Question

I need short answer for each question please

Question 6: List two ways that A and B are different, with a brief explanation. PAS Figure 4 Question 7: How are multicellular green algae like land plants? How are they different? Question 8: Water lilies, like the name implies, live in water, like ponds. They are flowering plants that make seeds, so are part of the land plant group. How can this be? Question 9: Consider the bryophyte life cycle. How is a sporophyte formed? Question 10: Some seeds can exist in a dry state for a very long time, seemingly not even alive, but then germinate when conditions are right. How might this be an adaptive advantage for species of plants that live in very harsh environments?

Answer 1

6.

A is sporophyte whereas B is gametophyte.

In the image given, sporophyte is dependent upon gametophyte which is photosynthetically independent.

The sporophyte is diploid and contains a capsule which has spores in it. The gametophyte is haploid and gives rise to gametes.

7. Similarities -

Eukaryotic cell

Presence of cellulosic cell wall

Chloroplast and chlorophyll present and able to undergo photosynthesis

Starch is the reserve food

Both are embryophytes.

Differences -

Land plants are differentiated into roots, stem and leaves whereas algae is undifferentiated.

Vascular tissue is absent in algae but present in some plants.

Algae always show external fertilization but plants show both internal and external fertilization.

According to the guidelines, only first question can be answered. Still I have answered two for you. Please give a good rating.
