Bio Exam 2 (Chapter 6) Flashcards
What type of cell is in protists, fungi, animals, and plants?
Eukaryotic Cells
What type of cell is in bacteria and archaea?
Prokaryotic Cells
What is the interior of any cell?
Cytoplasm
What houses the cell’s DNA in a eukaryotic cell?
Nucleus
What uses info from DNA to make proteins?
Ribosome
What is a double membrane that encloses the nucleus?
Nuclear envelope
What structures carry the genetic information?
Chromosomes
What are the proteins that make up chromosomes?
Chromatin
What separates the cell into different compartments, or organelles, such as the nucleus, the endoplasmic reticulum (ER), the Golgi apparatus, and lysosomes
Endomembrane System
What is a network of membranous tubules within the cytoplasm of a eukaryotic cell, continuous with the nuclear membrane
Endoplasmic Reticulum
What part of the Endoplasmic Reticulum is involved in metabolic processes and the synthesis of lipids?
Smooth Endoplasmic Reticulum
What part of the Endoplasmic Reticulum is involved in the synthesis of proteins?
Rough Endoplasmic Reticulum
What is a biological structure that performs a distinctive function inside a cell
Organelle
What is an organelle in eukaryotic cells that consist of flat membranous sacs that modify, store, and route products of the Endoplasmic Reticulum and synthesize products?
Golgi Apparatus
What is a membranous sac of hydrolytic enzymes that eukaryotic cells use to digest (hydrolyze) macromolecules?
Lysosome
What are large vesicles derived from the endoplasmic reticulum and Golgi apparatus?
Vacuoles
What is the site of cellular resipiration?
Mitochondria
What is the site of photosynthesis?
Chloroplast
What is a network of fibers extending throughout the cytoplasm that gives mechanical support to the cell and helps with cell motility (movement)?
Cytoskeleton
What are cellular extensions that contain microtubules that assist in moving the cell?
Flagella and cilia
What is regarded as the boundary of the living cell?
Plasma membrane
What is the extracellular structure of plant cells, distinguishes plant cells from animal cells?
Cell Wall
What are the main differences between prokaryotic and eukaryotic cells?
Prokaryotic cell does not have a nucleus.
What are specialized metabolic organelles that are involved in oxidative reactions?
Peroxisomes
What is an important source of energy for cellular processes?
ATP
