Cell Organelles
What controls what enters and leaves the cell?
Cell membrane
What is the movement of particles from high to low concentration?
Diffusion
What macromolecule includes sugars and starches?
Carbohydrates
What does homeostasis mean?
Maintaining stable internal conditions
Which organelle makes proteins?
Ribosomes
Which organelle produces energy for the cell?
Mitochondria
What is the movement of water across a selectively permeable membrane?
Osmosis
Which macromolecule is important for long-term energy storage?
Lipids
Why does a cell need homeostasis?
To keep conditions stable so it can function properly
Which transport process requires energy?
Active transport
What is the jelly-like material inside the cell?
Cytoplasm
What type of transport uses membrane proteins but does NOT require energy?
FACILITATED DIFFUSION
Which macromolecule builds and repairs structures in cells?
Proteins
How can cell transport help maintain homeostasis?
It controls the movement of materials into and out of the cell
A substance moves from low concentration to high concentration. What process is this?
Active transport
Which organelle stores water and other materials?
Vacuole
What is the difference between passive and active transport?
Passive transport does not require energy while active transport does
Which macromolecule contains DNA and RNA?
Nucleic acids
What could happen if a cell cannot maintain homeostasis?
The cell may stop functioning properly
Facilitated diffusion
What structure provides support and protection around a plant cell?
Cell Wall
Which transport process moves water?
Osmosis
Name ALL four major macromolecules.
Carbohydrates, lipids, proteins, nucleic acids
How do the cell membrane and transport processes work together to maintain homeostasis?
They regulate what enters and leaves the cell helping keep internal conditions stable
A cell needs to move a substance from low concentration to high concentration. Does it need energy?
Yes active transport requires energy (ATP)
