The basic unit of structure and function in living things.
What is a cell?
This is a tiny cell structure that carries out a specific function within the cell.
What is an organelle?
This organelle converts energy stored in food to the energy a cell can use to live and function. It is known as the 'powerhouse' of the cell.
What is the mitochondria?
Every cell is surrounded by this.
What is a cell membrane?
This is the type of cell transport that DOES NOT require energy.
What is passive transport?
This invention made the discovery of cells possible.
What is a microscope?
This is the outer layer of a plant cell that provides support and protection.
What is a cell wall?
This organelle is found in the cells of plants and some other organisms; it captures energy from sunlight and changes it to an energy that cells can use in making food.
What are chloroplasts?
This means that some substances can cross the cell membrane while others cannot.
What is selectively permeble?
This is the type of transport that DOES require energy.
What is active transport?
A widely accepted explanation of the relationship between cells and living things.
What is the cell theory?
This is the organelle that contains the cell's genetic information and controls the cell's activities.
What is the nucleus?
These organelles contain substances that break down large food particles into smaller ones. They also break down old cell parts and release them as waste.
What are lysosomes?
This is the movement of molecules from an area of high concentration to an area of lower concentration.
What is diffusion?
This process takes particles into the cell by changing shape and engulfing the particles.
What is endocytosis?
True or false: All living things are made of cell(s).
True
This organelle is a network of membranes that processes proteins and lipids. Sometimes there are ribosomes attached.
What is the endoplasmic reticulum?
This organelle stores water, food and other materials. It is larger in a plant cell.
What is a vacuole?
This is the diffusion of WATER molecules across a selectively permeable membrane.
What is osmosis?
List the three types of passive transport.
What are diffusion, osmosis, and facilitated diffusion?
Light microscopes focus light through lenses to produce magnified images, while electron microscopes use this.
What are beams of electrons?
This organelle receives proteins and other materials, packages hem, and distributes them around the cell.
What is the Golgi apparatus?
A group of cells that work together to perform a specific function.
What are tissues?
This is a type of passive transport that utilizes a protein channel.
What is facilitated diffusion?
The odor from a skunk can be sensed from farther away due to this.
What is diffusion?
