Question

Identify each statement as TRUE or FALSE. a. Plants are defined as multicellular, eukaryotic, photosynthetic autotrophs. b. Plants are defined by their chloroplasts, which contain chlorophyll a and b. c. Charophytes and land plants share four derived traits that suggest they share a relatively recent common ancestor. d. Charophytes are embryophytes.

Answer 1

A. True

B. True

C. True

D. False

Step-by-step explanation:

A. Plants in general are multicellular organisms, they are often referred to as eukaryotic autotrophs because they are make their own foods. They carry out photosynthesis, meaning the obtain their energy from sunlight.

B. Plants can be characterized by the presence of chloroplast, an organelle that helps in absorption of sunlight, because of the presence of green pigment called chlorophyll. There two major forms of chlorophyll in plants which are chlorophyll a and b.

C. Charophytes are a type of green algae, but several studies shows they have similar traits to land plants compared to other algae, making them have a common ancestor as plants. Some of the traits similarities to land plants compared to other algae are: they have similar enzymes, they have similar type of cell division, also their sperm is also similar to that of land plants.

D. Charophytes are not embryophytes. Embryophytes are also referred to as land plants, they are multicellular in nature, they include ferns and mosses. Charophytes are a type of green algae similar in traits embryophytes. Although embryophytes are a sister group to charophytes, they are not the same.
