DAT Biology Final Exam Study Set 2024/2025 with Verified Q&A Carotenoids - CORRECT ANSWER-lipid derivatives, produce pigments in plants and animals , An accessory pigment, either yellow or orange, in the chloroplasts of plants. By absorbing wavelengths of light that chlorophyll cannot, carotenoids broaden the spectrum of colors that can drive photosynthesis. Porphyrins - CORRECT ANSWER-lipid derivatives, a group of light-sensitive, pigmented, ringed chemical structures that are requi...

Know the different between prokaryotic and eukaryotic cells - Answer-Prokaryotes: -No membrane bound organelles -Lack of membrane bound nucleus. (DNA is present in the nucleoid) -Consists of cytoplasm surrounded by plasma membrane and encased within a cell wall. Eukaryotes: -Possess a membrane bound nucleus -More complex than prokaryotic cells -Important aspect is compartmentalization -Possess cytoskeleton for support and to maintain cellular structure. Know the structures of the cell d...

BIOL 141 Exam #2 Study Guide Questions And Answers A+ Review Eukaryotic vs Prokaryotic - Correct Answer->Eukaryotic cells contain membrane-bound organelles, such as the nucleus, while prokaryotic cells do not. Differences in cellular structure of prokaryotes and eukaryotes include the presence of mitochondria and chloroplasts, the cell wall, and the structure of chromosomal DNA. Significance of surface area to volume ratio and square-cube law for determining cell size - Correct Answ...
