Cells
This gel-like substance fills the inside of a cell.
What is cytoplasm?
Animal cells have a large organelle that stores DNA and is like the main office of a factory. What is it called?
What is the nucleus?
This outer protective covering gives the plant cell a rigid shape.
What is the cell wall?
This process moves small particles from an area of higher concentration to an area of lower concentration without using energy.
What is diffusion?
The scientific theory that all living things are made of cells, that the cell is the basic unit of life, and that all cells come from other cells.
What is Cell Theory?
All cells, even bacteria, have four parts in common. Name any one.
What is a cell membrane, cytoplasm, DNA, or ribosomes?
Organelles that convert nutrients into usable energy, like a factory’s power plant, are called what?
What are mitochondria?
This organelle uses sunlight to make sugar for the plant cell.
What is chloroplast?
This is diffusion with the help of protein channels for particles that are too large to pass through the membrane on their own.
What is facilitated diffusion?
An organisms having or consisting of multiple cells
What is Multicellular?
This cell structure makes proteins by following instructions in DNA.
What are ribosomes?
Organelles that store materials for the cell to use later.
What are Vacuoles?
This large organelle stores water and helps the plant cell maintain its shape.
What is the central vacuole?
This process moves particles from an area of lower concentration to an area of higher concentration and requires energy.
What is active transport?
An organism having or consisting of a single cell
What is Unicellular?
The cell membrane is selectively permeable. What does this mean?
What is it lets some particles pass through while blocking others?
Organelles that break down waste and recycle materials in the cell.
What are Lysosomes?
The green pigment inside chloroplasts that absorbs sunlight.
What is chlorophyll?
This process allows a cell to take in very large particles by folding the membrane inward to form a pouch.
What is endocytosis?
nonliving particle that makes copies of itself inside living cells; can cause diseases in some cases.
What is a virus?
Name all four parts found in every cell
What are a cell membrane, cytoplasm, DNA, and ribosomes?
This organelle, often found surrounding the nucleus, helps make some cell parts and transports them to other parts of the cell.
What is the endoplasmic reticulum (ER)?
How do the cell wall and central vacuole work together to keep a plant upright?
What is the vacuole fills with water, pushing the cytoplasm and cell membrane against the cell wall, which keeps the cell rigid and supports the plant?
This process moves large particles or many particles out of a cell by wrapping them in a membrane and fusing with the cell membrane.
What is exocytosis?
List the three main components of the Cell Theory.
All living things are made of one or more cells?
Cells are the basic unit of life?
All cells come from existing cells?
