Plant Cells
This rigid outer layer surrounds plant cells and helps support and protect the plant
Cell Wall
This structure is semi-permeable
Cell Membrane
This term describes an organism made of only one cell
Unicellular
This scientist was the first to observe cells under a microscope and called them “little rooms.”
Robert Hooke
This organelle is larger in Plant cells than animals
Vacuole
This jelly-like substance fills the cell and holds all the organelles in place
Cytoplasm
Unlike unicellular organisms that are made of just one cell, these organisms are usually larger because they are made of many cells working together
Multicellular Organisms
This scientist concluded that all plants are made of cells.
Matthias Schleiden
What is the function of the Chloroplast?
Converts light energy from the sun into sugars to be used for energy in a process called photosynthesis
This organelle acts like a transportation system inside the cell, moving proteins and other materials from one part of the cell to another.
Endoplasmic Reticulum
This type of organism includes humans, dogs, and trees
Multicellular
This scientist improved the microscope and observed single-celled organisms, calling them “animalcules.”
Anton Van Leeuwenhoek
This structure controls what enters and leaves the plant cell and is found in both plant and animal cells
Cell Membrane
These tiny structures inside the cell make proteins
Ribosomes
These tiny organisms are unicellular and can be found almost everywhere on Earth, including soil, water, and inside our bodies.
Bacteria
This principle of cell theory explains why every living thing starts with cells and grows by producing new cells.
all cells come from preexisting cells
This organelle contains the plant cell’s DNA and acts as the control center for the cell
Nucleus
This organelle modifies, packages, and ships proteins to other parts of the cell
Golgi Apparatus
This German scientist stated that cells are the basic unit of structure and function in all living things.
