in the fruit

in the roots

under the leaves

inside the flowers

2. Fern spores usually form during:

spring

winter

summer

fall

3. Why must the plant which grows directly from the fern spore be wet?

in order to produce a seed

so that the egg can be fertilized

so that it can grow

4. Spores are formed in:

ovaries

spore cases

anthers

5. Ferns grow by:

photosynthesis

reproduction

mitosis

6. How do spores help sustain the population of ferns?

Spores do not have any natural predators.
There are million of spores that are made by a single plant to help keep its population.

Spores can hide under rocks for long time before maturing into an adult plant.

Spores can live for a long time without maturing into an adult plant.

7. Choose all the right answers.

When the leaf of a fern touches the ground, it may produce a new plant:

by planting a spore

by vegetative reproduction

by growing roots at the point of contact

by budding from its stem

1: C. They are found contained in a casing, called sporangia, and grouped into bunches, called sori, on the underside of the leaves.

2: C. The sporophyte generally releases spores in the summer. Spores must land on a suitable surface, such as a moist protected area to germinate and grow into gametophytes.

3: B:  Moisture is needed for germination, growth and fertilization and high humidity for prothalli and young developing ferns after fertilization.

4: B. In ferns, spores are contained within cases called sporangia that are located on the underside of leaves.

5: C. Each spore grows into a photosynthetic prothallus (gametophyte) via mitosis. Because mitosis maintains the number of chromosomes, each cell in the prothallus is haploid.

6: D. the reason why that's the answer is because I read a national geographic paper and it said that spores can live for over a million years without maturing into an adult plant .

7: A and B. Walking fern also has another, asexual, way of reproducing. If the long extended leaf tip touches soil, a new plantlet can form at the tip, produce roots, and become a new plant. The new plant can then grow a long leaf which touches the ground and sprouts another plantlet. In this way the colony gets larger and larger.

I hope this helped, have a great day! :)
