Cell Organelles/Theory
Which organelle is the control center of the cell? It looks like a large circle in the center of the cell.
The Nucleus
Osmosis
Metaphase
What is the name of the organelle where photosynthesis takes place in plant cells?
Chloroplast
What word do we use to describe humans burning fossil fuels that releases carbon dioxide (CO2) into the air?
Combustion
Which 2 organelles are ONLY FOUND in PLANT cells but NOT in animal cells?
Chloroplast and the Cell Wall
All substances naturally flow from _______ to ______ concentration.
High to Low Concentration
Mitosis is known as __________ reproduction that creates gametes like sperm and egg whereas mitosis is known as ___________ reproduction that creates body cells like skin/muscle cells.
Sexual, Asexual
Name the 2 reactants (ingredients) of cellular respiration.
Oxygen and Glucose
What 2 processes do LIVING things contribute to the carbon cycle?
Photosynthesis & Respiration
What are the 3 parts of the cell theory?
2. Cells are the most basic (smallest) unit of life
3. All cells come from pre-existing cells
Which 2 are examples of passive diffusion?
Diffusion
Active Transport
Photosynthesis
Osmosis
Diffusion & Osmosis
Cytokinesis
Name the 3 reactants of photosynthesis.
CO2 (carbon dioxide) + H2O (water) + sunlight
Gas to a Solid
What organelles do ALL cells have (regardless of plant/animal)? Name at least 4.
Ribosomes
Cytoplasm
Nucleus
Mitochondria
ER
Golgi Apparatus/Body
Explain the difference between osmosis and diffusion.
Osmosis describes the flow of water whereas diffusion describes the flow of all other substances from high to low concentration.
Name the 4 stages of mitosis and put them in the correct order.
Prophase, Metaphase, Anaphase, & Telophase
What do animals produce that plants need to survive? (need to list 2 things)
CO2 + H2O
What are the 4 main parts of the water cycle?
Evaporation, Condensation, Precipitation, Transpiration
List the following in ORDER from smallest to largest: organ system, cells, organism, tissue, organs
Cells, tissues, organs, organ systems, organisms
There is a higher concentration of water OUTSIDE of a cell than inside. In this situation, is the water going to flow INTO or OUT OF the cell? Which organelle is the water passing through? Explain.
The water will flow INTO the cell BECAUSE substances always naturally flow from a higher concentration to a lower concentration. So, the water would flow from the HIGHER concentration OUTSIDE the cell towards the LOWER concentration INSIDE the cell. It is passing through the cell membrane.
Compare and contrast mitosis and meiosis in terms of:
- The number of daughter cells they make
- The number of chromosomes their daughter cells have compared with the original cell
- Whether they are genetically-identical or different
Mitosis makes 2 genetically-identical daughter cells with the same number of chromosomes as the parent cell.
Meiosis makes 4 genetically-different daughter cells with half the number of chromosomes of the parent cell.
Tell me whether producers or consumers can perform photosynthesis, and tell me what is the source of all energy for food webs on land?
Only producers can perform photosynthesis, and the sun is the source of all energy.
Look at the food chain below:
Grass ----> Rabbit ---> Snake ---> Hawk
If the snakes are killed off by human pollution, explain what will happen to the rabbit population.
They will increase because they have fewer predators.
