced by plants is the same sort of food which we might eat (carbohydrates, fats, proteins, etc.). PHOTOSYNTHESIS - the most important process on earth? It is important to get the process of photosynthesis into perspective, especially in relation to the processes covered in previous topics: respiration, and digestion in animals
Artificial photosynthesis to make plants green with envy
Advanced composites may borrow designs from deep-sea shrimp July 14, 2015 New research is revealing details about how the exoskeleton of a certain type of deep-sea shrimp allows the animal to survive scalding hot waters in hydrothermal vents thousands of feet under water. Imaging glucose uptake activity inside single cells July 17, 2015 Researchers at Columbia University have reported a new approach to visualize glucose uptake activity in single living cells by light microscopy with minimum disturbance
PRICKLY PEAR CACTUSPrickly pear cacti (genus Opuntia, many species) are North American desert succulents that have flat, fleshy, leaf-shaped pads and large spines (modified leaves) growing from tubercles (small bumps on the pads). PLEISTOCENEThe Pleistocene was an epoch of geologic time that lasted from 1.8 million to 11,000 years ago; it was a period of widespread glaciation and large Ice Age animals (caled Pleistocene Megafauna)
Rarely, certain plants, especially those that live in the desert, store carbon dioxide or other necessary components of photosynthesis in other compartments within the plant structure. However, a plant actually uses a number of specialized structures that conduct the chemical reactions necessary to transform energy from sunlight into energy molecules that the plant can use
Photosynthesis
In the daytime, when the light reaction is occurring and ATP is available (but the stomates must remain closed), they take the CO2 from these organic compounds and put it into the Calvin cycle. Chlorophyll and several other pigments such as beta-carotene are organized in clusters in the thylakoid membrane and are involved in the light reaction
