What cells are the first respondents to injuries?
Platelets
What structure, present in both prokaryotic and eukaryotic cells, regulates the passage of substances into and out of the cell
The cell membrane
This organelle is the site of cellular respiration and is known as the powerhouse of the cell because it generates most of the cell's supply of adenosine triphosphate ATP, the main source of energy.
mitochondria
This general term refers to the movement of a substance across a cell membrane that does not require the cell to use energy ATP, such as diffusion or osmosis.
passive transport
what is OSMOSIS?
The movement of water.
What are the bodies general defense?
White Blood cells
These structures are found in the cytoplasm of both cell types and are responsible for protein synthesis
Ribosomes
These tiny structures, found in both prokaryotic and eukaryotic cells, are responsible for protein synthesis, following instructions from the nucleus.
ribosomes
This specific type of passive transport describes the diffusion of water molecules across a selectively permeable membrane from an area of higher water concentration to an area of lower water concentration.
osmosis
Osmosis is a specific type of this passive transport process, defined solely by the net movement of water molecules across a membrane.
diffusion
What does the plant need to gather for photosynthesis.
Carbon dioxide, Water, and sunlight.
A specialized, membrane-bound subunit with a specific function within a eukaryotic cell
An organelle
Found in eukaryotic cells, this large, membrane-bound organelle contains the cell's genetic material, or DNA, and controls the cell's activities, such as growth and metabolism.
nucleus
When a cell is placed in this type of solution, the net movement of water is out of the cell, causing the cell to shrivel or crenate because the solution has a higher solute concentration than the cell's interior.
hypertonic solution
For osmosis to occur, the boundary separating two solutions must be this type of membrane, meaning it allows certain molecules (like water) to pass through but restricts others
selectively permeable or semipermeable membrane
Where does the photosynthesis happen?
Chloroplasts
This entire category of organelles is notably absent in prokaryotic cells.
Membrane-bound organelles
In plant cells, this organelle captures light energy from the sun to produce food glucose through a process called photosynthesis, giving plants their green color.
chloroplast
This type of transport requires the cell to expend metabolic energy ATP to move substances, such as ions or large molecules, against their concentration gradient—from an area of lower concentration to an area of higher concentration.
active transport
This term describes a state where both the inside and outside of a cell have an equal concentration of water and solutes, resulting in no net water movement.
equilibrium
What energy does the plant create?
Glucose
The single most significant difference between these two cell types is the presence of a membrane-bound one of these
A nucleus
Sometimes called the suicide bag or the cell's recycling center, these organelles use digestive enzymes to break down waste materials, worn-out cell parts, and engulfed viruses or bacteria.
lysosomes
This specific mechanism of active transport uses a protein pump to move three sodium ions out of the cell for every two potassium ions moved into the cell, which is crucial for nerve impulses and muscle contractions.
sodium-potassium pump
Water or salt.
