B
What is the tool we use to observe cells?
Microscopes
Give a short description of a prokaryotic & eukaryotic cell.
Prokaryotic Cell: Simple unicellular organism
Eukaryotic Cell: Complex uni- or multicellular organism
Which organelle is the control center of the cell and holds DNA?
Nucleus
Which cell organelle organelle allows things in and out of the cell?
Cell Membrane
Is a thick, clear, jelly-like substance present inside the cell membrane.
Cytoplasm
The scientist who concluded that all animals are made up of cells.
Theodor Schwann
How do prokaryotic and eukaryotic cells differ?
Prokaryotic Cells:
Small, No membrane bound organelles
Eukaryotic Cells:
Large, Membrane bound organelles
What organelle produces energy for the cell and is known as the power house?
Mitochondria
This gel-like substance holds organelles in place.
Cytoplasm
It controls the movement of substances in and out of the cells. It separates the cell from the external environment.
Cell Membrane/ Plasma Membrane
He advanced the cell theory with his conclusion that cells could only come from other cells:
Rudolf Virchow
What is something that prokaryotic and eukaryotic cells have in common?
Cell membrane, DNA, Ribosomes, Cytoplasm
This organelle stores water, food, and nutrients for the cell.
Vacuole
This organelles makes proteins for the cell.
Ribosomes
The primary organelles for photosynthesis. It contains the pigment chlorophyll.
Chloroplasts
He discovered that all plants were made of cells, which contributed to the development of the cell theory.
Matthias Schleiden
Give at least one example of a eukaryotic cell.
Animal Cell
Plant Cell
Fungi
This organelle is responsible for processing and moving materials around the cell.
Endoplasmic Reticulum (E.R.)
This organelle packages and transmits cellular material throughout the cell.
Golgi Body
it is involved in the transportation of materials within the cell
Golgi Bodies/Apparatus
A German zoologist, concluded that all animals are composed of cells.
Theodore Schwann
Give at least one example of a prokaryotic cell.
Bacteria Cell and Archaea
These two organelles are only in plant cells. One provides support and structure, while the other catches sunlight and adds photosynthesis.
Cell Wall & Chloroplast
This organelle is responsible for removing waste from the cell.
Lysosomes
The postulates of the cell theory are:
a. Cell is the basic unit of life
b. All organisms are made up of cell
c. Cell comes from pre-existing cell
