2017年4月27日 · The chloroplast, found only in algal and plant cells, is a cell organelle that produces energy through photosynthesis. The word chloroplast comes from the Greek words khloros, meaning “green”, and plastes, meaning “formed”.

2024年12月20日 · chloroplast, structure within the cells of plants and green algae that is the site of photosynthesis, the process by which light energy is converted to chemical energy, resulting in the production of oxygen and energy-rich organic compounds.

2024年4月8日 · Chloroplasts are membrane-bound organelles within plant and algal cells responsible for photosynthesis, converting sunlight into energy while releasing oxygen from water. The precise location of chloroplasts within plant cells is a …

2024年1月29日 · A chloroplast is a type of organelle known as a plastid, predominantly found in plant cells and algae. It is the site of photosynthesis, a process where light energy is converted into chemical energy , fueling the organism’s activities.

2020年7月15日 · The chloroplast is a type of cell organelle called plastids found in plants and blue-green algae. It contains the pigment chlorophyll that traps the light energy of the sun to convert them to the chemical energy of food by a process called photosynthesis .

2023年6月9日 · Photosynthesis is not magical, however — it's just the cool chemical handiwork of these little cellular structures called chloroplasts, a type of organelle found only in plants and eukaryotic algae (eukaryotic means possessing a clearly defined nucleus) that captures sunlight and converts that energy into food for the plant.

2023年11月1日 · Chloroplasts are membrane-bound plastids that contain a network of membranes embedded into a liquid matrix and harbor the photosynthetic pigment called chlorophyll. It is this pigment that imparts a green color to plant parts and serves to capture light energy. Chloroplasts can be found in the cells of the mesophyll in plant leaves.

2024年5月28日 · Chloroplasts carry out the process of photosynthesis. Their main role is to provide the site for light and dark reactions. It is where inorganic sources, water, and light energy are converted into food, i.e. glucose (a sugar molecule).

2024年2月26日 · The Takeaway: Chloroplasts are organelles found in plant cells and some algae. These tiny green structures play a vital role in the energy conversion process that sustains life on Earth.

2025年1月22日 · Chloroplasts (see Figure \(\PageIndex{41}\)) are disk-shaped structures ranging from 5 to 10 micrometers in length. Like mitochondria, chloroplasts are surrounded by an inner and an outer membrane.The inner membrane encloses a fluid-filled region called the stroma that contains enzymes for the light-independent reactions of photosynthesis.
