Transcript Type of Cell Diversity

Cell Diversity
Fibroblasts – found in connective tissues which help
protect, support and bind together other tissue types.
They have rough ER and Golgi apparatus to make
and secrete proteins needed for their fibers.
Erythrocytes – red blood cells which carry oxygen in the
bloodstream (no organelles so it has more room to
carry oxygen)
Cell Diversity
Epithelial Cells – their shape allow cells to be packed
together like sheets which cover and line
body organs. Has long protein-fibers to resist
tearing when it gets rubbed or pulled.
Cell Diversity
Skeletal Muscle – elongated shape which allow cells to
shorten (contract) moving our skeleton. They
contain long protein fibers.
Smooth Muscle – elongated shape too which allow our
internal organs to change size
Cell Diversity
Fat cell – huge spherical shaped cell which is formed
because of the large fat droplet in its cytoplasm.
Stores nutrients along with fat.
Cell Diversity
Macrophage – this cell can change shape so it can crawl
through tissue to reach infection sites. They contain
many lysosomes to digest infectious microorganisms.
Cell Diversity
Nerve Cell (called neuron) – cell has long extensions that
receive and transmits messages to other body parts.
Long plasma membrane and a lot of rough ER to
make proteins needed for the membrane.
Cell Diversity
Oocyte (female) – the largest cell in the body. This cell has
twice as many organelles so it can distribute to new
cells through growth/division.
Sperm (male) – This cell is long and built for swimming.
Flagellum acts as a whip to move sperm forward.
