In this lesson our instructor talks about subcellular structure.
First, she talks about prokaryotic cells. Second, she talks
about eukaryotic cells structure. Then she talks about the
cytoskeleton. Finally she talks about plant cell structure. Four
complete example videos round up this lesson. have cell walls
containing peptidogylcan. Some bacteria are covered by a capsule
that helps them to evade the immune system. genetic material in
bacteria found in the nucleoid region. Some bacteria also have
small rings of DNA called plasmids, which contain are
projections from the bacterial surface. Sex pili transfer DNA
from one cell to another. provide a means of motility in some
prokaryotes. cells contain membrane bound organelles including
rough and smooth endoplasmic reticulum, Golgi apparatus,
mitochondria, lysosomes, peroxisomes and ribosomes. DNA is
organized as chromosomes bound by histone proteins and is
located within a membrane bound nucleus. The nucleolus is the
site of ribosomal RNA synthesis. cytoskeleto
