Cell Biology
What's the key difference between prokaryotic and eukaryotic cells
The key difference between prokaryotic and eukaryotic cells is the presence of a membrane-bound nucleus and membrane-bound organelles in eukaryotic cells, which prokaryotic cells lack.
What's Diffusion
Diffusion is the movement of particles from an area of high concentration to an area of low concentration.
What is Ecology?
Ecology is the study of the relationships between organisms and their environment.
Where is DNA found?
DNA is found in the nucleus of eukaryotic cells and in the nucleoid region of prokaryotic cells.
"What are the specific structural differences between plant and animal cells that lead to the argument that plant cells are more complex?"
Claim: Plant cells have more complex structure than animal cells.
What organelles are found in both plant and animal cells
Three organelles found in both plant and animal cells are mitochondria, endoplasmic reticulum, and the Golgi apparatus.
What's Osmosis
Osmosis is the diffusion of water across a semipermeable membrane from a region of low solute concentration to a region of high solute concentration.
What is a population
A population is a group of individuals of the same species in a given area, a community is different populations interacting, and an ecosystem is a community and its physical environment.
What are the two forms of DNA in a cell, and when are they visible
Chromosomes are condensed forms of DNA visible during cell division, while chromatin is the less condensed form present during interphase.
"What unique structures do plant cells possess that animal cells lack?"
Plant cells possess a cell wall, chloroplasts, and a large central vacuole which animal cells lack.
What does the cell membrane regulate
The cell membrane regulates the passage of substances in and out of the cell, protects the cell, and maintains its shape.
What's Homeostasis
Homeostasis is the maintenance of a stable internal environment within an organism.
What are the three main types of symbiotic relationships, and how does each type affect the organisms involved?
The three types of symbiotic relationships are mutualism (both benefit), commensalism (one benefits, the other is unaffected), and parasitism (one benefits, the other is harmed).
What are the four phases of mitosis?
The four phases of mitosis are prophase, metaphase, anaphase, and telophase.
What structures in plant cells enable them to perform photosynthesis and provide structural support?
These structures give plant cells specialized functions like photosynthesis and structural support.
What are the key structural differences between plant and animal cells, and which structures are found in plant cells but not in animal cells?
Plant cells have a cell wall, chloroplasts, and a large central vacuole, while animal cells lack these structures.
What's Dynamic equilibrium? Example?
Dynamic equilibrium is a state of balance where opposing processes occur at equal rates, resulting in no net change. An example is the body maintaining a constant internal temperature.
What's Predation. Example
Predation is when one organism (predator) kills and consumes another organism (prey). An example is a lion preying on a zebra.`
What is cytokinesis and what is its role in cell division?
Cytokinesis is the division of the cytoplasm and organelles after mitosis, resulting in two daughter cells.
Which plant cell structure is responsible for both photosynthesis and the formation of cell walls
chloroplast and the cell wall, although the question focuses on a single structure for conciseness.
What does the endosymbiotic theory propose regarding the origin of mitochondria and chloroplasts.
The endosymbiotic theory proposes that mitochondria and chloroplasts originated from prokaryotic cells that were engulfed by early eukaryotic cells, says the National Institutes of Health (NIH) (.gov).
What is Solute and what does it do?
Solute is a substance that dissolves in a solvent, solvent is the substance that dissolves the solute, and solution is the mixture of solute and solvent.
What process describes the continuous movement of carbon through the Earth's systems, and why is this movement crucial for life on Earth?
The carbon cycle describes how carbon moves through the Earth's systems. It's important for life because carbon is a fundamental building block of organic molecules.
What role does the centromere play in mitosis?
Centromeres hold sister chromatids together. They also serve as attachment sites for spindle fibers during mitosis.
What specific features of plant cells demonstrate a more complex internal structure compared to animal cells, particularly regarding their organelles and organization?
Plant cells exhibit a more complex internal structure than animal cells, particularly in their organization and specialization of organelles.
