Cell Structures
What is the basic unit of life?
The basic unit of life is the cell.
What is the difference between diffusion and osmosis?
Diffusion is the movement of any substance from an area of high concentration to low concentration, while osmosis is specifically the diffusion of water across a semipermeable membrane.
In an ecosystem what is the difference between biotic and abiotic components?
Biotic are living while abiotic are nonliving.
What is the longest phase of mitosis?
INTERPHASE.
What is the Claim?
Claim: Commensalism is a relationship between two organisms where one animal benefits, while the other animal is unaffected.
What are the two main types of cells and how do they differ?
The two main types of cells are prokaryotic and eukaryotic cells.
Which factors would increase the rate of diffusion?
Increased temperature and a larger surface area both increase the rate of diffusion.
What kind of animal would pursue another animal for food?
What is a predator.
What hold the spindle fibers in place.
Centrioles.
What is the evidence?
Evidence: Commensalism is portrayed when a bird builds it’s nest in a tree, The bird is benefited by having somewhere safe and sturdy to build its home and the tree is not affected in any way.
What is the function of the cell membrane and how does it help the cell?
Its primary functions include regulating the movement of substances into and out of the cell, providing structural support, and facilitating communication with other cells.
How does osmosis play a role in how plants absorb water from the soil?
Water moves from the soil, which has a higher water potential, into the plant's cells through osmosis, following the movement of water from an area of high concentration to low concentration across a semipermeable membrane.
What is a relationship in which both organisms benefit?
Mutualism
In what phases of mitosis is there no nucleus?
In metaphase, telophase, and anaphase.
What is the evidence
Evidence: Commensalism is portrayed when a bird builds it’s nest in a tree, The bird is benefited by having somewhere safe and sturdy to build its home and the tree is not affected in any way.
What are the key differences between plant and animal cells in terms of their structure and function?
Plant cells possess a cell wall, chloroplasts, and a large central vacuole, while animal cells lack these structures and have lysosomes and centrosomes.
Describe what happens to a cell if it is placed in a hypertonic solution (a solution with a higher solute concentration than the cell).
Water will move out of the cell into the surrounding solution via osmosis, causing the cell to shrink or shrivel.
What are four things organisms might compete for?
Food, water, shelter, or mate.
In interphase the DNA is in the form of loose threads called what?
Chromatin.
What is the reasoning?
Reasoning: Commensalism is seen when one animal benefits off of another animal that is not affected.
How do organelles like mitochondria and chloroplasts contribute to the overall function of a cell, and how does their structure relate to their function?
Their structures are intricately linked to these functions, with features like folded membranes in mitochondria maximizing surface area for energy production and specialized compartments in chloroplasts optimizing light absorption and sugar production.
How would you design an experiment to demonstrate the effect of different sugar concentrations on osmosis?
You could use potato slices or strips, and measure their weight or volume before and after soaking in different sugar solutions (e.g., distilled water, 10% sugar solution, 20% sugar solution) for a set amount of time.
What is another term for an ecosystem?
What is a biological community.
When does the cytoplasm split into two new daughter cells.
In Cytokinesis.
What is the reasoning?
Reasoning: Commensalism is seen when one animal benefits off of another animal that is not affected.
