Anatomy and Physiology
What is the control center of the cell?
Nucleus
What controls what enters and exits the cell?
Plasma membrane
What organelle is the “Power House” of the cell?
Mitochondria
Which organelle makes protein?
Ribosomes
Which organelle packages proteins?
Golgi Body
Which of the following is not one of the four most abundant elements in the body?
Sodium
Two types of passive transport are?
Diffusion and Filtration
Passive processes that move substances across membranes _______ __ ___
Require no ATP
A cell with abundant peroxisomes would most likely be involved in?
Detoxification activites
In order for diffusion to occur, there must be equal concentration on both sides of the selectively permeable membrane
False
What structure in the nucleus assembles ribosomes?
Nucleoli
What organelle is the center for cellular digestion?
Lysosomes
Which organelle manufactures CHO and packages sections?
Golgi Apparatus
For filtration to occur, there must be a concentration gradient
False
Which movement of substance across the cell membrane requires energy?
Bulk transport
Which type of bulk transport brings extracellular substances inside the cell?
Endocytosis
Water accounts for what percent of cytoplasm?
70-80%
Both prokaryotic and eukaryotic contain a nucleus
False
What area of the cell is considered the “factory area” and allows for biochemical reactions to occur?
Golgi Apparatus
Ribosomes are located in the cytoplasm and _____ ___________ _________
Rough Endoplasmic Recticulum
The solution outside the cell membrane is called interstitial fluid
True
Which organelle serves as the “shipping center” of the cell?
Golgi Apparatus
The role of the cytoskeleton are to provide support, stability, intracellular transport, and ___________
Contraction
The role of vesicles is to transport specific materials between the organelles and the cell membrane
True
Which cells are considered the “breakdown” bodies?
Lysosomes
Which form of diffusion requires a protein carrier?
Facilitated
It is generally around the nucleus and is the principle “traffic director” for cellular proteins
Golgi Apparatus
The nucleus membrane encloses a jelly-like substance called cytoplasm
False
During cellular mitosis, which organelle turns into chromosomes?
Chromatin
Which organelles capture and distribute materials for degradation, recycling, or their incorporation into metabolic pathways?
Peroxisomes
In the plasma membrane, both the phospholipids and cholesterol are hydrophobic
False
During cellular division, which organelle direct formation of the mitotic spindle?
Centrioles
In bulk transport, phagocytosis is called “cell eating”
True
