What are chloroplasts and what are they made of?

Answer 1

Chlorophyll is a pigment that is present in plants. It gives plants its green color and is used in photosynthesis. Chlorophyll is made when a plants absorbs energy from the sun and elements such as water and carbon dioxide are exchanged with oxygen and glucose.

Answer 2

Chloroplasts are organelles found in plant cells responsible for photosynthesis, converting light energy into chemical energy. They are composed of a double membrane, thylakoid membranes where photosynthesis occurs, stroma where enzymes are found, and contain their own DNA and ribosomes.

Answer 3

Chloroplasts contain chlorophyll and absorbs light energy for photosynthesis. Chloroplasts are made of three types of membrane;

1. A smooth outer membrane which is freely permeable to molecules.
2. A smooth inner membrane which contains many transporters: intergral membrane proteins that regulate the passage in an out of the chloroplast of

• small molecules like sugars
• proteins synthesized in the cytoplasm of the cell but used within the chloroplast

3. A system of thylakoid membranes

Answer 4

Chlorophyll is a chlorin pigment, which is structurally similar to and produced through the same metabolic pathway as other porphyrin pigments such as heme. At the center of the chlorin ring is a magnesium ion. For the structures depicted in this article, some of the ligands attached to the Mg2+ center are omitted for clarity. The chlorin ring can have several different side chains, usually including a long phytol chain. There are a few different forms that occur naturally, but the most widely distributed form in terrestrial plants is chlorophyll a. The general structure of chlorophyll a was elucidated by Hans Fischer in 1940, and by 1960, when most of the stereochemistry of chlorophyll a was known, Robert Burns Woodward published a total synthesis of the molecule as then known.[6] In 1967, the last remaining stereochemical elucidation was completed by Ian Fleming,[7] and in 1990 Woodward and co-authors published an updated synthesis.[8]

Answer 5

It is made up of organelles in the plant cell called "chloroplasts". The purpose of the chloroplast is to make sugars and starches. They use a process called '''photosynthesis to get the job done. Photosynthesis is the process of a plant taking energy from the Sun and creating sugars. When the energy from the Sun hits a chloroplast, chlorophyll uses that energy to combine carbon dioxide (CO2) and water (H2O). The molecular reactions create sugar and oxygen (O2). Plants and animals then use the sugars (glucose) for food and energy.'''

Answer 6

Specialised organelles within plant cells known as chloroplasts.

Answer 7

Chloroplasts are made of thylakoids, stroma, and double membranes. Chlorophyll is made of the sun's energy and mostly made of magnesium.

Answer 8

No. Chlorophyll is an organelle/ pigment found inside plant cells.

Answer 9

no - chlorophyll is in the chloroplast

Chlorophyll= a pigment that is stored in chloroplasts

Answer 10

a plastid in green plant cells which contains chlorophyll and in which photosynthesis takes place. Plastids manufacture and store important chemicals used in plant cells
