Organelles!
This organelle is the outer membrane that protects the cell.
Cell Membrane
This is the smallest unit of organization in a ecosystem.
An organism
What is the defining feature of a prokaryotic cell? Give one example
Prokaryotes do not have a nucleus. Bacteria
What is a Eukaryote?
An organism whose cells contain a nucleus.
What is bioengineering? Give an example of a product of bioengineering.
Applying engineering or technology to living systems. Pacemaker.
This is the powerhouse of the cell.
Mitochondria
This part of the earth system includes all the biotic and abiotic factors.
Ecosystem
Would you expect more nerve cells to be present in the skin or in the muscle? Why?
There is likely to be more nerve cells on the skin because the skin is more likely to need to send sensory information to the brain.
What is an abiotic factor? Give two examples.
Nonliving components of an ecosystem.
Humans undergo thermoregulation to maintain a constant body temperature. What would the stimulus be in the process of thermoregulation? What is a physiological response to the stimulus?
Hot weather --> sweating
This is an organelle that is unique to plants and stores water.
Vacuole
What is the difference between a community and a population?
Community = multiple species of organisms
The cell walls of plant cells have openings or channels. How is this structure most likely related to the proper functioning of the plant system?
The plant may need to send nutrients and water between cells, so the channels allow these to pass through.
What is a stimulus?
An action that causes an imbalance in the internal conditions of the organism which results in a physiological response.
Producers gain their energy from the sunlight through photosynthesis. Where do consumers get their energy? If this amount of energy proportional (similar) to that gained by the producers?
Consumers get their energy from the producers. There is somewhat less energy gained from the consumers than the consumers gain from the sun.
This organelle finishes protein assembly, mainly for membrane bound proteins.
Which of the component of the biosphere connect all three?
Hydrosphere.
If a plant wilts, which organelle is likely involved in the shriveling? Why?
Vacuole.
What is cell differentiation?
The process by which unspecialized cells develop into their mature form and function.
What would happen on a hot summer day if your brain did not receive input that your body was starting to heat up?
You would not feel any effect at all.
This organelle carries out photosynthesis.
Chloroplast
1. Made of cells
2. Growth/change over time
3. Require an energy source
4. Reproduce
5. Maintain homeostasis
Red blood cells carry oxygen to cells. To carry out their function, these cells must bind oxygen and travel through small blood vessels in the circulatory system called capillaries. Capillaries are so narrow that red blood cells must move through single file. How does the structure of a red blood cell allow them to carry out their function?
They are small and disc shaped, this allows them to fit through the circular channels inside a capillary
A group of cells that work together to perform a similar function.
The stomata (or stoma) in plants open and close to keep water loss under control and allow gas exchange in the plant. Would you expect a plant found in the desert to have many stoma?
No, to prevent water loss the plant would have fewer stoma.
