1: What is homeostasis?
When internal condition are not stable
When internal conditions are stable
2: What are five ways materials can move across the cell membrane?
Homeostasis, photosynthesis, passive transport, active transport
Osmosis, Homeostasis, Passive transport, Active transport
Lipid Diffusion, Osmosis, Passive Transport, Active Transport, Vesicles
3: What is Plasmolysis?
The growth of cells
Makes proteins
Shrinkage or contraction of the protoplasm away from the wall of a living plant or bacterial cell, caused by loss of water through osmosis.
4: What is this?
SER
Vacuole
Cytoskeleton
Golgi
5: What is this?
Vacuole
Nucleus
Cytoskeleton
RER
6: What is Active transport?
When molecules move down in concentration rate
A kind of transport wherein ions or molecules move against a concentration gradient, which means movement in the direction opposite that of diffusion – or – movement from an area of lower concentration to an area of higher concentration.
7: Examples of ions
Cl, N, C, H
Na,Cl, K, Ca2
8: What is osmosis?
Is when the process in which fluid Does not pass through
Osmosis is a process in which a fluid passes through a semipermeable membrane, moving from an area in which a solute such as salt is present in low concentrations to an area in which the solute is present
9: Give an example of diffusion
Water
Perfume
10: What is osmosis?
Is when the process in which fluid Does not pass through
Osmosis is a process in which a fluid passes through a semipermeable membrane, moving from an area in which a solute such as salt is present in low concentrations to an area in which the solute is present
11: Give an example of diffusion?
Water
Perfume
12: What is diffusion?
The active movement of molecules along the concentration gradient
The passive movement of molecules or particles along a concentration gradient, or from regions of higher to regions of lower concentration.
13: List four types of passive transport
Osmosis, facilitated, mitochondria, proteins
Diffusion, osmosis, Facilitated, ion channel
14: What is this?
Rough ER
Smooth ER
15: What is this?
Rough ER
Smooth ER
16: What cytolysis
Results in making proteins
Cytolysis is a cell death which occurs as the result of a rupture in the cell's membrane
17: What is hypotonic environment?
Having a lower degree of tension in an area
Having a greater degree of tone or tension in an area
18: What way water move in hypotonic environment?
Low water ->high water
High water -> low water
19: What is facilitated diffusion?
Is an active transport that does not let substance pass through the membrane
Facilitated diffusion is a type of passive transport that allows substances to cross membranes with the assistance of special transport proteins.
20: What determines water movement during osmosis?
The concentration
Diffusion
21: Is facilitated diffusion passive or active transport?
Active transport
Passive transport
22: What is isotonic environment?
Pertains to a muscular contraction in which the muscle remains to be in a relatively constant tension while its length changes, as in isotonic muscle.
High concentration
