Two types of cells
0 Prokaryotic
0 Eukaryotic
Prokaryotic cells
Prokaryotic Cells
0 Single Celled
0 Lacks a nucleus
0 Smallest and most simplest cells
0 Ex: Bacteria
Parts
0 Cell Wall: Outer surrounding of the cell- protects from
environment
0 Cell Membrane- double- layer of phosoplipids &
proteins - essentially the “bag” that holds it together
0 Ribosome: where proteins are made
0 Flagellum- used for locomotion
0 Pili- hairlike appendage found on the surface of many
bacteria.
0 Cytoplasm- Gel-like fluid
Eukaryotic Cells
Two Types
1. Animal Cells
2. Plant Cells
Cell Parts and Functions
Cell Membrane
Protects the cell
Lets things in and out of the cell
Location: around the cell
Nucleus
Control center
Location: inside the cell,
near the center
Cell Parts and Functions
Nucleolus (Nucleoli)
Makes ribosomes
Location: inside the nucleus
(dark spot)
Nuclear Membrane
Protects nucleus
Lets things in/out of nucleus (pores)
Location: around nucleus
cell
Cell Parts and Functions
Mitochondria
Makes energy/powerhouse
Location: in cytoplasm
Golgi Bodies/Apparatus
Packages and secretes
(gets rid of) waste
Location: in cytoplasm
Mitochondria
GOLGI APPARATUS
Cell Parts and Functions
Endoplasmic Reticulum (E.R.)
Transports materials and sends messages to all parts
of the cell
Two types: smooth and rough (has ribosomes)
Location: attaches from cell membrane to nuclear
membrane
Rough E.R.
Cell Parts and Functions
Ribosome
Makes proteins
Location: in cytoplasm or
Attached to E.R.
Vacuole
Stores food and water
Location: in cytoplasm
Vacuole
Cell Parts and Functions
Lysosome
Contains digestive enzymes
Destroys bacteria, old cell parts…
Location: in cytoplasm
Centrioles
Helps the cell to divide
Location: in cytoplasm
Cell Parts and Functions
Cytoplasm
Gel-like substances, holds all
Organelles in cell
Location: in cell
Chromatin/Chromosomes
Contains genetic information/traits
Location: in nucleus
Cell Parts and Functions
Cilia
Short hair-like projections
Used for movement
Location: outside of cell
Flagella
Long whip-like tail
Used for movement
Location: outside of cell
FLAGELLA
Cell Structures and
Chloroplast
Functions
Traps suns energy and
Makes food
Location: in plant cells
Cell Wall
Cell Wall
Protects and supports plant
Cells
Prevents water loss
Cellulose
Location: outer layer of plant
cells
CYTOSKELETON
Function: Support structure of cell and
transport materials/organelles throughout
the cell.
The highway of the cell.
Made of Microtubules (thin hollow
cylinders) and Microfilaments (thin solid
cylinders)
Location: Inside the cell
CYTOSKELETON
Cell Structures and Functions
Plastids
Stores extra food in
Plant cells
Location: in plant cell
