Organelles
This organelle is known as the "powerhouse" of the cell because it produces energy for the cell.
Mitochondrion (plural: Mitochondria)
The fundamental unit of structure and function in all living organisms.
Cell
The rigid structure outside the cell membrane that gives plant cells extra support and protection.
Cell wall
The ___________ of the animal cell is variable and flexible, whereas the plant cell is fixed and rigid.
shape
True or false: Prokaryotic cells do not have a defined nucleus.
True.
The organelle where proteins are made; it can be free in the cytoplasm or attached to the endoplasmic reticulum.
Ribosome
According to cell theory, cells come from the __________ of existing cells. (Fill in the blank.)
What is division?
The large sac in plant cells that stores water and helps maintain pressure inside the cell.
Vacuole
Small structures that contain digestive enzymes and help break down waste and worn-out cell parts in animal cells.
Lysosomes
The simplest type of cell lacking membrane-bound organelles; give one example of an prokaryote.
Bacteria
This organelle modifies, sorts, and packages proteins and lipids for storage or transport out of the cell.
Golgi Body or Golgi Apparatus
The cell theory states that all living things are made of these basic units.
What is a cell?
What structure surrounds animal cells and controls what enters and leaves the cell?
Animal cells have many of these, while plant cells only have one.
Vacuole
Many prokaryotes have a tough outer layer that helps them survive harsh conditions. What is this structure called when present outside the cell membrane (not all have it)?
Capsule
A system of folded membranes covered with ribosomes that helps make and transport proteins
Rough endoplasmic reticulum (Rough ER)
Which instrument was essential for the development of cell theory?
Microscope
This plant cell organelle makes proteins.
Ribosome
What flexible structure surrounds animal cells and controls what enters and leaves the cell?
Cell membrane
Eukaryotic cells are typically about how much larger than prokaryotic cells?
10 times
This organelle is primarily water.
Cytoplasm
A modern addition to the theory: Cells contain this, which is passed during division.
Hereditary information (or DNA)
The large sac in plant cells that stores water and helps maintain pressure inside the cell.
Chloroplasts, cell wall.
What organelle to animal cells have that plant cells lack?
Lysosomes (and centriole)
Prokaryotes like bacteria have this instead of a nucleus.
