Homework Answers
Green Algae have the pigments which are most similar to land plants.
1. Green algae contain chlorophyll a and chlorophyll b (bright green), beta carotene (red-orange) and xanthophylls (yellow).
2. Brown algae have a unique brown to yellow appearance. It contains pigments like chlorophyll a, chlorophyll c, fucoxanthin, β-carotene, and xanthophylls.
3. Red algae have following pigments - chlorophyll a, chlorophyll d, β-carotene, and phycocyanin.
Land plants contain the carotenoids and chlorophyll a and b just like green algae. Red and brown algae have types of chlorophyll molecules in addition to chlorophyll a. They have also different accessory pigments.

Question 25 1 points The ancestor of land plants is thought to be related to charophytes, a type of green algae. Why might it be advantageous for charophytes to undergo sexual reproduction? a. Charophytes, like land plants, have plasmodesmata, which need to be generated by sexual reproduction, b. Sexual reproduction produces larger numbers of offspring in less time. c. They are multicellular when conditions are unfavorable, which favors sexual reproduction d. Sexual reproduction produces multicellular...
