Sourced from [twinkl.com] titled “What is a Chloroplast?” Chloroplasts are mostly oval-shaped blobs, but they can come in shapes like stars and ribbons too. A chloroplast is protected by a smooth outer membrane which holds all of its material. They contain chlorophyll, which is the pigment that gives plants their green colour. Chloroplasts are important to the growth of the plant because they turn sunlight into energy for the plant to use. This is a process called photosynthesis. Chloroplasts are multi-talented. They also store energy for the plant cell and fight off diseases. They are an important part of the cell’s immune system which helps it to stay healthy. Just l...

Click on PDF to download from Part 3 2023: Researchers reported a production method for spider silk fibers from gene-edited transgenic silkworms for a sustainable alternative material six times stronger than Kevlar. This type of fiber could be utilized as surgical sutures, addressing a global demand exceeding 300 million procedures annually. The spider silk fibers could also be used to create more comfortable garments and innovative types of bulletproof vests, said Mi, and they may have applications in smart materials, the military, aerospace technology, and biomedical engineering. To spin spider silk from silkworms, Mi and his team introduced spider silk protein genes into the DNA of silkworms so that it would be expressed in their glands using a combination of CRISPR-Cas9 gene editing technology and hundreds of thousands of microinjections into fertilized silkworm eggs.
