3. Eusporangiate

4. Xylem and phloem

5. Dominant and independent sporophyte

6. Gametophyte is dependent on the sporophyte for nutrition

7. Reproduce by seeds

gorged with digested products of the endosperm (in angiosperms), enclosed within the remains of the
megasporangium and covered with one or more integuments



3 generations of the seed - Answer 1. female gametophyte (gymnosperms) or endosperm
(angiosperms)

(remains of the megesporangium + integuments)



ovule - Answer megasporangium/female gametophyte surrounded by integuments



Integuments - Answer Tissue covering around megasporangium

, Origin: parent sporophyte (2n)

Fate: becomes the seed coat



Characteristics of advanced heterospory - Answer 1. Produce ovules

2. Female gametophyte develops within the megasporangium

3. Male gametophyte starts development within the microsporangium

4. Process of pollination

5. Following pollination, pollen germinates to produce mature male gametophyte

6. Zygote → Embryo



Pollination in gymnosperms - Answer transfer of pollen from the microsporangium to the pollen
chamber of the megasporangium



Polination in angiosperms - Answer transfer of pollen from the anthers to the stigma of the pistil



Immature male gametophyte - Answer pollen
