About the Cell
Any living thing that carries out its own life processes
an organism?
This surrounds the cell. A protective layer that controls materials moving into and out of the cell
the cell membrane
The region inside the cell that includes the fluid and all the organelles except the nucleus.
the cytoplasm
What organelle captures the sun's energy to make food
Chloroplast
These are the 2 types of cells:
prokaryote and eukaryote
This is the smallest functional and structural unit of all living organisms.
a cell
This contains the DNA.
the nucleus
The cytoskeleton is used to give shape and ______ to the cells.
support
This organelle packages and distributes materials to the cell.
the golgi complex
This type of cells don´t have a nucleus:
prokaryote cells
This is an organism made up of one cell
an unicellular organism
A small body in the cytoplasm that is specialized to perform a specific function.
an organelle
In the plant cell this surrounds the cell and provides support and protection.
cell wall
In eukaryotic cells, which organelle contains the DNA
the nucleus
Tell whether the following statement is true or false:
- Prokaryotic cells can be unicellular or multicellular.
False
This part of the cell packages and transports materials throughout the cell
Golgi Apparatus
What is the main difference between prokariotic and eukaryotic cells?
Prokaryotic cells don´t have a nucleus but Eukaryotic cells do.
Ribosomes make proteins, but ribosomes themselves are made in this organelle.
Nucleolus
Who was the first scientist to discover plant cells?
Matthias Schleiden
Tell whether the follwing statement is true or false:
- All cells have DNA at some point in their lives.
True
Organisms made up of cells that contain DNA in a nucleus, membrane-bound organelles, and ribosomes.
Eukaryote
Ribosomes make these in the cell:
proteins
Plant cells have these additional parts that the animal cell does not.
cell wall, chloroplast
Who were the three scientists responsible for the cell theory?
Robert Hooke, Matthias Schleiden, Theodor Schwann
