1.1 The Two Major Cell Types

  • Prokaryotic cells — often in single-cellular cells, has a cell wall, and contained in capsules
  • Eukaryotic cells — in multicellular cell elements, contains a plasma membranes and nucleus

1.2 Prokaryotic vs Eukaryotic Cells

Prokaryotic Cells Both Eukaryotic Cells
Cell wall DNA Plasma membrane
Capsule container Cytoplasm Nucleus
  Ribosomes Mitochondria
  Membranes  

1.3 Eukaryotic Cells, a deep dive

1.3.1 Plant and Animal Cells, Compare and Contrast

Animal Cells Plant Cells
Has soft plasma membrane Has hard cell wall
No chloroplast Has chloroplast to do photosynthesis
Has cytoplasm Has cytoplasm
Has Ribosomes Has Ribsonmes
Has mitochondria Has mitochondria
No plastics Has plastids — organelles that form pigments
Has cilla — hair like extrusions Mostly no cilla

1.3.2 Endosymbiotic theory

1.3.3 Organelles in Eukaryotic Cells

1.4 Cell Membrains

Eukaryotes have a thin membrane layer that helps them regulate nutrients, defend themselves, and control I/O. See KBhBIO101CellMembraines

1.5 Cell Replication

Eventually, at some point, cells need to replicate itself. This, of course, is due to the fact that your body needs to grow. This intricate process is dependent on KBhBIO101CentralDogma, specifically, KBhBIO101DNAReplication.

The timeschedule of each cell replicating is dependent on something called "The Cell Cycle". See KBhBIO101CellLifecycle
