Subphylum Sarcodina
Basic Diagrams
Key:
A) Nucleus - the main central portion that contains the karyosome and chromatin.
B) Karyosome - a clump of chromatin material found within the nuclei of amoebae.
C) Peripheral nuclear chromatin - the part of the nucleus that contains the genetic
material.
D) Cytoplasm - the inner material or an amoebae excluding the nucleus.
E) Inclusion - particles and objects that are embedded in the cytoplasm.
F) Pseudopod - cytoplasmic protrusions that is the organelle of locomotion.
G) Chromatoidal bar - rod shaped mass of RNA.
H) Vacuole - a fluid filled sac within the cytoplasm.
