What is reproduction?
What gas do plants take in to produce food?
What is carbon dioxide?
The plasma membrane regulates the transportation of substances in and out of the cell, demonstrating selective permeability.
Cell Membrane
a barrier that lets some molecules or ions pass through while blocking others
What is semipermeable membrane?
Organ systems working together in one individual.
What is an organism?
They detect and react to changes in their environment (e.g., light, touch, temperature).
What is a stimulus?
Name two organelles that exist only in plant cells.
Cell Wall, Central Vacuole, Chloroplast
Site of photosynthesis, converting light into energy.
Chloroplast
Water moves across the membrane from an area of higher water concentration to lower concentration, a key process in cells.
What is osmosis?
Give an example of an organ?
What is lung, brain, heart, kidney, stomach, etc...?
They eliminate waste products.
What is Excretion?
Organisms that are often visible through naked eyes.
Multicellular organisms
Storage sacs (large in plants for water, nutrients).
Vacuole
Factors in an environment that are not living.
What are abiotic?
The natural, passive movement of particles from an area of high concentrated to an area of low concentration.
What is diffusion?
Populations evolve over time, developing traits that help them survive in their environment.
Adaptation
2 types of Adaptation
Physical and Behavioral
The "powerhouses," generating most of the cell's energy (ATP)
Mitochondria
Tiny, hair-like projections on intestinal cells that increase the surface area for nutrient absorption, forming the "brush border" on the villi.
Microvilli
What is tissue?
