Transcript of A Journey into the Plant Cell!

A Journey into the Plant Cell!
Tommy Martin

Plant Cell Organelles:
Kidney shaped organelles
Site of Cellular Respiration
“Powerhouse” of cell
RNA & protein; dispersed throughout cytoplasm or studded on Rough ER
Protein synthesis (make protein)
Smooth Endoplasmic Reticulum
Membranous network lacking ribosomes
Lipid (fats) & cholesterol synthesis
Rough Endoplasmic Reticulum
Membranous network studded with ribosomes
Protein synthesis.
Parts of a Plant Cell:
Cell Wall
The rigid structure that helps to support the cell.
Maintaining/determining cell shape
Economic products - cell walls are important for products such as paper, wood, fiber, energy, shelter, and even roughage in our diet.
Jelly-like fluid (70% water)
Suspends organelles in cell
This is where all of the chemical processes take place within the cell
Golgi Body
“Stack of Pancakes”
Packages proteins and carbs for "export" from the cell.
Modification, transport, and packaging of proteins
Capture the sun's light energy, and stores it while freeing oxygen from water.
They then use the energy to make organic molecules from carbon dioxide in a process known as the Calvin cycle. (Night time)
Bag of fluid inside the cell that gives it its support.
Cell Membrane
cell boundary
selectively permeable (controls what enters and leaves the cell; membrane transport)
1. Cell Wall
2. Cell Membrane
3. Cytoplasm
4. Nuclear Membrane
5. Nucleus
6. Nucleolus
7. Vacuole
8. Golgi Body
9. Cloroplast
10. Mitochondria
11. Ribosomes
12. Smooth ER
13. Rough ER
Nuclear Membrane
Serves as the physical barrier, separating the contents of the nucleus (DNA in particular) from the cytoplasm.
Central control center of cell
Houses DNA and proteins
Dense spherical body inside the nucleus
Makes ribosomes and protein (RNA)
RNA = ribonucleic acid, a nucleic acid present in all living cells. Its principal role is to act as a messenger carrying instructions from DNA for controlling the synthesis of proteins
