Which of the following is NOT a similarity between land plants and green algae?
- a. Photosynthesis
- b. Starch as a storage form of energy
- c. Cellulose cell walls
- d. The presence of a cuticle and stomata
Introduction:
Green algae are the closest relatives of plants, some plants are also called charophytes. Both share most of the common features, they both are multicellular, they have cellulose cell wall and show photosynthesis.
Answer to Problem 1MCQ
Correct answer:
The stomata and cuticle are the adaptions of plants. Therefore, option d. is correct.
Explanation of Solution
Reason for the correct statement:
The plants can obtain and conserve resources by the stomata and cuticle. Plants can exchange gases through stomata. A cuticle is a lining of wax which makes water and gases impermeable to leaves. So, both stomata and cuticle are not present in green algae; they have cellulose and photosynthetic pigments.
Option d. is given as “The presence of a cuticle and stomata”.
As, “The presence of a cuticle and stomata is not a similarity between land plants and green algae”, is the right answer.
Hence, the option d. is correct.
Reasons for the incorrect statements:
Option a. is given as “Photosynthesis”.
The plants carry photosynthesis with the help of photosynthetic pigments CO2, water and minerals. The same photosynthetic pigments are present in green algae. This answer does not support the statement. So, it is a wrong answer.
Option b. is given as “Starch as a storage form of energy”.
Starch is present in both plants as well as in green algae and used as a nutrient reserve. This answer does not support the statement. So, it is a wrong answer.
Option c. is given as “Cellulose cell walls”.
The cellulose-rich cell walls are present in both green algae as well as in land plants. This answer does not support the statement. So, it is a wrong answer.
Hence, options a., b., and c. are incorrect.
The stomata and cuticle waxy linings are only present in land plants. The stomata opening is for the respiration and cuticle is an adaption in plants to protect the plant from water.
