Question

14 multiple choice 2 points you travel back in time and find a 15 meter tall giant fern. that giant fern... is the gametophyte is a haploid thallus is made of cells produced by meiosis which are then copied by mitosis. is the diploid sporophyte 15 multiple answer 2 points which of the following characteristics do land plants share with green algae? use of chlorophyll a and b use of starch as an energy storage product cell walls made of cellulose chemoheterotrophic energy/carbon acquisition

Explanation:

1. In ferns, the dominant and larger - sized phase is the diploid sporophyte. The gametophyte is small and short - lived. A haploid thallus is not characteristic of the large fern structure. Fern sporophytes are made of cells produced by mitosis after the zygote formation (zygote is diploid). So, the 15 - meter tall giant fern is the diploid sporophyte.
2. Land plants and green algae share several characteristics. They both use chlorophyll A and B for photosynthesis, store energy as starch, and have cell walls made of cellulose. Chemotrophs obtain energy from chemical compounds, and land plants and green algae are photoautotrophs (not chemoheterotrophs) as they use light energy to produce their own food from carbon dioxide and water.

Answer:

1. Is the Diploid Sporophyte
2. Use of Chlorophyll A and B, Use of Starch as an energy storage product, Cell walls made of cellulose
