Ecosystems & Biomes
These are the living organisms that influence or shape an enviornment
What are Biotic Factors
This plant structure is the main site of photosynthesis
What are the leaves
This tissue transports water and minerals upward from the roots
What is xylem
These cells contain membrane-bound organelles and are generally larger and more complex.
What are eukaryotic cells
This organism obtains energy and nutrients by consuming plants
What is a herbivore
Sunlight, temperature, water, air, and soil are examples of these
What are abiotic factors
This structure provides support and contains parts that move water, minerals, and sugar throughout the plant
What is the stem
These tiny microscopic pores are found on the underside of leaves and open and close
What are stomata
These cells lack membrane-bound organelles but contain DNA and ribosomes.
What are prokaryotic cells
This is a straight pathway showing how energy moves from one living organism to another when eaten.
What is a food chain
This type of large global region is defined by its biotic and abiotic factors.
What is a biome
These structures help secure the plant and allow it to access water and materials in the soil.
What are the roots
⭐ DOUBLE JEOPARDY
A student observes that a plant's leaves are producing sugars, while the roots are absorbing water and minerals.
Identify BOTH plant transport tissues involved and explain what each one transports.
Xylem transports water and minerals upward from the roots.
Phloem transports sugars/food up and down the plant.
This organelle stores and guards genetic information
What is the nucleus
This is a large interconnected group of many food chains within one ecosystem
What is a food web
This biome can be either warm or cold, is defined by dryness, and contains organisms adapted to surviving with little water.
What is the desert biome
Unlike roots and stems, this plant structure contains the microscopic pores responsible for gas exchange
What are the stomata in leaves
Name the three major functions of stomata identified in the slides.
What are gas exchange, water control, and transpiration
This organelle modifies, sorts, and ships proteins
What is the Golgi apparatus
⭐ DOUBLE JEOPARDY
An ecosystem experiences a severe natural disaster that destroys shelter and reduces available food and water.
Using the definition of limiting factors, explain why this single event could affect multiple populations within the ecosystem.
Natural disasters can act as limiting factors. Because the disaster can reduce food, water, shelter, and/or space, multiple populations can experience reduced growth or development and changes in population size.
A region is warm and wet, lies near the equator, and contains extremely high biological diversity. Based on the characteristics in the slides, identify the biome.
What is the tropical rainforest
A student says, “The roots are the part of the plant responsible for photosynthesis because they absorb the materials plants need.” According to the slides, what is wrong with this statement?
The leaves are the main site of photosynthesis. Roots primarily help secure the plant and access materials in the soil.
A plant's roots have successfully absorbed water, but the tissue responsible for moving that water upward through the plant is damaged. Identify the tissue and explain what material it normally transports.
What is xylem, which transports water and minerals upward from the roots
A mystery cell contains DNA and ribosomes but lacks membrane-bound organelles. Based only on the characteristics presented in the slides, what type of cell is it?
What is a prokaryotic cell
Consider this chain: Grass → Rabbit → Wolf. A major decrease in available grass occurs. Using the concepts from the slides, explain how this abiotic/biotic change could eventually influence organisms farther along the food relationship.
A decrease in grass reduces the food available to rabbits, which can reduce the rabbit population or limit its growth. With fewer rabbits available as prey, wolves could also be affected. This demonstrates how organisms in a food chain are interconnected.
