Sexual Reproduction in Plants

Flashcards covering section 9.2 Sexual Reproduction in plants, including mechanisms in different plant groups and the plant lifecycle diagram.

What does sexual reproduction in plants involve, similar to animals?

It involves the fertilization of gametes (egg and sperm) and the formation of a zygote and embryo.

What term is used in the text to refer to seed plants?

spermatophytes

Why do bryophytes and pteridophytes need water, such as dew or rain, for reproduction?

Their sperms act like little swimmers that must move through water to find the egg cells.

Which two groups of seed-producing plants do not rely on water to transport their sperms to egg cells?

gymnosperms and angiosperms

What general cycle is depicted in Figure 9.14?

Lifecycle of plants

According to the plant lifecycle diagram (Figure 9.14), what process produces haploid spores ($n$) from the sporangium?

Meiosis

According to the plant lifecycle diagram (Figure 9.14), what process produces gametes (sperm and egg) from the gametangium?
