Transcript of Cell Structure and Function

Cell Structure and Function:
What are characteristics of eukaryotic cells?
Eukaryotic cells differ from each other depending on their structure and function.
A cell's
structure
is the arrangement of it's parts.
A cells
function
is the activity the parts carry out.
Parts that Protect and Support the Cell.
Cell Membrane
- acts as a barrier between the inside of the cell and the cell's environment.
Cytoplasm
- the substance that fills the region between the cell membrane and the nucleus.
Cytoskeleton
- a network of protein filaments that give shape and support to the cell.
Genetic Material in the Nucleus
Nucleus
- the organelle that contains a eukaryotic cell's Genetic material.

DNA- Deoxyribonucleic acid
- contains information needed to conduct cell processes like the production of proteins.
Mitochondria
mitochondria
- the organelles in a cell where cellular respiration occurs to release energy from compounds. They are responsible for transforming stored energy into usable ATP.
Ribosomes
Ribosomes
- the organelle that makes proteins by putting together chains of amino acids using instructions encoded in the cell's DNA.
In this section we will discuss what types of organelles exist inside eukaryotic cells and what the function is of each one. We will also discuss what the differences are between animal and plant cells.
Endoplasmic Reticulum
Golgi Complex
The Plant Cell
Animal Cells
E.R.
- a system of membranes close to the nucleus that assists in the production, processing, and transport of proteins and in the production of lipids.
Golgi Complex
- a membrane bound organelle that packages and distributes materials such as proteins.
Cell Wall
- a rigid structure that surrounds the the cell membrane. They provide support and protection for the cell.

Large Central Vacuole
- a large fluid filled vesicle that stores enzymes, nutrients, water, and/or wastes.

Chloroplasts
- organelles where photosynthesis occurs. Photosynthesis is the process by which cells use sunlight, carbon dioxide, and water to make sugar and oxygen.
Lysosomes
- contain digestive enzymes which break down worn-out or damaged organelles, waste materials, and foreign invaders in the cell.
