Answer 1

1. (a) Monoecious are the type of plant or invertebrate animal which have both male and female reproductive organ in a same body.

(b) Dioecious are the type of plant or invertebrate animal which have both male and female reproductive organ in a different body.

So the correct answer is- (a) Monoecious.

2. Ovule is the part of the flower which matures into seed.

(a) Ovary is the reproductive organ of the flower which consists of ovule and it matures into seed.So this option is correct.

(b) Stigma acts to catch the pollen of the flower it is a seperate part of the flower. So this option is incorrect.

(c) Style is also a sub part of the stigma. So this option is incorrect.

(d) Anther is the male structure it is at the top part of the stamen. So this option is incorrect.

(e) Corolla is the petal of the flower it does not holds the ovule. So this option is incorrect.

3.  Dicotyledonae (Dicots) has reticulate type of vein on the leaf.it also has taproot type root and they consists of 4,5,10 stamen but where the Monocotyledonae (Monocots) has parallel vein on the leaf,fibrous type root and usually they have three stamen.

So the correct answer is- (b) Dicotyledonae (Dicots)

4. The double fertilization occurs only in the angiosperms but it does not found in other type of plants. Coniferophyta belongs to the angiosperm catagory.

So the correct answer is- (b) Coniferophyta

5. Only the flowering plants or Gymnosperm needs pollinators like ant,bee,beetles,butterflies etc

(a) Pterophyta are the fernwhich deos not have flower.So this option is incorrect.

(b) Anthophyta are the gymnosperm which needs pollinators like ants,bee,butterflies etc.So this option is correct.

(c) Coniferophyta are gymnosperm but it does not have flowers so that it does not need any pollinator. So this option is incorrect.

(d) Bryophyta belongs to the moss group which does not have any flower so they does not need any pollinator. So this option is incorrect

6. One ovule develops only one seed.

So the correct answer is- (a) One

7. (a) Banana develops from a flower. So this is a fruit. So this option is incorrect.

(b) Tomato also develops from a flower. So this is also a fruit. So this option is incorrect.

(c) Zucchini also develops from a flower.So this is a fruit. So this option is incorrect.

(d) Cbbage is a leafy plant it has not develop from flower. So this is not a fruit. So this option is correct.

So the correct option is- (d) Cabbage.

8. Spicukes or spongin and asymmetrical structure found in sponge which belongs to the phylum Porifera.

So the correct answer is- (d) Porifera

9. The Corals, sea anemones, and jellyfish are diploblastic and they also have nervous system and some sensory organs. So they belons to Cnidaria.

So the correct answer is- (b) Cnidaria

10. The Polyp body form looks like a cup like structure and the Medusa body form looks like a cap. The jellyfish body also looks like a cap like structure.

So the correct answer is- (a) Medusa.

11. All the animals snail,earthworm,shark they all eats food so they they must need to digest the food to yeild nutrient and energy but the tapeworm just ansorbs the nutrients from its host it does not need to digest any food as it absorbs the nutrients which is already digested.

So the correct answer is- (b) A tapeworm.

12. The parasitic worms, Trichinella, Enterobius (pinworms), and Ascaris all belongs to the Nematoda because they have a bilaterally symmetrical body and they also lack of digestive system as well as their body is covered with collagenous cuticle.

So the correct answer is- (c) Nematoda.
