19 Chloroplast Facts for Kids
- Chloroplast is a plastid organelle found in certain plant and algae cells.
- One of the main functions of chloroplasts is to conduct the photosynthesis process.
- Chloroplast contains chlorophyll, which is used to capture radiant energy from sunlight.
- Plants get their green color from the chlorophyll in chloroplasts.
- The radiant energy captured by chlorophyll is what powers photosynthesis in a chloroplast.
- The waste byproduct of the photosynthesis process is oxygen, the most important element to all living organisms.
- A plant cells that contains chloroplast is a chlorenchyma cell.
- One chlorenchyma cell can have between 1 and 100 chloroplasts.
- In plants, chloroplasts are highly concentrated in the leaves.
- The shape of a chloroplast can vary among plant and algae species.
- Terrestrial plants typically have a lens-shape chloroplast.
- Algae can have a wide range of chloroplast shapes.
- The diameter of a chloroplast varies between 0.001 and 0.01 millimeter.
- The thickness of a chloroplast varies between 0.001 and 0.003 millimeter.
- Chloroplast has its own DNA called plastome, which can be abbreviated as cpDNA or ctDNA.
- It’s estimated that almost all chloroplasts can be traced back to a single endosymbiotic event that happened between one and two billion years ago. Where a eukaryote either ate or was infected by a cyanobacterium. The mutual benefit between the eukaryote and the cyanobacterium paved the evolutionary path for plants as we know them today.
- In 1873, German botanist Hugo von Mohl was the first person to describe a chloroplast.
- In 1884, Polish-German botanist Eduard Strasburger coined the term chloroplast.
- The term chloroplast comes from two Greek words, chloros and plastes. Chloros in Greek means “green”, while plastes in Greek means “one who forms”.
