Cells

A Review

Cells that have a Nucleus.

Cells that have Membrane-bound Organelles.

​Eukaryotic

Cells that Do Not have a Nucleus or Membrane-bound Organelles.

​Prokaryotic

Two Types Of Cells

• Protists

• Fungi

• Animals

• Plants

​Eukaryotic

• Bacteria

• Round irregular shape

• One of more Small Vacuole

• Centriole

• Cytoplasm

• Ribosomes

• Mitochondria

• Endoplasmic Reticulum

• Peroxisomes

• ​Golgi Apparatus

• Plasma Membrane (only cell membrane)

• Microtubules

• Flagella (only in some cells)

• Lysosomes (occur in the cytoplasm)

• Cilia

​ANIMAL CELLS HAVE:

PLANT CELLS HAVE:

• Endoplasmic Reticulum

• Peroxisomes

• Golgi Apparatus

• Plasma Membrane (cell membrane and cell wall)

• Microtubules

• Flagella ( found in some plant cells)

• Nucleus

• Cells Wall

• One large central Vacuole

• Centrioles (only in lower plant forms)

• Chloroplast

• Cytoplasm

• Ribosomes

• Mitochondria

• Plastids

​Organelles

• Organelles are tiny organs in cells.

• As you can see from the last two slides, both animal and plant cells contain many organelles.

• The organelles each have their own job to do.

Living organisms develop from non-living matter.

​Spontaneous Cell Generation

All cells are created by other living cells. Therefore all life is formed by other living cells.
