Document Summary
Controls cell shape and strength internal skeleton. Provides a scaffold for cell wall assembly (e. g. plant cell walls) Co-ordinates segregation of genetic material and organelles during cell division (mitosis and meiosis) Single eukaryotic cells e. g. protists move through their environment. Gastrulation, neural crest cells, new neurons in the developing brain. Some cells have cilia and others have flagella. On the right is what the cell looks like, it is covered by cilia which row in unison in order for the movement to occur. Eutreptiella moves by a combination of amoeboid movement and flagella beating. Weird cell which schmoozes like and amoeba and the flagella are going on. Beating of cilia or flagella powers movement of single cells. Sperm cell and how the long flagella beats like a whip. Animal gastrulation and neurulation: embryo shape changes through cell. Likened to the idea of a power stroke movements. Blastula a very early egg of the frog.
