Cells & Cell Theory
The basic unit of structure and function in all living things.
What is a cell?
This organelle controls all cell activities and contains genetic material.
What is the nucleus?
This green organelle allows plants to make their own food through photosynthesis.
What is the chloroplast?
True or False: ALL living things breathe oxygen
An organism made up of only one cell is called what?
What is unicellular?
The scientist who called the organisms he saw in pond water "animalcules"
Who is Anton Von Leeuwenhoek?
This gel-like material fills the cell and holds the organelles in place.
What is the cytoplasm?
This thick outer layer gives plant cells structure and support.
What is the cell wall?
What is abiotic
This type of scientific knowledge explains why things happen in nature and can change with new evidence.
What is a theory?
Microscopic single-celled organisms that do not have a nucleus.
What are prokaryotic cells?
These organelles are known as the “powerhouses” of the cell because they produce energy.
What are mitochondria?
Plant cells have one large one of these to store water; animal cells have many small ones.
What is a vacuole?
He was the first person to see and describe cells as "cells"
Who is Robert Hooke?
Give one example of a unicellular organism and one example of a multicellular organism.
Unicellular: Amoeba or bacteria; Multicellular: Human or tree.
Multi-cellular or single-celled organisms that have a nucleus and membrane-bound organelles.
What are eukaryotic cells?
This cell part is found in all cells and controls what enters and leaves the cell.
What is the cell membrane?
This organelle controls the passage of materials in and out of the nucleus
What is the nuclear membrane?
True or False: Mold is alive
TRUE!
The invention and improvement of this technology helped scientists discover and study cells.
What is the microscope?
The 3 tenants of the Cell Theory?
This theory states that all living things are made of one or more cells, cells are the basic unit of life, and all cells come from pre-existing cells.
This organelle helps fold, package and transport proteins and lipids to be used throughout the cell.
What is the endoplasmic reticulum?
This organelle is responsible to forming spidles that move chromosomes during mitosis (cell reproduction)
What are centrioles?
An owl developing night vision over generations to hunt better is an example of this characteristic of life
What is adapt/evolve?
Maintaining stable internal conditions
What is homeostasis
