Moss and Fern Life Cycles

What can some mosses and liverworts do?

• reproduce in a single cycle

• uncurl their leaves into fronds

• break rock into soil

• live for more than 300 million years

When mosses and ferns reproduce, what do they produce in the first cycle?

• spores

• fronds

• sperm

• egg

Mosses were the first plants to evolve, with no vascular tissue or seeds.

• TRUE

• FALSE

Spores are better than seeds because spores have a short lifetime

• TRUE

• FALSE

How are mosses and ferns alike?

• They both have fronds

• They both reproduce without seeds

• They both grow only at night

• They both grow in the oceans

In fern's life cycle, when does fertilization occur?

• when the egg and sperm fuse

• when spores germinate

• when the young gametophyte releases sex cells

In moss' life cycle, how does a sperm cell get to an egg cell?

• through the help of water

• through self-pollination

• through cross-pollination

• through the help of the wind
