Answer 47


Question 48

Alternation of Generations

Answer 48

- sporophyte (diploid) produces spores (haploid) by meiosis - gametophyte (haploid) produces gametes (haploid) by mitosis - gametes (haploid) fuse to form zygote (diploid) which develops into sporophyte

Question 53

Vascular Seedless Plants Life Cycle

Answer 53

Homospory-produce one spore which produces gametophytes by mitosis heterospory- megaspores divide by mitosis to produce female gametophyte microspores divide to produce male gametophyte

Question 54

Vascular Seedless Plant Alternation of Generations

Answer 54

- sporangium (2n) on sporophyte (2n) produces spores (n) by meiosis - spores (n) grow into gametophyte (n) - gametophyte produces sperm (n) and egg(n) - fertilization produces new sporophyte (2n)
