Document Summary
Chloroplast: organelle containing chlorophyll which acts as the site of photosynthesis. Cytoplasmic straining: vacuole moves nucleus around the cell. Endomembrane system: making, packaging and shipping proteins and molecules. Nucleolus: sub-compartment of the nucleus, site of rrna synthesis. Nuclear pores: channels that allow the movement of certain molecules between the cytoplasm and nucleoplasm. Nucleus: membrane bound organelle containing the cell"s dna. Primary endosymbiosis: between a eukaryote and a cyanobacterium that produces a plastid with two membranes (glaucophytes, red algae and green algae/plants). Secondary (eukaryotic) endosymbiosis: involves di erent hosts and any of the algae that contain a primary endosymbiont. Secondary endosymbioses have produced a wide range of protist lineages, such as the chromists, euglenoids and alveolates. The dominant feature of this cell is the nucleus, containing most of the cell"s dna. The nucleus is surrounded by a double membrane called the nuclear envelope. Nuclear (annular) pores are organised and complex containing multiple.
