Chloroplasts are a type of plastid that are distinguished by their green color, the result of specialized chlorophyll pigments. In plants, chloroplasts occur in all green tissues.
Intro to photosynthesis (article)
The ecological importance of photosynthesis Photosynthetic organisms, including plants, algae, and some bacteria, play a key ecological role. They introduce chemical energy and fixed carbon into ecosystems by using light to synthesize sugars.
Photosynthesis, Chloroplast | Learn Science at Scitable Photosynthetic Cells Cells get nutrients from their environment, but where do those nutrients come from? Virtually all organic material.
Chloroplasts and Photosynthesis
Show details Chloroplasts and Photosynthesis All animals and most microorganisms rely on the continual uptake of large amounts of organic compounds from their environment. These compounds are used to provide both the carbon skeletons for biosynthesis and the metabolic energy that drives cellular processes.
Chlorophyll and Chloroplasts
Image by John Fowler. Plants have different types of pigments besides chlorophyll. Some of them also assist in absorbing light energy. These different pigments are most noticeable during the fall. During that time, plants make less chlorophyll and the other colors are no longer hidden beneath green.
Light and photosynthetic pigments
This process begins with the absorption of light by specialized organic molecules, called pigments, that are found in the chloroplasts of plant cells. Here, we’ll consider light as a form of energy, and we’ll also see how pigments – such as the chlorophylls that make plants green – absorb that energy. What is light energy?
Chloroplast Function in Photosynthesis
A chloroplast contains a green pigment called chlorophyll, which absorbs light energy for photosynthesis. Hence, the name chloroplast indicates that these structures are chlorophyll-containing plastids.
What is a chloroplast?
A chloroplast is an organelle within the cells of plants and certain algae that is the site of photosynthesis, which is the process by which energy from the Sun is converted into chemical energy for growth. A chloroplast is a type of plastid (a saclike organelle with a double membrane) that contains chlorophyll to absorb light energy.
Lesson Explainer: Structure of the Chloroplast
Definition: Cellular Respiration Cellular respiration is a process in living organisms through which carbon-containing compounds (such as glucose) are broken down to release energy in the form of ATP. Figure 2 shows a basic outline of the major organelles contained within a plant cell. A chloroplast is highlighted.
Photosynthesis and plants
Photosynthesis is an endothermic process that takes part in the chloroplasts (found in leaf cells). Within chloroplasts is chlorophyll, a green pigment responsible for trapping light energy in.
