Answer 1

Chegg's guidance allow us to answer first 4 question.Kindly re post other question

Answer 1 – [True] The ancestors of plants were probably algae.

Explanation – It is probably true because land plants originate from ocean plant.

Answer 2 - Plants and green algae both are capable of processing photosynthesis. They both are consider to be photosynthetic Eukaryotes and consist of complex Multicellular bodies.

Answer 3- The most important advantage of life in land is the presence of sunlight which is absolutely absent in the aquatic plants. It is also be beneficial for the animals who are herbivorous.

Answer 4- Disadvantage include the reproduction without water , they have to obtain resources from the ground and air.
