Cell Membrane & Transport
This thin structure forms the flexible boundary around a cell and controls what enters and leaves it.
What is the cell membrane?
Particles spread from an area where there are many of them to an area where there are fewer. This process is called this.
What is diffusion?
Plants use this process to make their own food using light energy.
What is photosynthesis?
This repeating series of events includes cell growth, preparation for division, and cell division.
What is the cell cycle?
This process explains why, when the teacher sprays air freshener on one side of a classroom, after a while, students across the room can smell it.
This membrane property allows some substances to pass through while limiting or blocking others.
What is selective permeability?
During diffusion, particles have a net movement toward an area with this concentration.
What is lower concentration?
This organelle in plant cells is where photosynthesis takes place.
What are chloroplast?
During this part of the cell cycle, the cell grows, carries out normal activities, and prepares to divide.
What is interphase?
A plant needs light energy to make glucose. This cell process allows the plant to do that.
What is photosynthesis?
This type of transport does not require the cell to use energy.
What is passive transport?
Diffusion belongs to this category of transport because it does not require cellular energy.
What is passive transport?
This green pigment in chloroplast captures light energy.
What is chlorophyll?
During this stage, the nucleus divides so each new cell can receive a complete set of genetic material.
What is mitosis?
A scraped knee heals as body cells make more cells. This process makes growth and repair possible.
What is cell division?
This type of transport requires the cell to use energy to move materials across its membrane.
What is active transport?
This structure acts like a gatekeeper by controlling which materials can enter or leave the cell.
What is the cell membrane?
Plants take in this gas from the air to help make food during photosynthesis.
What is carbon dioxide?
This stage divides the cytoplasm and finishes the formation of two new cells.
What is cytokinesis?
A cell has finished interphase and is ready for its nucleus to divide. This stage comes next.
What is mitosis?
This internal stable environment is disrupted when a cell’s membrane stops controlling what enters and leaves the cell.
What is homeostasis?
This specific type of diffusion involves water moving across a selectively permeable membrane.
What is osmosis?
This simple sugar is produced during photosynthesis and stores chemical energy for the cell.
What is glucose?
The two new cells produced after one parent cell divides are called these.
What are daughter cells?
A plant cell must make food and later produce new cells for growth. These two Chapter 3 processes make those jobs possible.
What are photosynthesis and cell division?
