Cell Theory
This basic unit of life is the core building block of all living organisms.
What is a CELL
Unlike animal cells, plant cells have this rigid, outermost layer made of cellulose for structural support.
What is CELL WALL
Unlike plants, animal cells lack a cell wall and rely on this flexible outer barrier to control what enters and leaves.
What is CELL MEMBRANE
While both cell types have this organelle to generate energy, only plant cells also have chloroplasts to capture it from the sun.
What is the mitochondria
This tiny, non-membrane-bound structure is found in both prokaryotic and eukaryotic cells and is responsible for protein synthesis.
What is a ribosome
According to cell theory, all cells arise only from these pre-existing structures.
What are PRE- EXISTING CELLS
Plant cells use these green, solar-powered organelles to perform photosynthesis.
What are chloroplasts
Animal cells have many small versions of these storage sacs, unlike the single massive central one found in plants.
What are vacuoles
If you look at them under a microscope, animal cells are usually irregular or round, while plant cells have a rigid, fixed shape resembling a box.
What is rectangular? (Also accept: square)
This organelle consists of a stack of flattened membranes that sorts, tags, and packages proteins for delivery outside the cell.
What is the Golgi apparatus
In the 1660s, this English scientist coined the term "cell" after looking at a slice of cork under a microscope.
Who is ROBERT HOOKE
This massive central organelle stores water and creates turgor pressure to keep the plant crisp and upright.
What is the large central vacuole
These specialized animal cell organelles contain digestive enzymes to break down waste and cellular debris.
What are lysosomes?
Both cells are classified under this domain of life, meaning they possess a true nucleus and membrane-bound organelles.
What are eukaryotes
Cell theory was temporarily challenged by the discovery of these infectious agents, which contain genetic material but cannot reproduce without a host cell.
What are viruses
These two German scientists, one a botanist and one a zoologist, concluded in the late 1830s that all plants and animals are made of cells.
Who are Matthias Schleiden and Theodor Schwann
This pigment molecule inside the chloroplast absorbs sunlight and gives plants their green color.
What is chlorophyll
Found only in animal cells, this barrel-shaped organelle pair helps organize spindle fibers during cell division.
What are centrioles
This cell organelle makes proteins for the cell.
What is Ribosomes
This specialized region located inside the nucleus is responsible for assembling the components of ribosomes
What is NUCLEOLUS
This Dutch scientist improved the microscope and was the first to observe live cells, which he called "animalcules."
Who is Anton van Leeuwenhoek
This complex carbohydrate is the primary structural component used to build a plant's rigid cell wall.
What is CELLULOSE
When an animal cell is placed in pure water, it will absorb water until it bursts, a destructive process known by this 4-letter scientific term
What is LYSE
This organelle is called the intracellular highway for both cells and aids in making lipids and transporting ribosomes.
What is Endoplasmic Reticulum (ER)
This cell organelle is the Brain of your cell and holds genetic information
What is the NUCLEUS
