Document Summary
Is photosynthetic (has a giant chloroplast: has an eyespot within it: senses the light environment linked to flagella movement. Eukaryotic (has a nucleus: has all the typical organelles (golgi, er, mitochondrion, ribosomes, anything that have chloroplasts also have mitochondria. Have traits of both plants (photosynthetic) and animals (mobile) classified as green algae. No division of labour, all cells are the same and perform the same way. Both sexual or asexual reproduction stages (depends timing) Zygote can be very resistant to heat or cold. Increase in genome size = increase in protein coding genes. Humans have 20x bigger genome size than chlamy, but it only codes for 5000 more proteins. Sodium transport required for survival, heat resistance, alanine biosynthesis, photosynthesis (>1000 genes) Some traits single genes, some require multi genes: intentionally mutate some genes in genome mutagenesis. Inserts randomly into genome and destroys the function of the gene. Spin down chlamy and combine with bleomycin electroporation.
