Question

What are the 4 things that make plants unique to their algae ancestors?

Answer 1

Four things that make plants unique to their algae ancestors are:

1. Plants have connective tissues that helps to transport nutrients and water throughout the plant. While in algae, each cell absorbs its own water. This makes algae non vascular.

2. Plants are multi-cellular that consists of chloroplasts, cellulose walls and also have the ability to make embryos while algae are generally single celled.

3. Algae majorly thrives in water that uses the minerals found in water to produce their own food but some can live on land and even on snow. However, Plants mostly grow on land because they use sunlight and CO2 to keep some of its most important biologic processes going on.

4. The mode of reproduction in plants is more complex compared to that of algae which is primitive.

Answer 2

The four ways by which land plants later evolved and became unique from their algal ancestors are:

Step-by-step explanation:

The ancestors or close relatives of land plants are the green algae also called the charophytes. Land plants became unique from their algal ancestors due to evolutionary changes required for adaption with the environment.

1. Alteration in the successive generations of plant species, produces gametes and sporophytes through mitosis and meiosis.
2. Embryonic growth at multicellular level, obtains nutrient from parent cells.
3. Plants produces spores through sporangia and have multicellular gametangia
4. Growth of plant occurs through apical meristems by differentiation of tissues
