Which of the following features is unique to angiosperms?
In angiosperms, double fertilization which is a unique angiosperm feature (first discovered by Nawaschin in 1898 in Fritillaria and Lilium) occurs when one male gamete fuses with the egg cell to produce diploid zygote while the other male gamete fuses with diploid secondary nucleus (formed by fusion of two polar nuclei …
Why angiosperms are most successful terrestrial plants?
And that would have given the angiosperms the energy to push competitors like conifers out of the canopy around 150 million years ago, making angiosperms the most productive group of land plants in the world. Flowers play a role in the diversification, the team says, but leaf veins help these plants become so abundant.
What reproductive feature was unique for angiosperms compared to other plants?
We’ll look more closely at reproduction in angiosperms, which are unique among plants for three defining features: they have flowers, they have fruit-covered seeds, and they reproduce via a process called double fertilization.
What do plants do in the dark?
Plants take in oxygen in the dark as they require it to respire (breathe) and as a part of their metabolism. During the day they require less oxygen due to photosynthesis but in darkness, this process no longer happens so they take in more oxygen .
Do plants grow better in light or dark?
ANSWER: In a strict sense, plants do not grow faster in the dark; they grow slower. However, plants seem to grow faster in insufficient light due to rapid cell elongation. In other words, they don’t grow faster, they simply stretch.
Can snake plants live in low light?
Snake Plants (Sansevieria trifasciata) The Sansevieria species are some of the best low-light plants. The optimal place to keep this relatively inexpensive and low-maintenance plant is the bedroom because it converts carbon dioxide into oxygen at night. This is a very long-lived plant that can thrive for decades.
