|
Name the parts of the mitochondria |
Christae, Outer Membrane, inner membrane, Matrix |
|
|
Name the parts of the chloroplast |
Chlorophyll, Granum, Thilacoid, Stroma, Lamella |
|
|
Describe the structure of Actin filament |
Like 2 pearl necklaces twisted together, each pearl being a protein molecule |
|
|
What are ribosomes and where are they located? |
They are found on the endoplasmic reticulum near the nucleus and are used to create protein parts. |
|
|
What does the golgi body do and describe it's structure. |
It is flattened sacuoles that are used to put together protein parts and ship them using vesicles. |
|
|
How are vacuoles made? |
A large number of vesicles combine to make a vacuole |
|
|
Name the 5 functions of the cell membrane |
Separate inside and outside of cell, provide shape, cell identification, receive hormone messages, and transport waste and nutrients |
|
|
Describe the structure of plasma membrane |
It is a phospbolipid bilayer with proteins scattered throughout |
|
|
Describe a function of a lysosome |
Used to recycle. Protein parts, can expand to kill the cell, used to break down proteins |
|
|
Describe structure turn of an intermediate filament |
Many microfiliments twisted together like string in a rope |
|
|
What does a basal body do |
It migrates to the edge of a cell and creates cilia or flag ella |
|
|
What is the formation of cilia |
9 plus 2 pattern of mixrotubule pairs, 2 in the middle are connected by spokes to the outer 9 pairs. |
|
|
Describe the structure of microtubule |
Paired protein molecules that create a hollow cylinder like a slinky. |
|
|
What does the MTOC do |
Assembles or disassembles microtubules to move organelles, and creates centrioles, and basal bodies. |
|
|
What is the formation of centrioles |
A 9 plus 0 hollow cylinder of triplets |
|
|
What happens in the mitochondria |
Cellular respiration. Glucose and oxygen are broken down into carbon dioxide and water releasing ATP energy. |
|
|
What happens in the chloroplast |
Photosynthesis. Uv energy I'd used to react carbon dioxide and water to create glucose and oxygen |
|
|
What is a peroxisome |
A lysisome used to break down fats, when it does so it gives off H2O2 as a waste. |
|
|
Is photosynthesis endothermic or exothermic. |
It is endothermic it's taking in the UV energy |
|
|
What is a function of the cytoskeleton |
It provides shape, protection and locomotion to the cell |
|
|
Ehat are the 3 parts of the cytoskeleton |
Actin filament, intermediate filament microtubules |
|
|
Why can't cells be very big? |
The surface area grows more slowly than the volume, so it can't properly remove waste and bring in nutrients very fast. This leads to the cell both starving and poisoning itself. It then must divide it die. |
