Movement of organelles (microtubules)
Generate contractile forces (actin filaments)
Strengthen cell (intermediate filaments)
- The ancestral eucaryotic cell was a predator that fed by capturing other cells. Such a way of life requires a large size, a flexible membrane, and a cytoskeleton to help the cell move and eat. The nuclear compartment may have evolved to keep the DNA segregated from this physical and chemical hurly-burly, so as to allow more delicate and complex control of the way the cell reads out its genetic information.

5 True/False questions
Chloroplasts → Consists of cytosol--->jelly-like mixture
Consists of organelles
Cytoplasm → Contain own DNAand reproduce by dividing in two.
Thought to derive from bacteria that were engulfed by some ancestor of present-day eucaryotic cells, creating a symbiotic relationship.
Contain chlorophyll/enzymes involved in photosynthesis to generate sugar and oxygen.
Generate food and oxygen for mitochondria to use.
Nucleus → Temporary storage organelles involved in transport by the processes of endocytosis/exocytosis
Procaryote = before nucleus → Contain Bacteria/Archaea
Ribosomes → Protein synthesis
