Answers:
1.)
Solution:(a) Angiosperms
Angiosperms are also known as flowering plants and their seeds are enclosed in a fruit.
2.)
Solution:a) The integument
The integument is present around the ovule which protect ovule. A cell layer that is divided into inner and outer integument.
3.)
Solution: (c) Dicotyledons
Dicotyledons are characterised by seeds having two cotyledons, leaves with reticulate venation and tetramerous or pentamerous flowers.
4.)
Solution:d) It contains androecium and gynoecium on the separate flowers.
When androecium and gynoecium are present on the separate flower then it is known as unisexual flower. Unisexual flower is also called as Incomplete flower.
5.)
Solution:(b) Anther
The three main parts of the female sex organ pistil of a flower are stigma, style and ovary.
6.)
Solution:d) All of them
Bothe the androecium and the gynoecium are present in the bisexual flower. So, it is a complete flowers. Also, complete flower is known as androgynous or hermaphrodite.
7.)
Solution:(b) Ovary
The fertilisation of male and female gametes occur in the ovary, a part of female reproductive organ.
8.)
Solution:b) Attract insects to the flower
Corolla is composed of Petals and these are brightly colourful. Brightly coloured flower are present to attract insects to the flower.
9.)
Solution:b) (ii) (iv) (i) (iii)
Monocotyledons have parallel venation in their leaves, and dicotyledons have reticulate venation. Anther is a part of stamen and stigma is a part of pistil.
10.)
Solution:d) Sepals
Green leafy structure form calyx, it is referred to as Sepals. Inner part of the flower is protected by Sepals.
11.)
Solution:(a) Trimerous
Flowers of the category monocotyledons possess trimerous flowers. They have three members in each floral whorl.
12.)
Solution:a) Ovule
In the Angiosperms, ovules of the flowering plants eventually develop into fruits. This happens inside the ovules.
13.)
Solution:(d) Polar nuclei → 3
In an egg apparatus, there are 1 egg cell, two synergids, three antipodal cells and two polar nuclei.
14.)
Solution:c) Hiptage
Tribules is an example of Trailers, Grape vine is an example of Climbers and Vanda is an example of Epiphytes. Hiptage is a right answer which is an example of Lianus.
15.)
Solution:(c) Pollination
Pollination is the process in which the pollen grains after dispersal from the anthers are carried by wind and various other means to the stigma of a pistil.
16.)
Solution:c) Zone of division
17.)
Solution:(c) Triploid
One of the male gametes fuses with the diploid secondary nucleus to produce the PEN which is triploid.
18.)
Solution:a) Heterotrophic
When plant take their nutrition from other sources then it is heterotrophic type of nutrition. Parasites are included in the heterotrophic angiosperms.
19.)
Solution:(d) Angiosperms
Double fertilisation which includes syngamy and triple fusion is a unique feature of angiosperms.
20.)
Solution:d) Morphology
Morphology is the branch of biology that mainly studies structure and size of an organism. Or Morphology studies external appearance of an organism.
21.)
Solution:(a) (i)→ (iv)→ (v)→ (iii)→ (ii)
In the case of double fertilisation, the pollen grains land on stigma and germinate resulting in the formation of pollen tube that releases the two male gamete into the embryo sac. One male gamete then fuses with the egg cell and the other male gamete fuse with the secondary nuclei.
22.)
Solution:b) A-ii), B)-i) and C-iii)
Wheat is an example of Herb, Jasmine is example of Shrub and Dalbergia is an example of Tree. So, this is the right pair.
23.)
Solution:(c) Primary Endosperm Nucleus
Primary Endosperm Nucleus (PEN) develops into the endosperm and provides nourishment to the developing embryo.
24.)
Solution:a) Opuntia
Opuntia is an example of Succulents. Other remaining are examples of Mesophytes.
25.)
Solution:(b) Pinus
Out of the options provided only rose, eucalyptus and lillies belong to angiosperms.
26.)
Solution:b) Darwin
Charles Darwin was the one who described the origin of the Angiosperm as ‘Abominable mystery’. Also, the spread of Angiosperms is described as ‘Abominable mystery’ by him.
27.)
Solution:(a) Bamboo
Bamboo is an example of monocotyledon plants.
28.)
Solution:c) More reproductively successful
In the angiosperms, flower pollination with the help of animals or bees is more reproductively successful. The pollination takes place in exchange for nectar.
29.)
Solution:(b) Stamens
The egg apparatus mainly contains an egg cell, synergids, antipodal cells and polar nuclei.
30.)
Solution:a) Seed Containers
In these Greek words, Angion refers to container and Spermo refers to seed. Angiosperms refer to Seed Container.
31.)
Solution: c) Anther
The given diagram is shows structure of Anther in the Angiosperm. The Anther is the upper most part in the Structure of Anther which contains pollen grains.
