Question

Tallest angiosperm is
(a)Eucalyptus
(b)Redwood tree
(c)Oaktree
(d)Pinus

Answer 1

Hint: The needles grow short and narrow, which look like the needles of cedar or juniper. These leaves make their introduction growing out of the bark of the upper branches. The scale-like upper leaves are compatible with the warmer, drier conditions found within the forest canopy.

Complete answer:
Angiosperms are a group of flowering plants which have various salient features. The tallest angiosperm is Eucalyptus(Eucalyptus regnans).

Additional Information:
 Eucalyptus tree-The tallest angiosperm:
-It is the tallest blooming plant and perhaps the tallest tree on the planet.
-The vast majority of these trees are quick cultivators, arriving at statutes of around 30 to 180 feet or more, contingent upon the assortment, with roughly 60 per cent of their development.
-When devoured in the limited quantities found in nourishments.
-Indications of eucalyptus harming may incorporate stomach agony and consumption, discombobulation, muscle shortcoming, little eye students, sentiments of suffocation, and some others.

Salient features of Angiosperms are;
-The embryo sac (Ovule) remains enclosed within the ovary.
- plant part helps in fertilization, so water isn't essential for fertilization.
- Double fertilization is present. The endosperm is triploid.
-Flowers are produced rather than a cone.
-They are of two types namely monocotyledons and dicotyledons (named based on the number of cotyledons present in them).
-The endosperm is the nutrient-rich which feeds the embryo.
-Seed, flower and fruit formation occurs.

So, the correct answer is,” Eucalyptus”.

Note:
Tallest Angiosperm: Eucalyptus
Smallest Angiosperm: Wolffia(duckweed/watermeal)
-Angiosperms undergo double fertilization in which one of the sperm fuses with the egg cell to form a zygote and the other sperm fuses with the polar nuclei to form the triploid endosperm which is rich in nutrients.
-At the end of fertilization or the post-fertilization events involves the formation of seeds and fruits from ovules and ovaries respectively.
