Flashcards in Cell Structure and Function Deck (16):
1

Name the three major components of the cell.

The plasma membrane, the nucleus, and the cytoplasm

2

Which organelle is responsible for ATP production?

Mitochondria

3

Which organelle in the cell produces lipids, stores calcium and is reaponsible for detox functions?

Smooth endoplasmic reticulum

4

What cellular structure houses the DNA that controls the function of the cell?

The nucleus

5

What cellular structure is responsible for ribosome production?

The nucleolus

6

How is the rough endoplasmic reticulum related to the Golgi complex in terms of function?

The Golgi complex receives proteins from the Rough "ER" then modifies, packages, and sorts the proteins for delivery to other organelles.

7

Which (2) organelles produce proteins?

Ribosomes (2 types) and Rough "ER"

8

What is the function of the cytoskeleton?

It provides the internal framework that gives the cell its unique shape, comprised of a system of fibers and tubules that anchor organelles and form compaetments and passageways

9

What is the liquid portion of the cytoplasm called?

Cytosol

10

What structure in the cell is composed mostly of a phospholipid bilayer?

Plasma membrane

11

Cholesterol is vital for the structural integrity of what cellular structure?

Plasma membrane

12

Name the two major phases of the Cell Cycle.

Interphase and the Mitotic (M) phase

13

Name the three phases of interphase.

G1 phase, S phase, and G2 phase

14

Name the process of the division of the cytoplasm in the M phase of the cell cycle.

Cytokinesis (which begins in Anaphase and ends in Telephase)

15

In what phase of mitosis do the chromosomes split apart?

Anaphase

16

What are the four phases of nuclear (mitotic) division?

In order of occurrence:
Prophase, Metaphase, Anaphase, and Telophase
