Photosynthesis Worksheets made by Liesl at homeschoolden.com Feel free to make as many copies as you need for your kids or students. You may not share this file or upload this file onto any file sharing website. Thank you! I hope you find these useful! ~Liesl What are the parts of the plant? Draw a picture of a plant cell. What is cellulose? What is the vacuole? What are chloroplasts? What is photosynthesis? Where does it take place inside the plant cell? Made by Liesl at homeschoolden.com What ingredients do chloroplasts need to make food? Using a molecular model set, make the two molecules you wrote down above. If you don't have a set, draw a picture of these two molecules: What is the name of the "food" that plants make? How many carbon atoms are there? How many hydrogen atoms are there? How many oxygen atoms are there? Make a model of this molecule using a molecular model set (if you have one). What are the products of photosynthesis? How does water go from the roots to the top of a tree? How are sugars moved from the leaves to all of the cells in the plant and to the roots? Made by Liesl at homeschoolden.com Water Carbon Dioxide Oxygen is known as ________ and has ____________ bond/s. Carbon is known as ________ and has ____________ bond/s. Hydrogen is known as ________ and has ____________ bond/s. Water is also known as: Create a water molecule: Carbon dioxide is also known as: Create a carbon dioxide molecule: Made by Liesl at homeschoolden.com What are the parts of the plant? Terminal bud, stem, leaves, roots, root hairs, fruit (and/or flower) Draw a picture of a plant cell. Answers can contain any of the following: What is cellulose? The main component of plant cell walls that gives plants their strength What is the vacuole? These are like storage containers in plant cells for food, water and nutrients What are chloroplasts? This is where plants make food What is photosynthesis? Where does it take place inside the plant cell? This is the process of chloroplasts making food using sunlight energy. What ingredients do chloroplasts need to make food? carbon dioxide (CO2) and water (H2O). Made by Liesl at homeschoolden.com What is the name of the "food" that plants make? glucose How many carbon atoms are there? 6 How many hydrogen atoms are there? 12 How many oxygen atoms are there? 6 Make a model of this molecule using a molecular model set (if you have one). Since we are not studying chemistry at the moment, we quickly reviewed some chemistry basics and went over the chemical bonding again with this explanation of happy atoms over at: http://www.chem4kids.com/files/atom_bonds.html Water molecule Carbon Dioxide molecule What are the products of photosynthesis? Glucose and oxygen How does water go from the roots to the top of a tree? Water moves through xylem How are sugars moved from the leaves to all of the cells in the plant and to the roots? Sugars move through phloem. Oxygen is known as O and has 2 bond/s. Carbon is known as C and has 4 bond/s. Hydrogen is known as H and has 1 bond/s. Here are the activities we did to show how the molecules from carbon dioxide Made by Liesl at homeschoolden.com and water form the basis for glucose and oxygen molecules: We used the Molymod Organic Chemistry Model Kit.
