(24 cards)
What is a cell?
The smallest structure and functional unit of an organism
A unicellular organism who lacks a nucleus and other membrane-bound organelles is called?
Prokaryote
What houses DNA and regulates cell activities
The Nucleus
A unicellular or multicellular organism whose cell(s) have a nucleus and other membrane-bound organelles is called a __________.
Eukaryote
What digests damaged ribosomes and breaks down macromolecules
Lysosome
What creates cellular energy by breaking down and storing ATP
Mitochondria
What organelle sorts, packages, and ships molecules in vesicles
Golgi body also known as “ the post office”
What creates glucose through photosynthesis?
Chloroplast
What provides structural support , rigidity, and protects the plant cell from the external environment?
The cell wall
What organelle makes proteins
Ribosome
What organelle digests long chain fatty acids using oxidative enzymes
Peroxisome
What organelle has a site where a polypeptide is modified and transported.
Rough Endoplasimic reticulum (ER)
What organelle makes lipids
Smooth Endoplasmic reticulum
What organelle gets rid of damaged proteins
Proteosome
What organelle enables movement
Flagella
What organelle regulates the transport of materials entering and exiting the cell
Cell membrane
What organelle is gell - like fluid in a cell, supports & suspends organelles & cellular molecules
Cytoplasm
What organelle helps transport materials that an organism needs to survive and recycle waste materials
Vesicles
What organelle produces and assembles the cell’s ribosomes
Nucleolus
What organelle plays a role in organizing microtubules that serves as the cell’s skeletal system. Also, help determine the locations of the nucleus and other organelles within the cell.
Centrioles
What organelle helps cells maintain their shape and internal organization. Also provides mechanical support that enables cells to carry out essential functions like division and movement.
Cytoskeleton
What organelle helps maintain water balance in plant cells. Help sequencer waste products in animal cells.
Vacuoles
What organelle is short hair-like structures on the surface of prokaryotic cells. Have a role in movement.
Pilius
What organelle move water relative to the cell in a regular movement of the cilio.
Cila
