b) A cavity in the ovule in which pollen grains are stored after pollination

c) An opening in the megagametophyte through which the pollen tube approaches the egg

1             (a)

In gymnosperms the dominant phase is sporophyte, gymnosperms are heterosporous produced haploid megaspore and microspores, which are produced with in sporangia born on sporophyll. These spore bearing plants are called sporophytes

2             (a)

Liverworts reproduce asexually by the formation of specialised structure called gemmae or through fragmentation of thalli. Gemmae are asexual buds, which originate from small receptacles called gemma cups

3             (d)

Bryophytes are also known as amphibians of plant kingdom. They have various features, which enabled them to live on both land and on water habitats

4             (b)

Professor M O P Iyenger is know as father of Inidan phycology.  Phycology is the study of algae (chlorophyllous thallophytes).

Professor K C Mehta worked on cause behind annual recurrence of wheat rust (fungi, i.e., non-chlorophyllous thallophytes) in plains of northern India.

5             (a)

Sago starch is obtained from Pinus

6             (c)

The primary endosperm nucleus is triploid (3n) as it is the product of triple fusion

7             (c)

A-Antheridiophore, B-Archegoniophore, C-Gemma cup

8             (a)

Genera like Selaginella and Salvinia, which produce two kinds of spores, macro (large) and micro (small) spores are known as heterosporous

9             (c)

Pinus is either monoecious or dioecious. In monoecious condition male and female strobili are present on same plant and dioecious condition male and female strobili are present on different plant. Cycas have only dioecious condition

10           (a)

Agar (agar-agar) is polymer of D-galactose 3-6 anhydro L-galactose having sulphate esterification after tenth galactose unit.

11           (a)

Gymnosperms are naked seeded plants because seeds are presents on the megasporophyll and are not enclosed with fruit wall due to lack of ovary wall.

12           (c)

A-Dictyota, B-Polysiphonia, C-Porphyra, D-Laminaria, E-Fucus

13           (a)

Filament and anther.

Male sex organ is stamen also known as androecium. It consists of an anther lobe and a filament. Anther produces pollen grains

14           (c)

Cycas are heterosporous and in additions, produce highly specialised complex reproductive and dispersal structure called seeds. Cycas is also a dioecious plant. Dioecius plants are unisexual, having male and female reproductive organs on different individual (plants)

15           (b)

Chilgoza a gymnospermic seed that is eaten as dry fruit is produced by Pinus gerardiana

16           (a)

In moss (Funaria), the dispersal of spores is facilitated by hygroscopic pouring movements of peristomial teeth (lengthening and shortening of peristomial teeth). The inner peristome acts as a sieve allowing only few spores to escape at a time.

17           (b)

Bryophytes lack true-roots, stem or leaves. They possess root-like, leaf-like or stem-like structures

18           (a)

In Cycas, ovules are found without ovary, this condition is called naked ovule.  Cycas produces largest ovules in the plant kingdom. The ovules are orthotropous and unitegmic.

19           (c)

Maiden hair fern, the common name given to the fern Adiantum capillus veneris, in which leaves are bi-pinnate with sori (clustered stalked sporangia) present sub-marginally.

20 (b)
