How is energy transformed in plant cells? Plant cells obtain energy through a process called photosynthesis. This process uses solar energy to convert carbon dioxide and water into energy in the form of carbohydrates. It is a two-part process. Plants, algae and some bacteria use photosynthesis to create energy used for growth, maintenance and reproduction. […]

Abiotic factors include water, sunlight, oxygen, soil and temperature. Water (H2O) is a very important abiotic factor – it is often said that “water is life.” All living […]
Which of the following elements are magnetic?
Which of the following elements are magnetic? Iron, cobalt, and nickel are the only three naturally occurring elements that are magnetic. These are the elements that magnets are made from. Iron magnets tend to lose their magnetic properties over time and with increased temperature. Nickel and cobalt do not lose their magnetism. What are 3 […]
Who gave corpuscular theory of light?
Who gave corpuscular theory of light? Newton Who discovered light as a particle? Sir Isaac Newton How does light act as a particle? Light behaves mainly like a wave but it can also be considered to consist of tiny packages of energy called photons. Photons carry a fixed amount of energy but have no mass. […]
Is charge a vector quantity?
Is charge a vector quantity? 1 Answer. Nothing is a vector until defined with a direction. Electric charge is a scalar quantity because charge never graduated into the level of vectors or tensors that need both magnitude and direction. Is electricity a vector quantity? Vector of scalar? As power doesn’t have any direction, it is […]
