Sundew: The Sticky Plant With A Killer Instinct
- Members of the genus drosera
- 200 species, do not live in Antarctica
- Primarily found in Australia and Africa
- It takes 15 minutes to kill its prey
- Adaptation for life and nutrient-poor soil
- Consumes proteins and converts them into nitrogen
- Roots are only great for water uptake
- Commonly found in swampy area
- Tentacles fold in the direction of prey
- It’s suspected that the movement is caused by chain reactions inside the cells to
make them more acidic and make the cell walls more flexible, which causes cells
to expand.
- Leaves are used as an expectorant and aphrodisiac and to treat coughs and
ulcer
- PINK SUNDEWS > flat leaves, most common, easy to escape
- THREAD-LEAVED SUNDEWS > have thin, tube-like leaves that unfurl as they
grow
- COMMON SUNDEW > found in northern latitudes, spherical leaves
- CAPE SUNDEW > leaves fold at the same time with tentacles
- LEAVED SUNDEWS > good for beginners, one of the hardiest drosera
- DROSERA ANDROMEDA > does not move at all when feed
>>Two types of glands in tentacles
1. The first type secretes the sweet sticky nectar that attracts and snares
insects.
2. The second type makes the digestive juices to break down its prey’s soft
tissue.
