Plants and animals can reproduce asexually and sexually.
Commercial growers often clone prize-winning plant varieties to guarantee that offspring are genetically identical to the parent. State one artificial method of vegetative propagation used to achieve this asexual reproduction.
Complete the comparative table below, which contrasts the reproductive structures and cells of angiosperms (flowering plants) and humans.
| Feature | Flowering plants (Angiosperms) | Humans |
|---|---|---|
| Female gamete | (i) ____________________ | Egg cell / oocyte |
| Site of male gamete production | Anther | (ii) ____________________ |
| Anatomical location of fertilisation | (iii) ____________________ | Oviduct / fallopian tube |
From an evolutionary and physiological standpoint, explain why mammalian spermatozoa are highly streamlined (small) and produced in millions, whereas mature ova are much larger and produced in very limited numbers.
