Question

Differents between chromoplast and chloroplast

​

Answer 1

Chloroplast are cell organelles which undergo photosynthesis and Chromoplast are organelles which Bio-synthesize and store pigments in the plant cells.

Explanation:

Chloroplast and Chromoplast are cell organelles of a plant cell. They are two types of colored plastids among plants.

• Chloroplast

It is the green pigmented cell organelle which undergoes photosynthesis to produce energy in plants. It contains chlorophyll (the pigments responsible for photosynthesis within the chloroplast) and other carotenoids. These are found in the leaves of the plant. They have a lamellar system present in them.

• Chromoplast

They are pigmented organelles, they are typically found in yellow, orange or red pigments. It contains only carotenoids. They are plastids which function in bio-synthesize and storage of pigments. These are found in the petals of flowers, ageing leaves and ripening fruits of a plant. These lack a lamellar system.

Answer 2

Chromoplast

• Plants also have chromoplast, which is a colourful pigment.
• It is a heterogeneous organelle that is primarily involved in the production and storage of pigments other than chlorophylls.
• Chromoplasts create carotenoids, which are pigments.
• Carotene and xanthophyll are the two most common carotenoids.
• The orange hue comes from carotene, while the yellow colour comes from xanthophyll.
• In addition, chromoplasts may be found in the plant's coloured sections, such as the flower, fruit, and aged leaves.
• The roots of carrots and sweet potatoes contain chromoplasts as well.
• Furthermore, chloroplasts in ripening, aged, or stressed regions of plants undergo a tremendous increase in the accumulation of carotenoid pigments, transforming them into chromoplasts.
• The primary purpose of chromoplasts in flowers and fruits is to attract animals with colour.
• Pollination, fertilisation, and fruit dissemination are all facilitated as a result.

Chloroplast

• Plants and certain photosynthetic algae have chloroplasts. It's surrounded by two membranes.
• The fluid inside this compartment is known as Stroma.
• Thylakoids also refer to the stroma's free-floating, flattened, small membrane vesicles.
• Grana are the granular units that they produce. Chlorophylls are the most common photosynthetic pigment found in chloroplasts, and they give the plastid its green hue.
• Chlorophylls also construct photosystems on the thylakoid membrane to capture energy from the sun.
• During photosynthesis, this energy is stored in energy molecules like as ATP and NADPH.
• Additionally, during the dark reaction of photosynthesis, these molecules are employed to produce glucose by mixing carbon dioxide and water.
• Although photosynthesis is their primary role, chloroplasts also perform fatty acid synthesis, amino acid synthesis, and immunological function in plants.
