Odds and Ends
A solution in which the concentration of solutes is lower relative to another solution.
What is hypotonic solution?
This chemical process occurs in the mitochondria.
What is cellular respiration?
This organelle contains its own DNA.
What is the mitochondria?
the movement of particles from areas of greater concentration to areas of lesser concentration
What is diffusion?
These plastid contain green pigment and chlorophyll, and are used in photosynthesis.
What are chloroplasts?
____________________ cells have cell membranes, cytoplasm, and ribosomes, will grow and reproduce but do NOT have a nucleus.
Prokaryotic
The rupturing of a cell due to excess internal pressure.
What is cytolysis?
These digestive organelles also serve to break up dead cell material.
What are lysosomes?
Movement of molecules through the plasma membrane aided by a process that requires energy.
active transport
Plastids containing yellow, orange, or red pigments used in photosynthesis
Chromoplasts
What is the function of the mitochondria?
The powerhouse of the cell, the mitochondria, is where nutrients are converted to ENERGY
Endocytic process in which a cell engulfs large particles or whole cells.
What is phagocytosis?
These membrane-bound sacs transport large molecules through membranes.
What are endocytic vesicles?
1. The release of substances out of a cell by the fusion of a vesicle with the membrane (active transport).
2. A process that moves particles into the cell by vesicles forming from the cell membrane (active transport).
1. What is exocytosis?
2. What is endocytosis?
Leucoplasts are a plastid that is non- and stores .
Leucoplasts are a plastid that is non-pigmented and stores carbohydrates.
What cellular activity cannot occur in a cell without energy? What cellular activity can still occur without energy?
Active transport cannot occur without energy. Diffusion and Osmosis, which are passive processes, can still occur because they do not require energy.
When a cell releases protein into the extracellular fluid
What is secretion?
Ribosomes are the site
of .
Ribosomes are the site of protein synthesis.
Cytoplasmic streaming is the motion of
in a cell that results in a
movement of the
cell's .
Cytoplasmic streaming is the motion of cytoplasm in a cell that results in a coordinated movement of the cell's contents.
STUDY Figure 4.14 of the Plasma Membrane and Figure 4.15 of the Phospholipid on page 158.
In Figure 4.14, be able to identify: Carbohydrate, Cholesterol, Glycolipid, and Channel Protein
In Figure 4.15, be able to identify: Hydrophilic Phosphate Head and Hydrophobic Fatty Acid Tail
What are the 3 main ideas of cell theory?
1. All living things are made of cells.
2. The cell is the basic unit of structure and function of life.
3. All cells come from other cells.
Plasmolysis refers to the collapse of a walled cell's
due to a lack of .
Plasmolysis refers to the collapse of a walled cell's cytoplasm due to a lack of water.
Name the scientists that contributed to cell theory.
What is Hook, Schwann, Schleiden, and Virchow?
What are 3 forms of PASSIVE transport, and how are they different from ACTIVE transport?
Diffusion, facilitated diffusion, and osmosis.
These require NO energy and move molecules with their concentration gradient (high to low)
