2.3) : Capsule is the center for spore formation and it is present at the tip of sporophyte.
2.4) : The sporophyte of moss develops some structure to adpat to terestrial habitat. These are : Presence of stomata in the sporophytic plant body, primitive vascular strands runs in sporophyte's stem, sporophytic plant body is not fully depend on gametophyte for nutrition due to presence of chlorophyllus tissue, multilayed capsule and presence of air chamber.
Question 3 :
3.1 : This is a angiosperm plant beacuse ovary are enclosed in carpel and possed ovule in it.
3.2 : Part A is stigma and part B Is style and part C is ovary.
3.3 : Female gamete is produced in ovule letter G represent the ovule.
3.5 : this flower is self pollinated fower because it posses both female and male reproductive part together. 3
3.6 : Lettter D indicate ovary which develop into fruit in later stage.
