Cell Structure
What is the basic unit of life?
What process do cells use to convert glucose into energy?
Cellular Respiration
What is a group of organisms of the same species living in the same area?
Population
What are the phases of mitosis?
The phases of mitosis are prophase, metaphase, anaphase, and telophase.
How much energy is typically transferred from one trophic level to the next?
10%
Which organelle is known as the powerhouse of the cell?
What is the mitochondria
What is the purpose of the cell cycle?
To allow for growth and reproduction of cells
What term describes the role an organism plays in its environment?
Niche
What is the process by which cells divide to produce new cells?
Mitosis
Explain the concept of carrying capacity in an ecosystem.
The maximum population size of a species that an environment can sustain indefinitely
What structure controls what enters and leaves the cell?
Cell Membrane
In which part of the cell does photosynthesis take place?
chloroplasts
What is the process by which plants make their own food using sunlight?
Photosynthesis
What are the three main stages of cellular respiration?
Glycolysis, Krebs cycle (Citric Acid Cycle), and Electron Transport Chain.
What role do decomposers play in an ecosystem?
Breaking down dead material and recycling nutrients?
What is the jelly-like substance inside the cell called?
Cytoplasm
What is the term for the movement of water across a semi-permeable membrane?
Osmosis
What term describes a community of living organisms and their physical environment interacting as a system?
Ecosystem
How does cytokinesis differ in plant and animal cells?
In animal cells, cytokinesis occurs through cleavage furrow formation, while in plant cells, a cell plate forms to separate the daughter cells.
How does a food web differ from a food chain?
A food web shows multiple feeding relationships, while a food chain shows a single pathway
What is the function of ribosomes in a cell?
Protein Synthesis
What is the role of enzymes in cellular processes?
they are catalysts that speed up chemical reactions
What is the impact of deforestation on biodiversity?
It decreases biodiversity by destroying habitats.
What are the differences between aerobic and anaerobic respiration?
Aerobic respiration requires oxygen and produces more ATP, while anaerobic respiration occurs without oxygen and produces less ATP, often resulting in lactic acid or alcohol as byproducts.
Explain the significance of the 10% rule in energy transfer.
it highlights that only a fraction of energy is passed on to the next level, limiting the number of trophic levels?
