Document Summary
Single celled, photosynthetic, giant chloroplast, has a nucleus therefore eukaryotic, has endoplasmic reticulum, golgi, mitochondria, and ribosomes. Anything that has a chloroplast also has a mitochondria. Chloroplast: contains an organelle eyespot that senses the light environemt and signals for the cell to move away or towards light. Phylogeny: it is both a plant and animal because it uses light as energy and information; although its photosynthetic, its ability to sense light environments and move is an animal attribute. It undergoes asexual reproduction, but under conditions of environmental stress, it can sexually reproduce . Positive and negative gametes are produced (2 mating types) that then undergo fertilization and meiosis. Genome size and evolution of species as genome size increases, so does protein coding genes. Humans have 20x bigger genome size but only codes for 5000 more proteins (why?) Some traits require one gene (na+ transport) while others require hundreds of genes (photosynthesis)
