Cell Basics
This is the basic unit of life.
The cell
This cell structure controls what enters and leaves the cell.
What is a cell membrane
This organelle makes proteins.
What is the ribosome
This molecule contains the genetic instructions for a cell.
What is DNA?
This means a membrane allows some materials to pass through but blocks others.
What is selectively permeable?
This green pigment helps plants capture sunlight.
What is chlorophyll?
Compare photosynthesis and cellular respiration by explaining what each process uses, what each process produces, and why both are important for living things.
Photosynthesis uses sunlight, water, and carbon dioxide to produce sugar/glucose and oxygen. Cellular respiration uses sugar/glucose and oxygen to produce carbon dioxide, water, and ATP energy. They are important because photosynthesis makes food and oxygen, while cellular respiration releases usable energy cells need to live.
This theory states that all living things are made of cells, cells are the basic unit of life, and cells come from other cells.
what is cell theory
This stiff outer layer supports and protects plant cells.
What is the Cell Wall
This organelle releases energy from food for the cell.
What is the mitochondrion?
This is a tightly packed structure made of DNA.
What is a chromosome?
This is the movement of particles from high concentration to low concentration.
What is diffusion?
This process uses sunlight, water, and carbon dioxide to make sugar and oxygen.
What is photosynthesis?
A group of similar cells working together to do a specific job is called this.
What is tissue
This jelly-like material holds the organelles inside the cell.
What is cytoplasm
This organelle packages and ships materials in the cell.
What is the Golgi apparatus?
This is a small structure inside a cell that has a specific job.
What is an organelle?
This is the movement of water across a membrane.
What is osmosis?
This process breaks down sugar and oxygen to release ATP energy.
What is cellular respiration?
A body structure made of different tissues working together is called this.
What is an organ?
This whip-like structure helps some cells move.
What is a flagellum?
This folded membrane system helps move materials through the cell.
What is the endoplasmic reticulum?
This network of fibers helps the cell keep its shape and move materials inside the cell.
What is the cytoskeleton?
This type of transport does not require energy.
What is passive transport?
This molecule stores and carries usable energy for cells.
What is ATP?
Explain the difference between a tissue and an organ.
A tissue is a group of similar cells working together, while an organ is made of different tissues working together to perform a job.
Explain the difference between the cell membrane and the cell wall.
The cell membrane controls what enters and leaves the cell, while the cell wall gives support and protection to plant cells, fungi, and some bacteria.
A cell has many old, worn-out parts that need to be broken down and recycled. Which organelle would do this job?
What is the lysosome?
Explain the relationship between DNA and chromosomes.
DNA contains genetic instructions, and chromosomes are tightly packed structures made of DNA.
A cell moves materials from low concentration to high concentration and uses energy. What process is happening?
What is active transport?
Explain how photosynthesis and cellular respiration are connected.
Photosynthesis produces sugar and oxygen, which are used in cellular respiration. Cellular respiration produces carbon dioxide and water, which can be used in photosynthesis.
