Similarities in nuclear and chloroplast genes

Question 4

Answer 4

The protective layer charophytes Which allows them to tolerate occasional drying along the edges of ponds and lakes

Question 5

What are some characteristics that distinguish charophytes from other plants

Answer 5

Plants have cuticles, stomata, multicellular dependent embryos, while the spores produced in sporangia, Population of generation, and ethical meristems

Question 6

Describe the alteration of generations

Answer 6

1) Gametophyte enters my mitosis (hapliod n)
2) Gametophyte enter fertilization (haploid n)
3) The Gametophyte turn in to zygote (diploid 2n)
4) The zygote goes through mitosis
5) After my house as it turns into a sporophyte
6) The sporophyte goes through meiosis
7) turns into two n spores(haploid)
8) spores go through mitosis to turn back into a Gametophyte (haploid)

Answer 11

Gametophytes

Question 12

What are bryophytes and some examples

Answer 12

nonvascular plants that have a lineages Leading to the three extent clades

Ex) Liverworts, masses, and hornworts

Question 13

What does the dominant generation of bryophytes consist of

Answer 13

Haploid gametophytes 

Question 14

What is the role rhizoids

Answer 14

They anchor gametophytes to the substrate in which they grow

Question 15

What produces the flagellated sperm

Answer 15

Antheridia

Question 16

What do flagellated sperm require

Answer 16

A film of water to travel to the eggs in the archegonia

Question 17

Describes what happens in the diploid state of the life cycle

Answer 17

The sporophytes grow out of archegonia and attach to the gametophytes

Depends on gametophytes for nourishment

Question 18

What do smaller simpler sporophytes consist of

Answer 18

A foot, seta aka stalk and sporangium
