Question Answer
What are sex cells formed by meiosis with only half of the chromosomes They are haploid
Plants release these into their surroundings to produce offspring spores
the joining of two haploid cells begins in this stage sporophyte stage
When an egg and sperm combine fertilization occurs
depending on the species of plant these organs can be on the same or different plants reproductive organs
after fertilization this plant produces berries holly produces berries
this stage begun when cells in reproductive organs undergo meiosis and produce haploid cells gametophyte stage
asexual (blank) does not require the production of sex cells reproduction
(Blank) have a full set of chromosomes diploid cells
(blank) are something all organisms have in common life cycles

*Remember to know the structures in a fern's reproductive cycle* *Remember to know the structures in a fern's reproductive cycle*
In (blank) reproduction a new plant can be brown from a leaf, stem, or root. asexual
In (blank) reproduction a sperm cell fertilizes an egg cell to form a zygote sexual
The (Blank) stage begins when sex cells produce haploid cells called spores Gametophyte
The (Blank) stage begins with fertilization Sporophyte
Seedless plants do not produce (blank) seeds
The (blank) of seedless plants grow into plants that produce sex cells Spores
All nonvascular and some vascular plants are (blank) seedless
The gametophyte stage produces (blank) sex cells
The sporophyte stage produces (blank) spores
When spores are (blank) and land in an appropriate environment they can grow into new gametophyte stage plants released
Most vascular seedless plants are (blank) ferns
Fern plants have (blank) that grow from an underground stem called a (blank) fronds, rhizome
Fern (blank) are produced in sori, which are usually on the underside of fronds spores
A fern spore that lands in a favorable environment grows into a gametophyte plant called a (blank) prothallus
(blank) form in prothallus sex cells
When fertilization occurs, the (blank) starts the sporophyte state zygote
Ferns may reproduce (blank) when rhizomes form new branches and are separated from the main plant asexually
