Plant Structures for Reproduction

The seeds of a plant forms in its

• stamen

• ovary

• pistil

• petal

A fruit, like an orange or an apple, sometimes forms around a seed to

• protect it

• fertilize it

• supply food

• provide nutrients

When a male and female structure combine, it is called

• circulation

• fertilization

• multiplying

• sprouting

Why is it important for seeds to be able to scatter?

*CHOOSE ALL THAT ARE CORRECT!*

• so they can grow in a new area that may better sunlight

• so they can grow in a new area that may have more water

• so they can grow in a new area with more nutrients

• so that animals and insects can eat them

What is a sporophyte?

• The stage that produces sperm cells and egg cells

• The spore-producing stage.

• The rhizome that produces roots and leaves.

• The slender, hairlike threads of cells.

What is gametophyte?

• The stage that produces sperm cells and egg cells.

• The spore-producing stage.

• The rhizomes that produces roots and leaves.

• The slender, hairlike threads of cells.

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

• spores
• fronds
• sperm
• egg

What do spores become after they are released from sporophytes?

• liverworts
• rhizoids
• cryptophobic
• gametophytes

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
