2: Cell Structure

What 3 things do all cells have in common?

All cells have a plasma membrane, cytoplasm, and genetic material (DNA).

Eukaryotic Cells

are complex cells with a membrane-bound nucleus and organelles, including mitochondria and the endoplasmic reticulum. They can be unicellular or multicellular.

where are eukaryotic cells found

in animals, plants, fungi

where are prokaryotic cells found

in bacteria and archaea.

prokaryotic cells

are simpler, smaller cells lacking a membrane-bound nucleus and organelles and are typically unicellular. but have genetic material - always one cell

nucleus

contains DNA, genetic material - ditates what the cell is going to do

chromatin

form of dna found in nuclear membranec

chromosomes

condensed dna, stores and organizes gentic instructions (genes) used for cell growth

nucleolus

structure where ribosomes are made. found in the nucleus

ribosomes

• cellular structure that leaves nucleus

• synthesizes and makes proteins

• ribosomes and organelles float around the cytoplasm

  • can be found around cytoplasm or sticking onto the rough ER

endoplasmic reticulum

network of membrane-enclosed sac and branching tubules found in cytoplasm of eukaryotic cells

rough er

smooth er

golgi apparatus

lysosome

mitochondrion

cellular respiration

cytoskeleton

microtubules

chloroplast

chlorophyll

cell wall
