(10 cards)
Prokaryote
A type of cell that is very simple and does not have a nucleus. The DNA is not inside a special membrane but floats in the cell. Ex: bacteria
Eukaryote
A type of cell that is more complex and has a nucleus, where the DNA is stored.
Ex: plants, animals, fungi, and protists
Organelles
are tiny structures that carry out specific functions within a cell.
Chloroplast
is an organelle within the cells of plants and certain algae that is the site of photosynthesis.
Mitochondria
are organelles in cells that produce energy for the cell. They are called the powerhouse of the cell.
Vacuoles
are the storage areas of cells.
is the strong outer layer of a plant cell that protects it and gives it shape and support. It helps the plant stand tall and keeps the cell safe. Animal cells do not have a cell wall.
Cell Wall
is like a gatekeeper for the cell. It controls what goes in and out, letting certain things in and keeping certain things out. It also helps hold the cell together.
Cell Membrane
is the jelly-like fluid inside a cell that holds all the organelles in place. It helps the cell keep its shape and allows nutrients and other materials to move around.
Cytoplasm
Centrioles
are tiny helpers in the cell that help it divide and make new cells. They help organize the parts that pull the cell apart during cell division.
