Crops that have been genetically altered to produce proteins from the soil bacterium Bacillus thuringiensis are referred to as Bt. crops (also known as Bt. transgenic crops) (Bt.). Toxic to some insect species, these proteins act as a natural pesticide. Bt corn, which has been altered to produce the Bt protein Cry1Ab, is one example of a Bt crop.
Angiosperms: Salient Features
1. They occur in ultimate environments on the earth
2. They are covered seed-bearing plants
3. Herbs, Shrubs, Trees, Twiners, Trailers, and Climbers among others make up the sporophytic plant body
4. The Gametophytic phase is highly contracted and only represented by a few cells. The free-living existence of gametophytes is absent
5. vascular tissue is well developed, xylem and phloem are present. The xylem contains tube-like structures that are vessels, tracheids, xylem parenchyma, and xylem fibers. Phloem contains a tube that is a sieve tube, companion cells, Phloem parenchyma, and Phloem fibers
